Localisation of marine geological and biological samples, stored in the biology and geology ocean database managed by IFREMER (BIGOOD, BIology and GeOlogy Ocean Database).

The data is provided as a layer of points representing the samples taken (operations) in the French Mediterranean. The lists of species identified corresponding to these sample points are in the Biocean database.

Occurrence data of strandings of marine mammals collected by the correspondents of the National Stranding Network (date, position, species) in metropolitan France in 2014-2020.

Layer of Polygons representing the distribution of organisms described in the bibliography by Maurin (1962) and obtained by trawling in the canyons of the French Mediterranean.

Layer of points representing the abundance weighted per canyon of observed organisms during submersible dives in the Mediterranean continental canyons.

The data are provided as a layer of points representing the benthic samples (operations) in the French Mediterranean. The lists of species identified corresponding to these sampling points are given in the bibliographic references indicated in the layer.

Species distribution is provided as a layer of points representing in situ observations of organisms during submersible dives into the canyons of the Mediterranean mainland.

The objective of this cruise, which has been taking place in the English Channel - Baie de somme since 1980, over 5 days in September, is to evaluate the natural multi-year fluctuations of the stands and to analyze the possible impact of the nuclear power plant on the marine environment and resources. It makes it possible to determine annual indices of abundance and distribution of flatfish and other species (shrimp, pout, whiting).
