    Advancing Eddy Parameterizations: Dynamic Energy Backscatter and the Role of Subgrid Energy Advection and Stochastic Forcing (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-04-26
    Description: Viscosity in the momentum equation is needed for numerical stability, as well as to arrest the direct cascade of enstrophy at grid scales. However, a viscous momentum closure tends to over-dissipate eddy kinetic energy. To return excessively dissipated energy to the system, the viscous closure is equipped with what is called dynamic kinetic energy backscatter. The amplitude of backscatter is based on the amount of unresolved kinetic energy (UKE). This energy is tracked through space and time via a prognostic equation. Our study proposes to add advection of UKE by the resolved flow to that equation to explicitly consider the effects of nonlocality on the subgrid energy budget. UKE can consequently be advected by the resolved flow before it is reinjected via backscatter. Furthermore, we suggest incorporating a stochastic element into the UKE equation to account for missing small-scale variability, which is not present in the purely deterministic approach. The implementations are tested on two intermediate complexity setups of the global ocean model FESOM2: an idealized channel setup and a double-gyre setup. The impacts of these additional terms are analyzed, highlighting increased eddy activity and improved flow characteristics when advection and carefully tuned, stochastic sources are incorporated into the UKE budget. Additionally, we provide diagnostics to gain further insights into the effects of scale separation between the viscous dissipation operator and the backscatter operator responsible for the energy injection. Oceanic swirls or "eddies" have a typical size of 10-100 km, which is close to the smallest scales that global ocean models commonly resolve. For physical and numerical reasons, these models require the addition of artificial terms that influence the flow near its smallest scales. Common approaches have the drawback of introducing systematic loss of kinetic energy contained in the eddies, which leads to errors that also affect the oceanic circulation on global scales. In our research, we compensate for this error by returning some of the missing energy back into the simulation, using a so-called kinetic energy backscatter scheme. In this work, we continue the development of an already existing and successful backscatter scheme, adding certain improvements to the way energy is budgeted and returned to the flow: we ensure that the local energy budget is attached to each fluid parcel as it is transported by the large-scale flow, and we also add a random forcing term that mimics unknown sources of such energy to bring its statistical properties closer to reality. We demonstrate that these modifications effectively improve the characteristics of the simulated flow. Extension of the subgrid energy equation of the kinetic energy backscatter parameterization by adding advection and a stochastic term Both additional terms improve several flow characteristics in two idealized test cases, a channel and a double-gyre Scale analysis reveals the necessity of sufficient scale separation between viscous energy dissipation and energy injection via backscatter. Key Points: - Extension of the subgrid energy equation of the kinetic energy backscatter parameterization by adding advection and a stochastic term - Both additional terms improve several flow characteristics in two idealized test cases, a channel and a double-gyre - Scale analysis reveals the necessity of sufficient scale separation between viscous energy dissipation and energy injection via backscatter

    Impact of the North Atlantic Oscillation on the Decadal Variability of the Upper Subtropical‐Tropical Atlantic Ocean (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-04-29
    Description: In the northeastern tropical Atlantic, a region of high potential vorticity (PV) determines the size of the exchange window for the interior thermocline flow of the subtropical cell via its variations in strength and extent. Variability of this PV barrier has the potential to impact the ventilation of the tropical Atlantic on decadal timescales. Here, the impact of the North Atlantic Oscillation (NAO) on the PV barrier related to isopycnals within the thermocline of the subtropical-tropical Atlantic Ocean is assessed from Argo observations for the time period of 2006-2022. Relative to the negative NAO phase (2009-2010), during the positive NAO phase (2014-2019), the North Atlantic subtropical high and the northeast trades are intensified. Satellite-derived wind stress curl shows increased upwelling/downwelling on the equatorward/poleward side of the trade wind zone, respectively. In the subtropical-tropical Atlantic, a symmetric pattern of isopycnal heave is observed: rising isopycnals within 20 degrees N and 20 degrees S and sinking poleward of that. With rising isopycnals, the PV barrier in the northeastern tropical Atlantic becomes stronger. Analyses of geostrophic velocities and the Sverdrup streamfunction show that during the positive NAO phase there are increased equatorward velocities at thermocline level along the western boundary and reduced velocities through the interior as a result of intensified northeast trades and therefore a strengthened PV barrier. Intensified trades lead to enhanced subduction of thermocline waters and, independent of that, to a strengthened Equatorial Undercurrent transport as observed at the mooring site at 0 degrees, 23 degrees W, likely via the pulling effect of the subtropical cells. In the North Atlantic Ocean, subducted water from the subtropics has two possible pathways within the thermocline toward the equatorial region: the interior pathway and the pathway along the western boundary. The size of the exchange window between subtropics and tropics depends on the extent of a barrier zone in the eastern part of the basin that is associated with wind-driven upwelling of density surfaces. The North Atlantic Oscillation (NAO) is the dominant atmospheric climate mode in the North Atlantic and in this study, we show how the NAO impacts the barrier for the equatorward thermocline flow in the tropical Atlantic Ocean. During positive NAO phases (e.g., 2014-2019), density surfaces become shallower and strengthen the barrier, while during negative NAO phases (e.g., 2009-2010) the barrier weakens. Geostrophic velocity analysis reveals that during positive NAO phases more thermocline water is transported equatorward via the western boundary and less via the interior pathway. Additionally, observations from a mooring site at 0 degrees, 23 degrees W show stronger Equatorial Undercurrent transport as a result of intensified trade winds during positive NAO phases. Trade winds in the northeastern tropical Atlantic strengthen during positive phases of the North Atlantic Oscillation (NAO+) Potential vorticity barrier for the interior equatorward thermocline flow of the North Atlantic Subtropical Cell strengthens during NAO+ Annual subduction of thermocline water and Equatorial Undercurrent transport increase simultaneously from 2008 to 2018

    Whales and cephalopods in a deep‐sea arms race (2024)
    ASLO (Association for the Sciences of Limnology and Oceanography) | Wiley
    Details
    Publication Date: 2024-05-06
    Description: Scientific Significance Statement Millions of predator–prey interactions between deep-diving toothed whales and cephalopods occur daily in the dark deep sea. While predatory whales developed traits to detect and hunt their prey, cephalopods had to expand their anti-predatory strategies specialized for visual predators, to counteract acoustic predators. Since toothed whale-cephalopod interactions have never been directly observed in the deep sea, it remains unknown what selective pressures and traits evolved from this arms race. Combining current knowledge, we formalize four hypotheses and associated research approaches that will guide future investigation on oceanic predator–prey systems. We identify whale echolocation as an unprecedented armament to hunt distant prey and propose that deep-sea squids avoid acoustic predators by (1) reducing their acoustic cross-section through body shape and posture, (2) deep-sea migration, and (3) not schooling. Toothed whale predation emerges as a potential driver of the cephalopod live-fast-die-young strategy—which may now leave cephalopods at competitive advantage under global change.

    Testing the deep‐sea glacial disturbance hypothesis as a cause of low, present‐day Norwegian Sea diversity and resulting steep latitudinal diversity gradient, using fossil records (2024)
    Wiley
    Details
    Publication Date: 2024-05-06
    Description: Aims Within the intensively‐studied, well‐documented latitudinal diversity gradient, the deep‐sea biodiversity of the present‐day Norwegian Sea stands out with its notably low diversity, constituting a steep latitudinal diversity gradient in the North Atlantic. The reason behind this has long been a topic of debate and speculation. Most prominently, it is explained by the deep‐sea glacial disturbance hypothesis, which states that harsh environmental glacial conditions negatively impacted Norwegian Sea diversities, which have not yet fully recovered. Our aim is to empirically test this hypothesis. Specific research questions are: (1) Has deep‐sea biodiversity been lower during glacials than during interglacials? ( 2) Was there any faunal shift at the Mid‐Brunhes Event (MBE) when the mode of glacial–interglacial climatic change was altered? Location Norwegian Sea, deep sea (1819–2800 m), coring sites MD992277, PS1243, and M23352. Time period 620.7–1.4 ka (Middle Pleistocene–Late Holocene). Taxa studied Ostracoda (Crustacea). Methods We empirically test the deep‐sea glacial disturbance hypothesis by investigating whether diversity in glacial periods is consistently lower than diversity in interglacial periods. Additionally, we apply comparative analyses to determine a potential faunal shift at the MBE, a Pleistocene event describing a fundamental shift in global climate. Results The deep Norwegian Sea diversity was not lower during glacial periods compared to interglacial periods. Holocene diversity was exceedingly lower than that of the last glacial period. Faunal composition changed substantially between pre‐ and post‐MBE. Main conclusions These results reject the glacial disturbance hypothesis, since the low glacial diversity is the important precondition here. The present‐day‐style deep Norwegian Sea ecosystem was established by the MBE, more specifically by MBE‐induced changes in global climate, which has led to more dynamic post‐MBE conditions. In a broader context, this implies that the MBE has played an important role in the establishment of the modern polar deep‐sea ecosystem and biodiversity in general.

    Costs of Dust Collection by Trichodesmium : Effect on Buoyancy and Toxic Metal Release (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-05-06
    Description: The marine cyanobacterium Trichodesmium has the remarkable ability to interact with and utilize air‐borne dust as a nutrient source. However, dust may adversely affect Trichodesmium through buoyancy loss and exposure to toxic metals. Our study explored the effect of desert dust on buoyancy and mortality of natural Red Sea puff‐shaped Trichodesmium thiebautii . Sinking velocities and ability of individual colonies to stay afloat with increasing dust loads were studied in sedimentation chambers. Low dust loads of up to ∼400 ng per colony did not impact initial sinking velocity and colonies remained afloat in the chamber. Above this threshold, sinking velocity increased linearly with the colony dust load at a slope matching prediction based on Stoke's law. The potential toxicity of dust was assessed with regards to metal dissolution kinetics, differentiating between rapidly released metals, which may impact surface blooms, and gradually released metals that may impact dust‐centering colonies. Incubations with increasing dust concentrations revealed colony death, but the observed lethal dose far exceeded dust concentrations measured in coastal and open ocean systems. Removal of toxic particles as a mechanism to reduce toxicity was explored using SEM‐EDX imaging of colonies incubated with Cu‐minerals, yet observations did not support this pathway. Combining our current and former experiments, we suggest that in natural settings the nutritional benefits gained by Trichodesmium via dust collection outweigh the risks of buoyancy loss and toxicity. Our data and concepts feed into the growing recognition of the significance of dust for Trichodesmium 's ecology and subsequently to ocean productivity. Plain Language Summary Trichodesmium spp. are abundant cyanobacteria, forming extensive blooms in low latitude warm oceans, and contribute significantly to carbon (C) and nitrogen (N) fixation, recycling and export. Desert dust deposited on the ocean surface was shown to supply Trichodesmium with the scarce micronutrient iron. Spherical, millimeter‐sized colonies of Trichodesmium from different ocean basins were reported to actively accumulate dust in their cores. While dust accumulation likely helps Trichodesmium obtain nutrients, it may come at a cost. Metals released from dust may induce toxicity and the dust weight could send Trichodesmium to the ocean depth. Our experimental study with natural Red Sea colonies examined some trade‐offs of dust accumulation. Links between dust load and colony buoyancy were examined in sedimentation experiments. Toxicity thresholds for surface blooms and dust‐accumulating colonies were determined from mortality assays and dust dissolution measurements. We found that metal‐induced toxicity to Trichodesmium is unlikely at typical oceanic dust fluxes, and that dust‐containing colonies can remain buoyant. At high loads, dust weight determined the colony's sinking velocity. Our findings and concepts can be extended to additional aerosols and Trichodesmium ‐rich habitats, and may assist in assessing Trichodesmium 's distribution, ecophysiology, and contribution to C or N transport to the deep ocean. Key Points Dust collected by Trichodesmium colonies from seawater as a nutrient source may result in metal toxification and buoyancy loss At moderate dust loads, colonies kept their buoyancy, but above 400 ng, sinking velocities increased linearly with dust loads Desert dust induced Trichodesmium mortality through toxic metal release, yet the lethal dose far exceeded oceanic dust concentrations

    Sizing mudsnails: Applying superpixels to scale growth detection under ocean warming (2024)
    Wiley
    Details
    Publication Date: 2024-06-11
    Description: 1. The expansion of scientific image data holds great promise to quantify individuals, size distributions and traits. Computer vision tools are especially powerful to automate data mining of images and thus have been applied widely across studies in aquatic and terrestrial ecology. Yet marine benthic communities, especially infauna, remain understudied despite their dominance of marine biomass, biodiversity and playing critical roles in ecosystem functioning. 2. Here, we disaggregated infauna from sediment cores taken throughout the spring transition (April-June) from a near-natural mesocosm setup under experimental warming (Ambient, +1.5 degrees C, +3.0 degrees C). Numerically abundant mudsnails were imaged in batches under stereomicroscopy, from which we automatically counted and sized individuals using a superpixel-based segmentation algorithm. Our segmentation approach was based on clustering superpixels, which naturally partition images by low-level properties (e.g., colour, shape and edges) and allow instance-based segmentation to extract all individuals from each image. 3. We demonstrate high accuracy and precision for counting and sizing individuals, through a procedure that is robust to the number of individuals per image (5-65) and to size ranges spanning an order of magnitude (〈750 mu m to 7.4 mm). The segmentation routine provided at least a fivefold increase in efficiency compared with manual measurements. Scaling this approach to a larger dataset tallied 〉40k individuals and revealed overall growth in response to springtime warming. 4. We illustrate that image processing and segmentation workflows can be built upon existing open-access R packages, underlining the potential for wider adoption of computer vision tools among ecologists. The image-based approach also generated reproducible data products that, alongside our scripts, we have made freely available. This work reinforces the need for next-generation monitoring of benthic communities, especially infauna, which can display differential responses to average warming.

    Biological invasions are a population‐level rather than a species‐level phenomenon (2024)
    Wiley
    Details
    Publication Date: 2024-06-11
    Description: Biological invasions pose a rapidly expanding threat to the persistence, functioning and service provisioning of ecosystems globally, and to socio-economic interests. The stages of successful invasions are driven by the same mechanism that underlies adaptive changes across species in general-via natural selection on intraspecific variation in traits that influence survival and reproductive performance (i.e., fitness). Surprisingly, however, the rapid progress in the field of invasion science has resulted in a predominance of species-level approaches (such as deny lists), often irrespective of natural selection theory, local adaptation and other population-level processes that govern successful invasions. To address these issues, we analyse non-native species dynamics at the population level by employing a database of European freshwater macroinvertebrate time series, to investigate spreading speed, abundance dynamics and impact assessments among populations. Our findings reveal substantial variability in spreading speed and abundance trends within and between macroinvertebrate species across biogeographic regions, indicating that levels of invasiveness and impact differ markedly. Discrepancies and inconsistencies among species-level risk screenings and real population-level data were also identified, highlighting the inherent challenges in accurately assessing population-level effects through species-level assessments. In recognition of the importance of population-level assessments, we urge a shift in invasive species management frameworks, which should account for the dynamics of different populations and their environmental context. Adopting an adaptive, region-specific and population-focused approach is imperative, considering the diverse ecological contexts and varying degrees of susceptibility. Such an approach could improve and refine risk assessments while promoting mechanistic understandings of risks and impacts, thereby enabling the development of more effective conservation and management strategies. Biological invasions increasingly threaten global ecosystems and socio-economic interests, advancing through mechanisms like natural selection that enhance survival and reproductive traits. Our study focuses on population-level analyses of non-native European freshwater macroinvertebrates to better understand their spread and impact. We found significant variability in invasion dynamics across populations and regions, suggesting that current species-level risk assessments may overlook crucial population-specific factors.image

    Inverting Geodetic Strain Rates for Slip Deficit Rate in Complex Deforming Zones: An Application to the New Zealand Plate Boundary (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-05-17
    Description: The potential for future earthquakes on faults is often inferred from inversions of geodetically derived surface velocities for locking on faults using kinematic models such as block models. This can be challenging in complex deforming zones with many closely spaced faults or where deformation is not readily described with block motions. Furthermore, surface strain rates are more directly related to coupling on faults than surface velocities. We present a methodology for estimating slip deficit rate directly from strain rate and apply it to New Zealand for the purpose of incorporating geodetic data in the 2022 revision of the New Zealand National Seismic Hazard Model. The strain rate inversions imply slightly higher slip deficit rates than the preferred geologic slip rates on sections of the major strike‐slip systems including the Alpine Fault, the Marlborough Fault System and the northern part of the North Island Fault System. Slip deficit rates are significantly lower than even the lowest geologic estimates on some strike‐slip faults in the southern North Island Fault System near Wellington. Over the entire plate boundary, geodetic slip deficit rates are systematically higher than geologic slip rates for faults slipping less than one mm/yr but lower on average for faults with slip rates between about 5 and 25 mm/yr. We show that 70%–80% of the total strain rate field can be attributed to elastic strain due to fault coupling. The remaining 20%–30% shows systematic spatial patterns of strain rate style that is often consistent with local geologic style of faulting. Plain Language Summary The potential for future earthquakes on faults is often inferred from velocities of the ground surface derived from satellite geodesy, but this approach can be challenging in complex deforming zones with many closely spaced faults. We present a new methodology for estimating the rate at which energy is accumulating on faults using measurements of surface strain rates. The method is applied to New Zealand for the purpose of incorporating geodetic data in the 2022 revision of the New Zealand National Seismic Hazard Model. We show that 70%–80% of the total deformation field can be attributed to energy accumulation on known active faults while the source of the remaining 20%–30% remains unknown. Along some of the major faults in New Zealand we find some important differences in rates of energy accumulation from what is expected from geologic data. Estimated rates are significantly lower than even the lowest geologic estimates on some faults in the fault system near highly‐populated Wellington. Key Points We develop a method to invert geodetically derived strain rates for slip deficit rates on faults We find small but systematic differences between slip deficit rates and geologic slip rates About 70%–80% of the surface strain can be attributed to elastic strain due to coupling on faults

    Emerging Influence of Enhanced Greenland Melting on Boundary Currents and Deep Convection Regimes in the Labrador and Irminger Seas (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-05-21
    Description: Freshwater input from Greenland ice sheet melt has been increasing in the past decades from warming temperatures. To identify the impacts from enhanced meltwater input into the subpolar North Atlantic from 1997 to 2021, we use output from two nearly identical simulations in the eddy-rich model VIKING20X (1/20°) only differing in the freshwater input from Greenland: one with realistic interannually varying runoff increasing in the early 2000s and the other with climatologically (1961–2000) continued runoff. The majority of the additional freshwater remains within the boundary current enhancing the density gradient toward the warm and salty interior waters yielding increased current velocities. The accelerated boundary current shows a tendency to enhanced, upstream shifted eddy shedding into the Labrador Sea interior. Further, the experiments allow to attribute higher stratification and shallower mixed layers southwest of Greenland and deeper mixed layers in the Irminger Sea, particularly in 2015–2018, to the runoff increase in the early 2000s. Key Points The West Greenland Current (WGC) freshens and cools with the observed recent increase in meltwater runoff from Greenland The density gradient across the boundary current intensifies, strengthening the WGC and increasing local eddy formation Enhanced meltwater runoff contributed to an eastward shift in deep convection towards the Irminger Sea (2015–2018) Plain Language Summary Global warming has accelerated the melting of the Greenland ice sheet over the past few decades resulting in enhanced freshwater input into the North Atlantic. The additional freshwater can potentially inhibit deep water formation and have future implications on ocean circulation. To determine the influence from Greenland melt, we compare two high-resolution model experiments all with the same forcing but differing input of Greenland freshwater fluxes from 1997 to 2021. We find that in the experiment with realistically increasing Greenland meltwater, the water becomes fresher and cooler along the continental shelf and boundary of the subpolar gyre. The density difference between the shelf and interior increases with more freshwater, resulting in faster West Greenland Current speeds and enhanced eddy formation. Deeper mixed layers are found in the eastern Irminger Sea, particularly in 2015–2018. From 2009 to 2013, there were shallower mixed layers in the Labrador Sea where less Greenland meltwater was mixed downwards and spread eastward, causing mixed layers to deepen in the Irminger Sea.

    Low‐Frequency Earthquakes Downdip of Deep Slow Slip Beneath the North Island of New Zealand (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-05-21
    Description: We report the first catalog of low‐frequency earthquakes in the Hikurangi subduction zone, located beneath the Kaimanawa Range of the North Island at 50 km depth, downdip of regularly recurring (every 4–5 years) deep M7 slow slip events. To systematically detect low‐frequency earthquakes within the regional continuous seismic data, we utilized a matched‐filter approach with template waveforms derived from previous observations of tectonic tremor. We built our catalog of 36 low‐frequency earthquake sources, that produced almost 21,000 events over more than a decade, with two matched‐filter search iterations. In each iteration, the detections were gathered into families and their coherent waveforms processed and stacked to extract high‐quality waveforms, allowing us to pick seismic phase arrivals to locate the low‐frequency earthquakes. We highlight three characteristic features to validate that our detected events are indeed low‐frequency earthquakes: the eponymous deficit of high frequencies in their seismic waveforms, the episodic swarms of activity that define their activity through time, and their location at the plate boundary with a double‐couple source mechanism and geometry consistent with the subduction interface. Considering the observed low‐frequency earthquakes' relationship to neighboring slow slip, we observe the event swarms to occur much more frequently than the M7 slow slip events located just updip. Similar to other deep low‐frequency earthquakes in other subduction zones, we suggest that this characteristic clustering in time is driven by more frequent, smaller slow slip events that are not clearly observable at the surface. Plain Language Summary Slow slip is episodic fault slip that lasts days, weeks or months, rather than the rapid ruptures of regular earthquakes. Geodetic observations of the surface displacement produced by slow slip suggest that their timing and location influence the seismic cycle of nearby faults and may even trigger large earthquakes. Although slow slip does not produce seismic radiation itself, slow slip is often accompanied by tiny repetitive seismic signals. These tiny seismic events, called low‐frequency earthquakes, can act as a powerful indicator of when and where slow slip is happening. In this study, we develop a new approach to detect low‐frequency earthquakes within continuous seismic waveforms, revealing the first observations of low‐frequency earthquakes in the Hikurangi subduction zone beneath the North Island of New Zealand. Our catalog of low‐frequency earthquakes suggests a complex pattern of slow fault slip at depth, with more frequent activity than geodetic data alone would suggest. The observed low‐frequency earthquake activity in the Hikurangi subduction zone thus represents a unique opportunity to study the slip history at depth beneath the North Island of New Zealand. Key Points 36 low‐frequency earthquake sources are extracted from continuous waveforms through template matching, deblurring, and unsupervised learning Low‐frequency earthquake sources locate close to the plate boundary with source mechanisms consistent with the subduction interface Detected low‐frequency earthquakes are likely triggered by small, frequent, and deep slow slip not geodetically observable at the surface

    Accuracy of Ocean CO 2 Uptake Estimates at a Risk by a Reduction in the Data Collection (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-05-22
    Description: Observation‐based quantification of ocean carbon dioxide (CO 2 ) uptake relies on synthesis data sets such as the Surface Ocean CO 2 ATlas (SOCAT). However, the data collection effort has dramatically declined and the number of annual data sets in SOCATv2023 decreased by ∼35% from 2017 to 2021. This decline has led to a 65% increase (from 0.15 to 0.25 Pg C yr −1 ) in the standard deviation of seven SOCAT‐based air‐sea CO 2 flux estimates. Reducing the availability of the annual data to that in the year 2000 creates substantial bias (50%) in the long‐term flux trend. The annual mean CO 2 flux is insensitive to the seasonal skew of the SOCAT data and to the addition of the lower accuracy data set available in SOCAT. Our study highlights the need for sustained data collection and synthesis, to inform the Global Carbon Budget assessment, the UN‐led climate negotiations, and measurement, reporting, and verification of ocean‐based CO 2 removal projects. Plain Language Summary The Surface Ocean CO 2 ATlas (SOCAT) data set plays a crucial role in estimating the ocean carbon sink component of the Global Carbon Budget. However, the number of data sets available in SOCAT each year has drastically decreased since 2017. This study shows that the uncertainty in the data‐based ocean CO 2 flux estimate has increased by 65% due to this decline in data availability. The estimated fluxes, especially the long‐term flux trend, are remarkably affected by the data availability in SOCAT, reducing the reliability of ocean CO 2 uptake estimates in years and regions with sparse observations. Key Points Lower surface ocean f CO 2 data availability leads to higher uncertainty in data‐based estimates of ocean CO 2 uptake The long‐term trend in the ocean CO 2 flux increases by 1.5 times for subsequent years if the data availability is reduced to that in 2000 The annual mean CO 2 flux is not sensitive to the seasonal skew in the data and to the addition of low accuracy data

    Combining mesocosms with models reveals effects of global warming and ocean acidification on a temperate marine ecosystem (2024)
    ESA | Wiley
    Details
    Publication Date: 2024-05-22
    Description: Ocean warming and species exploitation have already caused large‐scale reorganization of biological communities across the world. Accurate projections of future biodiversity change require a comprehensive understanding of how entire communities respond to global change. We combined a time‐dynamic integrated food web modeling approach (Ecosim) with previous data from community‐level mesocosm experiments to determine the independent and combined effects of ocean warming, ocean acidification and fisheries exploitation on a well‐managed temperate coastal ecosystem. The mesocosm parameters enabled important physiological and behavioral responses to climate stressors to be projected for trophic levels ranging from primary producers to top predators, including sharks. Through model simulations, we show that under sustainable rates of fisheries exploitation, near‐future warming or ocean acidification in isolation could benefit species biomass at higher trophic levels (e.g., mammals, birds, and demersal finfish) in their current climate ranges, with the exception of small pelagic fishes. However, under warming and acidification combined, biomass increases at higher trophic levels will be lower or absent, while in the longer term reduced productivity of prey species is unlikely to support the increased biomass at the top of the food web. We also show that increases in exploitation will suppress any positive effects of human‐driven climate change, causing individual species biomass to decrease at higher trophic levels. Nevertheless, total future potential biomass of some fisheries species in temperate areas might remain high, particularly under acidification, because unharvested opportunistic species will likely benefit from decreased competition and show an increase in biomass. Ecological indicators of species composition such as the Shannon diversity index decline under all climate change scenarios, suggesting a trade‐off between biomass gain and functional diversity. By coupling parameters from multilevel mesocosm food web experiments with dynamic food web models, we were able to simulate the generative mechanisms that drive complex responses of temperate marine ecosystems to global change. This approach, which blends theory with experimental data, provides new prospects for forecasting climate‐driven biodiversity change and its effects on ecosystem processes.

    Using NIW Observations to Assess Mixed Layer Parameterizations: A Case Study in the Tropical Atlantic (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-05-30
    Description: Tropical sea surface temperature (SST) biases can cause atmospheric biases on global scales, hence SST needs to be represented well in climate models. A major source of uncertainties is the representation of turbulent mixing in the oceanic boundary layer, or mixed layer (ML). In the present study we focus on near-inertial wave (NIW) induced mixing. The performance of two mixing schemes, Turbulent Kinetic Energy and K-profile parameterization (KPP), is assessed at two sites (11.5°N, 23°W and 15°N, 38°W) in the tropical Atlantic. At 11.5°N, turbulence observations (eddy diffusivities, shear and stratification) are available for comparison. We find that the schemes differ in their representation of NIWs, but both under-represent the observed enhanced diffusivities below the observed ML. However, we find that the models do mix below the ML at 15°N when a storm passes nearby. The near-inertial oscillations remain below the ML for the following 10 days. Near-inertial kinetic energy (NIKE) biases in the models are not directly correlated with the wind speed, the MLD biases, or the stratification at the ML base. Instead, NIKE biases are sensitive to the vertical mixing scheme parameterization. NIKE biases are lowest when the KPP scheme is used. Key Points: - Observations of inertial oscillations are used to evaluate the performance of two vertical mixing schemes in two high-resolution models - Both the K-profile parameterization and the Turbulent Kinetic Energy closure underestimate the NIW-induced mixing - Near-inertial kinetic energy biases are sensitive to the vertical mixing parameterization

    Influence of GIA Uncertainty on Climate Model Evaluation With GRACE/GRACE‐FO Satellite Gravimetry Data (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-05-28
    Description: Global coupled climate models are in continuous need for evaluation against independent observations to reveal systematic model deficits and uncertainties. Changes in terrestrial water storage (TWS) as measured by satellite gravimetry missions GRACE and GRACE-FO provide valuable information on wetting and drying trends over the continents. Challenges arising from a comparison of observed and modelled water storage trends are related to gravity observations including non-water related variations such as, for example, glacial isostatic adjustment (GIA). Therefore, correcting secular changes in the Earth's gravity field caused by ongoing GIA is important for the monitoring of long-term changes in terrestrial water from GRACE in particular in former ice-covered regions. By utilizing a new ensemble of 56 individual realizations of GIA signals based on perturbations of mantle viscosities and ice history, we find that many of those alternative GIA corrections change the direction of GRACE-derived water storage trends, for example, from gaining mass into drying conditions, in particular in Eastern Canada. The change in the sign of the TWS trends subsequently impacts the conclusions drawn from using GRACE as observational basis for the evaluation of climate models as it influences the dis-/agreement between observed and modelled wetting/drying trends. A modified GIA correction, a combined GRACE/GRACE-FO data record extending over two decades, and a new generation of climate model experiments leads to substantially larger continental areas where wetting/drying trends currently observed by satellite missions coincide with long-term predictions obtained from climate model experiments.

    Geomorphology and Age Constraints of Seamounts in the Cabo Verde Archipelago, and Their Relationship to Island Ages and Geodynamic Evolution (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-05-28
    Description: The Cabo Verde Archipelago is related to a mantle plume located close to the rotational pole of the African Plate. It consists of islands and seamounts arranged in a horseshoe‐shaped pattern open to the west, thus forming two volcanic chains, each with a weak east‐west age progression. High‐resolution swath bathymetry of 12 Cabo Verde seamounts is used here to assign each seamount to its pre‐shield, shield or post‐shield evolutionary stage, respectively. The eastern seamounts exhibit degraded and partially eroded morphologies, and are mainly in their post‐shield stage. A new 40 Ar‐ 39 Ar date for Senghor Seamount at 14.872 ± 0.027 Ma supports old ages for the eastern seamounts. The western seamounts generally exhibit younger volcanic‐edifice‐construction morphologies, showing fresh effusive and explosive volcanics, including rarely observed deep‐water explosive volcanism in the Charles Darwin Volcanic Field. Furthermore, the two previously unknown seamounts Sodade and Tavares in the westernmost termini of both volcanic chains exhibit pristine volcanic morphologies, in agreement with present‐day volcanism and seismic activity recorded from the western seamounts. The islands and seamounts rest on three submarine platforms to the east, northwest and southwest, respectively. Taken together, the seamount and island data suggest a shift in igneous activity from the eastern to the other platforms at about 8–6 Ma. However, the complex evolution pattern for both volcanic chains includes the simultaneous occurrence of pre‐shield or shield edifices at any time, followed by erosional and rejuvenation stages. The new seamount data still demonstrate ongoing westward submarine‐growth in both volcanic chains. Plain Language Summary The Cabo Verde volcanic islands and seamounts are located in the central Atlantic Ocean, ∼570 km off the west coast of Africa. They form a horseshoe‐shaped archipelago with two volcanic chains, which were formed by the African plate moving very slowly over a mantle hotspot (the Cabo Verde Plume). Both the northern and southern volcanic chains show weak east‐to‐west age progressions from ∼26 million years to the present day. This study uses underwater topographic data and observations/rock sampling via remotely operated vehicles from 12 submarine volcanic seamounts, including two previously unknown seamounts, collected during four research cruises in the Cabo Verde Archipelago. Geomorphology is used to classify each seamount as being in its pre‐shield, shield or post‐shield evolutionary stage, respectively. Cabo Verde islands and seamounts rest on three submarine morphological platforms, reflecting westward jumps of the main igneous activity, and also confirming the westward migration of the Cabo Verde hotspot beneath both volcanic chains. Key Points We present bathymetrical maps of 12, in part previously uncharted Cabo Verde seamounts Geomorphology reflects various evolutionary seamount stages and relative ages. Four older seamounts indicate late Quaternary sea level lowstands Islands and seamounts rest on three morphological platforms, indicating westward jumps of the main igneous activity

    “Seeing” Beneath the Clouds — Machine-Learning-Based Reconstruction of North African Dust Plumes (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-05-28
    Description: Mineral dust is one of the most abundant atmospheric aerosol species and has various far-reaching effects on the climate system and adverse impacts on air quality. Satellite observations can provide spatio-temporal information on dust emission and transport pathways. However, satellite observations of dust plumes are frequently obscured by clouds. We use a method based on established, machine-learning-based image in-painting techniques to restore the spatial extent of dust plumes for the first time. We train an artificial neural net (ANN) on modern reanalysis data paired with satellite-derived cloud masks. The trained ANN is applied to cloud-masked, gray-scaled images, which were derived from false color images indicating elevated dust plumes in bright magenta. The images were obtained from the Spinning Enhanced Visible and Infrared Imager instrument onboard the Meteosat Second Generation satellite. We find up to 15% of summertime observations in West Africa and 10% of summertime observations in Nubia by satellite images miss dust plumes due to cloud cover. We use the new dust-plume data to demonstrate a novel approach for validating spatial patterns of the operational forecasts provided by the World Meteorological Organization Dust Regional Center in Barcelona. The comparison elucidates often similar dust plume patterns in the forecasts and the satellite-based reconstruction, but once trained, the reconstruction is computationally inexpensive. Our proposed reconstruction provides a new opportunity for validating dust aerosol transport in numerical weather models and Earth system models. It can be adapted to other aerosol species and trace gases. Key Points: - We present the first fast reconstruction of cloud-obscured Saharan dust plumes through novel machine learning applied to satellite images - The reconstruction algorithm utilizes partial convolutions to restore cloud-induced gaps in gray-scaled Meteosat Second Generation-Spinning Enhanced Visible and Infrared Imager Dust RGB images - World Meteorological Organization dust forecasts for North Africa mostly agree with the satellite-based reconstruction of the dust plume extent

    Non‐selective microbiota reduction after the elicitation of a seaweed's immune response (2024)
    Wiley
    Details
    Publication Date: 2024-06-05
    Description: Pattern-triggered immunity (PTI) is an integral part of the innate immune system of many eukaryotic hosts, assisting in the defence against pathogen invasions. In plants and animals, PTI exerts a selective pressure on the microbiota that can alter community composition. However, the effect of PTI on the microbiota for non-model hosts, including seaweeds, remains unknown. Using quantitative polymerase chain reaction complemented with 16S rRNA gene and transcript amplicon sequencing, this study profiled the impact that PTI of the red seaweed Gracilaria gracilis has on its microbiota. PTI elicitation with agar oligosaccharides resulted in a significant reduction in the number of bacteria (by 〉75% within 72 h after treatment). However, the PTI elicitation did not cause any significant difference in the community diversity or structure. These findings demonstrated that PTI can be non-selective, and this might help to maintain a stable microbiota by uniformly reducing bacterial loads.

    On the Mechanisms Driving Latent Heat Flux Variations in the Northwest Tropical Atlantic (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-06-06
    Description: The Northwest Tropical Atlantic (NWTA) is a region of complex surface ocean circulation. The most prominent feature is the North Brazil Current (NBC) and its retroflection at 8°N, which leads to the formation of numerous mesoscale eddies known as NBC rings. The NWTA also receives the outflow of the Amazon River, generating freshwater plumes that can extend up to 100,000 km2. We show that these two processes influence the spatial variability of the region's surface latent heat flux (LHF). On the one hand, the presence of surface freshwater modifies the vertical stratification of the ocean, the mixed layer heat budget, and thus the air-sea heat exchanges. On the other hand, NBC rings create a highly heterogeneous mesoscale sea surface temperature (SST) field that directly influences the near-surface atmospheric circulation. These effects are illustrated by observations from the ElUcidating the RolE of Cloud-Circulation Coupling in ClimAte - Ocean Atmosphere (EUREC4A-OA) and Atlantic Tradewind Ocean-Atmosphere Interaction Campaign (ATOMIC) experiments, satellite and reanalysis data. We decompose the LHF budget into several terms controlled by different atmospheric and oceanic processes to identify the mechanisms leading to LHF changes. We find LHF variations of up to 160 W m2, of which 100 W m2 are associated with wind speed changes and 40 W m2 with SST variations. Surface currents or heat release associated with stratification changes remain as second-order contributions with LHF variations of less than 10 W m2 each. This study highlights the importance of considering these three components to properly characterize LHF variability at different spatial scales, although it is limited by the scarcity of collocated observations. Key Points: - Latent heat flux (LHF) presents strong spatial variations in the northwest tropical Atlantic (NWTA), which has a complex ocean circulation - Surface winds and sea surface temperature are the major drivers of LHF changes. The Amazon plume remains as a second-order contributor - It is necessary to distinguish between spatial scales (mesoscale and below vs. large-scale) when assessing the ocean's influence on LHF

    Impact of persistently high sea surface temperatures on the rhizobiomes of Zostera marina in a Baltic Sea benthocosms (2024)
    Wiley
    Details
    Publication Date: 2024-06-07
    Description: Persistently high marine temperatures are escalating and threating marine biodiversity. The Baltic Sea, warming faster than other seas, is a good model to study the impact of increasing sea surface temperatures. Zostera marina, a key player in the Baltic ecosystem, faces susceptibility to disturbances, especially under chronic high temperatures. Despite the increasing number of studies on the impact of global warming on seagrasses, little attention has been paid to the role of the holobiont. Using an outdoor benthocosm to replicate near-natural conditions, this study explores the repercussions of persistent warming on the microbiome of Z. marina and its implications for holobiont function. Results show that both seasonal warming and chronic warming, impact Z. marina roots and sediment microbiome. Compared with roots, sediments demonstrate higher diversity and stability throughout the study, but temperature effects manifest earlier in both compartments, possibly linked to premature Z. marina die-offs under chronic warming. Shifts in microbial composition, such as an increase in organic matter-degrading and sulfur-related bacteria, accompany chronic warming. A higher ratio of sulfate-reducing bacteria compared to sulfide oxidizers was found in the warming treatment which may result in the collapse of the seagrasses, due to toxic levels of sulfide. Differentiating predicted pathways for warmest temperatures were related to sulfur and nitrogen cycles, suggest an increase of the microbial metabolism, and possible seagrass protection strategies through the production of isoprene. These structural and compositional variations in the associated microbiome offer early insights into the ecological status of seagrasses. Certain taxa/genes/pathways may serve as markers for specific stresses. Monitoring programs should integrate this aspect to identify early indicators of seagrass health. Understanding microbiome changes under stress is crucial for the use of potential probiotic taxa to mitigate climate change effects. Broader-scale examination of seagrass–microorganism interactions is needed to leverage knowledge on host–microbe interactions in seagrasses.

    A Comprehensive Assessment of Carbon Dioxide Removal Options for Germany (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-06-07
    Description: To reach their net-zero targets, countries will have to compensate hard-to-abate CO2 emissions through carbon dioxide removal (CDR). Yet, current assessments rarely include socio-cultural or institutional aspects or fail to contextualize CDR options for implementation. Here we present a context-specific feasibility assessment of CDR options for the example of Germany. We assess 14 CDR options, including three chemical carbon capture options, six options for bioenergy combined with carbon capture and storage (BECCS), and five options that aim to increase ecosystem carbon uptake. The assessment addresses technological, economic, environmental, institutional, social-cultural and systemic considerations using a traffic-light system to evaluate implementation opportunities and hurdles. We find that in Germany CDR options like cover crops or seagrass restoration currently face comparably low implementation hurdles in terms of technological, economic, or environmental feasibility and low institutional or social opposition but show comparably small CO2 removal potentials. In contrast, some BECCS options that show high CDR potentials face significant techno-economic, societal and institutional hurdles when it comes to the geological storage of CO2. While a combination of CDR options is likely required to meet the net-zero target in Germany, the current climate protection law includes a limited set of options. Our analysis aims to provide comprehensive information on CDR hurdles and possibilities for Germany for use in further research on CDR options, climate, and energy scenario development, as well as an effective decision support basis for various actors. Key Points: - More context-specific assessments of carbon dioxide removal (CDR) options are needed to guide national net-zero decision making - Ecosystem-based CDR options with comparably low implementation hurdles in Germany show relatively small CO2 removal potentials - High CDR potential options in Germany face high institutional, technological and societal hurdles linked in many ways to geological storage

    Giant eggs in a deep‐sea squid (2024)
    Wiley
    Details
    Publication Date: 2024-06-12
    Description: The deep-sea water column below 200 m is a vast three-dimensional habitat with an enormous but largely unexplored biodiversity (Robison, 2009). Cephalopod mollusks are abundant in the deep sea and are important prey for many kinds of predators. Still, most deep-sea cephalopods have never been observed alive in their natural habitat and their reproductive biology remains poorly documented. In March of 2015, at a depth of 2566 m, we observed a female squid of an undescribed species but likely belonging to the Gonatidae, carrying few but exceptionally large eggs in her arms. This raises questions as to how these and other related animals reproduce in the deep sea, an environment that is generally characterized by darkness, low temperature, reduced oxygen, limited food availability, and low population densities. The authors were conducting dives with deep-sea robots (remotely operated vehicles or ROVs) equipped with cameras in the deep basins of the Gulf of California, to investigate how deep-sea fauna are distributed in relation to the extensive low-oxygen zones in the region (Gilly et al., 2013). The squid (Individual 1, Table 1) we observed with an ROV at 2566 m in the Gulf of California in 2015 was carrying 30–40 large eggs (average maximum diameter 11.2 mm, n = 5; measured eggs were 11.4, 10.4, 11.5, 11.7 and 11 mm maximum diameter) embedded in a small external egg sheet that did not extend beyond the arm tips. The size of the eggs was similar to those of two squid (Individuals 2 and 3, Table 1) that were observed close to the seafloor during earlier expeditions in the same region.

    Global Climatology of Low‐Level‐Jets: Occurrence, Characteristics, and Meteorological Drivers (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-06-12
    Description: Low-level jets (LLJs), vertical profiles with a wind speed maxima in the lowest hundred meters of the troposphere, have multiple impacts in the Earth system, but a global present-day climatology based on contemporary data does not exist. We use the spatially and temporally complete data set from ERA5 reanalysis to compile a global climatology of LLJs for studying the formation mechanisms, characteristics, and trends during the period of 1992–2021. In the global mean, LLJs are detected 21% of the time with more cases over land (32%) than over the ocean (15%). We classified the LLJs into three categories: non-polar land (LLLJ), polar land (PLLJ), and coastal (CLLJ) LLJs. For LLLJ, the averaged frequency of occurrence is 20% and 75% of them are associated with a near-surface temperature inversion as a prerequisite for an inertial oscillation. PLLJs are also associated with a temperature inversion and occur even more frequently with 59% of the time. These are also the lowest and the strongest LLJs among the three categories. CLLJs are particularly frequent in some marine hotspots, situated along the west coast of continents, with neutral to unstable stratification close to the surfaces and a stably stratified layer aloft. We found distinct regional trends in both the frequency and intensity of LLJs over the past decades, which can have implications for the emission and transport of aerosols, and the transport of atmospheric moisture. Future studies could address changes in LLJs and the associated implications in more detail, based on the here released ERA5-based LLJ data. Key Points: - First global comprehensive low-level jet (LLJ) climatology using ERA5 - Polar LLJs are the strongest and most frequent among the detected types - Distinct past trends in regional LLJ frequency and intensity

    Integrative taxonomy of new neomphaloidean gastropods from deep-sea hot vents of the southwestern Pacific (2024)
    Oxford University Press
    Details
    Publication Date: 2024-06-13
    Description: Neomphaloidean gastropods are endemic to chemosynthesis-based ecosystems ranging from hot vents to organic falls, and their diversity and evolutionary history remain poorly understood. In the southwestern Pacific, deep-sea hydrothermal vents on back-arc basins and volcanic arcs are found in three geographically secluded regions: a western region around Manus Basin, an eastern region around North Fiji and Lau Basins, and the intermediate Woodlark Basin where active venting was confirmed only recently, on the 2019 R/V L’Atalante CHUBACARC expedition. Although various lineages of neomphaloidean snails have been detected, typically restricted to one of the three regions, some of these have remained without names. Here, we use integrative taxonomy to describe three of these species: the neomphalid Symmetromphalus mithril sp. nov. from Woodlark Basin and the peltospirids Symmetriapelta becki sp. nov. from the eastern region and Symmetriapelta radiata sp. nov. from Woodlark Basin. A combination of shell sculpture and radular characters allow the morphological separation of these new species from their described congeners. A molecular phylogeny reconstructed from 570 bp of the mitochondrial cytochrome c oxidase subunit I gene confirmed the placement of the three new species in their respective genera and the superfamily Neomphaloidea. The finding of these new gastropods, particularly the ones from the Woodlark Basin, provides insights and implications on the historical role of Woodlark as a dispersing centre, in addition to highlighting the uniqueness of the Woodlark faunal community.

    Impact of green and blue‐green light on the growth, pigment concentration, and fatty acid unsaturation in the microalga Monoraphidium braunii (2024)
    Wiley
    Details
    Publication Date: 2024-06-14
    Description: The spectral composition of light is an important factor for the metabolism of photosynthetic organisms. Several blue light-regulated metabolic processes have already been identified in the industrially relevant microalga Monoraphidium braunii. However, little is known about the spectral impact on this species' growth, fatty acid (FA), and pigment composition. In this study, M. braunii was cultivated under different light spectra (white light: 400–700 nm, blue light: 400–550 nm, green light: 450–600 nm, and red light: 580–700 nm) at 25°C for 96 h. The growth was monitored daily. Additionally, the FA composition, and pigment concentration was analyzed after 96 h. The highest biomass production was observed upon white light and red light irradiation. However, green light also led to comparably high biomass production, fueling the scientific debate about the contribution of weakly absorbed light wavelengths to microalgal biomass production. All light spectra (white, blue, and green) that comprised blue-green light (450–550 nm) led to a higher degree of FA unsaturation and a greater concentration of all identified pigments than red light. These results further contribute to the growing understanding that blue-green light is an essential trigger for maximized pigment concentration and FA unsaturation in green microalgae.

    UXO and environmental risk factors impacting EOD operations in German waters** (2024)
    Wiley
    Details
    Publication Date: 2024-06-14
    Description: This article presents risk factors that are associated with the handling of unexploded ordnance (UXO) during explosive ordnance disposal (EOD) operations in German waters. The construction of offshore wind parks and the German immediate action program are expected to increase the number of EOD operations. Existing literature and guidelines do not offer a structured and reproducible framework for assessing EOD risk. To fill this gap, a network of EOD risk factors was developed by means of a literature review and validation via expert consultation. The study was scoped to “personnel and equipment at the EOD location” as the risk receptor and “undesired detonation” as the undesired event under investigation. Factors are subdivided into UXO factors that depend on the object that should be handled and factors that describe the object's surrounding environment. While the former can be researched by an EOD expert, the latter must be measured on site or acquired from a model. Each of these factors contributes to risk, some directly and others indirectly via other factors. The complexity of the resulting network, with its 33 factors, demonstrates the need for a reliable and reproducible model to quantify EOD risk. Its purpose is not to replace EOD experts but to aid them in their decision‐making process. Such a tool can provide valuable support for the high‐cost and high‐risk EOD operations.

    Suboptimal environmental conditions prolong phage epidemics in bacterial populations (2024)
    Wiley
    Details
    Publication Date: 2024-06-14
    Description: Infections by filamentous phages, which are usually nonlethal to the bacterial cells, influence bacterial fitness in various ways. While phage-encoded accessory genes, for example virulence genes, can be highly beneficial, the production of viral particles is energetically costly and often reduces bacterial growth. Consequently, if costs outweigh benefits, bacteria evolve resistance, which can shorten phage epidemics. Abiotic conditions are known to influence the net-fitness effect for infected bacteria. Their impact on the dynamics and trajectories of host resistance evolution, however, remains yet unknown. To address this, we experimentally evolved the bacterium Vibrio alginolyticus in the presence of a filamentous phage at three different salinity levels, that is (1) ambient, (2) 50% reduction and (3) fluctuations between reduced and ambient. In all three salinities, bacteria rapidly acquired resistance through super infection exclusion (SIE), whereby phage-infected cells acquired immunity at the cost of reduced growth. Over time, SIE was gradually replaced by evolutionary fitter surface receptor mutants (SRM). This replacement was significantly faster at ambient and fluctuating conditions compared with the low saline environment. Our experimentally parameterized mathematical model explains that suboptimal environmental conditions, in which bacterial growth is slower, slow down phage resistance evolution ultimately prolonging phage epidemics. Our results may explain the high prevalence of filamentous phages in natural environments where bacteria are frequently exposed to suboptimal conditions and constantly shifting selections regimes. Thus, our future ocean may favour the emergence of phage-born pathogenic bacteria and impose a greater risk for disease outbreaks, impacting not only marine animals but also humans.

    Comparing environmental impacts of deep‐seabed and land‐based mining: A defensible framework (2024)
    Wiley
    Details
    Publication Date: 2024-06-17
    Description: The crises of climate change and biodiversity loss are interlinked and must be addressed jointly. A proposed solution for reducing reliance on fossil fuels, and thus mitigating climate change, is the transition from conventional combustion-engine to electric vehicles. This transition currently requires additional mineral resources, such as nickel and cobalt used in car batteries, presently obtained from land-based mines. Most options to meet this demand are associated with some biodiversity loss. One proposal is to mine the deep seabed, a vast, relatively pristine and mostly unexplored region of our planet. Few comparisons of environmental impacts of solely expanding land-based mining versus extending mining to the deep seabed for the additional resources exist and for biodiversity only qualitative. Here, we present a framework that facilitates a holistic comparison of relative ecosystem impacts by mining, using empirical data from relevant environmental metrics. This framework (Environmental Impact Wheel) includes a suite of physicochemical and biological components, rather than a few selected metrics, surrogates, or proxies. It is modified from the “recovery wheel” presented in the International Standards for the Practice of Ecological Restoration to address impacts rather than recovery. The wheel includes six attributes (physical condition, community composition, structural diversity, ecosystem function, external exchanges and absence of threats). Each has 3–5 sub attributes, in turn measured with several indicators. The framework includes five steps: (1) identifying geographic scope; (2) identifying relevant spatiotemporal scales; (3) selecting relevant indicators for each sub-attribute; (4) aggregating changes in indicators to scores; and (5) generating Environmental Impact Wheels for targeted comparisons. To move forward comparisons of land-based with deep seabed mining, thresholds of the indicators that reflect the range in severity of environmental impacts are needed. Indicators should be based on clearly articulated environmental goals, with objectives and targets that are specific, measurable, achievable, relevant, and time bound.

    Observations of Barrier Layer Seasonal Variation in the Banda Sea (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-06-17
    Description: The Banda Sea is of crucial importance for the circulation of the world's oceans, as it is part of the connection between the Pacific to the Indian Ocean. One peculiarity of the upper ocean hydrography in the Banda Sea is the occurrence of barrier layers. The regionality and temporal variability of barrier layer thickness (BLT) in the Banda Sea are examined in this study utilizing in-situ observations and ocean reanalysis output. It is found that a barrier layer occurs in over 90 % of the observational data profiles, and in over 72 % of those profiles, the BLT is shallower than 10 m. Furthermore, we find a seasonal cycle in BLT with a maximum thickness of about 60 m occurring during austral autumn and winter and coinciding with the presence of low saline waters fed by the regional river discharge and rainfall from the Java Sea and Makassar Strait. In addition, we identify the existence of a quasi-permanent anticyclonic circulation cell in the Banda Sea that may support the trapping of surface freshwater by retention. The anticyclonic circulation is most likely wind-driven because it coincides with the regional Ekman pumping pattern. Modulation of the anticyclone is via seasonal variability in the wind stress curl which in turn may explain the efficiency of freshwater retention and thus the BLT. The annual mean BLT distribution in the Banda Sea shows a preferential region of thickened barrier layers around 6o-8oS and 124o-126oE and resampling the pattern of the monthly mean climatology. Key Points: - First study estimating barrier layer thickness (BLT) in the Banda Sea using comprehensive observations - A quasi-permanent barrier layer exists in the Banda Sea with seasonal variation in occurrence and thickness - The intrusion of low saline waters and anticyclonic circulation are identified as the main mechanisms for creating and modulating the local BLT

    Reconstruction of Cenozoic δ11Bsw Using A Gaussian Process (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-06-17
    Description: Key Points: - We reconstruct the temporal evolution of seawater isotope ratios of boron, strontium, lithium, and osmium over the last 65 million years - The evolution of seawater boron isotope ratio shows similarity to the evolution of strontium, lithium and osmium isotope ratios - Randomly drawn, smooth time series are provided for use in uncertainty propagation in calculation of palaeo pH The boron isotope ratio of seawater (δ11Bsw) is a parameter which must be known to reconstruct palaeo pH and CO2 from boron isotope measurements of marine carbonates. Beyond a few million years ago, δ11Bsw is likely to have been different to modern. Palaeo δ11Bsw can be estimated by simultaneously constraining the vertical gradients in foraminiferal δ11B (Δδ11B) and pH (ΔpH). A number of subtly different techniques have been used to estimate ΔpH in the past, all broadly based on assumptions about vertical gradients in oxygen, and/or carbon, or other carbonate system constraints. In this work we pull together existing data from previous studies, alongside a constraint on the rate of change of δ11Bsw from modeling. We combine this information in an overarching statistical framework called a Gaussian Process. The Gaussian Process technique allows us to bring together data and constraints on the rate of change in δ11Bsw to generate random plausible evolutions of δ11Bsw. We reconstruct δ11Bsw, and by extension palaeo pH, across the last 65Myr using this novel methodology. Reconstructed δ11Bsw is compared to other seawater isotope ratios, namely ,87/86 Sr, 187/188 Os , and δ7Li, which we also reconstruct with Gaussian Processes. Our method provides a template for incorporation of future δ11Bsw constraints, and a mechanism for propagation of uncertainty in δ11Bsw into future studies.

    Evidence for Low-Pressure Crustal Anatexis During the Northeast Atlantic Break-up (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-06-18
    Description: While basaltic volcanism is dominate during rifting and continental breakup, felsic magmatism may also comprise important components of some rift margins. During International Ocean Discovery Program (IODP) Expedition 396 on the continental margin of Norway, a graphite-garnet-cordierite bearing dacitic, pyroclastic unit was recovered within early Eocene sediments on Mimir High (Site U1570), a marginal high on the Vøring transform margin. Here, we present a comprehensive textural, mineralogical, and petrological study of the dacite in order to assess its melting origin and emplacement. The major mineral phases (garnet, cordierite, quartz, plagioclase, alkali feldspar) are hosted in a fresh rhyolitic, highly vesicular, glassy matrix, locally mingled with sediments. The xenocrystic major element chemistry of garnet and cordierite, the presence of zircon inclusions with inherited cores, and thermobarometric calculations all support a crustal metapelite origin. While most magma-rich margin models favor crustal anatexis in the lower crust, thermobarometric calculations performed here show that the dacite was produced at upper-crustal depths (〈 5 kbar) and high temperature (750–800 °C) with up to 3 wt% water content. In situ U-Pb analyses on zircon inclusions give a magmatic age of 54.6 ± 1.1 Ma, revealing the emplacement of the dacite post-dates the Paleocene-Eocene Thermal Maximum (PETM). Our results suggest that the opening of the North Atlantic was associated with a phase of low-pressure, high-temperature crustal melting at the onset of the main phase of magmatism.

    Comprehensive molecular‐isotopic characterization of archaeal lipids in the Black Sea water column and underlying sediments (2024)
    Wiley
    Details
    Publication Date: 2024-06-20
    Description: The Black Sea is a permanently anoxic, marine basin serving as model system for the deposition of organic-rich sediments in a highly stratified ocean. In such systems, archaeal lipids are widely used as paleoceanographic and biogeochemical proxies; however, the diverse planktonic and benthic sources as well as their potentially distinct diagenetic fate may complicate their application. To track the flux of archaeal lipids and to constrain their sources and turnover, we quantitatively examined the distributions and stable carbon isotopic compositions (delta 13C) of intact polar lipids (IPLs) and core lipids (CLs) from the upper oxic water column into the underlying sediments, reaching deposits from the last glacial. The distribution of IPLs responded more sensitively to the geochemical zonation than the CLs, with the latter being governed by the deposition from the chemocline. The isotopic composition of archaeal lipids indicates CLs and IPLs in the deep anoxic water column have negligible influence on the sedimentary pool. Archaeol substitutes tetraether lipids as the most abundant IPL in the deep anoxic water column and the lacustrine methanic zone. Its elevated IPL/CL ratios and negative delta 13C values indicate active methane metabolism. Sedimentary CL- and IPL-crenarchaeol were exclusively derived from the water column, as indicated by non-variable delta 13C values that are identical to those in the chemocline and by the low BIT (branched isoprenoid tetraether index). By contrast, in situ production accounts on average for 22% of the sedimentary IPL-GDGT-0 (glycerol dibiphytanyl glycerol tetraether) based on isotopic mass balance using the fermentation product lactate as an endmember for the dissolved substrate pool. Despite the structural similarity, glycosidic crenarchaeol appears to be more recalcitrant in comparison to its non-cycloalkylated counterpart GDGT-0, as indicated by its consistently higher IPL/CL ratio in sediments. The higher TEX86, CCaT, and GDGT-2/-3 values in glacial sediments could plausibly result from selective turnover of archaeal lipids and/or an archaeal ecology shift during the transition from the glacial lacustrine to the Holocene marine setting. Our in-depth molecular-isotopic examination of archaeal core and intact polar lipids provided new constraints on the sources and fate of archaeal lipids and their applicability in paleoceanographic and biogeochemical studies.

    Volcanic flank collapse, secondary sediment failure and flow-transition: multi-stage landslide emplacement offshore Montserrat, Lesser Antilles (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-06-26
    Description: Volcanic flank collapses, especially those in island settings, have generated some of the most voluminous mass transport deposits on Earth and can trigger devastating tsunamis. Reliable tsunami hazard assessments for flank collapse-driven tsunamis require an understanding of the complex emplacement processes involved. The seafloor sequence southeast of Montserrat (Lesser Antilles) is a key site for the study of volcanic flank collapse emplacement processes that span subaerial to submarine environments. Here, we present new 2D and 3D seismic data as well as MeBo drill core data from one of the most extensive mass transport deposits offshore Montserrat, which exemplifies multi-phase landslide deposition from volcanic islands. The deposits reveal emplacement in multiple stages including two blocky volcanic debris avalanches, secondary seafloor failure and a late-stage erosive density current that carved channel-like incisions into the hummocky surface of the deposit about 15 km from the source region. The highly erosive density current potentially originated from downslope-acceleration of fine-grained material that was suspended in the water column earlier during the slide. Late-stage erosive turbidity currents may be a more common process following volcanic sector collapse than has been previously recognized, exerting a potentially important control on the observed deposit morphology as well as on the runout and the overall shape of the deposit. Key Points Landslide emplacement offshore Montserrat included volcanic flank collapses, sediment incorporation, and a late-stage erosive flow Highly erosive flows are likely to be common processes during volcanic flank collapse deposition Pre-existing topography plays a major role in shaping flank collapse-associated mass transport deposits Plain Language Summary Disintegration of volcanic islands can cause very large landslides and destructive tsunamis. To assess the tsunami hazard of such events, it is crucial to understand the processes that are involved in their formation. We present new insights from seismic data and drill cores from a landslide deposit offshore Montserrat, a volcanic island in the Lesser Antilles Arc in the Caribbean. Our analysis reveals the emplacement of landslide material in several stages, including multiple volcanic flank collapses, incorporation of seafloor sediments and an erosive flow that carved channels into the top of the deposit right after its emplacement. We suggest that highly erosive flows are a common process during volcanic flank collapse deposition and that they play a significant role in the shaping of the deposit's appearance.

    Long-term culture system for deep-sea mussels Gigantidas childressi (2024)
    ASLO (Association for the Sciences of Limnology and Oceanography) | Wiley
    Details
    Publication Date: 2024-06-24
    Description: The simulation of deep-sea conditions in laboratories is technically challenging but necessary for experiments that aim at a deeper understanding of physiological mechanisms or host-symbiont interactions of deep-sea organisms. In a proof-of-concept study, we designed a recirculating system for long-term culture (〉2 yr) of deep-sea mussels Gigantidas childressi (previously Bathymodiolus childressi). Mussels were automatically (and safely) supplied with a maximum stable level of ~60 μmol L−1 methane in seawater using a novel methane–air mixing system. Experimental animals also received daily doses of live microalgae. Condition indices of cultured G. childressi remained high over the years, and low shell growth rates could be detected, too, which is indicative of positive energy budgets. Using stable isotope data, we demonstrate that G. childressi in our culture system gained energy, both, from the digestion of methane-oxidizing endosymbionts and from digesting particulate food (microalgae). Limitations of the system, as well as opportunities for future experimental approaches involving deep-sea mussels, are discussed.

    Zooplankton seasonal vertical migration in an optimality-based plankton ecosystem model (2024)
    Oxford University Press
    Details
    Publication Date: 2024-06-24
    Description: Several species from various zooplankton taxa perform seasonal vertical migrations (SVM) of typically several hundred meters between the surface layer and overwintering depths, particularly in high-latitude regions. We use OPtimality-based PLAnkton (OPPLA) ecosystem model) to simulate SVM behavior in zooplankton in the Labrador Sea. Zooplankton in OPPLA is a generic functional group without life cycle, which facilitates analyzing SVM evolutionary stability and interactions between SVM and the plankton ecosystem. A sensitivity analysis of SVM-related parameters reveals that SVM can amplify the seasonal variations of phytoplankton and zooplankton and enhance the reduction of summer surface nutrient concentrations. SVM is often explained as a strategy to reduce exposure to visual predators during winter. We find that species doing SVM can persist and even dominate the summer-time zooplankton community, even in the presence of Stayers, which have the same traits as the migrators, but do not perform SVM. The advantage of SVM depends strongly on the timing of the seasonal migrations, particularly the day of ascent. The presence of higher (visual) predators tends to suppress the Stayers in our simulations, whereas the SVM strategy can persist in the presence of non-migrating species even without higher predators.

    Regional Variation in Extratropical North Atlantic Air‐Sea Interaction 1960–2020 (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-06-24
    Description: Air-sea interaction in late boreal winter is studied over the extratropical North Atlantic (NA) during 1960–2020 by examining the relationship between sea-surface temperature (SST) and total turbulent heat flux (THF). The two quantities are positively correlated on interannual timescales over the central-midlatitude and subpolar NA, suggesting the atmosphere on average drives SST and THF variability is independent of SST. On decadal timescales and over the central-midlatitude NA the correlation is negative, suggesting ocean processes on average drive SST and THF variability is sensitive to SST. The correlation is positive over the subpolar NA. There, interannual and decadal THF variability is governed by the North Atlantic Oscillation (NAO). During the major late 20th and early 21st century SST increase in the subpolar NA diminishing oceanic heat loss associated with a weakening NAO was observed. This study suggests that the atmosphere is more sensitive to SST over the central-midlatitude than subpolar NA. Key Points: - Regional variation in the nature of air-sea interaction over the extratropical North Atlantic (NA) north of 35°N - Timescale dependence in relationship between sea-surface temperature (SST) and turbulent heat flux over the central-midlatitude NA - The atmosphere is more sensitive to SST variability over the central-midlatitude than subpolar NA

    Early arrival of spring‐spawning Atlantic herring Clupea harengus at their spawning ground in the Kiel Fjord, western Baltic, relates to increasing winter seawater temperature (2024)
    Wiley
    Details
    Publication Date: 2024-06-24
    Description: The disturbance of marine organism phenology due to climate change and the subsequent effects on recruitment success are still poorly understood, especially in migratory fish species, such as the Atlantic herring (Clupea harengus; Clupeidae). Here we used the commercial catch data from a local fisher over a 50-year period (1971–2020) to estimate western Baltic spring-spawning (WBSS) herring mean arrival time Q50 (i.e., the week when 50% of the total fish catches had been made) at their spawning ground within the Kiel Fjord, southwest Baltic Sea, and the duration of the spawning season for each year. The relationship between the seawater temperature in the Kiel Bight and other environmental parameters (such as water salinity, North Atlantic and Atlantic multidecadal oscillations) and Q50 was evaluated using a general linear model to test the hypothesis that fish arrived earlier after warm than cold winters. We also estimated the accumulated thermal time to Q50 during gonadal development to estimate the effects of seawater temperature on the variations of Q50. The results of this study revealed a dramatic decrease in herring catches within the Kiel Fjord since the mid-1990s, as documented for the whole southwestern Baltic Sea. Warmer winter seawater temperature was the only factor related to an earlier arrival (1 week for one January seawater temperature degree increase) of herring at their spawning ground. The relationship was found for the first time on week 52 of the year prior to spawning and was the strongest (50% of the variability explained) from the fourth week of January (8 weeks before the mean Q50 among the studied years). A thermal constant to Q50 (~316°C day) was found when temperatures were integrated from the 49th week of the year prior to spawning. These results indicate that seawater temperature enhanced the speed of gonadal maturation during the latest phases of gametogenesis, leading to an early fish arrival under warm conditions. The duration of the spawning season was elongated during warmer years, therefore potentially mitigating the effects of trophic mismatch when fish spawn early. The results of this study highlight the altering effects of climate change on the spawning activity of a migratory fish species in the Baltic Sea where fast global changes presage that in other coastal areas worldwide

    Modulation of Equatorial Currents and Tropical Instability Waves During the 2021 Atlantic Niño (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-06-30
    Description: In the boreal summer of 2021, the equatorial Atlantic experienced the strongest warm event, that is, Atlantic Niño, since the beginning of satellite observations in the 1970s. Such events have far‐reaching impacts on large‐scale wind patterns and rainfall over the surrounding continents. Yet, developing a paradigm of how Atlantic Niño interacts with the upper‐ocean currents and intraseasonal waves remains elusive. Here we show that the equatorial Kelvin wave associated with the onset of the 2021 Atlantic Niño modulated both the background flow and the eddy flux of the equatorial upper‐ocean circulation, causing an extremely weak and delayed tropical instability wave (TIW) season. TIW‐induced variations of sea surface temperature (SST), sea surface salinity, sea surface height, and eddy temperature advection were exceptionally weak during May to July, the climatological peak of TIW activity, but rebounded in August when higher than normal variability was observed. Moored velocity data at 23°W show that during the peak of the 2021 Atlantic Niño from June to August, the Equatorial Undercurrent was deeper and stronger than usual. An anomalously weak eddy momentum flux strongly suppressed barotropic energy conversion north of the equator from May to July, likely contributing to low TIW activity. Reduced baroclinic energy conversion also might have played a role, as the meridional gradient of SST was sharply reduced during the Atlantic Niño. Despite extremely weak TIW velocities, modest intraseasonal variability of chlorophyll‐a (Chl‐ a ) was observed during the Atlantic Niño, due to pronounced meridional Chl‐ a gradients that partly compensated for the weak TIWs. Plain Language Summary Every few years the eastern equatorial Atlantic Ocean is significantly warmer than usual during boreal summer. Such warm events are referred to as Atlantic Niño events, and share similarities with El Niño events in the Pacific. In 2021, the strongest Atlantic Niño in at least four decades was observed in the equatorial Atlantic. This study is the first that investigates the complex interaction between Atlantic Niño, tropical Atlantic upper‐ocean currents, and equatorial waves based on various observational data sets. We show that the developing 2021 Atlantic Niño weakened both the background flow and the variability of near‐surface currents in May, which in turn largely reduced the strength of intraseasonal (20–50 days) waves that are usually generated by instability of the upper‐ocean zonal currents. As a consequence, the cooling effect that these waves usually have north of the equator and the warming effect along the equator vanished from May to July 2021. Interestingly, variability of chlorophyll concentration was enhanced, suggesting that enhanced meridional chlorophyll gradients compensated for reduced wave activity. Key Points The developing 2021 Atlantic Niño led to weaker equatorial surface currents and reduced vertical shear of upper‐ocean horizontal velocity Strong reduction of the surface flow, eddy flux, and meridional temperature gradient in May caused extremely weak and delayed tropical instability wave (TIW) season Reduced meridional TIW advection contributed to sharpen the north equatorial Chl‐ a front resulting in modest intraseasonal Chl‐ a variability

    Influence of Hydrodynamics on the Composition and Reactivity of Particulate Organic Matter in a Large River Influenced Ocean Margin (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-07-01
    Description: Marginal seas influenced by large rivers are characterized by complex hydrodynamic and organic matter cycling processes. However, the impacts of hydrodynamics on the composition and reactivity of particulate organic matter (POM) remain unclear. Here we conducted a comprehensive study on the bulk, molecular and biological properties of suspended POM in the Changjiang Estuary and adjacent area subjected to strong currents, eddies as well as typhoons during spring and autumn. D/L‐enantiomers of particulate amino acids (PAA) were analyzed to evaluate the bioreactivity of POM and quantify bacterial‐derived organic carbon. We found that POM bioavailability as indicated by carbon‐normalized yields of PAA (PAA‐C%) reflected the ecosystem productivity. Relatively high PAA‐C% values (20−35%) were observed in productive areas influenced by Changjiang River plume, cyclonic eddies and typhoons, likely related to the enhanced nutrient availability arising from hydrodynamic processes. In contrast, the oligotrophic Taiwan Warm Current‐influenced regions featured relatively low POM bioavailability (PAA‐C% 〈 10%) despite typhoons facilitating water mixing. The PAA‐C% values showed a significant positive correlation with extracellular enzyme activity, indicating that bioavailable POM can rapidly stimulate heterotrophic transformation. Hot spots of elevated bioavailable POM showed high contributions of bacterial organic carbon. A large portion (∼2/3) of bacterial organic carbon was present in the form of bacterial detritus, suggesting that patches of these biological hot spots represent important sites of carbon sequestration. Together, our findings indicate that fresh POM production is largely controlled by nutrient supply driven by hydrodynamic processes, with important implications for carbon sequestration in the dynamic ocean margins. Plain Language Summary Marginal seas are subject to complex hydrodynamic processes and play an important role in carbon sequestration. Disentangling the linkages between hydrodynamics and organic carbon reactivity and composition is crucial to understanding the regional carbon cycle. Here we collected suspended particulate organic matter (POM) in the Changjiang Estuary and adjacent coastal areas. Based on the biomarker D/L‐amino acids, we assessed the bioavailability of POM and quantified the organic carbon originating from bacteria. We found that high bioactivity of POM occurred in productive Changjiang River plume, cyclonic eddy, and typhoon influenced areas. These hydrodynamic processes appear to increase nutrient availability, therefore promoting phytoplankton growth. Bioavailable POM can rapidly stimulate heterotrophic activity and facilitate the transformation of algal‐derived organic carbon to bacterial detritus, thus contributing to carbon sequestration. Our findings suggest that the production of bioavailable POM is largely controlled by hydrodynamically driven nutrient supply. Key Points We use D/L‐amino acids to assess the bioreactivity and bacterial origins of particulate organic matter (POM) in the dynamic Changjiang Estuary and adjacent area High bioavailability of POM occurs in productive regions affected by Changjiang River plume, cyclonic eddies and typhoons Hot spots of bioavailable POM represent important sites for carbon sequestration

    Temporal Variability of Ventilation in the Eurasian Arctic Ocean (2024)
    AGU (American Geophysical Union) | Wiley
    Details
    Publication Date: 2024-07-01
    Description: The Arctic Ocean plays an important role in the regulation of the earth's climate system, for instance by storing large amounts of carbon dioxide within its interior. It also plays a critical role in the global thermohaline circulation, transporting water entering from the Atlantic Ocean to the interior and initializing the southward transport of deep waters. Currently, the Arctic Ocean is undergoing rapid changes due to climate warming. The resulting consequences on ventilation patterns, however, are scarce. In this study we present transient tracer (CFC-12 and SF6) measurements, in conjunction with dissolved oxygen concentrations, to asses ventilation and circulation changes in the Eurasian Arctic Ocean over three decades (1991–2021). We constrained transit time distributions of water masses in different areas and quantified temporal variability in ventilation. Specifically, mean ages of intermediate water layers in the Eurasian Arctic Ocean were evaluated, revealing a decrease in ventilation in each of the designated areas from 2005 to 2021. This intermediate layer (250–1,500 m) is dominated by Atlantic Water entering from the Nordic Seas. We also identify a variability in ventilation during the observation period in most regions, as the data from 1991 shows mean ages comparable to those from 2021. Only in the northern Amundsen Basin, where the Arctic Ocean Boundary Current is present at intermediate depths, the ventilation in 1991 is congruent to the one in 2005, increasing thereafter until 2021. This suggests a reduced ventilation and decrease in the strength of the Boundary Current during the last 16 years. Key Points Temporal variability of ventilation in the Eurasian Arctic Ocean during the past 30 years is estimated by observations of transient tracers We found a slow down of the ventilation between 2005 and 2021 in the intermediate waters Evidence of multidecadal variability of ventilation in the intermediate waters of the Eurasian Arctic Ocean is present Plain Language Summary The Eurasian Arctic Ocean, the region of the Arctic Ocean connected to the European and Asian continents, is an important pathway for recently ventilated water from the Nordic Seas. These waters are exported back to the North Atlantic following their travel through the Arctic Ocean. Ventilation describes the process of surface waters being transported into the interior ocean due to increasing density, which affects the underlying water masses. In this study we investigate how the ventilation patterns have evolved in the Eurasian Arctic Ocean over the past three decades, using transient tracer (CFC-12 and SF6) measurements. We observed a significant change in the intermediate layer (250–1,500 m) with older waters found in measurements in 1991 and 2021 compared to 2005 and 2015. Moreover, our data suggest a slowdown in ventilation throughout the three decades in the northern Amundsen Basin, implying a decrease in the circulation time-scale of the Arctic Ocean Boundary Current over the past 16 years. This has potentially important implications for the transport of, for example, heat, salt or oxygen from the Atlantic Ocean around the Arctic Ocean, and back.

    Positive Obligations under the European Convention on Human Rights (2023)
    Oxford University Press
    Details
    Publication Date: 2023-11-17
    Description: This book identifies and explains the key analytical issues (state knowledge, causation, and reasonableness) that need to be considered in determining whether a State is responsible under the European Convention on Human Rights for omissions. In addition to this technical analytical question, the book also reflects upon what is at stake for the political community when the triggering, the content, and the scope of positive human rights obligations are determined. A central question is then how the search for a balance between intrusion and restraint by the State, between protection and freedom from invasion, defines this community and pulls the analysis of state responsibility for omissions in different directions. Designed to become the main reference source concerning ECHR positive obligations, this book makes four main contributions. First, it covers an important gap by isolating and studying the separate analytical elements (state knowledge, causation, and reasonableness) underlying state responsibility for failure to fulfil positive obligations. It explains the structure of review, the analytical steps taken to ascertain state responsibility for omissions. Secondly, the book offers a serious appreciation of the dangers associated with positive obligations whose scope might be too expansive or content too intrusive. Thirdly, it explains the different types of positive obligations. Fourthly, it offers the first examination of the conceptual hurdles if positive obligations under the ECHR were to be applied extraterritorially.

    Business Ethics (2023)
    Oxford University Press
    Details
    Publication Date: 2024-03-30
    Description: Business ethics continues to gain importance in the curricula of business studies courses. This book provides a comprehensive overview of both the essential concepts of business ethics related to the economy as a whole, and the more narrowly understood corporate ethics related to the individual company. In contrast to other works on the same topic, special emphasis is placed on a coherent theoretical foundation that puts tools of economic analysis, including behavioral economics, at the center. In particular, the importance of both empirical research and dilemma structures for business ethics receives special attention. The largest chapter of the book is devoted to corporate ethics and provides students and academics with guidance in the theoretical classification of the variety of concepts that often coexist in the debate. Abstract concepts are illustrated with the help of practice boxes.

    The Concept of Democracy (2023)
    Oxford University Press
    Details
    Publication Date: 2024-03-24
    Description: If we don’t know what the words “democracy” and “democratic” mean, then we don’t know what democracy is. This book defends a radical view: these words mean nothing and should be abandoned. The argument for abolitionism is simple: those terms are defective and we can easily do better, so let’s get rid of them. According to the abolitionist, the switch to alternative devices would be a significant communicative, cognitive, and political advance. The first part of the book presents a general theory of abandonment: the conditions under which language should be abandoned. The rest of the book applies this general theory to the case of “democracy” and “democratic”. The book shows that “democracy” and “democratic” are semantically, pragmatically, and communicatively defective. Abolitionism is not all gloom and doom. It also contains a message of good cheer: we have easy access to conceptual devices that are more effective than “democracy”. We can do better. These alternative linguistic devices will enable us to ask better questions, provide genuinely fruitful answers, and have more rational discussions. Moreover, those questions and answers better articulate the communicative and cognitive aims of those who use empty terms such as “democracy” and “democratic”.

    Data Sovereignty (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-14
    Description: Digital sovereignty—the exercise of control over the Internet—is the ambition of the world’s leaders, from Australia to Zimbabwe, a bulwark against both foreign state and foreign corporation. Governments have resoundingly answered first-generation Internet law questions of who if anyone should regulate the Internet—they all will. The second-generation question to confront is not whether, but how to regulate the Internet. This volume features new theoretical perspectives on digital sovereignty and explores cutting-edge issues associated with it. Drawing mainly on various theories concerning political economy, international law, human rights, and data protection, it presents thought-provoking ideas about the nature and scope of digital sovereignty. It also examines the extent to which new technological developments in sectors, such as artificial intelligence, e-commerce, and sharing economy, have posed challenges to assertion of digital sovereignty, and considers how to deal with such challenges. In particular, the volume discusses the promise and pitfalls of digital sovereignty in the process of trade liberalization, data localization, and human rights protection.

    Public Policy to Reduce Inequalities across Europe (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-07
    Description: There is a broad consensus across European states and the EU that social and economic inequality is a problem that needs to be addressed. Yet inequality policy is notoriously complex and contested. This book approaches the issue from two linked perspectives. First, a focus on functional requirements highlights what policymakers think they need to deliver policy successfully, and the gap between their requirements and reality. We identify this gap in relation to the theory and practice of policy learning, and to multiple sectors, to show how it manifests in health, education, and gender equity policies. Second, a focus on territorial politics highlights how the problem is interpreted at different scales, subject to competing demands to take responsibility. This contestation and spread of responsibilities contributes to different policy approaches across spatial scales. We conclude that governments promote many separate equity initiatives, across territories and sectors, without knowing if they are complementary or contradictory. This outcome could reflect the fact that ambiguous policy problems and complex policymaking processes are beyond the full knowledge or control of governments. It could also be part of a strategy to make a rhetorically radical case while knowing that they will translate into safer policies. It allows them to replace debates on values, regarding whose definition of equity matters and which inequalities to tolerate, with more technical discussions of policy processes. Governments may be offering new perspectives on spatial justice or new ways to reduce political attention to inequalities.

    Chapter 8 Ethics of Selective Restriction of Liberty in a Pandemic (2023)
    Oxford University Press
    Details
    Publication Date: 2024-03-28
    Description: Liberty-restricting measures are basic measures in combatting any pandemic. But whose liberty should be restricted? One standard response in public health ethics is to appeal to the “least restrictive alternative” necessary to achieve a public health goal. The problem is that in practice, greater restriction of liberty can lead to greater control of the pandemic and save more lives, though with increasing burdens to others. Liberty restriction is thus a question of the distribution of benefitsbenefits benefits and burdens in a population, a question of distributive justice. In this chapter, I argue that in some pandemics, such as COVID-19, it may be a more proportionate restriction of liberty to restrict the liberty of certain groups, rather than the population as a whole. Two arguments were given in the COVID-19 pandemic for liberty restriction: (1) protection of the vulnerable; (2) protection of the health service. These These are, however, more fundamentally issues about distributive justice. I explore how several approaches to distributive justice can support the differential differential differentialdifferentialdifferential restriction of liberty. In addition, I argue that the commonly accepted justificationjustificationjustificationjustificationjustification justification justification justification for liberty restrictions (that liberty restrictions may be justifiedjustifiedjustifiedjustifiedjustified justified to prevent direct harm to others) - can be overly simplistic, as illustrated by the COVID-19 pandemic. I argue that where risk groups (such as the elderly in the COVID-19 pandemic) are more likely to utilise limited health resources, they pose an indirect threat to others during the pandemic that warrants coercion. I argue there should be a side-constraint on justice of non-maleficence.non-maleficence.non-maleficence. non-maleficence. non-maleficence. non-maleficence. This This requires that there is a limit to harm which can be imposed on individuals for others, best captured by a collective duty of easy rescue. For groups such as the young, vaccination or lockdown may not constitute an “easy rescue” of those at greatest risk. I address the issue of whether selective restriction of liberty constitutes unjust discrimination and I propose an algorithm for making decisions about selective restriction of liberty.

    Mario Lavista (2023)
    Oxford University Press
    Details
    Publication Date: 2024-03-24
    Description: Composer, pianist, editor, writer, and pedagogue Mario Lavista (1943-2021) was a central figure of the cultural and artistic scene in Mexico and one of the leading Ibero-American composers of his generation. His music is often described as evocative and poetic, noted for his meticulous attention to timbre and motivic permutation, and his creative trajectory was characterized by its intersections with the other arts, particularly poetry and painting. Lavista was a relational composer; he did not write music as a private enterprise but for and alongside people with whom he established close relations. Understanding analysis as an affective practice, author Ana R. Alonso-Minutti explores the intertextual connections between the multiple texts--musical or otherwise--that are present in Lavista's music. Alonso-Minutti argues that, through adopting an interdisciplinary and transhistorical approach to music composition, Lavista forged a cosmopolitan imaginary that challenged stereotypes of what Mexican music should sound like. This imaginary becomes a strategy of resistance against imperialist agendas placed upon postcolonial peripheries. Departing from traditional biographical and chronological frameworks that exalt masters and masterworks, the author offers a nuanced, personal narrative informed by conversations with composers, performers, artists, choreographers, poets, writers, and filmmakers. Through an innovative mosaic of methodologies, from archival work, to musical and intertextual analysis, oral history, and (auto)ethnography, this book is the first in-depth study of Lavista's compositional career and offers a contextual panorama of the contemporary music scene in Mexico

    Chapter 2 The return and spread of the transnational mining corporation in the African periphery (2023)
    Oxford University Press
    Details
    Publication Date: 2023-11-18
    Description: The aim of this chapter is to historically situate the case of mining in the Congo within its broader regional context. It is organized in three sections, each corresponding to a separate stage of the process that led to transnational mining corporations once again becoming the dominant force assuming ownership and management of industrial mining projects across the continent. The first stage involved a diagnosis of the economic challenges faced by African economies from the mid-1970s as due to misguided state intervention and government corruption. Based on this diagnosis, during the second stage, the IMF and the World Bank advocated for, financed, and in many instances directly oversaw the liberalization, privatization, and deregulation of mining sectors in low-income African economies. The third stage required criminalizing African miners involved in labour-intensive forms of production and, if required, forcibly displacing them to make way for the construction of capital-intensive, foreign corporate-owned mines.

    The Rise and Fall of the People's Parties (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-02
    Description: The decline of the centre-left and centre-right people’s parties is arguably the most poignant feature of the crisis of democracy in Western Europe today. To understand why, this book explores the striking parallels between the life of democracy and that of the people’s parties over the course of the past century. It offers a transnational window on the history of democracy since 1918 by weaving together three epochs which are often studied apart: democracy’s troubled history in the Interwar era; the trente glorieuses after the Second World War; and the period since the 1970s. The book shows that democracy was only stabilized and legitimized when people’s parties emerged that managed to balance between facilitating popular participation from below, bridging divisions between social groups, and practising the politics of compromise. Ideas for such parties existed already in the first decades of the twentieth century. Nonetheless, Socialist and Catholic mass parties failed to transform into people’s parties, which was essential for the crisis (and breakdown) of democracy in the Interwar era. This was a traumatic experience which contributed to the unexpected stabilization of democracy after 1945 as party leaders transformed their organizations into broad-based people’s parties that embraced compromise and responsibility. However, this stability did not last, and paradoxically their transformation also harboured the seeds of democracy’s more recent problems. Over the past decades, people’s parties have struggled to connect to an individualizing society while having become increasingly absorbed by their governing responsibilities.

    Franco's Internationalists (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-02
    Description: This book tells the story of the experts who sold the idea of Franco’s ‘social state’. Despite the repression, violence, and social hardship which characterized Spanish life in the 1940s and 1950s, the Franco regime sought to win popular support by promoting its apparent commitment to social justice. This book reveals the vital role which the idea of the social state also played in the regime’s ongoing search for international legitimacy. It shows how social experts, particularly those working in the fields of public health, medicine, and social insurance, were at the forefront of efforts to promote the regime to the outside world. By working with international organizations and transnational networks across Europe, Africa, and Latin America, they sought to sell the idea of Franco’s Spain as a respectable, modern, and socially just state. In doing so the book also seeks to disrupt our understanding of the modern history of internationalism. Exploring what it meant for Francoist experts to think and act internationally, it challenges dominant accounts of internationalism as a liberal, progressive movement by foregrounding the history of fascist, nationalist, imperialist, and religious forms of international cooperation. The case of Spain reveals the contested and heterogenous nature of mid-twentieth-century internationalism, characterized by the tumultuous interplay of overlapping global, regional, and imperial projects. It also brings into focus the overlooked continuities between international structures and projects before and after 1945.

    Publication Date: 2024-04-06
    Description: Between 1815 and 1870, when European industrialisation was in its infancy and Britain enjoyed a technological lead, thousands of British workers emigrated to the Continent. They played a key role in several sectors such as textiles, iron, mechanics, and the railways. These men and women thereby contributed significantly to the industrial take-off in continental Europe. This book examines the lives and trajectories of these workers, who emigrated from manufacturing centres in Britain to France, Belgium, Germany, and other countries. It is interested in their mobilities, their culture, their politics, and their relations with the local populations. It reminds us that the British economy was not just orientated towards the Empire and the United States, but also towards the Continent, long before the European Union and Brexit. It shows how critical the part played by migrant workers in the industrial revolution was. Artisans Abroad is the first social and cultural history of this forgotten migration.

    Polycentrism (2023)

    Description: How does governing work today? How does society (mis)handle pressing challenges such as armed violence, cultural difference, ecological degradation, economic restructuring, geopolitical shifts, global pandemics, migration flows, and technological change in ways that are democratic, effective, fair, peaceful, and sustainable? This book addresses this key question around the theme of ‘polycentrism’: i.e. the idea that contemporary governing is dispersed, fluctuating, messy, elusive, and headless. Chapters develop this notion of polycentrism from a broad spectrum of academic disciplines and theoretical approaches. Readers thereby obtain a full coverage of exciting new thinking about how today’s world is (mis)ruled. The book distinguishes four paradigms of knowledge about polycentric governing—organizational, legal, relational, structural—and pursues conversations across the divides that normally keep these approaches in separate research communities. These exceptional inter-paradigm exchanges focus especially on issues of techniques (how governing is done), power (what forces drive governing), and legitimacy (whether governing is rightful). Comparisons between the multiple perspectives on polycentric governing highlight, and help to clarify, the distinctive emphases, potentials, and limitations of each approach. In addition, combinations across the diverse theories generate promising novel avenues of thought about polycentrism. Through their engagement with the book, readers can develop their own understandings of governing today and thereby become more empowered political subjects.

    Disrupted Development in the Congo (2023)
    Oxford University Press
    Details
    Publication Date: 2023-11-18
    Description: Since the turn of the century, low-income African countries have undergone a process of mining industrialization led by transnational corporations. The process has been sustained by an African Mining Consensus uniting international financial institutions, African governments, development agencies, and various strands of the academic literature. The Consensus holds that transnational mining corporations are best placed to drive structurally transformative processes of mining-based development on the continent. State-owned enterprises and local forms of labour-intensive mining are deemed unsuitable. The former is characterized as corrupt and mismanaged, and the latter as an inefficient, subsistence activity with links to conflict financing. Through a detailed case study of gold mining in the Democratic Republic of the Congo, Disrupted Development in the Congo reveals the fragile foundations on which this consensus rests. The book documents how foreign mining corporations in the Congo have been prone to mismanagement, inefficiencies, and rent-seeking, and implicated in fuelling conflict and violence. In addition, the book details how structural impediments to the transformative effects of mining industrialization in low-income settings occur irrespective of ownership and management structures. In light of these constraints, and the levels of overseas surplus extraction and domestic marginalization associated with foreign-owned industrial mining, a shift to domestic-owned forms of mining-based development would better meet the needs of low-income African economies for rising productivity, labour absorption, and the domestic retention of the value generated by productive activity than the currently dominant but disarticulated and disruptive foreign corporate-led model.

    Publication Date: 2024-04-02
    Description: For victims of persecution, attracting international awareness of their plight is often a matter of life and death. This book uncovers how in seventeenth-century Europe, persecuted minorities first learned how to use the press as a weapon to combat religious persecution. To mobilize foreign audiences, they faced an acute dilemma: how to make people care about distant suffering? This study argues that by answering this question, they laid the foundations of a humanitarian culture in Europe. The book reveals how, as consuming news became an everyday practice for many Europeans, the Dutch Republic emerged as an international hub of printed protest against religious violence. It traces how a diverse group of people, including Waldensian refugees, Huguenot ministers, Savoyard officeholders, and many others, all sought access to the Dutch printing presses to raise transnational solidarity for their cause. By examining their publicity strategies, this study deepens our understanding of how people tried to confront the specter of religious violence that had haunted them for generations.

    Pockets of Effectiveness and the Politics of State-building and Development in Africa (2023)

    Details
    Publication Date: 2023-08-17
    Description: Why do certain parts of the state in Africa work so effectively despite operating in difficult governance contexts? How do 'pockets of bureaucratic effectiveness' emerge and become sustained over time? And what does this tell us about the prospects for state-building and development in Africa? Repeated economic and social crises have demanded that development thinkers and policy actors have had to engage with the critical role that states play in delivering development. Pockets of Effectiveness and the Politics of State-building and Development in Africa shows that politics is the driving factor that shapes how well state agencies perform their roles. It deploys a new conceptual framework – the power domains approach – to explore the shifting fortunes of key state agencies in five countries – Ghana, Kenya, Rwanda, Uganda, and Zambia – over the past three decades. Our original research reveals when, how and why political rulers decide to build effective state agencies and enable them to deliver certain forms of economic development – often through forming strategic coalitions with senior bureaucrats and with international support – and also when this support falters and gives way to a politics of survival. Comparative analysis identifies two potential trajectories towards state-building in Africa, each shaped by different configurations of social and political power. The book critiques the role that international development agencies have played in (mis)shaping the state in Africa and suggests a new strategic agenda for building the state capacities required to deliver sustained development at the current juncture. The book closes with critical commentaries from two leading scholars in the field, to help place our work in context and establish the next steps for research and strategy in this increasingly important area of development theory and practice.

    Publication Date: 2024-03-24
    Description: The aim of this book is to characterize a notion of type which will cover both linguistic and non-linguistic action and to lay the foundations for a theory of action based on a theory of types called TTR (a Theory of Types with Records). The book argues that a theory of language based on action allows us to take a perspective on linguistic content which is centred on interaction in dialogue and that this is importantly different to the traditional view of natural languages as being essentially similar to formal languages such as logics developed by philosophers or mathematicians. At the same time it will argue that the tremendous technical advances made by the formal language view of semantics can be incorporated into the action-based view and that this can lead to important improvements both of intuitive understanding and empirical coverage. In this enterprise we use types rather than possible worlds as commonly employed in studies of the semantics of natural language. Types are more tractable than possible worlds and give us more hope of understanding the implementation of semantics both on machines and in biological brains.

    Description: This introductory chapter sets out the book’s aims and contributions, outlines its main lines of argument, and details the theoretical foundations underpinning the African Mining Consensus, which holds that transnational mining corporations are best placed to drive structurally transformative processes of mining-based development on the continent. It then moves on to document how, in establishing this Consensus position, proponents have tended to misrepresent or disregard some of the classic critiques mounted by a group of pioneering early development economists. These critiques focused on the specific challenges and constraints faced by income-poor peripheral countries seeking development through deeper integration with the global capitalist economy. Returning to these earlier critiques provides helpful lenses with which to explore, with some adaptation, several axes of tension within the ongoing process of foreign corporate-led mining industrialization in low-income African countries that are overlooked by the absent or simplistic representation of these critiques by Consensus proponents.

    Randomized Control Trials in the Field of Development (2023)

    Publication Date: 2023-01-22
    Description: In October 2019, Abhijit Banerjee, Esther Duflo, and Michael Kremer jointly won the 51st Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel "for their experimental approach to alleviating global poverty." But what is the exact scope of their experimental method, known as randomized control trials (RCTs)? Which sorts of questions are RCTs able to address and which do they fail to answer? This book provides answers to these questions, explaining how RCTs work, what they can achieve, why they sometimes fail, how they can be improved and why other methods are both useful and necessary. Chapters contributed by leading specialists in the field present a full and coherent picture of the main strengths and weaknesses of RCTs in the field of development. Looking beyond the epistemological, political, and ethical differences underlying many of the disagreements surrounding RCTs, it explores the implementation of RCTs on the ground, outside of their ideal theoretical conditions and reveals some unsuspected uses and effects, their disruptive potential, but also their political uses. The contributions uncover the implicit worldview that many RCTs draw on and disseminate, and probe the gap between the method's narrow scope and its success, while also proposing improvements and alternatives. This book warns against the potential dangers of their excessive use, arguing that the best use for RCTs is not necessarily that which immediately springs to mind, and offering opportunity to come to an informed and reasoned judgement on RCTs and what they can bring to development.

    The Job Ladder (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-07
    Description: Using a range of countries from the Global South, this book examines heterogeneity within informal work by applying a common conceptual framework and empirical methodology. The country studies use panel data to study the dynamics of worker transitions between formal and heterogeneous, informal work. The range of country studies in the book (covering Asia, Latin America, the Middle East, and North Africa and sub-Saharan Africa) allow us to present a comparative perspective across developing countries. Each country study provides a nuanced view of informality, dividing workers into six work status groups: formal wage-employees, upper-tier informal wage-employees, lower-tier informal wage-employees, formal self-employed, upper-tier informal self-employed, and lower-tier informal self-employed. Based on this common conceptual framework, the country studies examine the distribution of workers between each of these work status groups. Using panel data, the country studies document transition patterns across different formality and work status groups. The panel data analysed in each country study gives a basis for making statements about labour market transitions that are not warranted when using comparable cross sections. In addition to measuring the distribution of workers and transitions between work status groups, each country study also examines individual-level and household-level characteristics associated with workers in each work status. Using these characteristics, each country study constructs a ‘job ladder’ that ranks each work status. The country studies then examine the characteristics of workers that are associated with transitions up (and down) the job ladder.

    The French Invention of Menopause and the Medicalisation of Women's Ageing (2023)
    Oxford University Press
    Details
    Publication Date: 2024-03-31
    Description: Doctors writing about menopause in France vastly outnumbered those in other cultures throughout the entire nineteenth century. The concept of menopause was invented by Frenchmen medical students in the aftermath of the French Revolution, becoming an important pedagogic topic and a common theme of doctors’ professional identities in postrevolutionary biomedicine. Older women were identified as an important patient cohort for the expanding medicalisation of French society and were advised to entrust themselves to the hygienic care of doctors in managing the whole era of life from around and after the final cessation of menses. However, menopause owed much of its conceptual weft to earlier themes of women as the sicker sex, of vitalist crisis, of the vapours, and of astrological climacteric years. This book is the first comprehensive study of the origins of the medical concept of menopause, richly contextualising its role in nineteenth-century French medicine and revealing the complex threads of meaning that informed its invention. It tells a complex story of how women’s ageing featured in the demographic revolution in modern science, in the denigration of folk medicine, in the unique French field of hygiène, and in the fixation on women in the emergence of modern psychiatry. It also reveals the nineteenth-century French origins of the still-current medical and alternative-health approaches to women’s ageing as something to be managed through gynaecological surgery, hormonal replacement, and lifestyle intervention.

    Lexical Variation and Change (2023)
    Oxford University Press
    Details
    Publication Date: 2024-03-24
    Description: Distributional semantics embodies the idea that the context in which a word occurs reveals the meaning of that word. In contemporary corpus linguistics, that idea takes shape in various types of quantitative context analysis. This monograph explores how count-based token-level semantic vector spaces, as an advanced form of such a quantitative methodology, can be applied to the study of polysemy, lexical variation, and lectometry. What can distributional models reveal about meaning? How can they be used to analyse the semantic relationship between near-synonyms? And how can they contribute to the study of lexical variation as a sociolinguistic variable? The book details the conceptual background of lexical semantic and lexical variation research, explains the mechanism of distributional modelling, and introduces distributional workflows and corpus linguistic tools to answer the questions. Combining a cognitive linguistic interest in meaning with a sociolinguistic interest in variation, it illustrates that distributional methodology with case studies on Dutch and Spanish lexical data, focusing on the value of distributional models for semantic analysis, the interaction of semasiological and onomasiological change, and sociolinguistic issues of lexical standardization and pluricentricity.

    Chapter 3 Foreign mining corporations on trial (2023)

    Details
    Publication Date: 2023-11-18
    Description: By the 2010s, the view that state mismanagement and inefficiencies underlay the Congo’s economic malaise had become so commonplace as to permeate nearly all thinking about development in the country. The aim of this chapter is to challenge this line of thinking and question the Consensus wisdom of moving from domestic-owned to foreign-owned industrial mining based on a belief in the superior efficiency of the latter. By charting the rise and fall of Belgian-owned SOMINKI (1976-1997) and Canadian-owned Banro (1995-2019) in eastern Congo, its main line of argument is that foreign-owned and managed mining corporations are no less vulnerable to mismanagement, firm inefficiencies, and volatile prices than their state-owned counterparts. This included, in the case of Banro, rent-seeking behaviour, redirecting value to overseas directors and shareholders at the expense of productive capacity and to the detriment of the Congolese state and Congolese firms and labour.

    Russian Approaches to International Law (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-07
    Description: This book examines Russian approaches to international law from three different yet closely interconnected perspectives: history, theory, and recent state practice. The study uses comparative international law as a starting point and argues that in order to understand post-Soviet Russia’s state and scholarly approaches to international law, one should take into account the history of ideas in Russia. To some extent, Russian understandings of international law differ from what is considered the mainstream in the West. One specific feature of this work is that it goes inside the language of international law as it is spoken and discussed in post-Soviet Russia, especially the scholarly literature in the Russian language, and relates this literature to the history of international law as discipline in Russia. Recent state practice such as the annexation of Crimea in 2014, Russia’s record in the UN SC, the European Court of Human Rights, investor-state arbitration, and the creation of the Eurasian Economic Union are laid out and discussed in the context of increasingly popular ‘civilizational’ ideas, i.e. the claim that Russia is a unique civilization and not part of Europe understood as the West. The implications of this claim for the future of international law, its universality and regionalism are discussed. This study concludes the author’s five-year work on ERC-funded grant that enabled him to attend international law conferences in Russia and other CIS countries, as well as get access to relevant sources that often cannot be so easily accessed in the West.

There There are opposing ethical views about how to prioritise, and countries have taken different different differentdifferentapproaches. There There is a strong ethical argument that policies should take a pluralistic approach to allocation that reflectsreflects reflectsreflectsreflectsmultiple ethical values - both because of the diversity of viewpoints within communities and the recognition that there are competing relevant ethical values. In this chapter, I look at the epistemic and normative problems raised by pluralistic allocation in this pandemic and suggest implications for future pandemics. I summarise some of the relevant evidence about the public’s views and values relating to prioritisation. I also explore some practical approaches to prioritisation of scarce resources in the face of contrasting and competing ethical values

    The Rise of Mass Advertising (2023)
    Oxford University Press
    Details
    Publication Date: 2023-10-05
    Description: This book is a first cultural legal history of advertising in Britain, tracing the rise of mass advertising circa 1840–1914 and its legal shaping. The emergence of this new system disrupted the perceived foundations of modernity. The idea that culture was organized by identifiable fields of knowledge, experience, and authority came under strain as advertisers claimed to share values with the era’s most prominent fields, including news, art, science, and religiously inflected morality. While cultural boundaries grew blurry, the assumption that the world was becoming progressively disenchanted, itself closely related to concepts of boundaries, was undermined as enchanted experiences multiplied with the transformation of everyday environments by advertising. Non-rational ontologies and a play of mystery became apparent, involving possibilities for metamorphoses, magical efficacy, animated environments, affective connections between humans and things, imaginary worlds and fantasies that informed mundane lifed. These disrupted assumptions that the capitalist economy was a victory of reason. The Rise of Mass Advertising examines how contemporaries came to terms with the disruptive impact by mobilizing legal processes, powers, and concepts. Law was implicated in performing boundary work that preserved the modern sense of field distinctions. Advertising’s cultural meanings and its organization were shaped dialectically vis-à-vis other fields in a process that mainstreamed and legitimized it with legal means, but also construed it as an inferior simulation of the values of a progressive modernity, exhibiting epistemological shortfalls and aesthetic compromises that marked it apart from adjacent fields. The dual treatment meanwhile disavowed the central role of enchantment, in what amounted to a normative enterprise of disenchantment. One of the ironies of this enterprise was that it ultimately drove professional advertisers to embrace enchantment as their peculiar expertise.

    Confronting Colonial Objects (2023)
    Oxford University Press
    Details
    Publication Date: 2023-11-16
    Description: In 1978, UNESCO Secretary General Amadou-Mahtar M’Bow compared cultural colonial objects to ‘witnesses to history’. Their treatment is one of the most debated questions of our time. Calls for a novel international cultural order go back to decolonization. However, for decades, the issue has been treated as a matter of comity or been reduced to a Shakespearean dilemma: to return or not to return. This book seeks to go beyond these classic dichotomies. It argues that contemporary practices are at a tipping point. It shows that cultural takings were material to the colonial project throughout different periods (early takings, birth of modern nation state, nineteenth-century scramble for objects) and went far beyond looting. It relies on micro histories and object biographies to trace recurring justifications and contestations of takings and returns, and the complicity of anthropology, racial science, and professional networks in colonial collecting. It demonstrates the dual role of law and cultural heritage regulation in enabling colonial injustices, and mobilizing resistance thereto. It challenges the argument that takings were acceptable according to the standards of the time. Drawing on the interplay between justice, ethics, and human rights, it develops a theory of entanglement to rethink contemporary approaches. It shows that future engagement requires a reinvention of knowledge systems and relations towards objects, including new forms of consent, provenance research, partnership and a rethinking of the role of museums themselves. It proposes principles of relational cultural justice to confront ongoing historic, legal, and economic entanglements and enable normative transformation.

    When the Nerds Go Marching In (2023)
    Oxford University Press
    Details
    Publication Date: 2023-12-23
    Description: When the Nerds Go Marching In shows how digital technology has moved from the margins to the mainstream of campaign and election organization in contemporary democracies. Combining an extensive review of existing literature and comparative data sources with original survey evidence and web content analysis of digital campaign content across four nations—the United Kingdom, Australia, France, and the United States—the book maps the key shifts in the role and centrality of the internet in election campaigns over a twenty-year period. The chapters reveal how these countries have followed a four-phase model of digital campaign development which begins with experimentation, and is followed by a period of standardization and professionalization. Subsequent phases focus on increasingly strategic activities around the mobilization of activists and supporters, before switching to micro-targeted mobilizing of individual voters. The changes are mapped over time in each country from the perspective of both the campaigners (supply side), and that of voters (demand side), and the four nations are compared in terms of how far and fast they have moved through the developmental cycle. As well as providing the most comprehensive narrative charting the evolution of digital campaigning from its inception in the mid-1990s, the book also offers important insights into the national conditions that have been most conducive to its diffusion. Finally, based on the findings from the most recent phase of development, the book speculates on the future direction for political campaigns as they increasingly rely on digital tools and artificial intelligence for direction and decision-making during elections.

    Publication Date: 2024-03-31
    Description: The COVID-19 pandemic has been a defining defining event of the 21st century. Global estimates of excess mortality indicate that it has taken fifteen fifteen million lives over 2020-21 (Knutson et al. 2022). It has closed national borders, put whole populations into quarantine and devastated economies. Almost half of workers in low or middle income countries lost a job or business due to the pandemic (Anonymous 2021). The International Monetary Fund has estimated a global loss to the world economy of US$12trillion by the end of 2021 (Bill and Melinda Gates Foundation 2020). It led to a rise in rates of extreme poverty for the first firstfirst time in 25 years, with 37 million additional people experiencing this in 2020. The pandemic toll and the cost of measures taken to combat it—both effective effectiveeffectiveeffectiveeffectiveeffective and ineffective—has ineffective—has ineffective—hasineffective—hasineffective—hasineffective—hasineffective—has ineffective—has been paid in human lives, mental and physical suffering,suffering, suffering, suffering,suffering, and economic hardship. The costs will continue to be paid by individuals and societies for decades to come. While the COVID-19 pandemic has been catastrophic, it is not unique. It is not as severe as Spanish influenza, estimated to have killed between 50-100 million people. Recent MERS and SARS epidemics were more deadly to those infected, but less contagious. Future influenza pandemics, perhaps like the hypothetical example above, undoubtedly lie ahead. We await ‘Disease X’, the World Health Organisation’s placeholder name for “a serious international epidemic … caused by a pathogen currently unknown to cause human disease.” In some ways, the COVID-19 pandemic has been a wake up-call. Children who have been home-schooled during the COVID pandemic will almost certainly face another pandemic in their lifetime – one at least as bad—and potentially much worse—than this one.

    The Many Faces of Socioeconomic Change (2023)
    Oxford University Press
    Details
    Publication Date: 2023-03-03
    Description: This book provides a survey of different ways in which economic sociocultural and political aspects of human progress have been studied since the time of Adam Smith. Inevitably, over such a long time span, it has been necessary to concentrate on highlighting the most significant contributions, rather than attempting an exhaustive treatment. The aim has been to bring into focus an outline of the main long-term changes in the way that socioeconomic development has been envisaged. The argument presented is that the idea of socioeconomic development emerged with the creation of grand evolutionary sequences of social progress that were the products of Enlightenment and mid-Victorian thinkers. By the middle of the twentieth century, when interest in the accelerating development gave the topic a new impetus, its scope narrowed to a set of economically based strategies. After 1960, however, faith in such strategies began to wane, in the face of indifferent results and general faltering of confidence in economists’ boasts of scientific expertise. In the twenty-first century, development research is being pursued using a research method that generates disconnected results. As a result, it seems unlikely that any grand narrative will be created in the future and that neo-liberalism will be the last of this particular kind of socioeconomic theory.

    Advanced Land Warfare (2023)

    Publication Date: 2024-03-29
    Description: International politics have become ever more volatile over the last decade, increasing the risk of large-scale military violence. Yet the precise character of future war will depend on a range of factors that relate to adversaries, allies, technology, geographical scope and multiple domains of warfighting. Few would question that land forces will be important also in the foreseeable future. However, given that the battlefield is in a state of transformation, so is the mission, purpose and utilization of land forces. Indeed, the future conduct of land warfare is subjected to serious and important questions in the face of large and complex challenges and security threats. This volume explores the evolving role of land forces, paying particular attention to the changes that have taken place in the art of commanding and executing combat and the role of rapid technological innovation and information dissemination in shaping warfare. It provides insights into key contemporary developments in land warfare, and presents case studies on land tactics and operations in different national contexts. The volume aims to draw on the best of theory, practice, and professional experience, featuring chapters written by leading international scholars and practitioners. Relating to the realities of the modern battlefield, the volume addresses a number of critical questions about land tactics and operations, combining a conceptual basis with empirical examples of tactical thinking and practice and emphasising the importance of understanding the perspectives of various national armies, in order to provide a current understanding of the central issues of land warfare.

    Undocumented Saints (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-09
    Description: UnDocumented Saints follows the migration of popular saints from Mexico into the United States and the evolution in their meaning. The book explores how Latinx battles for survival are also performed in the worlds of faith, religiosity, and the imaginary and how the sociopolitical realities of exploitation and racial segregation frame popular religious expressions. It analyzes the emergence of interreligious states, transnational ethnic and cultural enclaves unified by faith/religiosity. Following a chronological approach, this book analyzes five vernacular saints who have emerged in Mexico and whose devotions have migrated into the United States in the last one hundred years: Jesús Malverde, a popular bandito turned saint caudillo; Santa Olguita, an emerging feminist saint linked to border women’s experiences of sexual violence and assault; Juan Soldado, a soldier who was a murderer and rapist, who was the main suspect in the death of an eight-year-old victim known now as Santa Olguita, and who is now a patron for undocumented immigrants; Toribio Romo, a Catholic priest whose ghost/spirit has been helping people cross the border into the United States since the 1990s; and La Santa Muerte, a controversial personification of the dead who is particularly popular among some LGBTQ migrants. Each chapter contextualizes a particularly popular saint with broader discourses about the construction of masculinity and the state, the long history of violence against Latina and migrant women, female erasure from history, discrimination against non-normative sexualities, and the United States and Mexico’s investment in the control of religiosity within the discourses of immigration in the United States.

    Ethnoreligious Otherings and Passionate Conflicts (2023)
    Oxford University Press
    Details
    Publication Date: 2024-03-29
    Description: Departing from the mainstream practice and conventional wisdom of materialist and rationalist accounts of internal and intrastate conflicts, the book demonstrates how and why emotions, symbolic predispositions, and perceptions are just as powerful and useful in understanding and explaining these phenomena. By uncovering the invisible albeit concrete emotive, symbolic, and perceptual causal mechanisms underpinning ethnoreligious otherings and the resulting violent protracted conflicts, the book aims to help address the incongruence between how the actual actors operating within these contexts think and act and the existing theories and models of how they are expected to behave. Accordingly, the book has three main goals. First, to highlight the centrality of emotions, symbolic predispositions, and perceptions in providing a more holistic and realistic understanding of otherings and conflicts. Second, to illustrate how the ethnoreligious othering framework developed and applied in the study bolsters and advances process tracing explanations by systematically incorporating context-specific intersubjective meanings into causal accounts of the events under investigation. And third, to emphasize the importance of recognizing religion and nationalism as legitimate constituents and instruments of contemporary realpolitik by underlining their enduring security utility and essence at individual, group, and state levels. As argued and established throughout the book, because the causal mechanisms driving ethnoreligious otherings and passionate conflicts are simultaneously emitting and are propelled by deeply entrenched emotions, symbolic predispositions, and perceptions, achieving durable peace settlement requires reconciliation initiatives and regulation strategies that directly and unapologetically incorporate and address these neglected “immaterial” and “irrational” forces.

    Decolonizing the Criminal Question (2023)
    Oxford University Press
    Details
    Publication Date: 2024-03-29
    Description: This collection engages with debates within ‘criminology’ about matters of colonial power, which have come to be conceptualized through the language of ‘decolonization’. It explores the uneasy relationship between the ‘criminal question’ and colonialism, and foregrounds the relevance of the legacies of this relationship to criminological enquiries. It invites and seeks to pursue a better understanding of the links between imperialism and colonialism on the one hand, and nationalism and globalization on the other, by exposing the imprints of these links on processes of marginalization, racialization, and exclusion that are central to contemporary criminal justice practices within and beyond nation-states. It advances this objective by examining the reverberations of colonial history and logics in the operation of crime control. The volume also aims to explore the critical potential of criminological scholarship, as a field that sits at the margins of several disciplines and perspectives, through a direct engagement with Southern epistemologies and perspectives. To do so, it brings together established and emerging scholars from the humanities and social sciences, who work at the intersections of criminal justice and postcolonial studies.

    Medicine in an Age of Revolution (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-02
    Description: This work is the first major attempt since the 1970s to challenge the idea that the essential engine of medical (and scientific) change in seventeenth-century Britain emanated from puritanism. It seeks to reaffirm the crucial role of the period of the civil wars and their aftermath in providing the most congenial context for a re-evaluation of traditional attitudes to medicine. In the process, it rejects the idea that such initiatives were the special preserve of a small religious elite (puritans), claiming instead that enthusiasm for change can be found across the religious spectrum. At the same time, the work demonstrates that medical practitioners were increasingly drawn into contemporary religious and political debates in a way that led to a fundamental politicization of the ‘profession’. By the end of the seventeenth century, it was now commonplace to see doctors, apothecaries and surgeons fully engaged in everyday political and civic life. At the same time, religious and political orientation often became an important factor in the career development of medics, especially in towns and cities, where substantial benefits might accrue to those who found themselves in favour with the ruling elites, be they Whig or Tory. The body politic, a Renaissance commonplace, was now peopled by medical practitioners who often claimed a special authority when it came to diagnosing the ills of late seventeenth-century society.

    The Developer's Dilemma (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-16
    Description: This book explores this developer’s dilemma or ‘Kuznetsian tension’ between structural transformation and income inequality. Developing countries are seeking economic development—that is, structural transformation—which is inclusive in the sense that it is broad-based and raises the income of all, especially the poor. Thus, inclusive economic growth requires steady, or even falling, income inequality if it is to maximize the growth of incomes at the lower end of the distribution. Yet, this is at odds with Simon Kuznets hypothesis that economic development tends to put upward pressure on income inequality, at least initially and in the absence of countervailing policies. The book asks: what are the types or ‘varieties’ of structural transformation that have been experienced in developing countries? What inequality dynamics are associated with each variety of structural transformation? And what policies have been utilized to manage trade-offs between structural transformation, income inequality, and inclusive growth? The book answers these questions using a comparative case study approach, contrasting nine developing countries while employing a common analytical framework and a set of common datasets across the case studies. The intended intellectual contribution of the book is to provide a comparative analysis of the relationship between structural transformation, income inequality, and inclusive growth; to do so empirically at a regional and national level; and to draw conclusions from the cases on the varieties of structural transformation, their inequality dynamics, and the policies that have been employed to mediate the developer’s dilemma.

    Driving Digital Transformation (2023)
    Oxford University Press
    Details
    Publication Date: 2024-03-30
    Description: This book traces the experience of digital economic transformation in seven developing countries, providing insights for policymakers and practitioners in similar situations as well as lessons for outsiders trying to support government reform efforts more broadly. In one country, the prime minister pushes for the liberalization of digital finance as a central pillar of the country’s national strategy, while the central bank almost makes it a criminal offence. In another, the digital minister tries to scupper the very process to support digital transformation that the president has asked them to co-lead. This book gives a ringside seat on seven developing countries’ tumultuous early steps on the path to a reform of the economy and the government using technology. Written by a group of academics and practitioners from Oxford at the heart of the process, but foregrounding the voices of the policymakers and participants, this book documents and critically assesses efforts to assist a set of governments to kick-start digital transformation. In doing so, it offers lessons for policymakers in other countries. But beyond that, it is an exposition of the process of policymaking more generally in the 2020s, and offers a broader insight as to how outsiders can play a sensible role in other reform processes in developing and emerging countries.

    The Typological Diversity of Morphomes (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-07
    Description: This book constitutes the first typologically oriented monograph on morphomes, which is the term given to systematic morphological identities, usually within inflectional paradigms, that do not map onto syntactic or semantic natural classes like ‘plural’, ‘past’, ‘third-person singular’. Its first half addresses the theoretical and empirical challenges surrounding the identification and definition of morphomes, and surveys their links with related notions like syncretism, homophony, blocking, segmentation, economy, morphophonology, etc. It also presents the different ways in which morphomic structures have been observed to emerge, change, and disappear from a language. The second part of the book contains its core contribution: a database with 120 morphomes across 79 languages from all around the world. These structures are first presented in painstaking philological detail, and then deconstructed into logically independent axes of variation, identified in the spirit of Multivariate Typology. Statistical analysis is then undertaken to spot trends and correlations which are subsequently discussed. Various findings, relevant to both proponents and detractors of Autonomous Morphology, have emerged regarding, for example, the idiosyncratic (i.e. not representative) nature of Romance morphomes, the existence of cross-linguistically recurrent unnatural patterns, and the preference for more natural structures even among morphomes. The database is also expected to allow explorations of other issues, such as how learnability and communicative efficiency pressures impact morphological structure, and lexical and grammatical informativity across the word.

    Details
    Publication Date: 2024-04-04
    Description: Conceptual engineering is a branch of philosophy that is concerned with assessing representational devices such as concepts and words. Conceptual engineers looks for the problems with such devices and attempt to come up with ways of improving flawed concepts: they attempt to say how those concepts should be. This is the first volume devoted entirely to the possibility, benefits, problems, and applications of conceptual engineering and conceptual ethics. It consists of twenty chapters; some advocate for the field, while others develop sceptical arguments, and some focus on the various methodological issues that arise while others apply the method to issues in metaphysics, epistemology, ethics, and social and political philosophy.

    Facing Authority (2023)
    Oxford University Press
    Details
    Publication Date: 2023-12-23
    Description: When your friends call on you to take to the streets and demand the fall of the regime, this presses a practical predicament that we all address, often implicitly, in our everyday lives: Is this regime legitimate? Facing Authority investigates the ways in which this question of legitimacy can be addressed in theory and practice, in the face of disagreement and uncertainty. Instead of asking, “What makes authorities legitimate?” in the abstract, it examines how the question of legitimacy manifests itself in practice. How can we distinguish whether a regime is legitimate, or merely purports to be so? And what does it mean to do this well? Facing Authority proposes that judging legitimacy is not a matter of applying moral knowledge, provided by political philosophy, but of engaging in various forms of political contestation—contestation over the representation of power (what is the nature of the regime?), collective selfhood (who am I, and who are we?), and the meaning of events (what happened here—a coup, or a revolution?). These questions constitute the heart of the question of legitimacy, but thus far they have been neglected by theorists of legitimacy. This book offers a new way of thinking about political legitimacy and practical judgment, interweaving philosophical analyses of key concepts (including representation, identity, and temporality) with concrete examples of struggles for legitimacy, from the German Autumn to the Arab Spring. The result is a pragmatist alternative to predominant moralist and realist approaches to legitimacy in political philosophy.

    Law Beyond Israel (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-08
    Description: The Hebrew Bible formulates two sets of law: one for the Israelites and one for the gentile “residents” living in the Holy Land. Law Beyond Israel: From the Bible to the Qur’an argues that these biblical laws for non-Israelites form the historical basis of qur’anic law. The study corroborates its central claim by assessing laws for gentiles in late antique Jewish and especially in Christian legal discourse, pointing to previously underappreciated legal continuity from the Hebrew Bible to the New Testament and from late antique Christianity to nascent Islam. This volume first sketches the legal obligations that the Hebrew Bible imposes on humanity more broadly and, more specifically, on the non-Israelite residents of the Holy Land. It then traces these laws through Second Temple Judaism to the early Jesus movement, illustrating how the biblical laws for residents inform those formulated in the Acts of the Apostles. Building on this legal continuity, the study employs detailed historical and literary analyses of legal narratives in order to make three propositions. First, rabbinic laws for gentiles, the so-called Noahide Laws, while offering a more lenient interpretation than the one we find in Acts, are equally based on the biblical laws for gentile residents of the Holy Land. Second, Christians generally appreciated and even expanded the gentile laws of Acts. Third, the Qur’an remakes traditional Arabian religious practice by formulating its own distinctive approach to the biblical laws for gentiles, in close continuity with—and at times in critical distance from—late antique Jewish and especially Christian gentile law.

    An Introduction to Particle Accelerators (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-05
    Description: Many scientists and engineers spend their lives designing, constructing, and running accelerators, yet few universities include a study of them in their curricula. This book is a straightforward introduction used by undergraduates and postgraduate students as well as by professional staff attending the summer schools run by the big accelerator laboratories. Research physicists should read it for important background. It covers the essentials of the subject for accelerator physicists and engineers, and is at the level of the introductory courses provided by the CERN and US Accelerator schools. Its style is to give enough information to understand the subject without an excess of mathematics or theory. The text includes exercises and answers to focus the attention of the reader on the calculations necessary to design a new machine. After a chapter on the history of the accelerators, four chapters cover the dynamics of particle beams as they are guided and focused by the magnets of a synchrotron or storage ring and as they are accelerated by rf cavities. Another two chapters cover linear and non-linear effects from imperfect fields. There are chapters on synchrotron radiation, colliders, instabilities, and on future acceleration techniques. A chapter describes the applications of the ten thousand or more accelerators in the world ranging from the linear accelerators used for cancer therapy, through those used in industry and in other fields of research, to the giant ‘atom smashers’ at international particle physics laboratories. A final chapter is to stimulate new ideas for future acceleration techniques.

    A Handbook for Wellbeing Policy-Making (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-05
    Description: Around the world, governments are starting to directly measure the subjective wellbeing of their citizens and to use it for policy evaluation and appraisal. What would happen if a country were to move from using GDP to using subjective wellbeing as the primary metric for measuring economic and societal progress? Would policy priorities change? Would we continue to care about economic growth? What role would different government institutions play in such a scenario? And, most importantly, how could this be implemented in daily practice, for example in policy evaluations and appraisals of government analysts, or in political agenda-setting at the top level? This book provides answers to these questions from a conceptual to a technical level by showing how direct measures of subjective wellbeing can be used for policy evaluation and appraisal, either complementary in the short run or even entirely in the long run. It gives a brief history of the idea that governments should care about the happiness of their citizens, provides theories, makes suggestions for direct measurement, derives technical standards, shows how to conduct wellbeing cost-effectiveness and cost-benefit analyses, and gives examples of how real-world policy evaluations and appraisals would change if they were based on subjective wellbeing. In doing so, the book serves the growing interest of governments as well as non-governmental and international organizations in how to put subjective wellbeing metrics into policy practice.

    Description: Although the global food system increasingly is viewed as unsustainable for human and planetary health, the policy pathways for transforming the status quo are often highly contentious. This book brings together inter-disciplinary scholars to analyze the political economy dynamics central to food system transformation and to identify pathways for enhancing the political feasibility of necessary reforms. Drawing on original surveys, interviews, empirical modeling, and case studies from around the world, the book delves into the power dynamics, interest group coalitions, narratives, and institutional structures that shape decisions related to agricultural productivity, agro-industry, trade, and food consumption.

    The Politics of Bad Options (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-03
    Description: Why did the Eurozone crisis prove to be so difficult to resolve? Why was it resolved in a manner in which some countries bore a much larger share of the pain than other countries? Why did no country leave the Eurozone rather than implement unprecedented austerity? Who supported and who opposed the different policy options in the crisis domestically, and how did the distributive struggles among these groups shape crisis politics? Building on macro-level statistical data, original survey data from interest groups, and qualitative comparative case studies, this book argues and shows that the answers to these questions revolve around distributive struggles about how the costs of the Eurozone crisis should be divided among countries, and among different socioeconomic groups within countries. Together with divergent but strongly held ideas about the “right way” to conduct economic policy and asymmetries in the distribution of power among actors, severe distributive concerns of important actors lie at the root of the difficulties of resolving the Eurozone crisis as well as the difficulties to substantially reform European Monetary Union (EMU). The book provides new insights into the politics of the Eurozone crisis by emphasizing three perspectives that have received scant attention in existing research: A comparative perspective on the Eurozone crisis by systematically comparing it to previous financial crises, an analysis of the whole range of policy options, including the ones not chosen, and a unified framework that examines crisis politics not just in deficit-debtor, but also in surplus-creditor countries.

    Details
    Publication Date: 2024-04-05
    Description: Spin glasses are magnetic materials with strong disorder. Statistical mechanics has been a powerful tool to theoretically analyse various unique properties of spin glasses. A number of new analytical techniques have been developed to establish a theory of spin glasses. Surprisingly, these techniques have offered new tools and viewpoints for the understanding of information processing problems, including neural networks, error-correcting codes, image restoration, and optimization problems. A vast, interdisciplinary field has consequently been developing between physics and information, or more specifically, between the statistical physics of spin glasses and several important aspects of information processing tasks. This book provides a broad overview of this new field. It also contains detailed descriptions of the theory of spin glasses.

    Ancient Traditions of the Virgin Mary's Dormition and Assumption (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-08
    Description: The ancient Dormition and Assumption traditions, a remarkably diverse collection of narratives recounting the end of the Virgin Mary's life, first emerge into historical view from an uncertain past during the fifth and sixth centuries. Initially appearing in Syria, Palestine, and Egypt, these legends spread rapidly throughout the Christian world, resulting in over 60 different narratives from before the tenth century preserved in nine ancient languages. This study presents a detailed analysis of the earliest traditions of Mary's death, including the evidence of the earliest Marian liturgical traditions and related archaeological evidence as well as the numerous narrative sources. Most of the early narratives belong to one of several distinctive literary families, whose members bear evidence of close textual relations. Many previous scholars have attempted to arrange the different narrative types in a developmental typology, according to which the story of Mary's death was transformed to reflect various developments in early Christian Mariology. Nevertheless, evidence to support these theories is wanting, and the present state of our knowledge suggests that the narrative diversity of the early Dormition traditions arose from several independent ‘origins’ rather than through ordered evolution from a single original type. Likewise, scholars have often asserted a connection between the origin of the Dormition traditions and resistance to the council of Chalcedon, but the traditions themselves make this an extremely unlikely proposal. While most of the traditions cannot be dated much before the fifth century, a few of the narratives were almost certainly in composed by the third century, if not even earlier. These narratives in particular bear evidence of contact with gnostic Christianity. Several of the most important narratives are translated in appendices, most appearing in English for the first time.

    The Truth About Denial (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-08
    Description: It is a striking—yet all too familiar—fact about human beings that our belief-forming processes can be so distorted by fears, desires, and prejudices that an otherwise sensible person may sincerely uphold false claims about the world in the face of overwhelming evidence to the contrary. When we describe someone as being “in denial,” we mean that he or she is personally, emotionally threatened by some situation—and consequently has failed to assess the situation properly according to the evidence. People in denial engage in motivated reasoning about their situation: They (sincerely) argue and interpret evidence in light of a preestablished conclusion. One significant type of reason-distorting emotional threat is a threat to one’s ideological worldview. When group interests, creeds, or dogmas are threatened by unwelcome factual information, biased thinking becomes ideological denialism. (One critical example of such denialism is the widespread denial of settled climate science.) Denial can stand in the way of individual well-being, and ideological denialism can stand in the way of good public policy. This book is a wide-ranging examination of denial and denialism. It offers a readable overview of the social psychology of denial, and examines the role of ideological denialism in conflicts over public policy, politics, and culture. Chapters focus on our philosophical and scientific understanding of denial, denial of scientific consensus, denialism in political economy, and denialism in religious belief. An afterword examines proposals for improving science communication in light of findings about motivated reasoning and denial.

    The Many Paths of Change in International Law (2023)
    Oxford University Press
    Details
    Publication Date: 2024-03-30
    Description: How does international law change? How does it adapt to meet global challenges in an accelerated social and political context? The question is crucial for any account of international law, but it is not very well understood. This interdisciplinary volume traces drivers, conditions, and consequences of change across the different fields of international law and paints a complex and varied picture very much in contrast with the relatively static and uniform imagery in most existing accounts. It highlights the social dynamics through which different areas and institutional contexts have generated their own pathways, with different constellations of actors and authorities that condition how smoothly and speedily change proceeds. The volume presents a theoretical framework for understanding this dynamism, and its chapters explore the strategies, forms, and forces behind the many paths of change they encounter. They take into view the politics of precedent and legal restatements, they look at populist and authoritarian challenges and their effects, and they trace change in response to contestation and non-compliance. They also highlight how states are at times marginalized in change processes—and how change may take other forms when international law itself proves too inflexible. Overall, the volume offers a fascinating account of an international legal order in flux—with a degree of dynamism not captured through traditional doctrinal lenses—and helps situate change processes and their varied implications in international law and politics.

    Elements of Phase Transitions and Critical Phenomena (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-05
    Description: Phase transitions and critical phenomena have consistently been among the principal subjects of active studies in statistical physics. The simple act of transforming one state of matter or phase into another, for instance by changing the temperature, has always captivated the curious mind. This book provides an introductory account on the theory of phase transitions and critical phenomena, a subject now recognized to be indispensable for students and researchers from many fields of physics and related disciplines. The first five chapters are very basic and quintessential, and cover standard topics such as mean-field theories, the renormalization group and scaling, universality, and statistical field theory methods. The remaining chapters develop more advanced concepts, including conformal field theory, the Kosterlitz-Thouless transition, the effects of randomness, percolation, exactly solvable models, series expansions, duality transformations, and numerical techniques. Moreover, a comprehensive series of appendices expand and clarify several issues not developed in the main text. The important role played by symmetry and topology in understanding the competition between phases and the resulting emergent collective behaviour, giving rise to rigidity and soft elementary excitations, is stressed throughout the book. Serious attempts have been directed toward a self-contained modular approach so that the reader does not have to refer to other sources for supplementary information. Accordingly, most of the concepts and calculations are described in detail, sometimes with additional/auxiliary descriptions given in appendices and exercises. The latter are presented as the topics develop with solutions found at the end of the book, thus giving the text a self-learning character.

    The Rules of Rescue (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-08
    Description: This is a book about duties to help others. When does one have to sacrifice life and limb, time and money, to prevent harm to others? When must one save more people rather than fewer? These questions arise in emergencies involving nearby strangers who are drowning or trapped in burning buildings. But they also arise in everyday life, in which one has constant opportunities to give time or money to help distant strangers in need of food, shelter, or medical care. With the resources available, one can provide more help or less. This book argues that it is often wrong to provide less help rather than more, even when the personal sacrifice involved makes it permissible not to help at all. It shows that helping distant strangers by donating or volunteering is morally more like rescuing nearby strangers than most of us realize. The ubiquity of opportunities to help others threatens to make morality extremely demanding, and the book argues that it is only thanks to adequate permissions grounded in considerations of cost and autonomy that one may pursue one’s own plans and projects. It concludes that many are required to provide no less help over their lives than they would have done if they were effective altruists.

    Literature and the Senses (2023)
    Oxford University Press
    Details
    Publication Date: 2024-03-27
    Description: Literature and the Senses critically probes the role of literature in capturing and scrutinizing sensory perception. Organized around the five traditional senses, followed by a section on multisensoriality, the collection facilitates a dialogue between scholars working on literature written from the Middle Ages to the present day. The contributors engage with a variety of theorists from Maurice Merleau-Ponty to Michel Serres to Jean-Luc Nancy to foreground the distinctive means by which literary texts engage with, open up, or make uncertain dominant views of the nature of perception. Considering the ways in which literary texts intersect with and diverge from scientific, epistemological, and philosophical perspectives, these essays explore a wide variety of literary moments of sensation including the interspecies exchange of a look between a swan and a young Indigenous Australian girl; the sound of bees as captured in an early modern poem; the noxious smell of the ‘Great Stink’ that recurs in the Victorian novel; the taste of an aubergine registered in a poetic performance; tactile gestures in medieval romance; and the representation of a world in which the interdependence of human beings with the purple hibiscus plant is experienced through all five senses. The collection builds upon and breaks new ground in the field of sensory studies, focusing on what makes literature especially suitable to engaging with, contributing to, and challenging our perennial understandings of the senses.

    Electron-Phonon Interactions in Low-Dimensional Structures (2023)
    Oxford University Press
    Details
    Publication Date: 2024-04-05
    Description: The study of electrons and holes confined to two, one, and even zero dimensions has uncovered a rich variety of new physics and applications. This book describes the interaction between these confined carriers and the optic and acoustic phonons within and around the confined regions. Phonons provide the principal channel of energy transfer between the carriers and their surroundings and also the main restriction to their room temperature mobility. However, they also have many other roles; they contribute, for example, an essential feature to the operation of the quantum cascade laser. Since their momenta at relevant energies are well matched to those of electrons, they can also be used to probe electronic properties such as the confinement width of two-dimensional (2-D) electron gases and the dispersion curve of quasiparticles in the fractional quantum Hall effect. The book describes both the physics of the electron-phonon interaction in the different confined systems and the experimental and theoretical techniques that have been used in its investigation. The experimental methods include optical and transport techniques as well as techniques in which phonons are used as the experimental probe. This book provides an up-to-date review of the physics and its significance in device performance.

    Immaculate Sounds (2023)
    Oxford University Press
    Details
    Publication Date: 2024-03-24
    Description: In Catholic doctrine, the Immaculate Conception of the Virgin Mary is the belief that Mary, the mother of Christ, was exempt from original sin from the moment of her conception, and thereby a co-redeemer alongside her son. Praise for this complicated devotion took place in Europe throughout the medieval period and resounded in the Americas with the founding of the first convent in Mexico City under the Order of the Immaculate Conception in 1540. All other orders of nuns in New Spain branched out from this convent, spreading the Marian devotion throughout the region. In this book, author Cesar D. Favila argues that the sonification of virginity and the Virgin Mary was fundamental to the promotion of the Immaculate Conception doctrine, and that this was part of a complex network of sonified practices in the lives of New Spanish nuns. These ""immaculate sounds,"" a term Favila uses for the cloistered nuns' idealized vocalizations as well as the expression of doctrinal rhetoric through musical metaphors, echoed the highly regulated realm of the convent and played a pivotal role in mediating between the lives of New Spanish nuns and the expectation that they would save the secular world with their vocalized prayers. In addition to the sonification of discipline, Favila shows that immaculate sounds also enhanced the nuns' engagement with their religious practices and facilitated embodied and spiritual engagement with Catholic doctrines. Throughout his study, he delves into rarely studied music sources from seventeenth- and eighteenth-century New Spain alongside the rulebooks, devotional literature, and nuns' biographies that regulated convent life and inspired nuns' hymns. In doing so, Favila brings together a narrative of salvation that shines a light on the musical lives of nuns and locates women's agency within a hierarchical society that silenced some women and required others to sing.

    Publication Date: 2024-04-06
    Description: This book presents 23 in-depth case studies of successful public policies and programmes in Sweden, Denmark, Finland, Norway and Iceland. Each chapter tells the story of the policy’s origins, aims, design, decision-making and implementation processes, and assesses in which respects—programmatically, process-wise, politically and over time—and to what extent it can be considered a policy success. It also points towards the driving forces of success, and the challenges that have had to be overcome to achieve it. Combined, the chapters provide a resource for policy evaluation researchers, educators and students of public policy and public administration, both within and beyond the Nordic region.

    Controlling the Capital (2023)
    Oxford University Press
    Details
    Publication Date: 2024-03-30
    Description: Authoritarianism is on the rise globally, with more than twice as many countries experiencing democratic decline as democratic enhancement in recent years. This has been occurring simultaneously with unprecedented rates of urbanization in many parts of the world, raising questions about the role of cities—often considered the focal points of democratic deepening—in this authoritarian turn. With most literature on authoritarianism focusing on the national scale, in this book we train our gaze on capital cities, which as ‘containers’ of both capital and sovereignty are spaces in which authoritarian dominance is increasingly built, contested, maintained, and undone. Focusing on some of the world’s fastest urbanizing regions in sub-Saharan Africa and South Asia, the book explores the multiple ways in which authoritarian regimes have been attempting to build and sustain long-term dominance in capital cities in order to meet the challenge of urban political resistance. Our diverse selection of case studies spans governing regimes that have recently tried to build urban dominance and spectacularly failed, as well as those that have managed to hold onto power by constantly evolving strategies for dominance that limit the potential for urban opposition to tip into regime overthrow. With chapters on Addis Ababa, Colombo, Dhaka, Harare, Kampala, and Lusaka, this book offers the first cross-regional comparative study of the relationship between cities and political dominance. It contributes to debates on authoritarianism and authoritarian durability, urbanization, political contestation and resistance, the politics of development, and the prospects for democracy.

    Tasks, Skills, and Institutions (2023)

    Details
    Publication Date: 2024-03-30
    Description: This book provides a unique, comparative assessment on how the nature of work is changing in 11 major developing countries, and the role that these changes play in shaping earnings inequality in these societies. It provides a nuanced and context-sensitive developing-country perspective with an in-depth assessment of national trends in earnings inequality, which are assessed against changes in the supply of higher skilled workers and education premia, on the one hand, and changes in the occupational structure and the remuneration of tasks, on the other, while being mindful of broader macroeconomic trends and institutional developments. We start showing that the common assumption that occupations are identical around the world tends to lead to an overestimation of the non-routine task content of jobs in developing and emerging economies. Then, we use country-specific measures of routine-task intensity, along with the standard O*NET measures, and other innovative ways to push the boundaries of existing research and make the most of the limited information that is available in each of the countries under study. We show that the large changes in the composition of workers by education and job routine-task intensity, which developing countries exhibited in the 2000s and 2010s, generally contributed to higher inequality, ceteris paribus. We also find evidence of job polarization or widening of earnings inequality driven by the evolution of routine intensity of jobs in several cases. However, changes in the education premium, along institutional factors, seem to explain inequality trends to a larger extent.

    New Mediums, Better Messages? (2023)

    Details
    Publication Date: 2023-08-17
    Description: The notion of development influences and is influenced by all aspects of human life. Social science is but one representational option among many for conveying the myriad ways in which development is conceived, encountered, experienced, justified, courted, and/or resisted by different groups at particular times and places. As international development has become more quantitative and economics-centred, there is an enduring sense that what is measured (and thus 'valued' and prioritized) may have become too narrow, that the powers of prediction claimed by some areas of economics and management may have overreached, and that the human dimension is in danger of being lost. Reflecting this concern, New Mediums, Better Messages? contributes to new conversations between science, social science, and the humanities around the roles of different kinds of knowledge, stories, and data play in relation to global development. It brings together a team of multidisciplinary contributors to explore popular representions of development, including music, blogs, and fiction.
