Bathymetric contours of the continental margin offshore of Washington, Oregon, and California based on data available in the late 1980s. bathymetry 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. Muriel Grim
Reprocessed legacy seismic-reflection data from USGS field activity B-1-72-SC collected offshore central California uniboom Seismic-reflection data were collected offshore central California in 1972 aboard the USNS Bartlett (USGS Field Activity B-1-72-SC). In 2021 these legacy data were reprocessed to improve accuracy and geologic resolvability of California's continental margin. Daniel J Kennedy
