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

Elevation

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). 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.

Data origin:

The three terrain variables were initially computed for the ATLAS Deliverable 3.3 by IMAR (Instituto do Mar, Universidade dos Açores, Horta, Portugal). The values of initial layers of 3km * 3km resolution were averaged in 25km * 25 km gridsquares of the raster grid used for the ATLAS spatial prioritization.
