attenuation coefficient (KPAR, m-1)

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.

Modelised abundance of species or prediction uncertainty.

Modelised adundance of several species eggs or prediction uncertainty.

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

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.
