- Statement
- 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
- For each parameter (surface and bottom temperature, surface and bottom salinity), the average (mean) and the standard deviation (sd) are computed from kriged annual maps over all the available period. The sum of all annual kriging error over the same period (v) is also computed. The resulting grids of points were 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 average pattern (mean), its interannual variability (sd) and its overall interpolation error (summed kriging error) of each parameter.
