Physical environment - In situ data - Annual bottom temperature in October (CGFS) from 1997 to 2006

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.

Généralités sur la provenance
The survey extends from the Eastern English Channel to the south of the North Sea, which corresponds to ICES divisions VIId and IVc. The study area is divided into rectangles of 15’ latitude and 15’ longitude using a systematic sampling strategy. The sampling gear is a high opening bottom trawl well adapted for catching demersal species. Since 1997, temperature and salinity (surface and bottom) are measured using a probe attached on the headrope of the trawl.
Description
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.
