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

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.

Temperature and salinity were measured, in situ at sea surface and at bottom during the IBTS surveys from 1980 to 2010 . Temperature and salinity were measured using CTD probe. The IBTS survey, which takes place each year in January, gives a good illustration of winter conditions.

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

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. Abundance mean (mean) and standard deviation (st) have been calculated. The sum of the kriging error for each yearly kriged abundance fits to the kriging error (v).

Three environmental parameters were measured in situ during the IBTS in 2007. Temperature and salinity were measured using thermosalinometer 3 to 5 m under sea surface. Sub-surface (3-5 m) chlorophyll a concentration was measured using a fluorometer (measure the fluorescence emitted by the pigment). The IBTS survey, which takes place each year in January, gives a good illustration of winter conditions.

Temperature and salinity were measured in situ at sea surface and at bottom during the CGFS surveys from 1997 to 2006. Temperature and salinity were measured using a probe. These surveys give illustration of autumn conditions. Average, standard deviation and interpolation error of yearly maps were produced
