title: Daily sea level anomalies from satellite altimetry with Random Forest Regression

description: The sea level observations from satellite altimetry are characterised by a sparse spatial and temporal coverage. For this reason, along-track data are routinely interpolated into daily grids. The latter are strongly smoothed in time and space and are generated using an optimal interpolation routine requiring several pre-processing steps and covariance characterisation. In this study, we assess the potential of Random Forest Regression to estimate daily sea level anomalies. Along-track sea level data from 2004 are used to build a training dataset whose predictors are the neighbouring observations. The validation is based on the comparison against daily averages from tide gauges. The generated dataset is on average 10\% more correlated to the tide gauge records than the commonly used product from Copernicus. While the latter is more optimised for the detection of spatial mesoscales, we show how the methodology of this study has the potential to improve the characterisation of sea level variability.

title: Land-sea linkages on the Algerian Margin over the last 14 kyrs BP: climate variability at orbital to centennial timescales

description: Past and present environmental conditions over the Holocene along the Algerian coast involve complex atmosphere-hydrosphere-biosphere interactions and anthropogenic activities on adjacent watersheds. Atlantic Ocean surface waters entering the western Mediterranean Sea at the Gibraltar Strait leads to the Algerian Current, which flows along the North African coast in a succession of strong and large-scale eddies. Deep-water upwelling plumes are other recurrent hydrological features of the Algerian margin impacting on regional environmental features. However, vegetation and paleohydrological changes that occurred over the Holocene have not been described so far. To fill this gap, a suite of paleoclimate proxies was analysed in the marine core MD04-2801 (2,067 m water depth) at a secular-scale resolution over the last 14 kyrs BP. Terrestrial (pollen grains) and marine (dinoflagellate cysts or dinocysts) palynological assemblages, as well as sedimentological (grain-size analysis and XRD-based quantitative analysis of clay minerals) and biomarkers (alkenones and n-alkanes), were determined to explore the links between past sea surface hydrological conditions and regional environmental changes on nearby watersheds. Our data underline the unique character of our results in terms of dinocyst assemblages including the over-representation of heterotrophic dinocyst taxa (Brigantedinium spp.) signing for strong planktonic productivity in the study area. The Modern Analogue Technique applied to the new pollen and dinocyst assemblages reconstructed in this study also provides unique climatic and hydrological quantifications, respectively. We then discuss the links between dryness on land and surface hydrological conditions, and notably : (i) recurrent upwelling cells during the relatively dry climate conditions of the Younger Dryas (12.7 to 11.7 ka BP), the Early Holocene (11.7 to 8.2 ka BP) and from 6 ka BP onwards, (ii) enhanced fluvial discharges between 8.2 and 6 ka BP during the African Humid Period concomitant with the colonization of coastlands by the Mediterranean forest.

title: A monthly climatological analysis of the temperature and salinity of the Mid-Atlantic Bight and Gulf of Maine continental shelf, and adjacent deep ocean, by 4-dimensional weighted least squares

description: A high spatial resolution monthly mean climatological analysis of ocean hydrographic conditions (temperature and salinity) spanning the Mid-Atlantic Bight and Gulf of Maine region of the U.S. northeast continental shelf, and adjacent deep ocean, has been developed. The underlying observations for this Mid-Atlantic Ocean Climatological and Hydrographic Atlas (MOCHA) were obtained from the World Ocean Database (Boyer et al. 2009), the NOAA Northeast Fisheries Science Center database, and directly from local principal investigators whose data were not present, at the time of download, in the larger archives. The assembled data comprised 30,306,552 temperature and 10,258,727 salinity observations made between January 1864 and November 2009. Details of the analysis methodology are presented in Fleming (2016). In brief, the quality screened hydrographic profiles were mapped onto 57 standard depths and then interpolated onto a regular horizontal roughly 5-km resolution spatial grid using a loess filter weighted least squares approach based on the methodology of Ridgway et al. (2002). The adaptive local weights were dependent on horizontal distance, vertical distance, day-of-year, and ocean depth at the observation location so as to favor weighting in the along-isobath direction. The MOCHA analysis was a key data set used by Levin et al. (2018) to constrain a data-assimilative analysis of the mean and seasonal cycle of circulation in the Mid-Atlantic Bight. The resulting kinematically and dynamically constrained Mean Dynamic Topography substantially improved upon existing products available to the coastal satellite altimetry community. The MOCHA dataset is presented in a single NetCDF file adhering to CF-1.6 conventions. Boyer, T.P., J. I. Antonov , O. K. Baranova, H. E. Garcia, D. R. Johnson, R. A. Locarnini, A. V. Mishonov, T. D.

title: Annual growth of Laternula elliptica shells from Dumont d'Urville Station (Adélie Land, East Antarctica)

description: Laternula elliptica is one of the largest bivalve mollusk in Antarctic waters. Its shell presents annual growth increments that can be crossdated for the construction of master chronologies. Inter-annual variations of the resulting growth indices are driven by environmental forcings, among which sea ice and sympagic algae dynamics are the main ones. These two datasets present shell growth data collected in cross-sections of chondrophores (hinge area) of 27 Laternula elliptica specimens harvested by SCUBA diving near Dumont d'Urville Station (Adélie Land, East Antarctica) in January 2016. A calendar year was assigned to each annual growth increment by visual crossdating backward from the sampling year. Growth increment widths, expressed in micrometers, were measured from the last deposited growth increment (margin) toward earlier growth years (raw increment width µm file). Each individual time-series of growth increment width was first power-transformed, then detrended with a negative exponential function to compute two time-series of annual growth indices, with or without prewhitening by fitting an autoregressive model (growth indices file).

title: Perceptions of managers about Brazilian PAs

description: Brazil is one of the mega biodiverse countries on the planet. As a strategy to safeguard its biodiversity, the country has heavily relied on protected areas (PAs). However, gaps in research and management of PAs, in Brazil and in other countries, still exist, so studies that include Rapid Assessment and Prioritization of Protected Areas Management (RAPPAM) are essential to evaluate the role and performance of PAs. The aim of this data colection was, among others, to assess the effectiveness of Brazilian PAs based on perceptions of managers and researchers, using a mix-method approach that includes, but is not limited to, RAPPAM. We applied two online surveys (OSs), in 2016 and 2017, with managers and other staff of Brazilian PAs, and obtained 306 fully- or partially-responded surveys. The research permits required at the time of the beginning of this research project (April 2015) were obtained from ICMBio. OS1 was authorized under the registration number 55227-1 with the Biodiversity Authorization and Information System (SISBio) and OS2 was authorized under the registration number 55227-2. This survey compiled with informed consent, privacy and confidentiality procedures, in addition to the right to withdraw from the online surveys prior to publication.

title: Wave tank testing of a multi-purpose platform with aquaculture, wind turbine and wave energy converters

description: This dataset was collected during the experimental model tests carried out in the frame of the Blue Growth Farm project (EU–H2020 project 774426). The project aims at the development and demonstration of an automated, multifunctional platform for open sea farm installations of the Blue Growth Industry. This modular and environmentally friendly platform gathers aquaculture systems, a wind turbine and a set of wave energy converters. Experiments are performed to prepare the outdoor tests of a 1/15 prototype, and to validate an aero-hydro-servo-elastic coupled numerical model. Tests were carried out in the 50mx30mx5m hydrodynamic and ocean engineering tank of Centrale Nantes. A 1/40th scaled model of an aquaculture platform including a wind turbine and wave energy converters was designed and built. This platform is moored with four aerial lines and several combinations of wind and wave conditions are tested based on recommended procedures. The test list includes regular and irregular waves with the 3 different configurations : 1) with fish nets and with active wave energy converters, 2) with active wave energy converters and without fishnets 3) without fishnets and without wave energy converters.

title: Surface quasi-geostrophic model and application to vortex merger : results and data

description: The merger of two surface quasi-geostrophic vortices is examined in detail. As the two vortices collapse towards each other in the merging process, they trap their external fronts between them; these fronts are inserted into the final merged vortex, where they form a central, nearly parallel, sheared velocity strip, sen- sitive to barotropic instability. As a result, this strip breaks up into an alley of small vortices. Subsequently, these small vortices may undergo merger and grow in size in the core of the large merged vortex. The number of small trapped vortices decreases correspondingly. Finally, a single or two small vortices remain. These processes are analysed using a numerical model of the surface quasi-geostrophic equations. The sensitivity of this process to the initial vortex characteristics is explored. A parallel is drawn between this problem and the instability of a rectilinear strip of temperature with a central gap. The application of this problem to the Ocean is discussed.

title: Stable isotope ratios of C and N in cold seep fauna from the Gulf of Guinea collected during the WACS cruise (2011)

description: During the 2011 WACS cruise of RV Pourquoi Pas ? (Olu 2011, https://doi.org/10.17600/11030010), biomass-dominant fauna was sampled in several cold seep sites of the Gulf of Guinea (Regab, Guinness, Baboon and Worm Hole pockmarks) as well as in the Congo River deep-sea fan (lobes A, C and D). Stable isotope ratios of carbon and nitrogen of 406 samples belonging to &gt;20 taxa and sediments were measured. Samples were prepared for analysis at the UMR6197 BEEP (Biologie et Ecologie des Ecosystèmes marins Profonds, Ifremer, Centre de Bretagne, France; https://www.umr-beep.fr/). Analytical measurements were performed at Geotop’s light stable isotope geochemistry laboratory (UQAM, Montreal, Canada). This data was used for the analyses underlying the paper "Environmental parameters and biotic interactions influence food web structure in deep-sea cold seeps from the Gulf of Guinea", by Loïc N. MICHEL, Marie PORTAIL, Dominique A. COWART, Pen-Yuan HSING, Lucie PASTOR, Karine OLU & Jozée SARRAZIN. The dataset consists of two files: one containing the data itself, and one describing all used terms (measurements or metadata).

title: ROV3G 2021 database: geophysical data on the continental shelf offshore Santo Stefano al Mare and San Lorenzo al mare, Liguria, Italy.

description: ROV3G scientific cruise is dedicated to the morpho-tectonic study of the ligurian shelf, through the acquisition of bathymetric data and optical images with HROV Ariane. This cruise took place on R/V Europe in october 2021, and constituted a pedagogic project for the students of Master 3G Recherche, Géologie et Géophysique, of Université Côte d'Azur (UCA), attached to Géoazur lab. The M2 students were in charge of the scientific project, they determined the goals of the cruise, took part in the acquisition and interpretation of the data. During the 3 days cruise, we acquired bathymetric data at shallow depth on the continental shelf offshore Santo Stefano al Mare and San Lorenzo al Mare, along the Ligurian coast. The bathymetry on the continental shelf exhibits morphologies that are probably related to the Flyschs formation that is outcroping onshore (Stani et al., 2010), and that is partially capped by late quaternary deposits (as identified in seismic data and interpreted in Bozzano et al., 2006). Ridges identified as paleo-shorelines (paleo-beaches?) have been investigated with HROV ariane whose navigation is also published here. Videos are available on video.ifremer.fr Here we publish two bathymetric grids at high-resolution, calculated from the ME70 multibeam echosounder of R/V Europe, using GLOBE software (Poncelet et al., 2022). The shallowest part of the plateau is gridded in a 5 m digital elevation model (DEM), while the entire survey area is gridded at 10m resolution. The back-scatter maps, gridded at 6 m, produced with Sonarscope software (Augustin et al., 2022), are also available (raw and compensated). All grids are in WGS84 (EPSG:4326). The cruise report (written in french) is also available.

title: Seagrass Meadows in The Greek Seas

description: Combined use of optical (satellite imagery), and acoustic (sidescan sonar) remote sensing techniques, as well as in situ methodologies (visual census; SCUBA diving, Towed Underwater Cameras, and Remotely Operated Vehicles) was employed to map the spatial distribution of seagrass habitats in the coastal waters of the Hellenic territory. Seagrass meadows were recorded at approximately 70% of the Hellenic coastline (Eastern Ionian, Aegean and Levantine Seas), and their surface area exceeded 2,749.09 km2. Posidonia oceanica is -by far- the dominant seagrass species of the Hellenic seas, covering the vast majority of seabed at depths between the shoreline and 25 – 30 m (or deeper in insular areas), followed by the species Cymodocea nodosa, Zostera noltei, and Halophila stipulacea, which, however, presenting local presence and limited areal extent. Habitat suitability in terms of the seabed spatial extent that is available for the growth of seagrass meadows (i.e., the spatial extent of coastal areas between the shoreline and the isobath of 20m) and the seawater clarity conditions are highlighted as the critical factors for the formation of well-structured and extensive meadows. The results of this study are of great importance and usefulness for the effective management and conservation of valuable marine ecosystems.

title: Dissolved cobalt and manganese in the East China Sea

description: This dataset describes the dissolved cobalt and manganese distributions in the East China Sea. Other parameters such as salinity, water temperature, potential density, dissolved oxygen, and nutrient (nitrate, phosphate, and silicate) concentrations are also included. Seawater samples used for generating this dataset were obtained during the KS-15-6 cruise onboard R/V Shinsei Maru between July and August 2015 (Stn1 to Stn15), and during the KH-15-3 cruise onboard R/V Hakuho Maru in October 2015 (F1, D4, B8, and I1). Dissolved cobalt concentrations were determined using cathodic stripping voltammetry at the University of Tokyo and by using inductively coupled plasma - mass spectrometry (ICP-MS) at Kanazawa University, Japan. Meanwhile, dissolved manganese concentrations were determined using ICP-MS at both the University of Tokyo and Kanazawa University. All samples were irradiated with ultraviolet light before analysis.
