International Bathymetric Chart of the Arctic Ocean (IBCAO) |
Land elevations were derived by re-sampling the GTOPO30 1-km grid issued by the US Geological Survey; oceanic depth were produced by combining all available original public-domain bathymetric observations, supplemented by information extracted in contour form from published maps and charts.
The grid was constructed in October 1999 by
Martin Jakobsson of Stockholm
University, in collaboration with Norman Z. Cherkis of Five Oceans Consultants and with the
assistance of John Woodward of the Royal Danish Administration of Navigation and Hydrography,
Jennifer Harding of the Geological Survey of Canada, and the editorial board for IBCAO.

The grid was converted to vector data with ArcInfo® using Delauny Triangulation in 100 m depth intervals. Vector data in ASCII-format were converted to the layer-format of PanMap. This is a provisional version of the IBCAO which will be continuously improved by new data.
Data are organized in files per elevation line. Extraction of the *.zip-files will result in *.lay-files, which have the proprietary format used by PanMap. The first two files contain ALL LINES in one zip-archive in 10 % and full resolution. In the list below also each SINGLE LINE is accessible for individual selection. Data are also available in shape-file format to be used with ArcView® (120 MB).
