title: Geochemistry of hydrothermal fluids at the Lucky Strike Hydrothermal Field data from the EMSO-Azores observatory, 2025

description: High temperature hydrothermal fluids are collected by gas-tight fluid sampler manipulated and triggered by the hydraulic arm of the submarine vehicle (HOV Nautile). Several hydrothermal vents are sampled, namely : Aisics, Eiffel tower, Montsegur, Isabel, Sintra, Y3, White Castle, Cypress, South Crystal, Crystal, Capelinhos, Roldan.
Several chemical analyses are performed aboard the research vessel: such as salinity and d20/20 by refractometer, Conductivity, salinity and total dissolved solid (TDS) by electrode (standard solution at 1413 µS/cm), pH and Eh by electrode (pH standard 4.01 and 7; Eh standard solution at 220mV), iron concentration by photometer (up to 5 ppm), H2S and total S concentrations measured by electrode (AquaMS, amperometric method) at measured pH value.

title: ORHAGO beam trawl survey catch data : Bentho-demersal assemblages of the Bay of Biscay (North-eastern Atlantic) from 2007 to present.

description: The ORHAGO campaigns (Observation of the benthic aquatic resources of the Golfe de Gascogne) are designed to collect data on the composition, distribution and change in relative abundance of benthic fish fauna on the continental shelf (depth &lt;100m) in November to December on a yearly basis. The ORHAGO survey was initiated in 2007 with the objective of developing a fishery-independent abundance index for flatfish species, with a particular focus on the common sole (Solea solea) of the Bay of Biscay. In accordance with the ICES-agreed gear for flatfish abundance surveys, ORHAGO employs a 4-meter-beam trawl with a chain mat, 50-millimeter mesh in the net, and 40-millimeter mesh in the cod-end. The sampling plan was designed to ensure full coverage of the common sole habitat in the Bay of Biscay during a period (November-December) for which fish behavior and distribution was suitable for obtaining an unbiased abundance index (young fish move offshore when coastal waters become colder and before the concentrations of the spawning season). The sampling design is a systematic sampling with 49 reference stations. The sampling design was validated in 2013 by the ICES Working Group on Beam Trawl Surveys (WGBEAM). Since 2013, the ORHAGO survey has been used to assess the status of the Bay of Biscay common sole stock (WGBIE, Working Group for the Bay of Biscay and the Iberian Waters Ecoregion).

title: ROCCHSED 2022 cores dataset : contaminants (metals, PAH, PCB) concentrations measured in dated sediment cores from the bay of Biscaye (France)

description: ROCCH, the French Chemical Contaminant Monitoring Network, regularly provides data for assessing the chemical quality of French coastal waters. Concentrations of trace metals and organic compounds are measured in integrative matrices (bivalves and sediments).
Surface sediment samples are collected from 200 to 250 monitoring stations in the English Channel, the Bay of Biscay and Mediterranean lagoons every six years. Results concerning approximately 140 historical and emerging chemical substances (metals, PAHs, PCBs, PBDEs, PFAS …) are submitted to international databases of the Regional Sea Convention (OSPAR for the North East Atlantic and the Barcelona Convention for the Mediterranean) and disseminated to public stakeholders.
During the ROCCHSED campaign in spring 2022, three sediment cores, each forty to fifty centimetres long, were collected from three different sites in the Bay of Biscay. Horizons of one to two centimetres in length were dated, sieved and freeze-dried for chemical analysis. The concentrations of metals, PAHs and PCBs were determined in horizons aged from over 150 years to the present in order to define the reference concentration of natural levels and describe the temporal profile of contamination.

title: SMOS SMAP high resolution SSS maps near Greenland

description: Users of satellite Sea Surface Salinity (SSS) products stress the importance of temporal and spatial resolution for the study of processes especially in river plumes.
The  Ocean Salinity Center of Expertise for CATDS (CATDS CEC-OS) has derived SSS maps optimized for keeping high temporal SSS variability around Greenland from SMOS and SMAP satellite data.
As for SMOS SMAP high resolution ‘HR’ product generated by CATDS CEC in tropical and sub tropical regions (Boutin et al. 2022), the Greenland HR products are built using a temporal optimal interpolation, grid node per grid node. This interpolation is done simultaneously with the estimation of the across-track SSS biases [Boutin et al., 2021], but instead of a gaussian covariance function in the temporal domain, an exponential function is used. The use of an exponential function allows an improvement of the spatial contrasts in regions with high variability. No spatial smoothing is applied on the original level 2 SSS products so that the effective spatial resolution of SSS at each grid point is close to 50km. 
SMOS and SMAP Level 2 SSS entering in the temporal optimal interpolation are :
 - SMOS SSS from ESA DPGS version 700
 - SMAP SSS (40km products) version v5.3 provided by RSS
The products issued by this processing (version 1 HR products) have been used by Reverdin et al. (2025). 
Products are delivered on a regular 0.25° grid over the period [2015-2022].
Feedbacks from users about the quality of these new experimental products are very welcome and essential for the CATDS expertise center to improve future versions.

title: Image-based ecological assessment of deep-sea sponge, coral and other cnidarian assemblages through a morpho-functional approach : dataset and script repository

description: This DOI includes datasets compiling: matrices on megabenthos density, density of morpho-functional groups of sponges and cnidarians, environmental variables (per 200 m² sampling unit), and on the presence/absence of morphological traits for sponges and cnidarians; as well as supplementary information related to the publication ‘Image-based ecological assessment of deep-sea sponge, coral and other cnidarian assemblages through a morpho-functional approach’ (in preparation).
The data were collected as part of the PAMELA project (Bourillet et al., 2013) during the PAMELA MOZ01 (Olu, 2014) cruises aboard the R/V L'Atalante, and PAMELA MOZ04 (Jouet & Deville, 2015) aboard the R/V Le Pourquoi Pas ?, enabling the exploration of four seamounts (Glorieuses and Sakalaves, Jaguar and Hall Banks platforms) and the Bassas da India Island slope terrace. Data were also collected on three outer slopes (east, north and west) of the island of Mayotte during the BIOMAGLO cruise(Corbari et al., 2017) aboard the R/V L'Antea.  The images were captured from towed camera transects (SCAMPI, French IFREMER fleet).
The megabenthic community dataset comprised 99 taxa of varying taxonomic resolution, identified from 9,614 images using the online image annotation platform BIIGLE 2.0 (Langenkämper et al., 2017). Details of the method used to identify and classify megafauna in the images are described in Hanafi-Portier et al. (2021), and those of the selection and curation of the final megabenthic community database in Hanafi-Portier et al. (2024).
Details of the methodology used to produce the density matrices of morpho-functional groups of sponges and cnidarians are available in the Materials and Methods section of the publication ‘Image-based ecological assessment of deep-sea sponge, coral and other cnidarian assemblages through a morphofunctional approach’ (in preparation).
Details on the methodology used to produce the environmental dataset are available in the Materials and Methods section of Hanafi-Portier et al. (2024).
The datasets were used to assess the benefit of the morpho-functional characterisation in the assessment of (1) sponges and cnidarians diversity and spatial patterns at multiscales, (2) the environmental drivers shaping these morphological spatial structure, and (3) their potential structuring roles on the associated megafaunal communities overall.

title: Imagery reconstructions in 3D of 14 active edifices at the Lucky Strike hydrothermal vent field (Mid Atlantic Ridge).

description: Fourteen edifices of the Lucky Strike Hydrothermal vent Field (LSHF) were suveyed by imagery to create 3D reconstructions : Bairro Alto, Crystal, Cypres, Helene, Isabel, Pico, Sintra, Snowman, South Crystal, Timor, Tour Eiffel, Vazydon, White Castle and Y3. They are located around the lava lake of the main Lucky Strike Hydrothermal Vent Field (LSHF) and the coordinates are shown in the table below. The edifices have been surveyed with the remotely operated vehicle Victor6000 for inter-annual monitoring during the 2024 Momarsat cruise. Videos were collected during dives 862-3 (South Crystal, Timor, Vazydon), 863-4 (Isabel, Sintra, Y3), 864-5 (Bairro Alto, Crystal, Helene, Snowman, Pico, White Castle) and 866-7 (Cypres, Tour Eiffel) with a forward-looking HD camera and video sequences were used to build a 3D model of the edifice using structure-from-motion techniques. A first series of data includes images extracted every 3 seconds from the videos using the Matisse preprocessing software. The images are time-stamped and linked to a navigation file, which is generated by interpolating navigation data at the corresponding timestamps. A second series of data includes 3D textured models of the edifices (obj format) together with the a kml file for georeferencing, built using the 3DMetrics software. The ROV navigation files (.txt) are provided separately and were processed from raw acoustic data using the ROV trajectory information to smooth the final navigation.

title: Bathymetry of the lagoon and hoa of Reao, Tuamotu Archipelago

description: Bathymetric data were acquired in Reao Atoll, a semi-enclosed atoll lagoon without reef pass but connected to ocean through numerous shallow spillways (known locally as "hoa") along its southern rim. This data was acquired as part of the GAIA (ManaGement strAtegy evaluatIon for small-scale fisheries in Atoll lagoons) project, which evaluates the sustainability of giant clam exploitation within the context of climate change.
The lagoon of Reao is composed of three basins with varying depths (the NW basin being the shallowest and the SE basin the deepest). Bathymetric data were acquired from 29/04/2022 to 04/05/2022, within the lagoon with a Multibeam echo sounder IWBMS (NORBIT), and resampled at 5 m spatial resolution. Satellite-derived-bathymetry (SDB) at 10 m spatial resolution was established by coupling this bathymetric data with a Sentinel-2B image captured on 26/09/2020 and using the « Iterative Multi Band Ratio » technique (detailed methodology is described in Quéré et al. 2025). Finally, bathymetric surveys were carried out to characterize the nine most functional hoa of the atoll. One bathymetric survey was carried out in the longitudinal section of each hoa, while one or two surveys were carried out in their cross-sections.

title: Past trajectory of a Northwest Europe socio-ecosystem at the land-sea interface: Case study of the northern watersheds of the Bay of Brest over the last 150 years

description: The Bay of Brest (BB) is a macro-tidal estuarine environment that has been exposed to strong anthropogenic pressures over the past few decades, especially after the Second World War. This makes the BB an ideal site for studying coastal ecosystem transformations since the Industrial Revolution. We analysed 5 sediment cores collected in 2 key BB areas with varying exposure to marine hydrodynamic processes: i) Elorn sector (3 cores) and ii) Bay of Daoulas (2 cores) in the inner BB, close to the mouth of the Daoulas river. Our study used palynological (pollen and dinoflagellate cysts) and benthic foraminiferal assemblages, sedimentological data, and elemental geochemistry, at a very fine temporal resolution (Daoulas core: 2-year resolution; Other cores: 2 to 16-year resolution). Working at a local spatial scale (i.e. BB) reveals robust correlations between the different driving forces and environmental changes at a high temporal resolution (i.e. sub-decadal) over the last 150 years. Our statistical analyses of these paleoecological time series reveal major breakpoints, specifically 4 key threshold periods: 1925–1938, 1960–1967, 1980–1987, and 2005, which are essential for understanding temporal changes in protist communities and BB landscapes through time. By combining these findings with a reanalysis of regional precipitation patterns (modelling approaches using meteorological reanalyses), nutrient concentration data, and historical accounts of land-use practices and industrial/mining/Second World War activities, we can identify the main drivers of coastal ecosystem transformations. Our findings emphasize the strong influence of agricultural practices on trophic changes and water quality decline in the BB, with coastal observatory series showing a notable increase in toxic algal blooms since the 1980s.

title: One snack before the road: Egg cannibalism in post-spawning Downs herring

description: This dataset gathers information about the biometry, reproduction status, and stomach content analysis of adult Downs herring collected by professional fishermen during the 5 weeks (November - December 2022) of the 2022 winter spawning season. Herring migrates to the Eastern English Channel in winter to spawn. Earlier, it feeds during spring and summer in the north of the North Sea, and stops feeding when gonad maturation starts. Consequently, feeding resumption after spawning is crucial. The project leading to this dataset investigated the impact of reproduction on feeding behavior by monitoring jointly reproductive status of fish (through  gonadosomatic index calculation) and diet resumption (by analyzing stomach content both with visual identification of preys and automated analyses of preys images), notably monitoring the changes in stomach vacuity over the 5 weeks. 
This dataset confirms that (1) automated image analysis of preys is powerful to document herring diet, (2)  pre-spawning individuals stop feeding (as all stomachs are empty), and that feeding resumption occurs only after spawning and (3) that cannibalism on eggs is a strategy adopted by post spawning herring to cope with the need of a quick energetic input, before engaging in back migration.

title: Dataset from an in situ mesocosm experiment evaluating the effects of a simulated marine heatwave on the structure and composition of the plankton food web in a Mediterranean coastal lagoon

description: Coastal ecosystems are particularly affected by marine heatwaves (MHW) which are predicted to become more frequent and stronger by the end of the century. These extreme events potentially impact marine organisms including plankton communities and their dynamics. 
The present study aims to provide a more comprehensive understanding of how each plankton food web component and their interactions will respond to a simulated MHW.
For this study, an in situ mesocosm experiment was carried out from May 24th to June 12th, 2019, in the Thau lagoon on the French Mediterranean coast (43.414699N, 3.688125E). Two conditions were applied in triplicate. One condition simulated a MHW of + 3 °C above the natural lagoon temperature for 10 days, followed by a return to the natural lagoon temperature for the next 10 days (MHW condition), while the other condition maintained at natural lagoon temperatures throughout the experiment (control condition).
Over the 20 days of experiment, the sampling of plankton communities in both conditions was conducted daily or every two days to study their responses to a simulated MHW. 
The abundance of virus-like (hereafter referred to as virus), heterotrophic bacteria, cyanobacteria, pico- and nanophytoplankton eukaryote population were identified using flow cytometer in cells·mL-1. Phytoplankton and ciliates abundances (cells·mL-1) and taxonomic composition were identified by an inverted microscope. Abundance of heterotrophic nanoflagellates was counted by an epifluorescence microscope in cells·mL-1.
It should be noted that in some of the related papers, some groups of the same organisms have been grouped within a single group (example, two groups of virus-like).
