Coastal Bathymetry

Bering, Chukchi and Beaufort Seas

Bathymetric contours were generated from soundings collected by National Ocean Service vessels from 1900 to 1971. The 1:250,000 maps are available for U.S. coastal waters. Bathymetric contours are in meters, with 10 meter intervals out to 200 m. Beyond 200 m, contours are at 50 m intervals to maximum depth. The Bathymetric map was developed to provide detailed contours of underwater features. The maps serve as a basic tool for performing scientific, engineering, marine geophysical, and marine environmental studies. The map is not intended to be used for navigation. The map is in ARC/INFO format with line and polygon topology. Both the vectors and polygons have attributes indicating ocean depth.
