Bathimetry and morphostructure of the Barents-Kara Seas shelf

Abstract

A new version of bathymetric map of the Barents and Kara Seas 'shelf is compiled on the base of newly obtained sparker records, seismic acoustic data, echosoundings and revision of previous maps and schemes. Barents and Kara Seas shelf is mutual continental margin of Norwegian-Greenland and Eurasian basins of Arctic Ocean. These oceanic basins are the youngest ones on the Earth; that is the reason of unique geostructural position of Barents and Kara Seas shelf. Bathymetry of this region corresponds to its morphostructure. Extremely dissected relief is interpreted as the evidence for recent tectonic activity of the continental margin of transitional (from passive to active) type, passing the earlier stage -of its evolution.
