Gironde estuary environmental parameters and SPM maps generated from 41 Landsat-8/OLI and Sentinel-2/MSI images acquired over the period 2013-2018. Except bathymetry and daily river discharge data, that are accessible on public platforms, the dataset includes all of the time seris used in the publication: Analysis of suspended sediment variability in a large highly-turbid estuary using a 5-year-long remotely-sensed data archive at high resolution, Journal of Geophysical Research: Oceans, DOI:10.1029/2019JC015417.

Tracking data of 7 grey seals were obtained from the deployment of Fastloc GPS/GSM tags developed by the Sea Mammal Research Unit (UK). Full tag description is available at: http://www.smru.st-andrews.ac.uk/Instrumentation/GPSPhoneTag/. The tags include a wet-dry sensor from which haulout events are recorded, a pressure sensor providing detailed dive data, as well as a Fastloc GPS recording irregular locations when the seal is not underwater. Data is stored onboard and transmitted via the GSM network when the seal is in the reception range. The data provided here are the individual GPS locations of the seals fitted with these tags for an average duration of 135 days.

Understanding the dynamics of species interactions for food (prey-predator, competition for resources) and the functioning of trophic networks (dependence on trophic pathways, food chain flows, etc.) has become a thriving ecological research field in recent decades. This empirical knowledge is then used to develop population and ecosystem modelling approaches to support ecosystem-based management. The TrophicCS data set offers spatialized trophic information on a large spatial scale (the entire Celtic Sea continental shelf and upper slope) for a wide range of species. It combines ingested prey (gut content analysis) and a more integrated indicator of food sources (stable isotope analysis). A total of 1337 samples of large epifaunal invertebrates (bivalve mollusks and decapod crustaceans), zooplankton, fish and cephalopods, corresponding to 114 species, were collected and analyzed for stable isotope analysis of their carbon and nitrogen content. Sample size varied between taxa (from 1 to 52), with an average of 11.72 individuals sampled per species, and water depths ranged from 57 to 516 m. The gut contents of 1026 fish belonging to ten commercially important species: black anglerfish (Lophius budegassa), white anglerfish (Lophius piscatorius), blue whiting (Micromesistius poutassou), cod (Gadus morhua), haddock (Melanogrammus aeglefinus), hake (Merluccius merluccius), megrim (Lepidorhombus whiffiagonis), plaice (Pleuronectes platessa), sole (Solea solea) and whiting (Merlangius merlangus) were analyzed. The stomach content data set contains the occurrence of prey in stomach, identified to the lowest taxonomic level possible. To consider potential ontogenetic diet changes, a large size range was sampled. The TrophicCS data set was used to improve understanding of trophic relationships and ecosystem functioning in the Celtic Sea. When you use the data in your publication, we request that you cite this data paper. If you use the present data set (TrophicCS) for the majority of the data analyzed in your study, you may wish to consider inviting at least one author of the core team of this data paper to become a collaborator /coauthor of your paper.

The BenthOBS dataset includes long-term time series on marine benthic macrofauna, since 1967, along the whole French metropolitan coast. It includes 20 sampling location. BenthOBS aims to establish a national network for the observation of macrozoobenthos. In a context of global change, It is essential to have time series capable of highlighting and understanding ongoing changes in the specific diversity within communities and their consequences on the functioning of marine ecosystems. The BenthOBS network provides the scientific community and stackers with validated data on the following parameters: specific abundance, sediment size composition, sediment organic matter, sediment C content, sediment N content.

The Pélagiques Gascogne (PELGAS, Doray et al., 2000) integrated survey aims at assessing the biomass of small pelagic fish and monitoring and studying the dynamics and diversity of the Bay of Biscay pelagic ecosystem in springtime. PELGAS has been conducted within the EU Common Fisheries Policy Data Collection Framework and Ifremer’s Fisheries Information System. Details on survey protocols and data processing methodologies can be found in Doray et al., (2014, 2018a). This dataset comprises the biomass (in metric tons) and abundance (in thousands of individuals) of small pelagic fish estimated during the PELGAS survey in the Bay of Biscay in springtime. The dataset also includes the estimation coefficient of variation, derived based on the hydroacoustic methodology described in Doray et al. (2010), and the survey area. Those estimates have been validated by the ICES WGACEGG group and provided to the ICES WGHANSA group for stock assessment purposes. Data have been used in Doray et al., 2018b.

The ICES Working Group on Fisheries Benthic Impact and Trade-offs (WGFBIT) has developed an assessment framework based on the life history trait longevity, to evaluate the benthic impact of fisheries at the regional scale. In order to apply this framework to the Mediterranean sea, several Mediterranean longevity databases were merged together with existing North-East Atlantic ones to develop a common database. Longevity was fuzzy coded into four longevity classes: <1, 1-3, 3-10 and >10 years. Both benthic mega and macrofauna organisms are included in this dataset. Further details about both the purpose and the methodology may be found in ICES (2022) and Cuyvers et al. (2023). The result of the final dataset merging is one dataset containing the fuzzy coded average longevity (and standard deviation) for 2264 taxa and for each, the number of databases used. 

SUCHIMED 2021 is the 10th campaign for monitoring chemical contamination and its evolution in the Mediterranean Sea. It has been designed as a platform supporting various surveillance and research activities, with the main pillar being the RINBIO network, which involves active biosurveillance through mussel caging. Regarding chemical contamination, the main results of this campaign are as follows: In Occitania region: - Chronic presence of DDT for 20 years. - Detection of terrigenous markers (Mn, As) between the mouths of the Aude and Hérault rivers, along with contamination of sediments near Port-La-Nouvelle by HAP and TCE (Pt). In PACA region: - PCB markers detected between the Rhône River and Marseille (in all matrices), originating from multiple sources with no significant changes over the past 20 years. - HAP contamination in sediments of the industrial-port zone in Fos. - Presence of TBT at the Carry-le-Rouet station above ecologically acceptable concentrations (EAC), to be confirmed in the next campaign. - Detection of metallic elements and HAP in sediments near the Marseille urban area, partly in plankton, along with TCE near the Cortiou wastewater treatment plant outfall. - Chronic marking of PCB, HAP, metals (Hg, Pb, Cu, TCE), PBDE, and/or organotin compounds (TBT) in Toulon Bay, showing no significant temporal trend over two decades for the first five compounds. - Detection of Cr, Mn, and Ni in the water column and HAP in sediments near the Var River mouth, with differences in contamination between matrices raising questions about organic matter origin. - Metal (including Pb) and HAP marking in the water column and sediment in Villefranche Bay. Around Corsica: - Strong influence of the island's geological background (i.e., high Cr and Ni content) on obtained concentrations. - Chronic marking of Cu in the water column in the ports of Porto-Vecchio and Bonifacio, stable over time, with HAP, metals (Hg, Pb, Zn), and to a lesser extent, PCB detection in Bonifacio sediment. - Marking of HAP and TCE in the sediment of the Bastia coastline. - Detection of Pb and TCE at the Golo River mouth. - Contamination of the Canari site with metals (Cr and Ni in the water column, Cu in sediment), and notably, confirmed ecotoxicity likely linked to these elements. The 2021 campaign highlighted the feasibility of researching effects on caged mussels using biomarkers. Lysosomal markers, less sensitive to trophic differences, proved to best reflect the general stress state of organisms related to their contamination. The study of trophic transfers appears to confirm the decrease in most metallic elements (Cr, Cu, Fe, Mn, Ni, Pb) and HAP, bioamplification of Hg and PCB, and specific bioaccumulation of certain elements by organisms (e.g., As or Zn by mussels, HAP by plankton). Finally, the campaign revealed the presence of micro and mesoplastics at almost all sampled sites. The measured microplastic values align with concentrations observed in the western Mediterranean, with a trend towards reduction based on available 10-year data.

As part of the marine water quality monitoring of the “Pertuis” and the “baie de l’Aiguillon” (France), commissioned by the OFB and carried out by setec énergie environnement, three monitoring stations were installed. Two of them were set up at the mouths of the Charente and Seudre rivers on February 6 and 27, 2019, respectively, while a third was deployed in the Bay of Aiguillon on March 24, 2021. The dataset presented here concerns the station installed in the Bay of Aiguillon. Measurements are organized into .csv files, with one file per year. Data is collected using a WiMO multiparameter probe, which records the following parameters: •    Temperature (-2 to 35 °C) •    Conductivity (0 to 100 mS/cm) •    Pressure (0 to 30 m) •    Turbidity (0 to 4000 NTU) •    Dissolved Oxygen (0 to 23 mg/L & 0 to 250 %) •    Fluorescence (0 to 500 ppb)
