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.
-
Biological data have been expressed in abundance (number of individuals per 20 m3).
-
Three environmental parameters were measured in situ during the REISE2 survey in April 1995. Temperature and salinity were measured using a probe. Fluorescence (mean for the water column) was measured using a fluorometer. This survey gives illustration of spring conditions.
-
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.
-
mineral Suspended Particulate Matter (g.m-3)
-
Sea Surface Temperature (SST, in °C)
-
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.
-
attenuation coefficient (KPAR, m-1)
-
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
-
Localisation of the 39 sampled sites done during the BCD survey in April 1999.
