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.

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.

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 abundances of several species in coastal nurseries or prediction uncertainty.

Modelised adundance of several species eggs or prediction uncertainty.

Modelised abundance of species or prediction uncertainty.

Abundance of several species in coastal nurseries along french coasts.

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.

Fish larvae were collected during the night using a MIK (Methot Isaac Kidd) net (2m diameter, 500 um mesh). Abundances were expressed in term of number of individuals per 5000 cubic meter (ind.5000m-3). For clupeidae (herring and pilchard), gobiidae and ammodytidae, abundances were log-transformed (log10(x+1)) prior to analysis whereas for pleuronectidae and syngnathidae, abundances were recoded in term of presence-absence.
