Presence of deep-sea mining exploration zones on the North Atlantic (18°N to 76°N and 36°E to 98°W). These areas correspond to the three polymetallic sulphides exploration contracts on the Mid-Atlantic Ridge, attributed to Poland, France and Russia. Each of the three contract areas is divided into 100 squares of 10km by 10km. Source polygons originated from the International Seabed Authority. The presence (value=1) of deep-sea mining was extracted in 25km * 25km gridsquares. 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.

Localization of professional organizations linked to shellfish farming within Euroshell project

Agencies education in marine trades geolocalized to municipality. This information was produced as part of the initial assessment of the MSFD. Referent expert Sophie Devergie. WARNING: the spatial structure of the data must be improved because it contains superpositions of points (several training agencies per commune). Here the tool "Representation" of ArcGIS was used to facilitate the mapping of the data that does not meet basic standards of the topology. Ultimately, the quality of the data can be improved by refining the address geolocation.

Under the EU Water Framework Directive (2000/60/EC), among the biological parameters involved in the assessment of coastal water bodies, the quality element "phytoplankton" is defined. This indicator Phytoplankton is made up of several indexes including a biomass index and an abundance index. Oxygen balance appearing among the elements of physicochemical quality selected for the classification of the ecological state of coastal water bodies. The quality element "benthic invertebrates" is also part of the biological parameters involved in the assessment of these water bodies.

Shellfish farming areas can have different meanings. Sometimes their identification is prescribed and used for health classification of production areas. In Euroshell project, the choice was made to map the production areas whose identification makes sense for both scientists and professionals. A limited number of areas is then showed, often corresponding to a hydrographic reality. Indeed, the shellfish industry is mainly installed in estuaries, river mouths, bays, fjords, estuaries or lagoons. This map shows the shellfish production sites, which include several areas. Some information is given on species produced, the number of companies and / or concessions and / or producers, the approximate amount of production.
