Bathymetric grid (1000 m) of the continental margin offshore of Washington, Oregon, and California based on data available in the late 1980s.

Cowbatg.tif is a 1000-m resolution bathymetric grid of the continental margin offshore of Washington, California, and Oregon. The grid was generated from bathymetric contours (cowbathy.shp, also in this data set) mapped by Chase and others (1992a, b) and by Grim and others (1992) from various sources of bottom topography of the continental margin off the states of Washington, Oregon, and California.

Cowbatg.tif 是一套分辨率为1000米的水深栅格数据，覆盖华盛顿州、加利福尼亚州及俄勒冈州近海的大陆边缘。该栅格数据由Chase等人（1992a、1992b）与Grim等人（1992）基于华盛顿、俄勒冈、加利福尼亚三州近海大陆边缘的多源海底地形资料绘制的水深等值线（cowbathy.shp，亦包含于本数据集）生成。
