The coastal waters of the Pacific Ocean dominate this 2012 maritime study, which captures the shoreline as it appeared in the early 21st century. The map is primarily an offshore record, focusing on the depths and coordinates of the sea west of the California coast. On the small sliver of land visible in the southeast corner, Purisima Point extends into the surf, providing a rare terrestrial anchor for this largely oceanic sheet. This specific projection by the U.S. Geological Survey is essential for researchers or collectors tracing the exact bathymetric and coastal boundaries of Santa Barbara County in this era.
