This layer is a georeferenced raster image (GeoTIFF) of a digital bathymetric model (DBM) of the Arctic Ocean compiled with all multibeam, dense single beam, and land data added at a resolution of 30 x 30 arc seconds. This is a reprojected version (WGS84) of the 500 meter resolution data layer. The original (DBM) was compiled with all multibeam, dense single beam and land data added at 500 x 500 m resolution in a final step using the remove-restore method. Data were compiled from several multibeam cruises in the region dating from 1994 to 2011. The goal of this initiative is to develop a digital data base that contains all available bathymetric data north of 64° North, for use by mapmakers, researchers, institutions, and others whose work requires a detailed and accurate knowledge of the depth and the shape of the Arctic seabed.
