Louis Cabioch, Franck Gentil, René Glaçon and Christian Retière sampled between 1971 and 1976, 1495 stations between longitude 2° W and the French-Belgium border : sampling strategy is regular in homogeneous areas and is intensified in coastal areas and on the Flanders sand banks / qualitative samples taken using a “Rallier du Baty” dredge (45 cm in diameter) /for each standardised sample (30 L of sediments), detailed observation of the visible fauna then the collected fraction after sieving (2mm mesh) was studied in the laboratory. Total species richness and total abundance were calculated for each station. Abundances of 19 species were sorted in order to be presented in this work (ABRAALB, AEQUOPE, AMPESPI, ASTERUB, BRANLAN, BUCCUND, EBALSPP, ECHICOR, ECHIPUS, GALAINT, GASTSPI, GLYCGLY, OPHEBOR, OPHIFRA, OPHISPP, PISILON, PSAMMIL, THIASCU, UPOGDEL). Plus total species richness and total abundance

Statistical analysis : the statistical distribution of biological data were tested for normality (histograms, skewness, kurtosis). The data were transformed whem skewness value exceeded |1| and/or kurtosis exceeded 1 and if a normalising function that could improve the data distribution was found. Variables were measured on scales based on analytical conventions that are unrelated to the natural processes generated them. Therefore, any transformed scale is as appropriate as those on which these data were originally recorded. 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 longitudes). The grid of points was imported into ArcMap and interpolated with the Spatial Analyst extension in order to create a continuous raster of 1 km² resolution. The resulting maps illustrate the spatial distributions and the variations over time for data studied in CHARM's area. For legends of maps, approximates od the 5th and the 95th quantiles were used for the minimales and maximales values respectively.
