The Pacific Ocean dominates this maritime survey off the coast of Ventura County, California. This sheet covers a specific open-water quadrant in the southern reaches of the Channel Islands region, serving as a navigation and bathymetry-focused reference for the waters surrounding the Anacapa Island chain. Published by the U.S. Geological Survey in the early 21st century, the map illustrates the vast marine environment and the geographical coordinates that define this offshore territory. Given the absence of terrestrial landmarks on this specific sheet, it remains an essential document for researchers tracking maritime boundaries and the oceanic context of the northern Channel Islands.
