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

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.

Location distribution per grid cell of 8 young harbor seals (Phoca vitulina), followed by Argos tags (between 2005 and 2008) along the English Channel coast following rehabilitation at the care center CHENE.

This product contains data in a grid form with all the digital files of the SHOM relating to tides of the Metropolitan French coast in the English Channel and the Atlantic coast. These digital files indicate the components of the tidal surface, hour by hour and for two tidal coefficient characteristics (45 and 95). The current points contained in the files correspond to the arrows shown in the currents atlas.
