The Channel Islands National Marine Sanctuary is an oceanic reserve area off the Channel Islands in the Pacific Ocean. It is responsible for the protection and preservation of submerged remains of the past that occupy the bottomlands of this 1,252-square-nautical-mile piece of the Pacific Ocean surrounding the Channel Islands National Park. The Sanctuary is located just off the coast of California's Central Coast, more specifically, Oxnard. The sanctuary's waters host a huge variety of plants and animals, and is home to an abundance of submerged Chumash Native American artifacts and the remains of more than 100 historic shipwrecks. For scuba divers, giant kelp forests, pinnacles, and ledges beneath the surface of the Pacific lay waiting to be discovered.
