A marine national monument is an ocean area designated by a presidential proclamation under the Antiquities Act. The U.S. Fish and Wildlife Service partners with the National Oceanic and Atmospheric Administration (NOAA), state and territorial governments and others to manage marine national monuments that conserve the ocean and remote islands and atolls within the National Wildlife Refuge System. NOAA and the U.S. Fish and Wildlife Service cooperatively manage four marine national monuments in the Pacific Ocean and one in the Atlantic.
