Species and habitats - Limanda limanda - Immature - Mean abundance, standard deviation, and summed kriging error maps during BTS (1989 - 2010)
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).

The standard survey has a total of approximately 100 tows or stations (75 are in ICES division VIId,25 are in ICES division Ivc). A commercial 4m beam trawl fitted with a chain mat, flip-up ropes, and a 40 mm cod-end liner is used.The gear is towed at 4 knots (ground speed) for 30 minutes on a warp length appropriate to the depth of water. At each sampling station (only daylight), all the fish species are sorted, weighed, counted and measured.

Process step
- Description
-
For each species, 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.
