Deep-sea bathymetric variables (slope, depth, BPI) on the North Atlantic

Distribution of three bathymetric terrain variables (depth, slope and Bathymetric Position Index) on the North Atlantic (18°N to 76°N and 36°E to 98°W). The three source layers (3km * 3km resolution) were computed within the work package 3 of EU ATLAS project, and derivated from the EMODnet Digital Bathymetry portal and the General Bathymetric Chart of the Oceans (GEBCO). 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.
