Landslides and gravitational features mapped within French metropolitan EEZ at 1 : 250 000 in the framework of work-package 6 of the european project EMODNet Geology phase 2.

90th percentile calculated during the productive period of the WFD (March-October) from 2015 to 2020, from the MODIS Chl-a algorithm processed by OC5 IFREMER/ARGANS (Gohin et al 2002, Gohin 2011).

Since 2001, an annual stock assessment of Manila (Ruditapes philippinarum) and European (Ruditapes decussatus) clams has been carried out in March in the Gulf of Morbihan and the Noyalo River. The objectives of this survey are : 1) estimate by direct assessment, the biomass of the stock and its geographical distribution; 2) estimate the exploitable biomass and exploitation potential for the sampled sites in particular, in areas reserved for professional fishing; 3) to establish a diagnosis, with a medium-term vision, on the state of the stock; 4) to propose the implementation of appropriate management measures. Two cruises were also carried out in 1996 and 1997.

A world deep displacement dataset, named ANDRO, after a traditional dance of Brittany meaning a swirl, comprising more than 1300 000 deep displacements, has been produced from the Argo float trajectory data ('traj' files). ANDRO dataset was completed over the period 2000-2009, then was partially but yearly updated since 2010. For detailed information and status of the last released ANDRO product, please visit the dedicated Argo France web page: https://www.umr-lops.fr/SNO-Argo/Products/ANDRO-Argo-floats-displacements-Atlas One important feature of ANDRO is that the pressures measured during float drifts at depth, and suitably averaged are preserved in ANDRO. To reach this goal, it was necessary to reprocess most of the Argo raw data, because of the many different decoding versions (roughly 100) not always applied by the DACs to the displacement data because they were mainly interested in the p,t,S profiles. The result of our work was the production of comprehensive files, named DEP (for 'déplacement' in French), containing all the possibly retrievable float data.

This annual statistics at 500m horizontal resolution was produced from the archived time series of MARS 3D physics model hindcast runs along French Atlantic Coast. The variable that is available here is the Kinetic Energy induced by currents caused by tide, water density gradients and action of winds. The formula used for the Kinetic Energy calculation is 0.5mv², where m is the density of seawater (1027 kg.m-3) and v is the current-induced velocity. Values are expressed in N.m-2 (Newton per square meter). The vertical level is the seabed.

Distribution of three bathymetric terrain variables (depth, slope and Bathymetric Position Index) on the North Atlantic (18°N to 76°N and 36°E to 98°W). This dataset originated from three source layers (3km * 3km resolution) computed within the work package 3 of EU ATLAS project, and based on the EMODnet Digital Bathymetry portal and the General Bathymetric Chart of the Oceans (GEBCO). From these source layers, the mean depth (m), slope (degree) and BPI (no unit) were calculated for each 25km * 25km gridsquare. This dataset was built to feed a basin-wide spatial conservation planning exercise, targeting the deep sea of the North Atlantic. The goal of this approach was to identify conservation priority areas for Vulnerable Marine Ecosystems (VMEs) and deep fish species, based on the distribution of species and habitats, human activities and current spatial management.

This bathymetric data package is being made available as part of the de-risking study to be carried out in the Gulf of Lion for the award of a "commercial floating wind turbine" call for tenders by 2022. It includes bathymetric digital models covering French territorial waters. Raw data have been acquired during oceanographic campaigns: AM-MED-1, BASAR2, BASAR3, RHOSOS et STRATAFORM 1.

The objective of the PELGAS cruise is to monitor distribution and abundance of pelagic species fished in the Bay of Biscay, using two direct evaluation methods: acoustics and spawning estimates. The cruise was conducted in coordination with France, Spain and Portugal, in the framework of the European council regulations (EC No 1543/2000 of 29 June 2000 and No 1639/2001 of 25 July 2001).
