This dataset originated from three source layers (3km * 3km resolution) computed within the work package 3 of EU ATLAS project, and based on the EMODnet Digital Bathymetry portal and the General Bathymetric Chart of the Oceans (GEBCO). From these source layers, the mean depth (m), slope (degree) and BPI (no unit) were calculated for each 25km * 25km gridsquare. This dataset was built to feed a basin-wide spatial conservation planning exercise, targeting the deep sea of the North Atlantic. The goal of this approach was to identify conservation priority areas for Vulnerable Marine Ecosystems (VMEs) and deep fish species, based on the distribution of species and habitats, human activities and current spatial management.

The original resolution from EMODnet (0.002°) was up-scaled to the GEBCO resolution (0.008°) using a bilinear interpolation. The bathymetry layers were merged by using EMODnet data when available and completing it with GEBCO 2014, and rescaled to the final resolution of 3x3 km using bilinear interpolation. Slope (in degrees) was derived from the final bathymetry grid using the package raster of the R environment and the Bathymetric Position Index (BPI) was computed using the Benthic Terrain Model 3.0 tool in ArcGIS 10.1 with an inner radius of 3 and an outer radius of 25. In order to avoid extreme values, BPI was standardized using the scale function from the raster package. References: EMODnet Bathymetry Consortium. (2016).

Mean values of depth, slope and BPI were calculated for each gridsquare using the extract function from the velox package in R, allowing to account for the area of each raster cell overlapping with the gridsquare. Polygon gridsquare were transformed back to raster using the rasterize function from the velox package. extraction of variables on the ATLAS grid
