Between 1977 and 2006, in September, IFREMER conducted French Young Fish Surveys alond the French coasts. This dataset comprises data from four surveys covering different periods (Bay of Veys, 1977-1981; Bay of Seine, 1995-2002; Bay of Somme, 1998-2006; DYFS, 1977-1983). The French YFs taking place in the Bays of Somme and Seine uses a 3 m beam trawl outside of the bays, but a 2 m beam trawl witin the bays. Data have sometimes been standardised to take into account the difference in gear characteristics.
- Description
-
Kriging produces an estimation of the interpolation error (measured as an estimation variance), whereas classical interpolation methods, based on arbitrary mathematical functions, cannot estimate it. Moreover, this error is reduced as much as possible as the kriging predictor minimises it by definition. Indeed, for each estimation, the weights given to neighbouring observations are computed from the variogram model and are derived so as to minimise the estimation variance. As a result, for mapping purposes, kriged interpolation produces a large field of estimates at points or blocks and corresponding kriging error.The kriging error grids of points resulting from the interpolation of biological parameters 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 interpolation error of each parameter.
