The dataset on offshore active licences for Oil and Gas exploitation and exploration in the EU was created in 2014 by Cogea for the European Marine Observation and Data Network (EMODnet). It is the result of the aggregation and harmonization of datasets provided by several EU and non-EU sources. It is updated every year, and is available for viewing and download on EMODnet - Human Activities web portal (www.emodnet-humanactivities.eu). It contains polygons representing active offshore licenced areas in the following countries: Croatia, Cyprus, Denmark, France, Germany, Ireland, Italy, Malta, Netherlands, Norway, Poland, Spain and United Kingdom. Where available each polygon has the following attributes: country, code, name, type (exploitation, exploration, exploitation and exploration, other, N/A), licensing round (it includes also pending applications in France and Spain), area (square km), area info (it indicates if the area value is original from the source or has been calculated), starting year, ending year, operator or administrator. Compared with the previous release, 'Exploitation, exploration' new type of licence has been added. Italy's exploration licences are all temporarily suspended.

We genotyped 1680 thornback ray Raja clavata sampled in the Bay of Biscay using a DNA chip described in Le Cam et al. (2019). After quality control 4604 SNPs were retained for identifying potential sex-linked SNPs using three methods: i) identification of excess of heterozygotes in one sex, ii) FST outlier analysis between the two sexes and iii) neuronal net modelling. Genotype coding: 0 homozygous for major allele, 1 heterozygous, 2 homozygous for minor allele. Flanking DNA sequences of SNPs identified with methods i) and ii) are also provided.  

The product "BathyElli surfaces v2.1" contains the surface realisation of the ellipsoidal height at the reference date of 1 January 2000 of the characteristic tidal levels corresponding to : - Highest Astronomical Tide (HAT): "BathyElli v2.1 HAT / ell" ; - Mean Sea Levels (MSL): "BathyElli v2.1 MSL / ell"; - Lowest Astronomical Tide (LAT): "BathyElli v2.1 LAT / ell"; - Chart Datum (CD) vertical sea level reference for each tidal zone: "BathyElli v2.1 HZ / ell".

GLODAP is an internally consistent data product for interior ocean “carbon relevant” variables, but in practice this means “everything that is measured from water samples” taken on hydrographic cruises that takes measurements of biogeochemistry, including inorganic carbon measurements. GLODAP was first published in 2004, and a new massively increased version, GLODAPv2, was published in 2016. A new version – GLODAPv2.2018 – will be published in early 2019. GLODAP have three main products: 1) A collection of individual cruise file in a consistent format and 1st level QC, 2) A product that has been bias corrected through 2nd level QC procedures, and 3) an interpolated product on a regular grid.

Climatology of near-inertial currents. Global climatology of near-inertial current characteristics from satellite-tracked drifters. Data analysed : 8500 near-surface satellite-tracked drifter trajectories with drogues attached at 15 m depth.

The West Gironde Mud Patch (WGMP) is a mud deposit located 25 km from the mouth of the Gironde Estuary in the Bay of Biscay. This 4-metre-thick clay-silt feature, which extends over an area of 420 km2, is found at depths between 30 and 80 meters. The main objectives of the JERICObent7 cruise, in July 2019, were to characterise the evolution of the WGMP’s benthic ecosystem in terms of its sedimentary, biogeochemical and ecological properties and to reconstruct climate variations and identify potential anthropogenic impacts over the last few centuries. To this end, a precise chronological framework was established for the sedimentary archives of the last few decades using 210Pbxs (T1/2 = 22.3 years). Interface cores were collected at stations 1, 3 and 4 along a cross-shelf transect. Twin Kullenberg cores were collected at sites 3 and 4 for geochemical (KGL) and palaeoceanographic (JB7-ST) investigations. Each interface core was carefully extruded at 0.5 cm intervals from the top of the core to 4 cm, and then at 1 cm intervals until the bottom was reached. Kullenberg cores were only collected at sites 3 and 4. Depending on their intended use, the Kullenberg cores were sampled at different resolutions, the depth of each sediment layer corresponded to the depth from the top of the core. These layers were then used to determine the dry bulk density and radioisotope activities of interest (210Pb, 226Ra,  228Th, 137Cs, 40K). Excess 210Pb was used to establish the realignment and chronological framework of the interface and Kullenberg cores.

There are at least a dozen small hyper-turbid estuaries facing the Bay of Biscay, geographically situated between the two major estuaries of the Gironde and the Loire. MAGEST and SYVEL high-frequency multi-site monitoring revealed that the Loire, and to a lesser extent the Gironde, are subject to summer hypoxia. These observations raised the question of the potential occurrence of hypoxia in the small estuaries in between, motivating an investigation of dissolved oxygen in one of them, the Charente estuary. Oxygen and salinity sensors were placed at L'Houmée (2019), Tonnay-Charente (2018; 2019), Rochefort (2020; 2021; 2022), Martrou (2020) during summer, the most critical period for dissolved oxygen; a multiparameter probe was placed at Tonnay-Charente from April to November 2020. Longitudinal investigations along the estuary axis were also carried out during the summers of 2018 and 2019. All the measurements were acquired at 0.5 ± 0.2 meters below the surface. The dataset enabled us to identify the occurrence of summer hypoxia and an oxygen depletion zone in the Charente estuary. These results resulted in the implementation of high-frequency monitoring at Tonnay-Charente, operational since November 2020.

The product contains a description of submarine cables and pipelines brought to the attention of Shom on French areas of responsibility. These are 2D linear objects of the seabed that divide into two categories: • The submarine cables: these are cables placed on the seabed where electricity or information (telecommunication) flows. They represent the vast majority of objects (more than 90%); • Emissaries and submarine pipes: these are pipes that allow the discharge, sampling or circulation of fluids.
