    Description: Mass mortality events (MMEs) are defined as the death of large numbers of fish over a short period of time. These events can result in catastrophic losses to the Atlantic salmon aquaculture industry and the local economy. However, they are challenging to understand because of their relative infrequency and the high number of potential factors involved. As a result, the causes and consequences of MMEs in Atlantic salmon aquaculture are not well understood. In this study, we developed a structural network of causal risk factors for MMEs for aquaculture and the communities that depend on Atlantic salmon aquaculture. Using the Interpretive Structural Modeling (ISM) technique, we analysed the causes of Atlantic salmon mass mortalities due to environmental (abiotic), biological (biotic) and nutritional risk factors. The consequences of MMEs were also assessed for the occupational health and safety of aquaculture workers and their implications for the livelihoods of local communities. This structural network deepens our understanding of MMEs and points to management actions and interventions that can help mitigate mass mortalities. MMEs are typically not the result of a single risk factor but are caused by the systematic interaction of risk factors related to the environment, fish diseases, feeding/nutrition and cage-site management. Results also indicate that considerations of health and safety risk, through pre- and post-event risk assessments, may help to minimize workplace injuries and eliminate potential risks of human fatalities. Company and government assisted socio-economic measures could help mitigate post-mass mortality impacts. Appropriate and timely management actions may help reduce MMEs at Atlantic salmon cage sites and minimize the physical and social vulnerabilities of workers and local communities.

    Fabric controls fault stability in serpentinite gouges (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-09
    Description: Serpentinites are polymineralic rocks distributed almost ubiquitously across the globe in active tectonic regions. Magnetite-rich serpentinites are found in the low-strain domains of serpen- tinite shear zones, which act as potential sites of nucleation of unstable slip. To assess the potential of earthquake nucleation in these materials, we investigate the link between me- chanical properties and fabric of these rocks through a suite of laboratory shear experiments. Our experiments were done at room temperature and cover a range of normal stress and slip velocity from 25 to 100 MPa and 0.3 to 300 μm s −1 , respecti vel y. We show that magnetite-rich serpentinites are ideal materials since they display strong sensitivity to the loading rate and are susceptible to nucleation of unstable slip, especially at low forcing slip velocities. We also aim at the integration of mechanical and microstructural results to describe the underlying mechanisms that produce the macroscopic behaviour. We show that mineralogical composi- tion and mineral structure dictates the coexistence of two deformation mechanisms leading to stable and unstable slip. The weakness of phyllosilicates allows for creep during the interseis- mic phase of the laboratory seismic cycle while favouring the restoration of a load-bearing granular framework, responsible of the nucleation of unstable events. During dynamic slip, fault zone shear fabric determines the mode of slip, producing either asymmetric or Gaussian slip time functions for either fast or slow events. We report rate/state friction parameters and integrate our mechanical data with microstructural observations to shed light on the mech- anisms dictating the complexity of laborator y ear thquakes. We show that mineralogical and fabric heterogeneities control fault slip behaviour.

    New constraints on the shear wave velocity structure of the Ivrea geophysical body from seismic ambient noise tomography (Ivrea-Verbano Zone, Alps) (2024)
    Oxford University Press
    Details
    Publication Date: 2024-01-19
    Description: We performed seismic ambient noise tomography to investigate the shallow crustal structure around the Ivrea geophysical body (IGB) in the Ivrea-Verbano Zone (IVZ). We achieved higher resolution with respect to previous tomographic works covering the Western Alps, by processing seismic data collected by both permanent and temporary seismic networks (61 broad-band seismic stations in total). This included IvreaArray, a temporary, passive seismic experiment designed to investigate the IVZ crustal structure. Starting from continuous seismic ambient noise recordings, we measured and inverted the dispersion of the group velocity of surface Rayleigh waves (fundamental mode) in the period range 4–25 s. We obtained a new, 3-D vS model of the IVZ crust via the stochastic neighbourhood algorithm (NA), with the highest resolution between 3 to 40 km depth. The fast and shallow shear wave velocity anomaly associated with the IGB presents velocities of 3.6 km s−1 directly at the surface, in remarkable agreement with the location of the exposed lower-to-middle crustal and mantle outcrops. This suggests a continuity between the surface geological observations and the subsurface geophysical anomalies. The fast IGB structure reaches vS of 4 km s−1 at 20–25 km depth, at the boundary between the European and Adriatic tectonic plates, and in correspondence with the earlier identified Moho jump in the same area. The interpretation of a very shallow reaching IGB is further supported by the comparison of our new results with recent geophysical investigations, based on receiver functions and gravity anomaly data. By combining the new geophysical constraints and the geological observations at the surface, we provide a new structural interpretation of the IGB, which features lower crustal and mantle rocks at upper crustal depths. The comparison of the obtained vS values with the physical properties from laboratory analysis of local rock samples suggests that the bulk of the IGB consists of a combination of mantle peridotite, ultramafic and lower crustal rocks, bound in a heterogeneous structure. These new findings, based on vS tomography, corroborate the recent interpretation for which the Balmuccia peridotite outcrops are continuously linked to the IGB structure beneath. The new outcomes contribute to a multidisciplinary framework for the interpretation of the forthcoming results of the scientific drilling project DIVE. DIVE aims at probing the lower continental crust and its transition to the mantle, with two ongoing and one future boreholes (down to 4 km depth) in the IVZ area, providing new, complementary information on rock structure and composition across scales. In this framework, we constrain the upper crustal IGB geometries and lithology based on new evidence for vS, connecting prior crustal knowledge to recent active seismic investigations.

    Implications for the geometry of plate boundaries in NE Asia based on the geodetic analysis of the 2020Mw 6.4 Koryak event (2024)
    Oxford University Press
    Details
    Publication Date: 2024-01-23
    Description: On the 9th of January 2020, an Mw 6.4 strike-slip earthquake took place north of the Asian margin of the Bering Sea. The earthquake occurred within the known reverse-right-lateral active fault zone, called Khatyrka–Vyvenka, which transverses the Koryak Highland from SE to NW and is thought to be a surface manifestation of the Asian portion of either the Bering plate boundary or the northern edge of the Alaskan stream. No other strong earthquake has ever been recorded in this remote uninhabited area and the few existing seismic stations provide poor quality earthquake locations.We adopt SAR interferometry (InSAR) technique to define an improved location of the Koryak 2020 earthquake and constrain the seismic source. The analysis of the 2020 event revealed a previously unknown active fault of left-lateral kinematics that is possibly hidden and strikes NWtransversely to the Khatyrka–Vyvenka fault zone. Although several mechanisms could account for left-lateral kinematics of this fault, we propose that the structure is part of a more extended NW fault structure, that formed in pre-neotectonic times and has played a role of a pre-existing rheological discontinuity. This revived NW structure together with a similar structure located easterly, so far aseismic, make the plate/stream boundary segmented, step-like in plan view. The step-like boundary geometry may be the result of internal transform deformation of a rigid plate, but it is better explained by deflections of the Alaskan stream edge at local crustal asperities, which are pre-Cenozoic terrains.

    Moment magnitude for earthquakes in the Etna volcano area (2024)
    Oxford University Press
    Details
    Publication Date: 2024-03-19
    Description: Accurate quantification of seismic activity in volcanic regions is an important asset for im- proving hazard and risk assessment. This is especially true for densely populated areas, as in the case of Etna volcano (Southern Italy). There, the volcanic hazard is amplified by the seismic risk of acti ve faults, especiall y on the eastern flank of the volcano. In such a context, it is common to rely on moment magnitude ( M W ) to characterize seismicity and monitor the energy released during an eruption. In this study, we calculate the moment-based magnitude ( M W ) for selected seismic data sets, using different approaches in distinct magnitude ranges to cover the widest possible range of magnitude that characterizes Etna’s seismicity . Specifically , we computed the M W from a data set of moment tensor solutions of earthquakes that occurred in the magnitude range 3.4 ≤M L ≤4.8 during 2005–2020; we created a data set of seismic moment and associated M W for earthquakes 1.0 ≤M L 〈 3.4 obtained by analysing source spectra; we fine-tuned two relationships, for shallow and deep earthquakes, to obtain M W from response spectra. Finally, we calibrated a specific relationship between M W and M L for the Etna area earthquakes in the range 1.0 ≤M L ≤4.8. All the empirical relationships obtained in this study can be applied in real-time analysis of the seismicity to provide fast and robust information on the released seismic energy.

    A statistical framework for detection of b-value anomalies in Italy (2024)
    Oxford University Press
    Details
    Publication Date: 2024-03-12
    Description: This study presents a new robust statistical framework, in which to measure relative differences, or deviations from a hypothetical reference value, of Gutenberg-Richter b-value. Moreover, it applies this method to recent seismicity in Italy, to find possible changes of earthquake magnitude distribution in time and space. The method uses bootstrap techniques, which have no prior assumptions about the distribution of data, keeping their basic features. Excluding Central Italy, no significative b-value variation is found, revealing that the frequency-magnitude distribution exponent is substantially stable or that data are not able to reveal hidden variations. Considering the small size of examined magnitude samples, we cannot definitively decide if the higher b-values in Central Italy, consistently founded by all applied tests, have a physical origin or result from a statistical bias. In any case, they indicate short-lived excursions which have a temporary nature and, therefore, cannot be associated solely to spatial variations in tectonic framework. Both the methodological issues and the results of the application to seismicity in Italy show that a correct assessing of b-value changes requests appropriate statistics, that accurately quantify the low accuracy and precision of b-value estimation for small magnitude samples.

    Description: We present the results from a fully unconstrained moment tensor inversion of induced seismic events in a complex and high seismic hazard region (Val d’Agri basin, Southern Italy). The study area hosts two well-documented cases of induced microseismicity linked to (i) a wastewater injection well of a giant oilfield (the largest in onshore Europe), and (ii) severe seasonal level changes of an artificial lake. In order to gather information on the non-doublecouple components of the source and to better understand the rupture mechanisms, we analyse seismic events recorded during daily injection tests in the disposal well. The computed moment tensors have significant non-double-couple components that correlate with the well-head injection pressure. The injection parameters strongly influence the rupture mechanism that can be interpreted as due to the opening/closing of a fracture network inside a fault zone of a pre-existing thrust fault. For the case of the reservoir-induced seismicity, no direct correlations are observed with the loading/unloading of the reservoir.

    Description: Estimation of local seismic response plays a key role in assessing local seismic hazard and particularly in the design of shaking scenarios. Modelling local seismic response involves knowing of the shear wave velocity (Vs) and quality factor (Qs) profiles for the site in question. The many techniques that have been developed to assess Vs in surface deposits produce reliable measurements of Vs , but these rarely correspond to direct measurements of Qs . The latter is often considered through damping measures from laboratory tests on small-scale soil samples, which can provide information primarily on intrinsic attenuation, neglecting the contribution of scattering effects. In this paper, using seismic recordings obtained at the surface and in boreholes at 100 m depth, we estimate an average value of Qs of some characteristic alluvial deposits of the Po Plain (northern Italy). Data come from a microseismic network which sampled an almost uniform lithology in the central Po Plain and consisted of three surface and four borehole stations with an interstation distance of about 2 km. The average value of Qs of the shallowest 100 m of the sedimentary strata, Qs100, is estimated by considering: (1) the high-frequency attenuation of seismic waves due to propagation through the corresponding stratigraphy and (2) the interference between incident and surface-reflected waves observed at borehole stations. We parametrize the first through k0_100, the difference between the values of the spectral decay parameter kappa (k) estimated at the surface and at the boreholes depth, respectively. We use the second in order to compute Vs100, the time-averaged Vs referred to the uppermost 100 m stratigraphy. We obtain: k0_100 = (11 ± 3) ms, Vs100 = (309 ± 11) m s −1 and Qs100 = 31 ± 10. At the surface, the estimated values of the site-specific kappa, k0, are found to range from 75 to 79 ms. As expected, these results are in good agreement with studies performed in other sites characterized by sandy or clayey lithologies, and can be usefully used in site response analysis at sites where the rigidity is mainly controlled by lithostatic pressure.

    Description: In a recent work, we applied the every earthquake a precursor according to scale (EEPAS) probabilistic model to the pseudo-prospective forecasting of shallow earthquakes with magni- tude M 5.0 in the Italian region. We compared the forecasting performance of EEPAS with that of the epidemic type aftershock sequences (ETAS) forecasting model, using the most recent consistency tests developed within the collaboratory for the study of earthquake predictabil- ity (CSEP). The application of such models for the forecasting of Italian target earthquakes seems to show peculiar characteristics for each of them. In particular, the ETAS model showed higher performance for short-term forecasting, in contrast, the EEPAS model showed higher forecasting performance for the medium/long-term. In this work, we compare the performance of EEPAS and ETAS models with that obtained by a deterministic model based on the occur- rence of strong foreshocks (FORE model) using an alarm-based approach. We apply the two rate-based models (ETAS and EEPAS) estimating the best probability threshold above which we issue an alarm. The model parameters and probability thresholds for issuing the alarms are calibrated on a learning data set from 1990 to 2011 during which 27 target earthquakes have occurred within the analysis region. The pseudo-prospective forecasting performance is as- sessed on a validation data set from 2012 to 2021, which also comprises 27 target earthquakes. Tests to assess the forecasting capability demonstrate that, even if all models outperform a purely random method, which trivially forecast earthquake proportionally to the space–time occupied by alarms, the EEPAS model exhibits lower forecasting performance than ETAS and FORE models. In addition, the relative performance comparison of the three models demonstrates that the forecasting capability of the FORE model appears slightly better than ETAS, but the difference is not statistically significant as it remains within the uncertainty level. However, truly prospective tests are necessary to validate such results, ideally using new testing procedures allowing the analysis of alarm-based models, not yet available within the CSEP.

    Low-strength shear zone in the western Makran subduction zone, southeastern Iran: insights from a receiver function analysis (2024)
    Oxford University Press
    Details
    Publication Date: 2024-05-09
    Description: To understand the seismic hazard of a subduction zone, it is necessary to know the geometry, location and mechanical characteristics of the interplate boundary below which an oceanic plate is thrust downward. By considering the azimuthal dependence of converted P-to-S (Ps) amplitudes in receiver functions, we have detected the interplate boundary in the Makran subduction zone, revealing significant seismic anisotropy at the base of the accretionary wedge above the slab before it bends down beneath the Jaz Murian basin. This anisotropic feature aligns with a zone of reduced seismic velocity and a high primary/secondary wave velocity ratio (Vp/Vs), as documented in previous studies. The presence of this low-velocity highly anisotropic layer at the base of the accretionary wedge, likely representing a low-strength shear zone, could possibly explain the unusually wide accretionary wedge in Makran. Additionally, it may impact the location and width of the locked zone along the interplate boundary.

    Description: The Every Earthquake a Precursor According to Scale (EEPAS) forecasting model is a space– time point-process model based on the precursory scale increase (ψ ) phenomenon and associated predictive scaling relations. It has been previously applied to New Zealand, Cal- ifornia and Japan earthquakes with target magnitude thresholds varying from about 5–7. In all previous application, computations were done using the computer code implemented in Fortran language by the model authors. In this work, we applied it to Italy using a suite of computing codes completely rewritten in Matlab. We first compared the two software codes to ensure the convergence and adequate coincidence between the estimated model parameters for a simple region capable of being analysed by both software codes. Then, using the rewritten codes, we optimized the parameters for a different and more complex polygon of analysis using the Homogenized Instrumental Seismic Catalogue data from 1990 to 2011. We then perform a pseudo-prospective forecasting experiment of Italian earthquakes from 2012 to 2021 with Mw ≥ 5.0 and compare the forecasting skill of EEPAS with those obtained by other time in- dependent (Spatially Uniform Poisson, Spatially Variable Poisson and PPE: Proximity to Past Earthquakes) and time dependent [Epidemic Type Aftershock Sequence (ETAS)] forecasting models using the information gain per active cell. The preference goes to the ETAS model for short time intervals (3 months) and to the EEPAS model for longer time intervals (6 months to 10 yr).

    Hydrological and volcano-related gravity signals at Mt. Somma–Vesuvius from ∼20 yr of time-lapse gravity monitoring: implications for volcano quiescence (2024)

    Description: We report on about 20 yr of relative gravity measurements, acquired on Mt. Somma–Vesuvius volcano in order to investigate the hydrological and volcano-tectonic processes controlling the present-day activity of the volcano. The retrieved long-term field of time gravity change (2003–2022) shows a pattern essentially related to the subsidence, which have affected the central part of the volcano, as detected by the permanent GNSS network and InSAR data. After reducing the observations for the effect of vertical deformation, no significant residuals are found, indicating no significant mass accumulation or loss within the volcanic system. In the north-western sector of the study area, at the border of the volcano edifice, however, significant residual positive gravity changes are detected which are associated to ground-water rebound after years of intense exploitation of the aquifers. On the seasonal timescale, we find that stations within the caldera rim are affected by the seasonal hydrological effects, while the gravity stations at the base of the Vesuvius show a less clear correlation. Furthermore, within the caldera rim a multiyear gravity transient is detected with an increase phase lasting about 4 yr followed by a slower decrease phase. Analysis of rain data seem to exclude a hydrological origin, hence, we hypothesize a deeper source related to the geothermal activity, which can be present even if the volcano is in a quiescent state. We infer the depth and volume of the source by inverting the spatial pattern of the gravity field at the peak of the transient. A volume of fluids of 9.5 × 107 m3 with density of 1000 kg m−3 at 2.3 km depth is capable to fit reasonably well the observations. To explain the gravity transient, simple synthetic models are produced, that simulate the ascent of fluids from a deep reservoir up to the depth of 2.3 km and a successive diffusion within the carbonate aquifer hosting the geothermal system. The whole process appears to not significantly affect the seismicity rate and the deformation of the volcano. This study demonstrates the importance of a 4-D gravity monitoring of a volcano to understand its complex gravity signals that cover different spatial and temporal scales. Discriminating the different contributions that mix up in the observed gravity changes, in particular those due to hydrologic/anthropogenic activities form those due to the geothermal dynamics, is fundamental for a complete and reliable evaluation of the volcano state.

    Publication Date: 2024-04-11
    Description: This dataset reports measurements from a laboratory incubation of soils sourced from a boreal peatland and surrounding habitats (Siikaneva Bog, Finland). In August 2021, soil cores were collected from three habitat zones: a well-drained upland forest, an intermediate margin ecotone, and a Sphagnum moss bog. The cores from each habitat were taken from surface to approximately 50cm below surface using an Eijelkamp peat corer and subdivided by soil horizon. The samples were then incubated anaerobically for 140 days in three temperature treatment groups (0, 4, 20°C). Subsamples of the incubations headspace (250 µL) were measured on a gas chromatograph (7890A, Agilent Technologies, USA) with flame ionization detection (FID) for CO2 and CH4 concentrations. The rate of respiration from the samples were calculated per gram carbon and per gram soil as described in the method of Robertson., et al. (1999) and reported here, along with other relevant parameters.

    An Amphibole Perspective on the Recent Magmatic Evolution of Mount St. Helens (2024)
    Oxford University Press
    Details
    Publication Date: 2024-02-23
    Description: Compositional variations of amphibole stratigraphically recovered from multiple eruptions at a given volcano have a great potential to archive long-term magmatic processes in its crustal plumbing system. Calcic amphibole is a ubiquitous yet chemically and texturally diverse mineral at Mount St. Helens (MSH), where it occurs in dacites and in co-magmatic enclaves throughout the Spirit Lake stage (last ~4000 years of eruptive history). It forms three populations with distinct geochemical trends in key major and trace elements, which are subdivided into a high-Al (11–14.5 wt% Al2O3), a medium-Al (10–12.5 wt% Al2O3), and a low-Al (7.5–10 wt% Al2O3) amphibole population. The oldest investigated tephra record (Smith Creek period, 3900–3300 years BP) yields a bimodal amphibole distribution in which lower-crustal, high-Al amphibole cores (crystallized dominantly from basaltic andesite to andesite melts) and upper-crustal, low-Al amphibole rims (crystallized from rhyolitic melt) document occasional recharge of a shallow silicic mush by a more mafic melt from a lower-crustal reservoir. The sudden appearance of medium-Al amphiboles enriched in incompatible trace elements in eruptive periods younger than 2900 years BP is associated with a change in reservoir conditions toward hotter and drier magmas, which indicates recharge of the shallow silicic reservoir by basaltic melt enriched in incompatible elements. Deep-crystallizing, high-Al amphibole, however, appears mostly unaffected by such incompatible-element-enriched basaltic recharge, suggesting that these basalts bypass the lower crustal reservoir. This could be the result of the eastward offset position of the lower crustal reservoir relative to the upper crustal storage zone underneath the MSH edifice. Amphibole has proven to be a sensitive geochemical archive for uncovering storage conditions of magmas at MSH. In agreement with geophysical observations, storage and differentiation have occurred in two main zones: an upper crustal and lower crustal reservoir (the lower one being chemically less evolved). The upper crustal silicic reservoir, offset to the west of the lower crustal reservoir, has captured compositionally unusual mafic recharge (drier, hotter, and enriched in incompatible trace elements in comparison to the typical parental magmas in the region), resulting in an increased chemical diversity of amphiboles and their carrier intermediate magmas, in the last ~3000 years of MSH’s volcanic record.

    Plankton community changes during the last 124 000 years in the subarctic Bering Sea derived from sedimentary ancient DNA (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-05
    Description: Current global warming results in rising sea-water temperatures, and the loss of sea ice in arctic and subarctic oceans impacts the community composition of primary producers with cascading effects on the food web and potentially on carbon export rates. This study analyzes metagenomic shotgun and diatom rbcL amplicon-sequencing data from sedimentary ancient DNA (sedaDNA) of the subarctic western Bering Sea that records phyto- and zooplankton community changes over the last glacial–interglacial cycle, including the last interglacial period (Eemian). Our data show that interglacial and glacial plankton communities differ, with distinct Eemian and Holocene plankton communities. The generally warm Holocene period is dominated by pico-sized cyanobacteria and bacteria-feeding heterotrophic protists, while the Eemian period is dominated by eukaryotic pico-sized chlorophytes and Triparmaceae. In contrast, the glacial period is characterized by micro-sized phototrophic protists, including sea-ice associated diatoms in the family Bacillariaceae and co-occurring diatom-feeding crustaceous zooplankton. Our deep-time record of plankton community changes reveals a long-term decrease in phytoplankton cell size coeval with increasing temperatures, and resembling community changes in the currently warming Bering Sea. The phytoplankton community in the warmer-than-present Eemian period is distinct from modern communities and limits the use of the Eemian as an analog for future climate scenarios. However, under enhanced future warming, the expected shift towards the dominance of small-sized phytoplankton and heterotrophic protists might result in an increased productivity, whereas the community’s potential of carbon export will be decreased, thereby weakening the subarctic Bering Sea’s function as an effective carbon sink.

    Zooplankton seasonal vertical migration in an optimality-based plankton ecosystem model (2024)
    Oxford University Press
    Details
    Publication Date: 2024-05-06
    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.

    Towards a Vigilant Society (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-11
    Description: Towards a Vigilant Society sheds light on the emergence of a new society of vigilance, in particular the actions of anti-migrant groups around Dover and Calais. Based on field research on both sides of the channel, it studies the dynamics of these groups – midway between a social movement and vigilantism – at these two key points in the international migration route between the European Union and the United Kingdom. In recent years, a series of anti-migrant groups have been mobilising on both sides of the Channel to counter migrations. Their actions range from demonstrations, to violence against migrants. And by staging their actions on social media, which is an extraordinary sounding board, these groups can build an online community and a mass audience, influencing public opinion and even the migration policies of states.

    City of Equals (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-06
    Description: When we think about equality in the city, we are very likely to think first of the wide and growing divide between rich and poor, in material terms. Yet when we think more about a 'city of equals' it becomes apparent that how people feel treated by the city and those around them, and whether they can live according to their values, are much more central. Accordingly, combining their own reflections, a multi-disciplinary literature review, and, distinctively, more than 180 interviews in 10 cities in 6 countries, Wolff and de Shalit have derived an account of a city of equals based on the idea that it should give each of its city-zens a secure sense of place or belonging. Four underlying values structure this account. First, access to the goods and services of the city should not be based purely on the market. Second, each person should be able to live a life they find meaningful. Third, there should be diversity and wide social mixing. Fourth, there should be 'non-deferential inclusion': each person should be able to get access to what they are entitled to without being treated as less worthy than others. They should be able to enjoy their rights without bowing and scraping, waiting longer than others, or going through special bureaucratic hurdles. In sum, in a city of equals each person is proud of their city and has the (justified) feeling that their city is proud of (people like) them.

    The Ethics of Surveillance in Times of Emergency (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-08
    Description: The Covid-19 pandemic is arguably the first international emergency of the twenty-first century. In order to respond to this emergency, countries and governments around the world were forced to engage in a range of actions and policies that would not otherwise have been permitted. Looking in particular at the use of surveillance technologies, this book examines the challenge of ethics in emergencies. What can states do to keep their populations safe, what can citizens expect of their governments, and when are those government actions unjustified? By looking at the use of surveillance in times of emergency, this book explores ethical, philosophical, political, and social concepts, challenges them, and offers a set of views on where those concepts may evolve into the future. As a global population, we will be faced with emergencies, and it is possible that these will also be global in their impact. The ethics of surveillance in times of emergency is both of its time, and ongoing; we must learn our lessons from the last emergency, to be prepared for the next ones.

    What Is Structural Injustice? (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-04
    Description: What is Structural Injustice? is the first edited collection to bring together the voices of leading structural injustice scholars from politics, philosophy and law to explore the concept of structural injustice which has now become a central feature of all three disciplines and is considered by many to be a ‘field of study.’ The volume features specially selected original and essential works on structural injustice. The volume provides a range of disciplinary, ontological and epistemological perspectives on what structural injustice is and includes feminist and post-colonial theories to interrogate how structural injustice exacerbates and reproduces existing inequalities and relations of power. This book aims to become a touchstone text for those interested in the different ways we can understand structural injustice, how it manifests, how it relates to other forms of injustice, who is responsible for its redress and the different ways we might go about it. This book will appeal to a wide audience of students, both undergraduate and postgraduate, as well as the general academic population, experts on structural injustice, interested practitioners in politics and members of the public.

    Just Prospering? Plato and the Sophistic Debate about Justice (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-11
    Description: This book argues that Plato’s Republic must be understood as developing out of a 5th Century sophistic debate. In Part One the author presents a new analysis of the sophists and their extant texts addressing the important topics of justice and its value. This part shows that already in the 5th Century there was a robust debate about whether the just or unjust life was better for the self-interested individual, and that multiple sophistic authors made inventive and philosophically sophisticated arguments on both sides of this debate. The Moral Cynics argues that the intelligent individual was better off being unjust, whereas the Friends of Justice defended the idea that the just life was better for human beings. Part Two argues that Plato was very much aware of this debate and that in a number of dialogues—but most importantly in Republic—he engaged with this debate. The immoralist challenge that Glaucon and Adeimantus pose to Socrates early in Republic draws from the arguments of the 5th Century Moral Cynics and moreover identifies problems with the arguments of the 5th Century Friends of Justice. By having Socrates make an argument that overcomes the theoretical weaknesses of the earlier Friends of Justice, Plato is able to pose a new defence of justice that is more effective at responding to the Moral Cynics. The book’s analysis of Republic suggests new readings for certain important passages, such as the division of goods.

    Landscape, Religion, and the Supernatural (2024)
    Oxford University Press
    Details
    Publication Date: 2024-03-19
    Description: Landscape, Religion, and the Supernatural presents a summa of current and classic theorizing on religion and the supernatural in relationship to the land and develops this theorizing further by confronting it with a rich set of folkloristic and historical data. Focusing on the themes of “time and memory,” “repeating patterns,” “identity formation,” “morality,” “labor,” “playfulness and adventure,” “power and subversion,” “sound,” “emotions,” “coping with contingency,” “home and unhomeliness,” and “nature and environment,” the book engages with a broad range of theoretical concepts and approaches from the interdisciplinary field of landscape theory and the study of religions. It brings this theorizing into dialogue with the rich culture of local storytelling and landscape-related traditional beliefs of the Strandir district of the Icelandic Westfjords. In this rural region, landscape-related traditions have been collected since the early nineteenth century and continue to be important to this day. Confronting this rich heritage with the insights of landscape theory both in and beyond the study of religions allows important new contributions to theorizing landscape and religion, especially when it comes to considering the perspectives on landscape held by rural populations rather than the urban upper classes that have stood in the focus of research to date. The example of the Icelandic Westfjords shows the extreme richness of religious and supernatural approaches to the landscape that can be developed in rural communities, and how they are significantly and characteristically different from the urban perspectives of literature and the arts.

    Politics and the Urban Frontier (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-05
    Description: Despite the rise of global technocratic ideals of city-making, cities around the world are not merging into indistinguishable duplicates of one another. In fact, as the world urbanizes, urban formations remain diverse in their socio-economic and spatial characteristics, with varying potential to foster economic development and social justice. This book argues that these differences are primarily rooted in politics, and if we continue to view cities as economic and technological projects to be managed rather than terrains of political bargaining and contestation, the quest for better urban futures is doomed to fail. Dominant critical approaches to urban development tend to explain difference with reference to the variegated impacts of neoliberal regulatory institutions. This, however, neglects the multiple ways in which the wider politics of capital accumulation and distribution drive divergent forms of transformation in different urban places. In order to unpack the politics that shapes differential urban development, this book focuses on East Africa as the global urban frontier: the least urbanized but fastest urbanizing region in the world. Drawing on a decade of research spanning three case-study countries (Ethiopia, Rwanda, and Uganda), Politics and the Urban Frontier provides the first sustained, book-length comparative analysis of urban development trajectories in Eastern Africa and the political dynamics underpinning them. Through a focus on infrastructure investment, urban propertyscapes, street-level trading economies, and urban political protest, it offers a multi-scalar, historically grounded, and interdisciplinary analysis of the urban transformations unfolding in the world’s most dynamic crucible of urban change.

    Social Democratic Capitalism (2024)
    Oxford University Press
    Details
    Publication Date: 2024-03-29
    Description: What configuration of institutions and policies is most conducive to human flourishing? The historical and comparative evidence suggests that the answer is social democratic capitalism — a democratic political system, a capitalist economy, good elementary and secondary schooling, a big welfare state, pro-employment public services, and moderate regulation of product and labor markets. Lane Kenworthy shows that this system improves living standards for the least well-off, enhances economic security, and boosts equality of opportunity. And it does so without sacrificing other things we want in a good society, from liberty to economic growth to health and happiness. Its chief practitioners have been the Nordic nations. The Nordics have gone farther than other rich democratic countries in coupling a big welfare state with public services that promote high employment and modest product- and labor-market regulations. Many believe this system isn’t transferable beyond Scandinavia, but Kenworthy shows that social democratic capitalism and its successes can be replicated in other affluent nations, including the United States. Today, the U.S. lags behind other countries in economic security, opportunity, and shared prosperity. If the U.S. expanded existing social programs and added some additional ones, many Americans would have better lives. Kenworthy argues that, despite formidable political obstacles, the U.S. is likely to move toward social democratic capitalism in coming decades. As a country gets richer, he explains, it becomes more willing to spend more in order to safeguard against risk and enhance fairness. He lays out a detailed policy agenda that could alleviate many of America’s problems.

    Languages and Communities in the Late-Roman and Post-Imperial Western Provinces (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-02
    Description: Languages are central to the creation and expression of identities and cultures, as well as to life itself, yet the linguistic variegation of the later-Roman and post-imperial period in the Roman West is remarkably understudied. A deeper understanding of this important issue is crucial to any reconstruction of the broader story of linguistic continuity and change in Europe and the Mediterranean, as well as to the history of the communities who wrote, read, and spoke Latin and other languages. In spite of intensive study of culture and ethnic identity in late antiquity, language has often been neglected, a neglect encouraged by the disciplinary boundaries between linguists and historians, Romanists, and medievalists. There is no single volume that sets out the main developments, key features, and debates of the later-Roman and post-imperial linguistic environment. The linguistic landscapes of the late-Roman and post-imperial West are difficult to uncover and describe, while attempts to speak across disciplinary divides are challenging. The contributors have tackled this subject by offering detailed coverage of the Iberian Peninsula, North Africa, Gaul, the Germanies, Britain, and Ireland. This volume, the third in the LatinNow series, helps readers to understand better the embeddedness, or not, of Latin, at different social levels and across provinces, to consider (socio)linguistic variegation, bilingualism and multilingualism, and attitudes towards languages, and to confront the complex role of language in the communities, identities, and cultures of the later and post-imperial Roman West.

    Description: Students of particle physics often find it difficult to locate resources to learn calculational techniques. Intermediate steps are not usually given in the research literature. To a certain extent, this is also the case even in some of the textbooks. In this book of worked problems we have made an effort to provide enough details so that a student starting in the field will understand the solution in each case. Our hope is that with this step-by-step guidance, students (after first attempting the solution themselves) can develop their skill, and confidence in their ability, to work out particle theory problems.

    Description: Babies in Groups examines the consequences for science, for childcare policy, and for adult psychotherapy, of findings that young babies capably enjoy participating in groups. The authors’ research on preverbal infants’ capacities for group-communication in all-baby trios and quartets opens up new ways of imagining human development as fundamentally group-based. Babies in Groups highlights the changes a group-based vision of infancy brings to early child education and care by documenting the transformative consequences of introducing group-based practices into a high-quality childcare service in rural Australia. The book also examines the ways in which the belief that one-to-one infant-adult ‘attachments’ grounds human development unnecessarily narrows understanding of human potential, and slants scientific research. This examination culminates by showing how ignoring group contexts in many clinical traditions can distort descriptions of what happens in therapy, producing such unintended consequences as ‘mother-blaming’ for the future problems an infant may experience as she or he grows up.

    The Politics of Revenue Bargaining in Africa (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-03
    Description: This book examines the politics of revenue bargaining in Africa in a time when attention to domestic revenue mobilisation has expanded immensely. Measures to increase taxes and other revenues can -but do not always- lead to a process of bargaining, where revenue providers negotiate for some kind of a return. This book offers in-depth analyses of micro-instances of revenue bargaining across five African countries: Mozambique, Senegal, Tanzania, Togo, and Uganda. All case studies draw on a common theoretical framework combining the fiscal contract theory with the political settlement approach, which enables a systematic exploration into what triggers revenue bargaining; how these processes unfold; and finally, if and when they reach an agreement (whether a fiscal contract or not). From the empirically rich case narratives emerges a story of how power and initial bargaining position influence not only whether bargaining emerges in the first place, but also the processes and their outcomes. Less resourceful taxpayers are in a more difficult position to raise their voice, but in some cases even these groups manage to ally with other civil society groups to protest against tax reforms they perceive as unfair. Indirect taxes such as VAT often trigger protests, and so do sudden changes in tax practices. Revenue providers rarely call for improved services in return for paying tax, which would be expected to nurture the foundation for a fiscal social contract. Instead, revenue providers are more likely to negotiate for tax reductions, implying that governments’ effort to increase revenue is impeded. We do find many instances of state-society reciprocity when ruling elites try to be responsive to revenue providers’ demands. Hence, this book gives insight into the nature and dynamics not only of revenue bargaining but of policy-making in general as well as the implications hereof for state-society reciprocity in Africa.

    Description: Every day, two or three women die because of pregnancy or childbirth. Nearly 80% of these deaths are preventable. These outcomes disproportionately impact racialized populations, including Black and Indigenous women, who are two to three times more likely to die. The Practical Playbook III: Working Together to Improve Maternal Health is a guide for maternal health stakeholders (like researchers, community activists, providers, and advocates) offering practical tools and strategies to address inequities in maternal health services and outcomes. With contributions from more than 150 authors, each chapter offers a different strategy that stakeholders can apply to improve maternal health in their community. The 50 chapters are divided into six main sections: Section I, Introduction; Section II, Collaborations; Section III, Equity; Section IV, Data; Section V, Innovations; and Section VI, Systems and Scalability. The chapters focus on ways to save mothers by centering equity, collaborating with people with lived experience, building better data systems, piloting and expanding innovations, and leveraging resources to scale and sustain what works. Throughout the book, readers encounter stories from women and birthing people that bring the problems and solutions into better focus. The editors are committed to continuing to share information about initiatives that are moving the needle through our online platforms.

    Comparing the Worth of the While in Fiji and Finland (2024)
    Oxford University Press
    Details
    Publication Date: 2024-03-19
    Description: Comparing the Worth of the While in Fiji and Finland presents comparative case studies of clock time from Fiji and Finland in order to ask what other values is time capable of expressing besides monetary worth – what “else” can time be besides money? Time is a highly particular vehicle for different considerations of what is good or important, but it is also one which is deployed at different settings with surprisingly little consideration for the specificity of this particular a value form. This book looks into the different ways in which time is deployed in value projects in Fiji and Finland, not just to point out the various possible ways of allocating value to time, but to show that European clock-time, just like its Oceanic counterparts, requires a great deal of conceptual work to make it serve as vehicle of valuation. The cases analysed in the book range from considerations of rank and conspicuous leisure in Fiji to Finnish timebanking, taxation, and university auditing.

    The Impact of the Inter-American Human Rights System (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-07
    Description: The Inter-American Human Rights System (IAHRS) fosters structural transformations throughout the Americas. This collection of analyses builds upon the studies on Ius Constitutionale Commune en América Latina and Latin American transformative constitutionalism to map out both the ground-level human rights impact of the IAHRS and the institutional characteristics that have enabled such fundamental changes in social reality. The volume starts with essays framing the concept and context of IAHRS impact. Then it navigates thematic analyses on specific rights and types of violations that are front and center to the protection of human rights in Latin America. The concluding essays explore whether and how it is possible to optimize the actions of the Inter-American System, indicating possible paths to increase positive human rights impact. The editors contend that the IAHRS victim-centric approach, community of practice, and openness to institutional reinvention have enabled it to create a virtuous cycle that catalyzes human rights in the Americas, furthering democracy and the Rule of Law throughout the continent.

    The Nature of Physical Computation (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-14
    Description: Computing systems are everywhere today. Even the brain is thought to be a sort of computing system. But what does it mean to say that a given organ or system computes? What is it about laptops, smartphones, and nervous systems that they are deemed to compute, and why does it seldom occur to us to describe stomachs, hurricanes, rocks, or chairs that way? The book provides an extended argument for the semantic view of computation, which states that semantic properties are involved in the nature of computing systems. Laptops, smartphones, and nervous systems compute because they are accompanied by representations. Stomachs, hurricanes, and rocks, for instance, which do not have semantic properties, do not compute. The first part of the book argues that the linkage between the mathematical theory of computability and the notion of physical computation is weak. Theoretical notions such as algorithms, effective procedure, program, and automaton play only a minor role in identifying physical computation. The second part of the book reviews three influential accounts of physical computation and argues that while none of these accounts is satisfactory, each of them highlights certain key features of physical computation. The final part of the book develops and argues for a semantic account of physical computation and offers a characterization of computational explanations.

    Social Factors in the Latinization of the Roman West (2024)
    Oxford University Press
    Details
    Publication Date: 2024-05-11
    Description: Latinization is a strangely overlooked topic. Historians have noted it has been ‘taken for granted’ and viewed as an unremarkable by-product of ‘Romanization’, despite its central importance for understanding the Roman provincial world, its life and languages. This volume aims to fill the gap in our scholarship, along with its sister volumes, Latinization, Local Languages and Literacies in the Roman West and Languages and Communities in the Late-Roman and Post-Imperial Western Provinces, all outputs of the European Research Council-funded LatinNow project. Experts have been selected to create a multidisciplinary volume with a thematic approach to the vast subject, tackling administration, army, economy, law, mobility, religion (local and imperial religions and Christianity), social status, and urbanism. They situate the phenomena of Latinization, literacy, bi-, and multilingualism within local and broader social developments and draw together materials and arguments that have not before been coordinated in a single volume. The result is a comprehensive guide to the theme, which also offers original and more experimental work. The sociolinguistic, historical, and archaeological contributions reinforce, expand, and sometimes challenge our vision of Latinization and lay the foundations for future explorations.

    Responsibility and Healthcare (2024)
    Oxford University Press
    Details
    Publication Date: 2024-05-13
    Description: Questions of responsibility arise at all levels of health care. Most prominent has been the issue of patient responsibility. Some health conditions that risk death or serious harm are partly the result of lifestyle behaviours such as smoking, lack of exercise, or extreme sports. Are patients with such conditions responsible for them? If so, might healthcare providers, be they state-run systems or private entities, be justified in treating such patients differently? And if they are, which forms of differential treatment are justified? Responsibility isn’t just relevant for patients. Even when individuals affect their health through voluntary behaviour, other influences are also at work before, during, and after the patient’s interaction with the health care system. What are the responsibilities of individual clinicians and other medical professionals, when thinking about individual and public health? What about institutions such as governments or national health care services, or society as a whole? This collection brings together work by world-renowned experts in population ethics, distributive justice, philosophy of action, cognitive science, and medical ethics in order to push the debate forward by elucidating our understanding of these questions, their possible answers, and how they are related.

    Access to Power (2024)
    Oxford University Press
    Details
    Publication Date: 2024-03-29
    Description: Pakistan would desperately like to produce enough electricity, but it usually doesn’t. This is the rare issue on which government and private sector can unite, and it is the cause of suffering for rich and poor alike across the entirety of the country. Despite prioritization by successive governments, targeted reforms shaped by international development actors, and featuring prominently in Chinese Belt and Road Investments, the Pakistani power sector still stifles economic and social life across the country. This book explores state capacity in Pakistan by following the material infrastructure of electricity across the provinces and down into cities and homes. It argues that the national challenges of budgetary constraints and power shortages directly result from conscious strategic decisions that are integral to Pakistan’s infrastructural state. Electricity shortages are one of the many poor governance outcomes characteristic of low- and middle-income countries. Standard development thinking points to an absence of institutions in comparison with an idealized and distant other country, with governance reform programs formulated accordingly. However, an orientation toward what Pakistan is not takes us away from how it actually functions and to whose benefit. Electricity governance in Pakistan reinforces relations of power between provinces and the federal center, contributes to the marginalization of subordinate groups in the city, and orients citizens toward a patronage-based relationship with the state through encounters with street-level bureaucrats. Looking through the lens of the electrical power sector reveals how Pakistan works, and for whom.

    Would Democratic Socialism Be Better? (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-03
    Description: The case for a modern democratic humane socialism typically has two parts. The first is that capitalism is bad, at or least not very good. In reaching this conclusion, most have either analyzed a theoretical ideal-type of capitalism or used a single country, often the United States, as a stand-in for capitalism. To fully and fairly assess democratic socialism’s desirability, we need to compare it to the best version of capitalism that humans have devised: social democratic capitalism, or what is often called the Nordic model. Each chapter in this book examines one of the things that we should want in a good society, that contemporary democratic socialists typically say they want, and that socialism might, conceivably, improve our ability to achieve: an end to poverty in rich countries, an end to poverty everywhere, more jobs, decent jobs, faster economic growth, inclusive growth, more public goods and services, affordable healthcare for all, helpful finance, truly democratic politics, economic democracy, less economic inequality, gender and racial equality, more community, and a livable planet. The book offers a close look at the evidence about how capitalist economies have performed on these outcomes, with particular attention to the performance of social democratic capitalism. The second part of the case for democratic socialism is the notion that it would be an improvement. For each of these outcomes, the book considers what, if anything, we can conclude about whether democratic socialism would do better than social democratic capitalism.

    Mental Imagery (2024)
    Oxford University Press
    Details
    Publication Date: 2024-04-08
    Description: This book is about mental imagery and the important work it does in our mental life. It plays a crucial role in the vast majority of our perceptual episodes. It also helps us understand many of the most puzzling features of perception (like the way it is influenced in a top-down manner and the way different sense modalities interact). But mental imagery also plays a very important role in emotions, action execution, and even in our desires. In sum, there are very few mental phenomena that mental imagery doesn’t show up in—in some way or other. The hope is that if we understand what mental imagery is, how it works and how it is related to other mental phenomena, we can make real progress on a number of important questions about the mind. This book aims at an interdisciplinary audience. As it aims to combine philosophy, psychology, and neuroscience to understand mental imagery, I have not presupposed any prior knowledge in any of these disciplines. As a result, readers with no background in any of these disciplines can also follow the arguments.

    Age model of sediment core GeoTü SL167 (2024)
    PANGAEA
    Details
    Publication Date: 2024-02-02
    Description: The age model of sediment core GeoTü SL167 is based on 14C AMS measurements of planktonic foraminifera and is calibrated with the BACON v. 2.5.6 software for R (Blaauw & Christen, 2011) and a marine reservoir age of ΔR = 93 ± 61 years. The ΔR is based on the weighted mean of two regional marine reservoir corrections (Muscat) by Southon et al. (2002) using the marine calibration database (Reimer and Reimer, 2001, http://calib.org/marine/). Gravity core GeoTü SL167, was retrieved at station no. 960 during R.V. METEOR cruise M74/1b in 2007 (Bohrmann et al., 2010) from the northwestern Arabian Sea off Oman, at 22°37.2'N, 59°41.5'E, 774 m water depth, core recovery 7.39 m. The sediment core was retrieved for the reconstruction of circulation and productivity changes in the eastern Mediterranean Sea during the late Quaternary with particular focus on changes in the Indian monsoon system.

    Publication Date: 2024-02-02
    Description: The onset of the first sustained Antarctic glaciation at the Eocene-Oligocene Transition (~34 Ma; EOT) was marked by several changes in calcareous nannofossils coinciding with long-term cooling and modifications in the sea-surface water structure. Here, we combined a high-resolution calcareous nannofossil assemblage data (%) with bulk geochemical data from IODP Site U1509 (New Caledonia Trough, Tasman Sea) in order to give an overview of the paleoclimatic and palaeoceanographic evolution of the study area.

    Airborne gravity data across Astrid Ridge, East Antarctica (2024)
    PANGAEA
    Details
    Publication Date: 2024-03-01
    Description: This data set contains airborne gravity data across central Dronning Maud Land, East Antarctica, acquired during the austral summer of 2009/2010 and within the project 'West-East Gondwana Amalgamation and its Separation' (WEGAS). The data span the offshore Astrid Ridge, and parts of the Nivl and Lazarev ice shelves. The survey was conducted using a ZLS Ultrasys Lacoste & Romberg Air/Sea gravimeter S56 installed into - and operated with - the research aircraft Polar 5. Base readings were performed with a handheld gravity meter at the base station Novolazarevskaja and in Cape Town. A ground speed of 130 knots and a time-domain filter of 220 s leads to a spatial resolution of around 7 km. The average crossover error after bias adjustment is 4.2 mGal. When citing this data set, please also cite the associated manuscript: Eisermann, H., Eagles, G. & Jokat, W. Coastal bathymetry in central Dronning Maud Land controls ice shelf stability. Sci Rep 14, 1367 (2024). https://doi.org/10.1038/s41598-024-51882-2.

    Bathymetric model beneath Nivl and Lazarev ice shelves, and across Astrid Ridge embedded within IBCSOV2 (2024)
    PANGAEA
    Details
    Publication Date: 2024-03-01
    Description: Attached data comprise a bathymetric model of central Dronning Maud Land, including the seabed beneath the Nivl Ice Shelf and the Lazarev Ice Shelf, as well as the offshore Astrid Ridge and adjacent parts of the Riiser-Larsen Sea. Here, this model is embedded within the larger Antarctic-wide bathymetric compilation IBCSOV2 (Dorschel et al., 2022). This is an addition to the stand-alone bathymetric model here: https://doi.org/10.1594/PANGAEA.961492. The embedded model gives seabed depths relative to WGS84 at a resolution of 2.5 km. It is generated by complementing existing topographic data sets - such as seismic data, ice penetrating radar data, and shipborne hydroacoustic data - with the inversion of airborne gravity data towards bathymetry. The airborne gravity data used for the inversion consist of data acquired during aerogeophysical campaigns VISA from the early 2000s and WEGAS from the austral summer of 2009/2010. When citing this model, please also cite the associated manuscript: Eisermann, H., Eagles, G. & Jokat, W. Coastal bathymetry in central Dronning Maud Land controls ice shelf stability.

    Description: Solar radiation over and under sea ice was measured by radiation station 2019R8, an autonomous platform, installed on drifting First-Year-Ice (FYI) in the Arctic Ocean during MOSAiC (Leg 1) 2019/20. The resulting time series describes radiation measurements as a function of place and time between 05 October 2019 and 31 July 2020 in sample intervals of 3 hours. The radiation measurements have been performed with spectral radiometers. All data are given in full spectral resolution interpolated to 1.0 nm, and integrated over the entire wavelength range (broadband, total: 320 to 950 nm). Two sensors, solar irradiance and upward reflected solar irradiance, were mounted on a on a platform about 1 m above the sea ice surface. The third sensor was mounted 0.5 m underneath the sea ice measuring the downward transmitted irradiance. Along with the radiation measurements, this autonomous platform consisted of a 5 m long thermistor chain with sensor spacing of 0.02 m and several other sensor packages, which measured water temperature, pressure and conductivity at hourly intervals. Ecology sensors measured backscatter strength, chlorophyll a and fluorescence of dissolved organic matter at hourly intervals. Oxygen sensors measured relative oxygen air saturation, and water temperature at hourly intervals. In addition, relative snow height was measured at hourly intervals. All times are given in UTC.

    Publication Date: 2024-03-05
    Description: Solar radiation over and under sea ice was measured by radiation station 2019R8, an autonomous platform, installed on drifting First-Year-Ice (FYI) in the Arctic Ocean during MOSAiC (Leg 1) 2019/20. The resulting time series describes radiation measurements as a function of place and time between 05 October 2019 and 31 July 2020 in sample intervals of 3 hours. The radiation measurements have been performed with spectral radiometers. All data are given in full spectral resolution interpolated to 1.0 nm, and integrated over the entire wavelength range (broadband, total: 320 to 950 nm). Two sensors, solar irradiance and upward reflected solar irradiance, were mounted on a on a platform about 1 m above the sea ice surface. The third sensor was mounted 0.5 m underneath the sea ice measuring the downward transmitted irradiance. Along with the radiation measurements, this autonomous platform consisted of a 5 m long thermistor chain with sensor spacing of 0.02 m and several other sensor packages, which measured water temperature, pressure and conductivity at hourly intervals. Ecology sensors measured backscatter strength, chlorophyll a and fluorescence of dissolved organic matter at hourly intervals. Oxygen sensors measured relative oxygen air saturation, and water temperature at hourly intervals. In addition, relative snow height was measured at hourly intervals. All times are given in UTC.

    Details
    Publication Date: 2024-03-05
    Description: Solar radiation over and under sea ice was measured by radiation station 2019R8, an autonomous platform, installed on drifting First-Year-Ice (FYI) in the Arctic Ocean during MOSAiC (Leg 1) 2019/20. The resulting time series describes radiation measurements as a function of place and time between 05 October 2019 and 31 July 2020 in sample intervals of 3 hours. The radiation measurements have been performed with spectral radiometers. All data are given in full spectral resolution interpolated to 1.0 nm, and integrated over the entire wavelength range (broadband, total: 320 to 950 nm). Two sensors, solar irradiance and upward reflected solar irradiance, were mounted on a on a platform about 1 m above the sea ice surface. The third sensor was mounted 0.5 m underneath the sea ice measuring the downward transmitted irradiance. Along with the radiation measurements, this autonomous platform consisted of a 5 m long thermistor chain with sensor spacing of 0.02 m and several other sensor packages, which measured water temperature, pressure and conductivity at hourly intervals. Ecology sensors measured backscatter strength, chlorophyll a and fluorescence of dissolved organic matter at hourly intervals. Oxygen sensors measured relative oxygen air saturation, and water temperature at hourly intervals. In addition, relative snow height was measured at hourly intervals. All times are given in UTC.

    Description: We continuously measured aerosol size distributions in the range between 18 nm and 820 nm in 64 bit per decade resolution by means of a Scanning Mobility Particle Sizer (SMPS, TSI, i.e. a Series 3080 Electrostatic Classifier equipped with a Differential Mobility Analyzer DMA 3081). The measurements were conducted at the Air Chemistry Observatory (SPUSO) at Neumayer III Station (Antarctica) between 4 August 2023 and 31 December 2023. The data are based on an original 10-minute temporal resolution, submitted as 60-minute averages. Aerosol size distribution measurements are part of the air chemistry long-term observations at Neumayer III.

    Description: We operate a multi angle absorption photometer MAAP (Model 5012, Thermo Electron Corp.). which is in operation since March 2006 ongoing. This instrument measures atmospheric light absorption by aerosol (mainly caused by black carbon, BC). To this end, ambient aerosol was sampled on a glass filter tape. The measured absorption coefficients abs(637) refer to a wavelength of 637 nm. Raw data were originally sampled in one-minute resolution. Finally, hourly averaged MAAP data are presented here. We also provide BC concentrations (ng/m³) derived from the absorption coefficients using the specific BC attenuation cross section (QBC) of 6.6 m²/g.

    Description: We operate a 7-wavelength aethalometer (Model AE33, Magee Scientific) which is in operation since 23 January 2019 ongoing. The Aethalometer model AE33 collects aerosol particles continuously by drawing the aerosol-laden air stream through a spot on the filter tape. It analyzes the aerosol by measuring the transmission of light through one portion of the filter tape containing the sample, versus the transmission through an unloaded portion of the filter tape acting as a reference area. This analysis is done at seven optical wavelengths spanning the range from the near-infrared to the near-ultraviolet. The Aethalometer calculates the instantaneous concentration of optically-absorbing aerosols from the rate of change of the attenuation of light transmitted through the particle-laden filter.

    Publication Date: 2024-03-05
    Description: Multiproxy analysis (including magnetic susceptibility, diffuse spectral reflectance, elemental geochemistry and grain size) of five sediment piston cores (COR1404-001PC, COR1404-003PC, COR1404-006PC, COR1404-008PC and COR1404-011PC) in order to characterize the evolution of sedimentary environments and depositional history of the Gulf of San Jorge (Patagonia, Argentina) since the Last Glacial Maximum. The data were collected on board the R/V Coriolis II during the MARGES (Marine Geology of the Gulf of San Jorge) expedition (January 29 to March 4, 2014) as part of the PROMESSe (PROgrama Multidisciplinario para el Estudio del ecosistema y la geología marina del golfo San Jorge y las costas de las provincias de Chubut y Santa Cruz) project. Color reflectance, pXRF and magnetic susceptibility were performed at 1-cm intervals on freshly split core sections using a GEOTEK Multi-Sensor Core Logger. Prior to grain size analysis, the five piston cores were evenly sampled every 8 cm with a refined sampling at 4-cm intervals for basal sections of cores COR1404-003PC, COR1404-006PC and COR1404-008PC. Grain size analysis of sediment samples was carried out on the detrital fraction using a Beckman Coulter LS 13 320 particle size analyser. The age-depth models were generated with radiocarbon ages calibrated using the software CALIB version 7.1, the Marine13 calibration curve and a marine regional reservoir correction (ΔR) of 0. The “best fit” linearly interpolated age-depth models were constructed with the Bayesian statistical approach of the BACON v2.2 package of the R software.

    Description: Solar radiation over and under sea ice was measured by radiation station 2019R8, an autonomous platform, installed on drifting First-Year-Ice (FYI) in the Arctic Ocean during MOSAiC (Leg 1) 2019/20. The resulting time series describes radiation measurements as a function of place and time between 05 October 2019 and 31 July 2020 in sample intervals of 3 hours. The radiation measurements have been performed with spectral radiometers. All data are given in full spectral resolution interpolated to 1.0 nm, and integrated over the entire wavelength range (broadband, total: 320 to 950 nm). Two sensors, solar irradiance and upward reflected solar irradiance, were mounted on a on a platform about 1 m above the sea ice surface. The third sensor was mounted 0.5 m underneath the sea ice measuring the downward transmitted irradiance. Along with the radiation measurements, this autonomous platform consisted of a 5 m long thermistor chain with sensor spacing of 0.02 m and several other sensor packages, which measured water temperature, pressure and conductivity at hourly intervals. Ecology sensors measured backscatter strength, chlorophyll a and fluorescence of dissolved organic matter at hourly intervals. Oxygen sensors measured relative oxygen air saturation, and water temperature at hourly intervals. In addition, relative snow height was measured at hourly intervals. All times are given in UTC.

    Inorganic and organic carbon survey in surface soils of a Wadden Sea mainland salt marsh 17 years after land-use change (2024)
    PANGAEA
    Details
    Publication Date: 2024-03-05
    Description: Vegetated coastal ecosystems have been increasingly recognized for their capacity to sequester organic carbon in their soils and sediments under the term blue carbon. The vegetation of these habitats shows specific adaptations to severe abiotic soil conditions, particularly, waterlogging and salinity, and supports therefore ecosystem functioning and services. Wadden Sea salt marshes in Schleswig-Holstein (Germany) have been utilized for high density sheep grazing over centuries. At the beginning of the 1990s, in many parts of salt marshes livestock densities were reduced and the maintenance of the anthropogenic drainage system was ceased. In 2012, 17 years after the change of land utilization, the contents, densities, and accumulation rates of surface soil carbon were investigated at 50 sampling positions with different elevations along eight transects in Wadden Sea mainland salt marshes at Hamburger Hallig, Schleswig-Holstein, Germany, under different livestock grazing regimes (ungrazed, moderately grazed, intensively grazed). Surface soil was collected in 150 permanent plots (2 m * 2 m) at 50 sampling positions, covering a salt marsh area of 1050 ha. The carbon contents, pH, and bulk density were determined from dried soil. The elevations of the 150 permanent plots were measured and annual vertical accretion rates were calculated from 17 years sedimentation monitoring. This study was supported by the BASSIA project (Biodiversity, management, and ecosystem functions of salt marshes in the Wadden Sea National Park of Schleswig-Holstein), funded by the Bauer-Hollmann Foundation and Universität Hamburg.
