Summary

The International Bathymetric Chart of the Arctic Ocean (IBCAO) Version 4.0 is a gridded continuous terrain model covering ocean and land of the Arctic region. The grid has been compiled from data covering approximately 14.2 percent of the Arctic seafloor with multibeam bathymetry and about 5.5 percent with other sources, excluding digitized depth contours. The grid-cell size (resolution) is 200x200 m on a Polar Stereographic projection, with the true scale set at a latitude of 75 deg N and a central meridian of 0 deg. The horizontal datum is WGS 84 and the vertical datum is assumed Mean Sea Level. IBCAO Version 4.0 has been compiled with support from the Nippon Foundation-GEBCO-Seabed 2030 Project, an international effort whose goal it is to see the entire world ocean mapped by 2030. A geographic version of the Polar Stereographic grid serves as input to the General Bathymetric Chart of Oceans (GEBCO) global gridded terrain model.
