Polygons which delimited the geographical studied area of the CHARM I project and the CHARM II project. Polygons which delimited the geographical suggested area of the CHARM III project.

Biologic data have been expressed in abundance (numbers or density values (nbr/km²)) and always required to be log-transformed using a log10(x+1) transformation.

Modelised abundance of species or prediction uncertainty.

Modelised abundances of several species in coastal nurseries or prediction uncertainty.

Localisation of the 39 sampled sites done during the BCD survey in April 1999.

Sea Surface Temperature (SST, in °C)

Depth is here bathymetry plus mean sea level. It adds the bathymetry raster to that of mean sea level. Depth is more relevant than bathymetry alone for ecological point of view. Used as layer for habitat

The English Channel is a biogeographical transition zone, situated between warm temperate and boreal marine province. This status enables the early detection of trends in the oceanic climate regime between two provinces. Mean SST maps for February (coldest month of the year) and August (warmest month of the year), from 1986 to 2006, were produced.

mineral Suspended Particulate Matter (g.m-3)

Modelised adundance of several species eggs or prediction uncertainty.
