Observations of the hydrographic regime across the continental shelf and offshore to depths exceeding 2000 rn were made in Autumn 1971 to investigate the possible extension of the California Undercurrent off the coast of Washington. Closely spaced stations, positioned by depth, were made to the bottom on each crossing of the continental slope. Geostrophic calculations relative to 1000 m and extending up the slope to shallower depths indicated a broad band of northward flow above the continental slope....
