Pacific Ocean waters dominate this 2018 coastal survey, illustrating the maritime environment surrounding the offshore territory of Los Angeles County. The map focuses primarily on the open sea, providing precise bathymetric and navigational coordinates for the waters of the San Clemente Island Central OE S quadrangle. The only terrestrial presence is a small, steep section of land in the northeast corner of the sheet, where closely packed contour lines indicate a dramatic rise in elevation directly from the shoreline. This stark contrast between the expansive deep-water surface and the sudden topographic relief of the island's fringe offers a clear look at the geological profile of California's Channel Islands region in the early 21st century.
