Pacific Ocean waters dominate this marine survey, which focuses on the offshore boundaries of Southern California during the mid-2010s. The map illustrates the maritime limits of Ventura Co and the state of California as they intersect with the protected marine environment. A portion of the Channel Islands National Park is demarcated in the upper northwest corner, representing a significant federal conservation area established to protect the unique biodiversity and archaeological sites of the archipelago. This sheet is primarily a hydrographic and jurisdictional reference, showing the spatial relationship between the mainland's administrative reaches and the open sea.
