Gridded Depths for the North Pacific 
Location: Northern Pacific Ocean 
Description of Data: This is a digital bathymetric data base for the north 
Pacific Ocean compiled by the US Naval Ocean Research and Development 
Activities. The data consist of minimum, maximum, and average depths for 
30- by 30-nautical-mile-square areas. The file comprises 29,250 records. 
The coordinates of position are keyed to the southwest corner of the 
30-nautical-mile-square grid in which the data are located. "The Bathymetric 
Atlas of the North Pacific," Naval Oceanographic Office Publication 1301-2-3 
(1971) constitutes the data base from which the gridded file was derived. 
Survey control, which is highly variable, may be determined by reference to 
the atlas.
