The goal of the International Bathymetric Chart of the Arctic Ocean (IBCAO) 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.
Version 5.2 of the IBCAO data set is now available to download and is included, as a regional compilation, in the global GEBCO grid.
Two versions of the grid are made available, one with and one without elevation information for the Greenland ice sheet. The data are made available in Polar Stereographic projection co-ordinates (meters).
