    Cold Air Outbreaks in Fram Strait: Climatology, Trends, and Observations During an Extreme Season in 2020 (2022)

    Description: Fram Strait in the northern North Atlantic is a key region for marine cold air outbreaks (MCAOs), southward discharges of polar air under northerly air flow, which have a strong impact on air-sea heat fluxes, boundary layer processes and severe weather. This study investigates climatologies and decadal trends of Fram Strait MCAOs of different intensity classes based on the ERA5 reanalysis product for 1979–2020. Among striking interannual variability, it is shown that the main MCAO season is December through March, when MCAOs occur around 2/3 of the time. We report on significant decadal MCAO decreases in December and January, and a significant increase in March. While the mid-winter decrease is mainly related to the different paces of warming between the surface and the lower atmosphere, the increase in March can be related to changes in synoptic circulation patterns. As an explanation for the latter, a possible feedback between retreating Barents Sea sea ice, enhanced cyclonic activity and Fram Strait MCAOs is postulated. Exemplifying the trend toward stronger MCAOs during March, the study details the recordbreaking MCAO season in early 2020, and an observational case study of an extreme MCAO event in March 2020 is conducted. Thereby, radiosonde observations are combined with kinematic air back-trajectories to provide rare observational evidence for the diabatic cooling and drying during the MCAO preconditioning phase.

    Reply to ‘Challenging the hypothesis of an arctic ocean lake during recent glacial episodes’ by Hillaire‐Marcel, et al (2022)

    Description: Hillaire‐Marcelet al. bring forward several physical and geochemical arguments against our finding of an Arctic glaciolacustrine system in the past. In brief, we find that a physical approach to further test our hypothesis should additionally consider the actual bathymetry of the Greenland–Scotland Ridge (GSR), the density maximum of freshwater at 3–4°C, the sensible heat flux from rivers, and the actual volumes that are being mixed and advected. Their geochemical considerations acknowledge our original argument, but they also add a number of assumptions that are neither required to explain the observations, nor do they correspond to the lithology of the sediments. Rather than being additive in nature, their arguments of high particle flux, low particle flux, export of 230Th and accumulation of 230Th, are mutually exclusive. We first address the arguments above, before commenting on some misunderstandings of our original claim in their contribution, especially regarding our dating approach.

    Multiple drivers and controls of pockmark formation across the Canterbury Margin, New Zealand (2022)
    Wiley
    In:  EPIC3Basin Research, Wiley, ISSN: 0950-091X
    Details
    Publication Date: 2022-05-03
    Description: Shallow seabed depressions attributed to focused fluid seepage, known as pock- marks, have been documented in all continental margins. In this study, we dem- onstrate how pockmark formation can be the result of a combination of multiple factors— fluid type, overpressures, seafloor sediment type, stratigraphy and bot- tom currents. We integrate multibeam echosounder and seismic reflection data, sediment cores and pore water samples, with numerical models of groundwa- ter and gas hydrates, from the Canterbury Margin (off New Zealand). More than 6800 surface pockmarks, reaching densities of 100 per km2, and an undefined number of buried pockmarks, are identified in the middle to outer shelf and lower continental slope. Fluid conduits across the shelf and slope include shal- low to deep chimneys/pipes. Methane with a biogenic and/or thermogenic origin is the main fluid forming flow and escape features, although saline and fresh- ened groundwaters may also be seeping across the slope. The main drivers of fluid flow and seepage are overpressure across the slope generated by sediment loading and thin sediment overburden above the overpressured interval in the outer shelf. Other processes (e.g. methane generation and flow, a reduction in hydrostatic pressure due to sea- level lowering) may also account for fluid flow and seepage features, particularly across the shelf. Pockmark occurrence coin- cides with muddy sediments at the seafloor, whereas their planform is elongated by bottom currents.

    Assessing the rate of crustal extension by 2D sequential restoration analysis: A case study from the active portion of the Malta Escarpment (2022)
    Wiley
    Details
    Publication Date: 2022-03-16
    Description: Tectono-stratigraphic interpretation and sequential restoration modelling was performed over two high-resolution seismic profiles crossing the Western Ionian Basin of southern Italy. This analysis was undertaken in order to provide greater insights and a more reliable assessment of the deformation rate affecting the area. Offshore seismic profiling illuminates the sub-seafloor setting where a belt of active normal faults slice across the foot of the Malta Escarpment, a regional-scale structural boundary inherited from the Permo-Triassic palaeotectonic setting. A sequential restoration workflow was established to back-deform the entire investigated sector with the primary aim of analysing the deformation history of the three major normal faults affecting the area. Restoration of the tectono-stratigraphic model reveals how deformation rates evolved through time. In the early stage, the studied area experienced a significant deformation with the horizontal component prevailing over the vertical element. In this context, the three major faults contribute to only one third of the total deformation. The overall throw and extension then notably reduced through time towards the present day and, since the middle Pliocene, ongoing crustal deformation is accommodated almost entirely by the three major normal faults. Unloading and decompaction indicate that when compared to the unrestored seismic sections, a revision and a reduction of roughly one third of the vertical displacement of the faults offset is required. This analysis ultimately allows us to better understand the seismic potential of the region.

    Always ready? Primary production of Arctic phytoplankton at the end of the polar night (2022)
    Wiley
    In:  EPIC3Limnology and Oceanography Letters, Wiley, 7(2), pp. 167-174, ISSN: 2378-2242
    Details
    Publication Date: 2022-03-25
    Description: The end of the polar night with the concurrent onset of photosynthetic biomass production ultimately leads to the spring bloom, which represents the most important event of primary production for the Arctic marine ecosystem. This dataset shows, for the first time, significant in situ biomass accumulation during the dark–light transition in the high Arctic, as well as the earliest recorded positive net primary production rates together with constant chlorophyll a-normalized potential for primary production through winter and spring. The results indicate a high physiological capacity to perform photosynthesis upon re-illumination, which is in the same range as that observed during the spring bloom. Put in context with other data, the results of this study indicate that also active cells originating from the low winter standing stock in the water column, rather than solely resting stages from the sediment, can seed early spring bloom assemblages.

    Description: Free access at https://onlinelibrary.wiley.com/doi/10.1111/1755-6724.14824
    Description: Earthquake is a sudden release of energy due to fault motions. The severity of the damages can be minimized by development of a culture of prevention which includes the Seismic Hazard Assessment, microzonation studies and appropriate building codes. Earthquake risk assessment methods require seismo tectonic information usually organized in earthquake catalogues utilized in Probabilistic Seismic Hazard Assessment (PSHA) based on initial work by Cornell (1968), where probability distributions for magnitudes and source site distances reported in earthquake catalogues were utilized for the first time. In following years the method furtherly improved reporting an upper bound on the earthquake magnitude in each region avoiding the inclusion of unrealistically big earthquakes. A different approach has been followed in Countries characterized by significant incompletenesses in available earthquake catalogues. In these places the Deterministic Seismic Hazard Assessment (DSHA) methods have been often utilized. In particular the DSHA takes into account the maximum possible earthquake to evaluate the intensity of seismic ground motion distribution at a site by taking account the seismotectonic setup of the area. A deepening in the knowledge of seismotectonics and of morphostructural features of the studied area has been carried out in pattern recognition studies (Gelfand et al., 1976 and references therein). More updated applications named Neo-Deterministic Seismic Hazard Assessment (NDSHA) proposed by Wang et al. (2021) also consider morphostructural zoning which, in turn, considers nodes (fractured areas), lineaments and topographical features like the maximal elevation and the minimal elevation of the studied area. The steepness of topographic surfaces and sharp variations in morphostructural parameters indicate high tectonic activity. Some geological features are also presently utilized in PSHA methods in some Countries and considers basic parameters like the top and the bottom of seismogenic layers deduced by faults geometry within the frame of the Earthquake Rupture Forecasting (Bird and Liu, 2007).

    Chronology of the Mediterranean sea‐level highstand during the Last Interglacial: a critical review of the U/Th‐dated deposits (2022)
    Wiley
    Details
    Publication Date: 2022-02-21
    Description: Relative sea‐level (RSL) evolution during Marine Isotopic Stage (MIS) 5 in the Mediterranean basin is still not fully understood despite a plethora of morphological, stratigraphic and geochronological studies carried out on highstand deposits of this area. In this review we assembled a database of 323 U/Th‐dated samples (e.g. corals, molluscs, speleothems) which were used to chronologically constrain RSL evolution within MIS 5. The application of strict geochemical criteria to the U/Th samples indicates that only ~33% of data available for the Mediterranean Sea can be considered ‘reliable’. Most of these data (~65%) refer to the MIS 5e highstand, while only ~17% could be related to the MIS 5a. No attribution to MIS 5c can be unequivocally supported. Nevertheless, the resulting framework does not allow us to define a satisfactory RSL trend during the MIS 5e highstand and subsequent MIS 5 substages. Overall, the proposed selection of reliable/unreliable data would be useful for detecting areas where MIS 5 substage attributions are not supported by confident U/Th chronological data and thus the related reconstructions need to be revised. In this regard, the resulting framework calls for a reappraisal and re‐examination of the Mediterranean records with advanced geochronological methodologies.

    Forebulge migration in the foreland basin system of the central‐southern Apennine fold‐thrust belt (Italy): New high‐resolution Sr‐isotope dating constraints (2022)
    Wiley
    Details
    Publication Date: 2022-02-25
    Description: The Apennines are a retreating collisional belt where the foreland basin system, across large domains, is floored by a subaerial forebulge unconformity developed due to forebulge uplift and erosion. This unconformity is overlain by a diachronous sequence of three lithostratigraphic units made of (a) shallow-water carbonates, (b) hemipelagic marls and shales and (c) siliciclastic turbidites. Typically, the latter two have been interpreted regionally as the onset of syn-orogenic deposition in the foredeep depozone, whereas little attention has been given to the underlying unit. Accordingly, the rate of migration of the central-southern Apennine fold-thrust beltforeland basin system has been constrained, so far, exclusively considering the age of the hemipelagites and turbidites, which largely post-date the onset of foredeep depozone. In this work, we provide new high-resolution ages obtained by strontium isotope stratigraphy applied to calcitic bivalve shells sampled at the base of the first syn-orogenic deposits overlying the Eocene-Cretaceous pre-orogenic substratum. Integration of our results with published data indicates progressive rejuvenation of the strata sealing the forebulge unconformity towards the outer portions of the foldthrust belt. In particular, the age of the forebulge unconformity linearly scales with the pre-orogenic position of the analysed sites, pointing to an overall constant migration velocity of the forebulge wave in the last 25 Myr.

    A message from the ‘underground forge of the gods’: history and current eruptions at Mt Etna (2022)
    Wiley
    Details
    Publication Date: 2022-01-11
    Description: Mt Etna has made headlines over the last weeks and months with spectacular eruptions, some of them highly explosive. This type of paroxysmal eruptive behaviour is characteristic of Etna’s activity over the past few decades and so it is no surprise that Etna is among the most active volcanoes worldwide. Etna is well-known for its extraordinary geology and due to its repeated eruptive activity it provides a continuous supply of new scientific opportunities to understand the inner workings of large basaltic volcanic systems. In addition to its scientific value, Etna is also a world famous tourist attraction and has been listed as a UNESCO World Heritage site in 2013 for its geological and cultural value and not least for its fine agricultural products. Etna’s status as an iconic volcano is not a recent phenomenon; in fact, Etna has been a literary fixture for at least 3000 years, giving rise to many ancient myths and legends that mark it as a special place, deserving of human respect. From the ancient eruptions to the latest events in February–April 2021, people try to explain and understand the processes that occur within and beneath the volcano. In this article, we briefly summarize the recent eruptive activity of Etna as well as the ancient myths and legends that surround this volcano, from the underground forge of Hephaestus to the adventures of Odysseus, all the way to the benefits and dangers the volcano provides to those living on its flanks today.

    Mesopelagic-epipelagic fish nexus in viability and feasibility of commercial-scale mesopelagic fisheries (2022)

Mesopelagic-epipelagic fish nexus in viability and feasibility of commercial-scale mesopelagic fisheries. Natural Resource Modeling, 35(4), (2022): e12350, https://doi.org/10.1111/nrm.12350.
    Description: While considerable scientific uncertainties persist for mesopelagic ecosystems, the fishing industry has developed a great interest in commercial exploitation with improved technologies as part of their search for new sources of feed for fishmeal and fish oil for aquaculture, which will intensify with the planet's growing population. The multiple uncertainties surrounding the ecosystem structure and particularly the size of biomass, hinder a good understanding of the risks associated with large-scale exploitation, which is needed for a management framework for sustainable ocean uses. Despite concerns regarding irreversible losses triggered by commercial fishing, work exploring the vulnerability of mesopelagic fish to harvesting is largely missing. This study investigates the economic feasibility of mesopelagic fishing which is the primary driver for any possible future expansion. Using very limited information currently available, we conduct a high-level assessment focusing on key ecological and economic interactions and develop an initial understanding of the economic feasibility of commercial harvesting for mesopelagic fish in the coming years. We conduct simulations using a classical bioeconomic model that captures two species groups, mesopelagic and epipelagic fish, using a wide range of price and cost parameters. We analyze different scenarios for the economic profitability of the fishery in a regional fishery management context. The results of our study highlight the importance of better understanding key biological and ecological mechanisms and parameters which can in turn help inform policies aimed at protecting the mesopelagic.

    Larval transport pathways from three prominent sand lance habitats in the Gulf of Maine (2022)

Larval transport pathways from three prominent sand lance habitats in the Gulf of Maine. Fisheries Oceanography, 31(3), (2022): 333– 352, https://doi.org/10.1111/fog.12580.
    Description: Northern sand lance (Ammodytes dubius) are among the most critically important forage fish throughout the Northeast US shelf. Despite their ecological importance, little is known about the larval transport of this species. Here, we use otolith microstructure analysis to estimate hatch and settlement dates of sand lance and then use these measurements to parametrize particle tracking experiments to assess the source–sink dynamics of three prominent sand lance habitats in the Gulf of Maine: Stellwagen Bank, the Great South Channel, and Georges Bank. Our results indicate the pelagic larval duration of northern sand lance lasts about 2 months (range: 50–84 days) and exhibit a broad range of hatch and settlement dates. Forward and backward particle tracking experiments show substantial interannual variability, yet suggest transport generally follows the north to south circulation in the Gulf of Maine region. We find that Stellwagen Bank is a major source of larvae for the Great South Channel, while the Great South Channel primarily serves as a sink for larvae from Stellwagen Bank and Georges Bank. Retention is likely the primary source of larvae on Georges Bank. Retention within both Georges Bank and Stellwagen Bank varies interannually in response to changes in local wind events, while the Great South Channel only exhibited notable retention in a single year. Collectively, these results provide a framework to assess population connectivity among these sand lance habitats, which informs the species' recruitment dynamics and impacts its vulnerability to exploitation.

Many of us are not aware that our day-to-day actions can have a cumulative effect on the health of the ocean and seas – a necessary resource that must be protected for all life on planet earth to exist. In other words, people lack a sense of ‘Ocean Literacy’ i.e. an understanding of the ocean’s influence on us and our influence on the ocean.

    The United Nations World Water Development Report 2018: Nature-Based Solutions for Water. (2022)
    UNESCO | Paris, France
    Details
    Publication Date: 2022-09-14
    Description: Nature-based solutions (NBS) are inspired and supported by nature and use, or mimic, natural processes to contribute to the improved management of water. An NBS can involve conserving or rehabilitating natural ecosystems and/or the enhancement or creation of natural processes in modified or artificial ecosystems. They can be applied at micro- (e.g. a dry toilet) or macro- (e.g. landscape) scales. Attention to NBS has significantly increased in recent years. This is evidenced through the mainstreaming of NBS into a wide range of policy advances, including in water resources, food security and agriculture, biodiversity, environment, disaster risk reduction, urban settlements, and climate change. This welcome trend illustrates a growing convergence of interests around the recognition of the need for common objectives and the identification of mutually supporting actions – as illustrated best in the 2030 Agenda for Sustainable Development through its acknowledgment of the interdependency of its various Goals and targets. Upscaling NBS will be central to achieving the 2030 Agenda for Sustainable Development. Sustainable water security will not be achieved through business-as-usual approaches. NBS work with nature instead of against it, and thereby provide an essential means to move beyond business-as-usual to escalate social, economic and hydrological efficiency gains in water resources management. NBS show particular promise in achieving progress towards sustainable food production, improved human settlements, access to water supply and sanitation services, and water-related disaster risk reduction. They can also help to respond to the impacts of climate change on water resources.

Ecology Letters, 25(7), (2022): 1640-1654, https://doi.org/10.1111/ele.14026.
    Description: Temporal correlations among demographic parameters can strongly influence population dynamics. Our empirical knowledge, however, is very limited regarding the direction and the magnitude of these correlations and how they vary among demographic parameters and species’ life histories. Here, we use long-term demographic data from 15 bird and mammal species with contrasting pace of life to quantify correlation patterns among five key demographic parameters: juvenile and adult survival, reproductive probability, reproductive success and productivity. Correlations among demographic parameters were ubiquitous, more frequently positive than negative, but strongly differed across species. Correlations did not markedly change along the slow-fast continuum of life histories, suggesting that they were more strongly driven by ecological than evolutionary factors. As positive temporal demographic correlations decrease the mean of the long-run population growth rate, the common practice of ignoring temporal correlations in population models could lead to the underestimation of extinction risks in most species.

    The Ecology and Oceanography of Harmful Algal Blooms: Multidisciplinary Approaches to Research and Management. Anton Bruum Memorial Lecture, presented 27 June 2005, UNESCO, Paris (2022)

    Description: Virtually every coastal country in the world is affected by harmful algal blooms (HABs, commonly called “red tides”). This diverse array of phenomena includes blooms of toxic, microscopic algae that lead to illness and death in humans, fish, seabirds, marine mammals, and other oceanic life. There are also non-toxic HABs that cause damage to ecosystems, fisheries resources, and recreational facilities, often due to the sheer biomass of the accumulated algae. The term “HAB” also applies to non-toxic macroalgae (seaweeds), which can cause major ecological impacts such as the displacement of indigenous species, habitat alteration and oxygen depletion in bottom waters. The frequency, spatial extent, and economic impact of HABs have all expanded in recent decades, in parallel with, and sometimes a result of, the world’s increasing exploitation on the coastal zone for shelter, food, recreation, and commerce. HABs are complex oceanographic phenomena that require multidisciplinary study ranging from molecular and cell biology to large-scale field surveys, numerical modelling, and remote sensing from space. Multi-lateral international programmes and bilateral initiatives are bringing scientists together from different countries and disciplines in a concerted attack on this complex and multi-faceted issue. Our understanding of these phenomena is increasing dramatically, and with this understanding come technologies and management tools that can reduce HAB incidence and impact. More effective HAB management is sure to be one major outcome of the growing investment in the Global Ocean Observing System. HABs will always be with us, and in the next few decades at least, are likely to continue to expand in geographic extent and frequency. Nevertheless, scientifically based management should permit full exploitation of fisheries, recreational, and commercial resources, despite the recurrent and diverse threat that HABs pose. This series of lectures is dedicated to the memory of the noted Danish oceanographer and first chairman of the Commission, Dr Anton Frederick Bruun. The "Anton Bruun Memorial Lectures" were established in accordance with Resolution 19 of the Sixth Session of the IOC Assembly, in which the Commission proposed that important inter-session developments be summarized by speakers in the fields of solid earth studies, physical and chemical oceanography and meteorology, and marine biology.

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, (2021.): 1-16, https://doi.org/10.1002/jez.b.23100.
    Description: Development of sexual characters and generation of gametes are tightly coupled with growth. Platynereis dumerilii is a marine annelid that has been used to study germline development and gametogenesis. P. dumerilii has germ cell clusters found across the body in the juvenile worms, and the clusters eventually form the gametes. Like other segmented worms, P. dumerilii grows by adding new segments at its posterior end. The number of segments reflect the growth state of the worms and therefore is a useful and measurable growth state metric to study the growth-reproduction crosstalk. To understand how growth correlates with progression of gametogenesis, we investigated germline development across several developmental stages. We discovered a distinct transition period when worms increase the number of germline clusters at a particular segment number threshold. Additionally, we found that keeping worms short in segment number, by manipulating environmental conditions or via amputations, supported a segment number threshold requirement for germline development. Finally, we asked if these clusters in P. dumerilii play a role in regeneration (as similar free-roaming cells are observed in Hydra and planarian regeneration) and found that the clusters were not required for regeneration in P. dumerilii, suggesting a strictly germline nature. Overall, these molecular analyses suggest a previously unidentified developmental transition dependent on the growth state of juvenile P. dumerilii leading to substantially increased germline expansion.

Impoundment increases methane emissions in Phragmites‐invaded coastal wetlands. Global Change Biology, 28(15), (2022): 4539– 4557. https://doi.org/10.1111/gcb.16217.
    Description: Saline tidal wetlands are important sites of carbon sequestration and produce negligible methane (CH4) emissions due to regular inundation with sulfate-rich seawater. Yet, widespread management of coastal hydrology has restricted tidal exchange in vast areas of coastal wetlands. These ecosystems often undergo impoundment and freshening, which in turn cause vegetation shifts like invasion by Phragmites, that affect ecosystem carbon balance. Understanding controls and scaling of carbon exchange in these understudied ecosystems is critical for informing climate consequences of blue carbon restoration and/or management interventions. Here, we (1) examine how carbon fluxes vary across a salinity gradient (4–25 psu) in impounded and natural, tidally unrestricted Phragmites wetlands using static chambers and (2) probe drivers of carbon fluxes within an impounded coastal wetland using eddy covariance at the Herring River in Wellfleet, MA, United States. Freshening across the salinity gradient led to a 50-fold increase in CH4 emissions, but effects on carbon dioxide (CO2) were less pronounced with uptake generally enhanced in the fresher, impounded sites. The impounded wetland experienced little variation in water-table depth or salinity during the growing season and was a strong CO2 sink of −352 g CO2-C m−2 year−1 offset by CH4 emission of 11.4 g CH4-C m−2 year−1. Growing season CH4 flux was driven primarily by temperature. Methane flux exhibited a diurnal cycle with a night-time minimum that was not reflected in opaque chamber measurements. Therefore, we suggest accounting for the diurnal cycle of CH4 in Phragmites, for example by applying a scaling factor developed here of ~0.6 to mid-day chamber measurements. Taken together, these results suggest that although freshened, impounded wetlands can be strong carbon sinks, enhanced CH4 emission with freshening reduces net radiative balance. Restoration of tidal flow to impounded ecosystems could limit CH4 production and enhance their climate regulating benefits.

    Diel light cycles affect phytoplankton competition in the global ocean (2022)

J., Dutkiewicz, S., Follett, C. L., & Vallino, J. J. Diel light cycles affect phytoplankton competition in the global ocean. Global Ecology and Biogeography, 31(9), (2022): 1838-1849, https://doi.org/10.1111/geb.13562.
    Description: Aim Light, essential for photosynthesis, is present in two periodic cycles in nature: seasonal and diel. Although seasonality of light is typically resolved in ocean biogeochemical–ecosystem models because of its significance for seasonal succession and biogeography of phytoplankton, the diel light cycle is generally not resolved. The goal of this study is to demonstrate the impact of diel light cycles on phytoplankton competition and biogeography in the global ocean. Location Global ocean. Major taxa studied Phytoplankton. Methods We use a three-dimensional global ocean model and compare simulations of high temporal resolution with and without diel light cycles. The model simulates 15 phytoplankton types with different cell sizes, encompassing two broad ecological strategies: small cells with high nutrient affinity (gleaners) and larger cells with high maximal growth rate (opportunists). Both are grazed by zooplankton and limited by nitrogen, phosphorus and iron. Results Simulations show that diel cycles of light induce diel cycles in limiting nutrients in the global ocean. Diel nutrient cycles are associated with higher concentrations of limiting nutrients, by 100% at low latitudes (−40° to 40°), a process that increases the relative abundance of opportunists over gleaners. Size classes with the highest maximal growth rates from both gleaner and opportunist groups are favoured by diel light cycles. This mechanism weakens as latitude increases, because the effects of the seasonal cycle dominate over those of the diel cycle. Main conclusions Understanding the mechanisms that govern phytoplankton biogeography is crucial for predicting ocean ecosystem functioning and biogeochemical cycles. We show that the diel light cycle has a significant impact on phytoplankton competition and biogeography, indicating the need for understanding the role of diel processes in shaping macroecological patterns in the global ocean.

Ecology Letters, 25, (2022): 1189– 1201, https://doi.org/10.1111/ele.13991.
    Description: Spatial synchrony may be tail-dependent, that is, stronger when populations are abundant than scarce, or vice-versa. Here, ‘tail-dependent’ follows from distributions having a lower tail consisting of relatively low values and an upper tail of relatively high values. We present a general theory of how the distribution and correlation structure of an environmental driver translates into tail-dependent spatial synchrony through a non-linear response, and examine empirical evidence for theoretical predictions in giant kelp along the California coastline. In sheltered areas, kelp declines synchronously (lower-tail dependence) when waves are relatively intense, because waves below a certain height do little damage to kelp. Conversely, in exposed areas, kelp is synchronised primarily by periods of calmness that cause shared recovery (upper-tail dependence). We find evidence for geographies of tail dependence in synchrony, which helps structure regional population resilience: areas where population declines are asynchronous may be more resilient to disturbance because remnant populations facilitate reestablishment.

Synchronous-clock range-angle relative acoustic navigation: a unified approach to multi-AUV localization, command, control, and coordination. Journal of Field Robotics, 2(1), (2022): 774–806, https://doi.org/10.55417/fr.2022026.
    Description: This paper presents a scalable acoustic navigation approach for the unified command, control, and coordination of multiple autonomous underwater vehicles (AUVs). Existing multi-AUV operations typically achieve coordination manually by programming individual vehicles on the surface via radio communications, which becomes impractical with large vehicle numbers; or they require bi-directional intervehicle acoustic communications to achieve limited coordination when submerged, with limited scalability due to the physical properties of the acoustic channel. Our approach utilizes a single, periodically broadcasting beacon acting as a navigation reference for the group of AUVs, each of which carries a chip-scale atomic clock and fixed ultrashort baseline array of acoustic receivers. One-way travel-time from synchronized clocks and time-delays between signals received by each array element allow any number of vehicles within receive distance to determine range, angle, and thus determine their relative position to the beacon. The operator can command different vehicle behaviors by selecting between broadcast signals from a predetermined set, while coordination between AUVs is achieved without intervehicle communication by defining individual vehicle behaviors within the context of the group. Vehicle behaviors are designed within a beacon-centric moving frame of reference, allowing the operator to control the absolute position of the AUV group by repositioning the navigation beacon to survey the area of interest. Multiple deployments with a fleet of three miniature, low-cost SandShark AUVs performing closed-loop acoustic navigation in real-time provide experimental results validated against a secondary long-baseline positioning system, demonstrating the capabilities and robustness of our approach with real-world data.

Ecology Letters, 25(8), (2022): 1854-1868, https://doi.org/10.1111/ele.14066.
    Description: Spatial synchrony is a ubiquitous and important feature of population dynamics, but many aspects of this phenomenon are not well understood. In particular, it is largely unknown how multiple environmental drivers interact to determine synchrony via Moran effects, and how these impacts vary across spatial and temporal scales. Using new wavelet statistical techniques, we characterised synchrony in populations of giant kelp Macrocystis pyrifera, a widely distributed marine foundation species, and related synchrony to variation in oceanographic conditions across 33 years (1987–2019) and 〉900 km of coastline in California, USA. We discovered that disturbance (storm-driven waves) and resources (seawater nutrients)—underpinned by climatic variability—act individually and interactively to produce synchrony in giant kelp across geography and timescales. Our findings demonstrate that understanding and predicting synchrony, and thus the regional stability of populations, relies on resolving the synergistic and antagonistic Moran effects of multiple environmental drivers acting on different timescales.

Journal of Field Robotics, 2(1), (2022): 1351–1385, https://doi.org/10.55417/fr.2022045.
    Description: In this report, we present the system design, operational strategy, and results of coordinated multivehicle field demonstrations of autonomous marine robotic technologies in search-for-life missions within the Pacific shelf margin of Costa Rica and the Santorini-Kolumbo caldera complex, which serve as analogs to environments that may exist in oceans beyond Earth. This report focuses on the automation of remotely operated vehicle (ROV) manipulator operations for targeted biological sample-collection-and-return from the seafloor. In the context of future extraterrestrial exploration missions to ocean worlds, an ROV is an analog to a planetary lander, which must be capable of high-level autonomy. Our field trials involve two underwater vehicles, the SuBastian ROV and the Nereid Under Ice (NUI) hybrid ROV for mixed initiative (i.e., teleoperated or autonomous) missions, both equipped seven-degrees-of-freedom hydraulic manipulators. We describe an adaptable, hardware-independent computer vision architecture that enables high-level automated manipulation. The vision system provides a three-dimensional understanding of the workspace to inform manipulator motion planning in complex unstructured environments. We demonstrate the effectiveness of the vision system and control framework through field trials in increasingly challenging environments, including the automated collection and return of biological samples from within the active undersea volcano Kolumbo. Based on our experiences in the field, we discuss the performance of our system and identify promising directions for future research.

Global Change Biology, 28, (2022): 2236– 2258, https://doi.org/10.1111/gcb.16041.
    Description: Climate impacts are not always easily discerned in wild populations as detecting climate change signals in populations is challenged by stochastic noise associated with natural climate variability, variability in biotic and abiotic processes, and observation error in demographic rates. Detection of the impact of climate change on populations requires making a formal distinction between signals in the population associated with long-term climate trends from those generated by stochastic noise. The time of emergence (ToE) identifies when the signal of anthropogenic climate change can be quantitatively distinguished from natural climate variability. This concept has been applied extensively in the climate sciences, but has not been explored in the context of population dynamics. Here, we outline an approach to detecting climate-driven signals in populations based on an assessment of when climate change drives population dynamics beyond the envelope characteristic of stochastic variations in an unperturbed state. Specifically, we present a theoretical assessment of the time of emergence of climate-driven signals in population dynamics (ToEpop). We identify the dependence of (ToEpop)on the magnitude of both trends and variability in climate and also explore the effect of intrinsic demographic controls on (ToEpop). We demonstrate that different life histories (fast species vs. slow species), demographic processes (survival, reproduction), and the relationships between climate and demographic rates yield population dynamics that filter climate trends and variability differently. We illustrate empirically how to detect the point in time when anthropogenic signals in populations emerge from stochastic noise for a species threatened by climate change: the emperor penguin. Finally, we propose six testable hypotheses and a road map for future research.

    Description: Over the past two decades, scientific research on the connections between the health and resilience of marine ecosystems and human health, well-being, and community prosperity has expanded and evolved into a distinct “metadiscipline” known as Oceans and Human Health (OHH), recognized by the scientific community as well as policy makers. OHH goals are diverse and seek to improve public health outcomes, promote sustainable use of aquatic systems and resources, and strengthen community resilience. OHH research has historically included some level of community outreach and partner involvement; however, the increasing disruption of aquatic environments and urgency of public health impacts calls for a more systematic approach to effectively identify and engage with community partners to achieve project goals and outcomes. Herein, we present a strategic framework developed collaboratively by community engagement personnel from the four recently established U.S. Centers for Oceans and Human Health (COHH). This framework supports researchers in defining levels of community engagement and in aligning partners, purpose, activities, and approaches intentionally in their community engagement efforts. Specifically, we describe: (a) a framework for a range of outreach and engagement approaches; (b) the need for identifying partners, purpose, activities, and approaches; and (c) the importance of making intentional alignment among them. Misalignment across these dimensions may lead to wasting time or resources, eroding public trust, or failing to achieve intended outcomes. We illustrate the framework with examples from current COHH case studies and conclude with future directions for strategic community engagement in OHH and other environmental health contexts.

    Description: There have been spectacular advances in the field of artificial intelligence (AI) in recent years, leading to inventions that we had never thought possible. Computers and robots now have the capacity to learn how to improve their own work, and even make decisions – this is done through an algorithm, of course, and without individual consciousness. All the same, we must not fail to ask some questions. Can a machine think? Towards a global code of ethics for artificial intelligence research © Evgenija Demnievska (evgenijademnievska.com) What is an AI capable of at this stage of its evolution? To what degree is it autonomous? Where does that leave human decision-making? More than ushering in a Fourth Industrial Revolution, AI is provoking a cultural revolution. It is undeniably destined to transform our future, but we don’t know exactly how, yet. This is why it inspires both fascination and fear. In this issue, the Courier presents its investigation to the reader, elaborating on several aspects of this cutting-edge technology at the frontiers of computer science, engineering and philosophy. It sets the record straight on a number of points along the way. Because, let’s be clear – as things stand, the AI cannot think. And we are very far from being able to download all the components of a human being into a computer! A robot obeys a set of routines that allows it to interact with us humans, but outside the very precise framework within which it is supposed to interact, it cannot forge a genuine social relationship. Even so, some of AI’s applications are already questionable – data collection that intrudes on privacy, facial recognition algorithms that are supposed to identify hostile behaviour or are imbued with racial prejudice, military drones and autonomous lethal weapons, etc. The ethical problems that AI raises – and will undoubtedly continue to raise tomorrow, with greater gravity – are numerous. While research is moving full speed ahead on the technical side of AI, not much headway has been made on the ethical front. Though many researchers have expressed concern about this, and some countries are starting to give it serious thought, there is no legal framework to guide future research on ethics on a global scale. “It is our responsibility to lead a universal and enlightened debate in order to enter this new era with our eyes wide open, without sacrificing our values, and to make it possible to establish a common global foundation of ethical principles,” says Director- General Audrey Azoulay, of UNESCO’s role, in this issue of the Courier (see pp. 37-39). An international regulatory instrument is essential for the responsible development of AI, a task that UNESCO is in the process of undertaking. The Courier lends this initiative its support, by exploring different avenues of thought on the subject.

    Transboundary Water Cooperation and the Sustainable Development. (2022)
    UNESCO | Paris, France
    Details
    Publication Date: 2022-09-30
    Description: The last several years have seen a discernible shift in global priorities towards advancing the concept of sustainable development. In particular, the establishment of the post-2015 development agenda and the 17 Sustainable Development Goals (SDGs) by the UN General Assembly points towards an integrated plan towards tackling global challenges. The goals seek to protect and improve five key areas of the world including people, planet, prosperity, peace and partnership. The intent of this paper is to emphasize the vital role that transboundary water cooperation plays in global development, and to map out the relationship that this cooperation has with the other goals. Existing and emerging rules and institutions have been developed in international law to minimise, and where possible halt, negative consequences stemming from poor management of transboundary waters. SDG 6 provides for an important spotlight on improving water and sanitation, however for the context of global development it is crucial for water management to be interpreted and actionably combined with the other relevant SDGs, rather than curtailed as an individual entity. From direct linkages to indirect references, transboundary water cooperation is intrinsically connected to several other principles of sustainable development reflected in the goals and targets, including environment, energy, and food amongst others, and therefore must be viewed as an integral piece of global water management. Furthermore, Target 6.5 requires a set of two indicators in order to fully capture the importance of both integrated water resources management (IWRM) and transboundary water cooperation in the implementation of the SDGs. It is paramount that an indicator is retained solely for the transboundary water cooperation element embedded in Target 6.5. This paper advocates for an indicator that should be broad enough to reward also cooperative frameworks aimed at developing a sound system of exchange of information, and not only fully fledged IWRM systems. This is particularly important in the context of transboundary aquifers governance, where many of the cooperative frameworks being discussed are at a very initial stage. The indicator can be reviewed throughout the implementation of the SDGs, especially in relation to the quantity and quality of the information that needs to be exchanged in order to meet the indicator. UNESCO-IHP and UNECE can play an important role, together with other members of UN Water, in monitoring this much needed indicator.

    Evaluation of the strategic positioning of IOC-UNESCO. (2022)
    UNESCO | Paris, France
    Details
    Publication Date: 2022-09-30
    Description: In 2017, the UN General Assembly declared the UN Decade of Ocean Science for Sustainable Development (2021-2030). It has entrusted IOC-UNESCO with the design and delivery of the Decade to ensure that ocean science is indeed underpinning sustainable ocean management and the 2030 Sustainable Development Agenda more broadly. Fulfilling its mandate as trustee of the Ocean Decade, as well as delivering on a growing list of additional roles, in an oceanographic space that is both expanding and increasingly crowded, establishes an important opportunity but also an overarching challenge for IOC-UNESCO. In the context of the upcoming UN Decade of the Ocean, the IOC-UNESCO agreed with the Internal Oversight Service (IOS) on the merit of conducting an evaluation of its strategic positioning within the UN system and the broader landscape of ocean-related actors and programmes, taking into account relevant enabling policy frameworks to which the work of the Commission responds.

The United Nations have proclaimed the Decade to support efforts to gather ocean stakeholders worldwide behind a common framework that will ensure that ocean science can fully support countries in creating improved conditions for the sustainable development of the Ocean. 2. The Scientific and Technical Advisory Body (STAB) elaborated a Strategic Framework (see also full text in annex) on engaging in the UN Decade and presented it to the 8th Meeting of States Parties in 2021. The Meeting, in Resolution 4/8 MSP, welcomed the STAB’s Strategic Framework and reiterated the need to ensure full authorization of the concerned States and respect of confidentiality for unprotected sites in all mapping processes foreseen in it. The Meeting also called on Member States to support actions in the framework of the UN Decade of Ocean Science focusing on underwater and coastal cultural heritage financially. 3. In this regard, in February 2022, a letter was sent by the Secretariat to the States Parties to raise funding for the implementation of the Strategic Framework. Pending the necessary additional contributions, the STAB is invited to determine the priorities among the actions proposed in the Strategic Framework to launch its implementation.

    UNESCO and the Ocean. [Item 29 of the provisional agenda for the 214th Session of the Executive Board.] (2022)
    UNESCO | Paris, France
    Details
    Publication Date: 2022-09-30
    Description: This item has been included in the provisional agenda of the 214th session of the Executive Board at the request of Colombia, Egypt, Kenya, Monaco, Morocco, Oman, Palau, Portugal, Serbia and Togo. An explanatory note, together with a proposed decision is attached. 1. The United Nations Educational, Scientific and Cultural Organization (UNESCO) undertakes a significant number of ocean-related activities. Founded in 1960, UNESCO’s Intergovernmental Oceanographic Commission (IOC) brings together 150 Member States. It coordinates major global ocean programmes such as ocean observing, data management, tsunami warning, develops ecosystem-based approaches to ocean management, and acts as a custodian agency for reporting on SDG targets 14.3 and 14.a. UNESCO is also the guardian of 232 marine biosphere reserves and 50 marine World Heritage sites of outstanding universal value. 2. It is within this context that UNESCO, through IOC, is coordinating the United Nations Decade of Ocean Science for Sustainable Development (“the Ocean Decade”), from 2021 to 2030. The Ocean Decade provides a common framework to ensure that ocean science can ably support countries in achieving the 2030 Agenda for Sustainable Development. This year, the Ocean Decade is high on agenda of major international summits, such as the “One Ocean Summit” (Brest, February 2022) and the UN Ocean Conference (Lisbon, June 2022), setting the stage for collective mobilization on ocean and climate issues at the 27th session of the Conference of the Parties (COP 27, Sharm El-Sheikh, November 2022) to the United Nations Framework Convention on Climate Change (UNFCCC). 3. At the One Ocean Summit, UNESCO announced its readiness to work with partners towards complete mapping of the seabed by 2030, compared to 20% currently, and to expand the work on ocean literacy, contributing to establishing more harmonious relations between humans and the ocean. These two announced ambitions complement other major UNESCO activities related to the ocean. It is relevant to note in this connection that knowledge of high-resolution ocean depth is essential to identifying the location of ocean faults, understanding of ocean currents, tides, and transport of sediments, anticipating seismic and tsunami risks, identifying natural sites and living marine resources that need to be safeguarded for sustainable exploitation. 4. The UNESCO ocean activities are conducted in line with resolutions and decisions adopted by UNESCO and IOC Member States. The second strategic objective of the UNESCO Medium-Term Strategy (2022-2029) is to “work towards sustainable societies by preserving the environment through the promotion of science, technology and natural heritage”. Its third outcome is to “enhance knowledge for climate action, respect for biodiversity, water and ocean management, and disaster risk reduction”. The IOC Medium-Term Strategy (2022-2029) focuses on ocean health, ocean-climate nexus, hazard warnings, ocean economy and knowledge of emerging ocean science issues. This work strongly contributes to the achievement of the 2030 Agenda for Sustainable Development, including Goal 14 “Conserve and sustainably use the Oceans, seas and marine resources for sustainable development”. 5. Overall, the negative impact of climate change, land-based pollution, and other stressors on the ocean and marine life is alarming. While there is considerable progress on the international arena in terms of awareness, global efforts deployed so far to overcome these negative effects are still not up to the hoped-for level. 6. The combination of the forthcoming African Conference on Priority Setting and Partnership Development for the UN Decade of Ocean Science for Sustainable Development (Alexandria, May 2022) and the UNFCCC COP 27 (Sharm el-Sheikh, November 2022) represents a unique opportunity to develop an active research agenda on ocean and climate in line with the UNESCO global priority of Africa. 7. It is suggested therefore that Executive Board adopt a decision that UNESCO continues its active involvement in major ocean related events of 2022, and supports IOC in developing necessary partnerships, further strengthening momentum of the Ocean Decade, successfully seeking extrabudgetary resources and increasing UNESCO’s overall contribution to the protection of the seas and ocean from the effects of climate change as well as the preservation of the sustainability and diversity of marine life.

    Water education for climate resilience in Asia and the Pacific: a regional curriculum. (2022)
    UNESCO | Paris, France
    Details
    Publication Date: 2022-10-04
    Description: A fundamental element towards attaining water security, water education has been at the heart of UNESCO’s Intergovernmental Hydrological Programme since its establishment in 1975. However, in much of Asia and the Pacific, water security remains elusive. Ensuring a water secure future for the region will require the unlocking of broader appreciation, acceptance and internalization of basic water science principles and concepts among experts and communities alike. For this, broader and more effective water education is required. For this potential to be fulfilled, reinforced human, financial and technical resources are required to deliver education, training and capacity development across large segments of society. Not only does this require the mobilization of a much larger contingent of trainers, instructors and conveners—it requires the development of new teaching and learning approaches, methodologies and curricula. This curriculum represents an invitation to tertiary-level educators as well as water managers and decision-makers to redouble efforts towards water security in Asia and the Pacific – and invitation grounded in a process that lies at the heart of UNESCO’s mission: the sharing of knowledge, experience and technologies – in this case among scientific, educational and water management communities across the region. Published with the support of the Government of Japan.

    Proceedings of the 2nd International Conference on Water, Megacities & Global Change, 11-14 January 2022 - ONLINE. (2022)
    UNESCO | Paris, France
    Details
    Publication Date: 2022-10-03
    Description: Six years after the First International Conference on “Water, Megacities and Global Change”, held on the occasion of the 21st United Nations Conference on Climate Change (COP 21), which drew attention to the significant challenges megacities are facing, and proposed the creation of the Megacities Alliance on Water and Climate (MAWAC), UNESCO’s Division of Water Sciences and ARCEAU-IdF1 decided to join forces once again to co-organize the Second International Conference on Water, Megacities and Global Change (EauMega) at UNESCO Headquarters in Paris, France and online on a dedicated platform for the conference, on 11-14 January 2022. Organized in close collaboration with the Greater Paris Metropolis and the Greater Paris Sanitation Authority (SIAAP), and with the support of many other public and private partners, this conference builds on the results of the online Pre-Conference on Water, Megacities and Global Change, which took place in December 2020. The Pre-Conference event, which brought together more than 6,000 participants, helped the organizers identify the issues requiring further consideration during the Second International Conference on Water, Megacities and Global Change by selected scientists, water operators, decision-makers, representatives of basin authorities and civil society at large. Given their size, the challenges posed to Megacities by water management within the context of climate change are of particular importance. Indeed, they raise new and specific issues that require close collaboration between scientists who advance knowledge, operators and basin authorities (public and private) who innovate technically and socio-politically, and local decision-makers who can support new, just and more efficient models of water governance, while remaining in constant interaction with civil society. Following a Call for Papers launched in late 2019, this publication is a compilation of the best scientific articles selected and peer-reviewed by the 87 international experts responsible for designing the scientific programme of the conference. Reflecting the structure of the conference with its 12 thematic sessions, the Proceedings present all the peer-reviewed articles in the following thematic chapters: • Disaster Risk Reduction; • Sustainable Development Goals & Service continuity; • Knowledge of the technical and social conditions; • Governance modalities in megacities; • Holistic water management; • Land issues and challenges; • Planning tools. • Technical and technological solutions; • Innovative initiatives at governance, technical, institutional or social level; • New water culture; • Strengthening of sustainable solidarity; The publication not only provides a state of the art on the challenges that Megacities are facing in their management of water and of the new global changes they encounter, but also presents the latest innovative and multi-disciplinary solutions being used to overcome these challenges and ensure optimal and sustainable resource management. By compiling a collection of experiences and best practices at global level, integrating the following three aspects – megacities, water and global change including climate change – it is our hope that this publication will represent a source of inspiration for other Megacities and large urban centers to overcome similar challenges and strengthen their climate resilience. By promoting fruitful exchanges and synergies among megacities, research institutions, the private sector and civil society at large, as well as inspiring further joint research studies on climate change and water-security related issues, the conference represents without doubt a fundamental building block of the Megacities Alliance on Water and Climate (MAWAC). On behalf of the Conference organizers, we wish to thank the co-conveners and partners of this second major international Conference on Water, Megacities and Global Change, as well as all the authors for their valuable contribution and their recommendations.

    Publication Date: 2022-08-12
    Description: In every ocean, regional and national tsunami warning systems must maintain a high level of readiness so as to be able to efficiently and effectively act to provide for the public’s safety during fast-onset and rapidly-evolving natural disasters involving marine inundation of coastal areas. Because of the relative infrequency of tsunamis, but knowing that tsunamis can have widespread impact across oceans and seas, the UNESCO/IOC and its Member States have been advocating through their Intergovernmental Coordination Groups (ICGs) for the regular conduct of tsunami exercises. To maintain a high state of operational readiness, National Tsunami Warning Centres (NTWCs) and Civil Protection agencies (CPA) must regularly practice their emergency response procedures to ensure that vital communication links work seamlessly, and that agencies and response personnel know the roles that they will need to play during a real event.

    Tsunami glossary. Fourth edition. (2022)
    UNESCO | Paris, France
    Details
    Publication Date: 2022-08-12
    Description: International coordination of a tsunami warning system originated in the Pacific in 1968 under the auspices of the Intergovernmental Oceanographic Commission of UNESCO in cooperation with the International Tsunami Information Centre (ITIC) established on 12 November 1965 by the Intergovernmental Oceanographic Commission (IOC) and hosted by the National Weather Service of the National Oceanic and Atmospheric Administration (USA). As early as 1988, experts and Member States recognized the need to develop standardized tsunami terminology in the form of a glossary which had endorsement of the scientific community. The first edition of the Tsunami Glossary (IOC Technical series, 37, 1991) was published by IOC and ITIC and contained more than 2000 terms and definitions building on disciplines such as geophysics, oceanography, engineering and mathematics. Following the Indian Ocean tsunami of December 2004, the IOC was mandated by the United Nations to coordinate development of similar regional tsunami and other coastal hazards warning and mitigation systems in the Caribbean, the Northeastern Atlantic and the Mediterranean Sea, the Indian Ocean in addition to the Pacific Ocean. Expert groups from different regional perspectives developed a common understanding of language to be used for the development of the four regional systems. Under the coordination of ITIC, this international effort resulted in 2008 in a new edition of the Tsunami Glossary (IOC Technical Series No 85). Over the years the Glossary has been translated and is available in English (original), Arabic, Chinese, French, Indonesian, Spanish, Urdu, Korean, Tagalog, Thai and several other languages. Since 2015 changes to the content of the Tsunami Glossary are subject to the validation of the IOC Working Group on Tsunamis and Other Hazards related to Sea-Level Warning and Mitigation Systems (TOWS-WG) and subsequent endorsement by the Governing Bodies of the IOC. By this mechanism it is expected that the publication will be recognized and adopted by Member States as a validated standard in this field. The 2019 edition of Tsunami Glossary includes the definition of technical terms, and information on the expert and governance groups for tsunami warning and mitigation.

    Benthic Carbon Remineralization and Iron Cycling in Relation to Sea Ice Cover along the Eastern Continental Shelf of the Antarctic Peninsula (2022)
    Wiley
    In:  EPIC3Journal of Geophysical Research-Oceans, Wiley, ISSN: 0148-0227
    Details
    Publication Date: 2022-06-29
    Description: Rapid and profound climatic and environmental changes have been predicted for the Antarctic Peninsula with so far unknown impact on the biogeochemistry of the continental shelves. In this study, we investigate benthic carbon sedimentation, remineralization and iron cycling using sediment cores retrieved on a 400 mile transect with contrasting sea ice conditions along the eastern shelf of the Antarctic Peninsula. Sediments at comparable water depths of 330-450 m showed sedimentation and remineralization rates of organic carbon, ranging from 2.5-13 and 1.8-7.2 mmol C m-2 d-1, respectively. Both rates were positively correlated with the occurrence of marginal sea ice conditions (5-35% ice cover) along the transect, suggesting a favorable influence of the corresponding light regime and water column stratification on algae growth and sedimentation rates. From south to north, the burial efficiency of organic carbon decreased from 58% to 27%, while bottom water temperatures increased from -1.9 to -0.1 °C. Net iron reduction rates, as estimated from pore-water profiles of dissolved iron, were significantly correlated with carbon degradation rates and contributed 0.7-1.2% to the total organic carbon remineralization. Tightly coupled phosphate-iron recycling was indicated by significant covariation of dissolved iron and phosphate concentrations, which almost consistently exhibited P/Fe flux ratios of 0.26. Iron efflux into bottom waters of 0.6-4.5 µmol Fe m-2 d-1 was estimated from an empirical model. Despite the deep shelf waters, a clear bentho-pelagic coupling is indicated, shaped by the extent and duration of marginal sea ice conditions during summer, and likely to be affected by future climate change.

    Rotation at subduction margins: How complexity at fault‐scale (the 2019 Albanian Mw 6.4 earthquake) mirrors the regional deformation (2022)
    Wiley
    Details
    Publication Date: 2022-06-24
    Description: A variety of tectonic processes spread along the circum-Mediterranean orogenic belts driven by the convergence of major plates, episodes of slab retreat and lateral and vertical mantle flows. Here, we provide an updated view of crustal stress and strain-rate fields for the Albanides belt in the eastern Adria-Eurasia convergence boundary. We framed a new geodetic-based source model for the 2019 Mw6.4 Durrёs earthquake in light of the regional deformation, propending for a transpressional west-dipping seismogenic fault. Our results highlight a fault-scale complexity which mirrors the long-time scale deformation of the Albanides plate boundary, where the rotation induced by the fast Hellenic rollback is accommodated also by transpression on inherited structures.

    Energy facies : A global view of pyroclastic currents from vent to deposit (2022)
    Wiley
    Details
    Publication Date: 2022-05-24
    Description: Pyroclastic currents are described as gravity currents, and the classic conceptual model gives a first-order importance to the density of such currents. This directs quantitative models to assume specific flow structures (shallow water or equilib rium turbulent boundary layer), which may apply to restricted volcanic areas inde pendently of source dynamics or may correspond to source dynamics separate from topographic interaction. The recent introduction of two end-members of pyroclastic currents, inertial and forced, is further developed here, leading to a global conceptual model in which source dynamics and topographic interaction are both taken into account. The concept of energy facies is defined here as the ensemble of the first order indicators of pyroclastic currents (topological aspect ratio, competence ratio and emplacement temperature) that are proxies of the energy of such currents. Nine energy facies are introduced with general applicability and with the goal to globally characterize pyroclastic currents from vent to deposit.

    Differential effects of elevated 〈scp〉 〈i〉p〈/i〉 CO 〈sub〉2〈/sub〉 〈/scp〉 and warming on marine phytoplankton stoichiometry (2022)
    Wiley
    In:  EPIC3Limnology and Oceanography, Wiley, 67(3), pp. 598-607, ISSN: 0024-3590
    Details
    Publication Date: 2022-09-15
    Description: Phytoplankton stand at the base of the marine food-web, and play a major role in global carbon cycling. Rising CO2 levels and temperatures are expected to enhance growth and alter carbon:nutrient stoichiometry of marine phytoplankton, with possible consequences for the functioning of marine food-webs and the oceanic carbon pump. To date, however, the consistency of phytoplankton stoichiometric responses remains unclear. We therefore performed a meta-analysis on data from experimental studies on stoichiometric responses of marine phytoplankton to elevated pCO2 and 3–5° warming under nutrient replete and limited conditions. Our results demonstrate that elevated pCO2 increased overall phytoplankton C:N (by 4%) and C:P (by 9%) molar ratios under nutrient replete conditions, as well as phytoplankton growth rates (by 6%). Nutrient limitation amplified the CO2 effect on C:N and C:P ratios, with increases to 27% and 17%, respectively. In contrast to elevated pCO2, warming did not consistently alter phytoplankton elemental composition. This could be attributed to species- and study-specific increases and decreases in stoichiometry in response to warming. While our observed moderate CO2-driven changes in stoichiometry are not likely to drive marked changes in food web functioning, they are in the same order of magnitude as current and projected estimations of oceanic carbon export. Therefore, our results may indicate a stoichiometric compensation mechanism for reduced oceanic carbon export due to declining primary production in the near future.

    Publication Date: 2022-09-14
    Description: © The Author(s), 2022. This article is distributed under the terms of the Creative Commons Attribution License. The definitive version was published in Thomas, M., Jensen, F. H., Averly, B., Demartsev, V., Manser, M. B., Sainburg, T., Roch, M. A., & Strandburg-Peshkin, A. A practical guide for generating unsupervised, spectrogram-based latent space representations of animal vocalizations. The Journal of Animal Ecology, 91(8), (2022): 1567– 1581, https://doi.org/10.1111/1365-2656.13754.
    Description: 1. Background: The manual detection, analysis and classification of animal vocalizations in acoustic recordings is laborious and requires expert knowledge. Hence, there is a need for objective, generalizable methods that detect underlying patterns in these data, categorize sounds into distinct groups and quantify similarities between them. Among all computational methods that have been proposed to accomplish this, neighbourhood-based dimensionality reduction of spectrograms to produce a latent space representation of calls stands out for its conceptual simplicity and effectiveness. 2. Goal of the study/what was done: Using a dataset of manually annotated meerkat Suricata suricatta vocalizations, we demonstrate how this method can be used to obtain meaningful latent space representations that reflect the established taxonomy of call types. We analyse strengths and weaknesses of the proposed approach, give recommendations for its usage and show application examples, such as the classification of ambiguous calls and the detection of mislabelled calls. 3. What this means: All analyses are accompanied by example code to help researchers realize the potential of this method for the study of animal vocalizations.

    Safeguarding Underwater Cultural Heritage in the Pacific: Report on good practice in the protection and management of world war II- related Underwater Cultural Heritage (2022)
    UNESCO | Paris, France
    Details
    Publication Date: 2022-09-07
    Description: This publication outlines good management practices but also explores how the protection of WWII UCH can benefit local communities and contribute to sustainable development in the region. The Pacific region covers about one-third of the total surface area of the Earth and has a long history of human migration and settlement. Beneath the waters of the Pacific Ocean lie traces of human existence that span across the centuries. These sites include ancient sunken villages, traditional fish traps of indigenous communities, and shipwrecks of missionaries and explorers. There is also a large number of shipwrecks and aircraft dated from WWII when the Pacific Ocean became the theatre of some of the fiercest battles of that time. Some of these sites are the final resting place of many lives and remain a sombre reminder of tragedies that wars bring upon people. Today many of these sites have become popular diving sites for tourists. However, some of the WWII-related UCH are slowly degrading with increasing risk of oil pollution, particularly in the event of severe storms.
    Description: Tokai University and the Heritage Emergency Fund at UNESCO
    Description: UNESCO hopes that government officials, policymakers, academics and communities engaged in UCH and broader ocean management issues will use this work as a resource to develop guidelines for the effective and sustainable management of WWII-related UCH in the Pacific.

    Agenda 2030: challenges for us all. (2022)
    UNESCO | Paris, France
    Details
    Publication Date: 2022-09-21
    Description: The publication of this issue marking the relaunch of the UNESCO Courier is particularly fitting, given that it falls within the 2030 Agenda for Sustainable Development that the United Nations adopted in September 2015. This new agenda represents a turning point towards a more humanistic attitude in global development policies, relying on people’s capacities to respond to the challenges of peace and climate change through education, science and culture, which is an underlying element of each of the objectives of sustainable development. We are convinced that in a world full of limitations — in terms of our resources and our means — humanity can count on the renewable resources of its intelligence, creativity and ingenuity. This wealth, fostered by the moral requirement to respect the rights and dignity of each individual, represents an infinite source of progress. To unlock this potential, we must also help raise awareness of the creative wealth of humanity, and the Courier can contribute to this by circulating words of peace, trust and intelligence in response to the discourse of hatred, fear and rejection that currently spreads so easily on the internet and on the streets. The UNESCO Courier is also a powerful tool of this fundamental aspiration, and I call upon all UNESCO Member States and partners, and first and foremost all intellectuals, artists and experts, to make their voices heard by enriching the pages of this Courier, which has inspired so many generations of readers and will continue to do so for a long time.

    UNESCO | Paris, France
    Details
    Publication Date: 2022-09-21
    Description: UNESCO’s Global Action Programme (GAP) was launched at the World Conference on Education for Sustainable Development (ESD) in November 2014 in Aichi-Nagoya, Japan as a follow-up programme to the Decade of ESD (2005-2014). Five Partner Networks were established by UNESCO to drive implementation of the GAP on ESD and to serve as a global community of practice. A Partner Network exists for each of the GAP’s five Priority Action Areas, which are: 1) advancing policy; 2) transforming learning and training environments; 3) building capacities of educators and trainers; 4) empowering and mobilizing youth; 5) accelerating sustainable solutions at local level. This booklet contains profiles of the current 96 members (also called Key Partners) of the GAP Partner Networks. Each Key Partner is listed in alphabetical order within one of the five Partner Networks. Each profile presents the main objective of their work, their GAP launch commitment and specific activities that contribute to the GAP, as well as related website links and contact information for the organization’s focal point. Key Partners are chosen from all regions of the world for their extensive outreach capacity and their ability to innovate and have major impact on ESD. Key Partners are expected to create synergies and joint activities among themselves, as well as to reach out to a wider group of stakeholders beyond the Partner Networks. This booklet will facilitate and intensify synergies between the GAP activities of the Key Partners, and catalyze further action from other ESD stakeholders. It complements the GAP Information folder ( http://unesdoc. unesco.org/images/0024/002462/246270e.pdf) by offering additional details on each GAP Key Partner. The Key Partners’ profiles will also be made available on the UNESCO GAP Clearinghouse website: https://en.unesco.org/gap At the back of the booklet you will also find a list of UNESCO GAP Secretariat staff who can be contacted for assistance on relevant topics and activities.

    Transcriptome-proteome compendium of the Antarctic krill (Euphausia superba): Metabolic potential and repertoire of hydrolytic enzymes (2022)
    Wiley
    In:  EPIC3Proteomics, Wiley
    Details
    Publication Date: 2022-07-20
    Description: The Antarctic krill (Euphausia superba Dana) is a keystone species in the Southern Ocean that uses an arsenal of hydrolases for biomacromolecule decomposition to effectively digest its omnivorous diet. The present study builds on a hybrid-assembled transcriptome (13,671 ORFs) combined with comprehensive proteome profiling. The analysis of individual krill compartments allowed detection of significantly more different proteins compared to that of the entire animal (1,464 vs. 294 proteins). The nearby krill sampling stations in the Bransfield Strait (Antarctic Peninsula) yielded rather uniform proteome datasets. Proteins related to energy production and lipid degradation were particularly abundant in the abdomen, agreeing with the high energy demand of muscle tissue. A total of 378 different biomacromolecule hydrolysing enzymes were detected, including 250 proteases, 99 CAZymes, 14 nucleases and 15 lipases. The large repertoire in proteases is in accord with the protein-rich diet affiliated with E. superba’s omnivorous lifestyle and complex biology. The richness in chitin-degrading enzymes allows not only digestion of zooplankton diet, but also the utilization of the discharged exoskeleton after moulting.

    The United Nations world water development report 2019: leaving no one behind. (2022)
    UNESCO | Paris, France
    Details
    Publication Date: 2022-11-02
    Description: Access to water is a human right: it is vital for the dignity of each and every individual. The 2019 edition of the World Water Development Report focuses on the theme of “Leaving No One Behind”. It argues that fulfilling the human rights to safe drinking water and sanitation for all can also significantly contribute to the achievement of the broad set of goals of the 2030 Agenda for Sustainable Development: from food and energy security, to economic development and environmental sustainability. Based on the latest data, this report’s findings clearly illustrate the need to make substantial progress towards delivering on the 2030 Agenda promise of reaching the most vulnerable. The stakes are high: nearly a third of the global population do not use safely managed drinking water services and only two fifths have access to safely managed sanitation services. The intensification of environmental degradation, climate change, population growth and rapid urbanisation — among other factors — also pose considerable challenges to water security. Furthermore, in an increasingly globalised world, the impact of water-related decisions cross borders and affect everyone. At the current pace of progress, billions of people will remain unable to enjoy their right to access to water and sanitation and the multiple benefits that such access can provide. Yet, this report concludes these objectives are entirely achievable, so long as there is a collective will to do so, entailing new efforts to include those ‘left behind’ in decision-making processes. This latest Report, coordinated by UNESCO, is the result of a collaborative effort of the UN-Water Family and was made possible thanks to the long-standing support of the Government of Italy and the Umbria Region, to whom we are extremely grateful.

    Global Harmful Algal Bloom: status report 2021 : A Scientific Summary for Policy Makers. (2022)
    UNESCO | Paris, France
    Details
    Publication Date: 2022-11-02
    Description: Among the approximately 10,000 beneficial species of marine phytoplankton in the world’s oceans today, some 200 taxa can harm human society through the production of toxins that threaten seafood security and human health. These toxins are also responsible for wild or aquaculture fish-kills, may interfere with recreation-al use of coastal or inland waters, or cause economic losses. Non-toxic microalgae attaining high biomass can also cause Harmful Algal Blooms (HABs) by producing seawater discolorations, anoxia or mucilage that negatively affect the environment and human activities. The most frequently asked questions about harmful algal blooms are if they are increasing and expand-ing worldwide, and what are the mechanisms behind this perceived escalation. These questions have been addressed in several review papers concerning HAB trends at various scales, where evidences of expansion, intensification and increased impacts of harmful algal blooms have been gathered from a selection of examples that have gained high prominence in the scientific world and in society 1,2,3,4. Eutrophication, human-mediated introduction of alien harmful species, climatic variability, and aquaculture have all been mentioned as possible causes of HAB trends at various spatial and temporal scales 5,6. Over the last 40 years, the capacity and monitoring efforts to detect harmful species and harmful events have significantly increased, thus increasing the reporting of harmful events across the world’s seas. The resulting information is mostly scattered in the ever growing literature, with data from statutory monitoring programs often not published in peer review journals, while an extensive and detailed overview of the huge amount of information on harmful species, their spatial and temporal distribution and the trends of HABs they have caused has never been attempted so far. This lack of a synthesis of the relevant data has hampered a sound global assessment of the present status of phenomena related to harmful algae. Following the lead of the International Panel for Climate Change (IPCC) consensus reporting mechanism, and to complement the World Ocean Assessment, the need has been expressed for a Global HAB Status Report compiling an overview of Harmful Algal Bloom events and their societal impacts; providing a worldwide appraisal of the occurrence of toxin-producing microalgae; aimed towards the long term goal of assessing the status and probability of change in HAB frequencies, intensities, and range resulting from environmental changes at the local and global scale. This initiative was launched in April 2013 in Paris by the IOC Intergovernmental Panel on HABs (IOC/IPHAB), and has been pursued with the support of the Government of Flanders and hosted within the IOC International Oceanographic Date Exchange Programme (IODE) in partnership with ICES, PICES and IAEA. As a first step towards a global HAB status assessment, a Special Issue of the journal Harmful Algae (vol. 102, February 2021) has been published comprising 12 papers 7-18 each presenting an overview of toxic and non-toxic HABs in a specific area of the world’s seas. The regional overviews build on existing literature and exploit the information gathered in two relevant data-bases, both incorporated into the Ocean Biodiversity Information System (OBIS).

    Brilliantia kiribatiensis, a new genus and species of Cladophorales (Chlorophyta) from the remote coral reefs of the Southern Line Islands, Pacific Ocean (2022)

    Description: The marine green alga Brilliantia kiribatiensis gen. et sp. nov. is described from samples collected from the coral reefs of the Southern Line Islands, Republic of Kiribati, Pacific Ocean. Phylogenetic analysis of sequences of the large- and small-subunit rDNA and the rDNA internal transcribed spacer region revealed that Brilliantia is a member of the Boodleaceae (Cladophorales), containing the genera Apjohnia, Boodlea, Cladophoropsis, Chamaedoris, Phyllodictyon, and Struvea. Within this clade it formed a distinct lineage, sister to Struvea elegans, but more distantly related to the bona fide Struvea species (including the type S. plumosa). Brilliantia differs from the other genera by having a very simple architecture forming upright, unbranched, single-celled filaments attached to the substratum by a rhizoidal mat. Cell division occurs by segregative cell division only at the onset of reproduction. Based on current sample collection, B. kiribatiensis seems to be largely restricted to the Southern Line Islands, although it was also observed on neighboring islands, including Orona Atoll in the Phoenix Islands of Kiribati, and the Rangiroa and Takapoto Atolls in the Tuamotus of French Polynesia. This discovery highlights the likeliness that there is still much biodiversity yet to be discovered from these remote and pristine reefs of the central Pacific.

    Neogene and Quaternary reef terraces of Mangaia, Rarotonga and Aitutaki (southern Cook Islands, South Pacific) revisited: gauges of sea-level change and island uplift? (2022)
    Wiley
    Details
    Publication Date: 2022-12-19
    Description: New sedimentological data of facies and diagenesis as well as chronological data including strontium (87Sr/86Sr)-isotope ratios and uranium (U)-series dating, radiocarbon (14C) accelerator mass spectrometry (AMS) dating and biostratigraphy from elevated reef terraces (makatea) in the southern Cook Islands of Mangaia, Rarotonga and Aitutaki contribute to controversial discussions regarding age and sea-level relationships of these occurrences during the Neogene and Quaternary. The oldest limestones of the uplifted makatea island of Mangaia include reef-related facies which are mid-Miocene in age, based on new Sr-isotope and biostratigraphical data. In between these older deposits and the lowest coastal reef terrace of marine isotope stage (MIS) 5e, various older Pleistocene reef-related facies were identified. Based on Sr-isotope ratios, these were deposited during earlier Pleistocene highstands (as old as 2.28 Ma). Rare reef terraces on Rarotonga belong to the Plio-Pleistocene and the late Miocene, according to 87Sr/86Sr ratios. The late Miocene age is enigmatic as it exceeds the age of subaerially exposed volcanic rocks of Rarotonga island. The fossil reef could have formed on an older submarine volcanic high that was later displaced by younger volcanism to its present position, or the Sr-age could be too old due to diagenetic resetting. The Plio-Pleistocene Rarotonga reef terraces are overlain irregularly by Holocene reef deposits that are interpreted as storm rubble. Reef terraces on Aitutaki represent evidence of a higher-than-present (up to 1 m) sea-level during the late Holocene, based on 14C AMS age data. They are very similar to elevated late Holocene reefs of adjacent French Polynesia with regard to composition, elevation and age.
