Chumash Heritage National Marine Sanctuary

The Chumash Heritage National Marine Sanctuary is a federally protected marine area in the Pacific Ocean off the Central Coast of California, stretching across the coastlines of San Luis Obispo and Santa Barbara counties from south of the Diablo Canyon Power Plant to Naples Reef on the Gaviota Coast. Encompassing roughly 4,543 square miles of ocean water and coastline, it is the third-largest sanctuary in the U.S. National Marine Sanctuary system and the first such sanctuary ever proposed by an Indigenous group in the United States. Designated on October 11, 2024 by the National Oceanic and Atmospheric Administration (NOAA), the sanctuary protects nationally significant natural, cultural, and historical resources along one of the most ecologically rich and oceanographically dynamic stretches of the Pacific Coast. Its waters mark a major biogeographic transition zone where northern cold-water species meet warmer southern species, fueled by the California Current and seasonal upwellings. The ocean floor beneath the sanctuary includes submarine features such as Arguello Canyon, Rodriguez Seamount, and a portion of the Santa Lucia Bank. Beyond its ecological role, the sanctuary holds profound spiritual and historical meaning for the Chumash and Salinan peoples, whose coastal communities have inhabited this region for thousands of years. It also encompasses more than 200 documented shipwrecks that reflect centuries of maritime travel along the California coast, and it supports vibrant commercial and recreational fishing, tourism, and research activities that connect the region's living marine heritage with its deep human past.
