Abundances were recoded in term of presence-absence. Geostatistical interpolation : the spatial variation of biological data were analysed using GENSTAT (GENSTAT 7 Committee, 2004), which is a GENeral STATistics package including the main geostatistical tools. It computes experimentala variograms, fits these with various authorised mathematical models and uses them to calculate kriged estimates on a fine regular grid (of latitudes and…

Landings in tonnes of live fish per quarter: mean over 7 years (2000-2006), France and United Kingdom

Modelised abundance of species 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.

Spatial distribution of benthic communities of the eastern English Channel, based on historical surveys (PhD of L.E. Sanvicente-Anorve, 1995).

Abundance of several species in coastal nurseries along french coasts. Kriging error (v) resulting from the interpolation of these data was maped.

Biological data have been expressed in abundance (number of individuals per 20 m3).

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.

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).

Species habitat occupation, observed during the third quarter IBTS from 1991 to 2010, has been expressed as rare, occasional, frequent, recurrent depending on density levels and variability over time.
