IBCAO Arctic Bathymetry
The International Bathymetric Chart of the Arctic Ocean (IBCAO) is a digital data base that contains all available bathymetric data north of 64 degrees North. This project, which began in 1997, is a cooperative effort between researchers at eleven different institutions in eight countries. The countries involved are Canada, Denmark, Germany, Iceland, Norway, Russia, Sweden, and the USA. Five of the key organizations involved were the International Arctic Science Committee (IASC), the International Hydrographic Organization (IHO) the Intergovernmental Oceanographic Commission (IOC), the US National Geophysical Data Center (NGDC/NOAA), and the US Office of Naval Research (ONR).
A beta version of the IBCAO grid was released in 2000 and was included on the RiverTools 3.0 sample data CD. The official release of version 1 was in 2001, followed by the releases of versions 2 and 3 in 2008 and 2012. Information for all versions is given in the table below. Note that geographic (unprojected, fixed-angle) versions are also available and may be better for some applications.
