Data_collect The BCD survey (¿Biodiversity and cartography throughout the Dover Straits) was held at the end of April 1999, with sampling from 39 stations. The BCD survey was financed by the European INTERREG II programme (1995-2001) and produced maps of larvae stages and plankton. The aims of the BCD survey was to compare planktonic assemblages on the French and English coasts. Ichthyoplankton was collected with a double-framed bongo net (plankton nets with 500 m mesh). Oblique tows were carried out at 2 knots from the surface to the proximity of the seabed

Data_assment Statistical analysis : the statistical distribution of environmental 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. Environmental 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 environmental 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 environmental 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
