Bathymetric contours of the continental margin offshore of Washington, Oregon, and California based on data available in the late 1980s.

Bathymetric contours (contour interval 100 m) of the continental margin offshore of Washington, Oregon, and California (cowbat) were compiled from various sources available in the late 1980s and used to construct 1:1,000,000-scale maps (Chase and others, 1992a, 1992b; Grim and others, 1992). The contours range from 200 to 5300 m depth.

华盛顿州、俄勒冈州与加利福尼亚州近海大陆边缘的水深等值线（bathymetric contours，等值线间距100米，数据集代号cowbat）于20世纪80年代末基于可获取的多源资料汇编而成，用于制作1:100万比例尺地图（Chase等，1992a、1992b；Grim等，1992）。该等值线覆盖的水深范围为200米至5300米。
