Seasonal spatial distribution of gray seals (Halichoerus grypus) on their haul out sites identified by the associations ADN and Picardy Nature in the Authie Bay from 2007 to 2009 inclusive.

Location distribution per grid cell of 8 harbor seals (Phoca vitulina), followed by Fastloc GPS / GSM tags from the bay of Mont Saint-Michel from 2006 to 2008

Eutrophication status of the OSPAR of 2007 zones of metropolitan France. Data collected in the course of "initial assessment" phase of the MSFD.

Spatial distribution of quarterly harbor seals (Phoca vitulina) identified by Aérobaie and the Réserve Naturelle du Domaine de Beauguillot (Nature Reserve of Beauguillot) on their haul out sites in the Bay of Somme from 2007 to 2009 inclusive.

The statistical analysis used (Principal Component Analysis followed by a classification method) to identify groups common to all months and describe the evolution of these groups during the year. The data used allows for monthly tables showing the selected parameters, calculated over the entire geographic area with a resolution of 0.1 °. This method identifies 10 hydrological landscapes present at various times of the year, and characterized by homogeneous hydrological conditions.

3D seasonal temperature range (in ° C) obtained by objective analysis (interpolation) of the raw data in situ, near the seafloor. Within the Bay of Biscay Challenge and the programme of the Operational Coastal Oceanographic Centre Prévimer, the services of SISMER DYNECO-PHYSED of IFREMER have built a joint hydrological database of the Bay of Biscay, from CTD measurements, Bouteilles, XBT / MBT and Profileurs from multiple global data centres to achieve a climatological atlas of the region for temperature and salinity.

Zones corresponding to the delimitation of major watersheds and related marine areas in the Seine-Normandy basin for the assessment of pressures on the different water masses on the Normandy coast and marine sub region English Channel - North Sea. Nutrient discharges from industries and communities.
