A U.S. National Marine Sanctuary is a zone within United States waters where the marine environment enjoys special protection. The program began in 1972 in response to public concern about the plight of marine ecosystems.
A U.S. National Marine Sanctuary is a federally designated area within United States waters that protects areas of the marine environment with special conservation, recreational, ecological, historical, cultural, archeological, scientific, educational, or aesthetic qualities. While National Marine Sanctuaries are multiple-use areas, the NMSA emphasizes that one of the express purposes of a sanctuary is to “maintain the natural biological communities” and to “protect and, where appropriate, restore and enhance natural habitats, populations, and ecological processes.” The National Marine Sanctuary System consists of 15 marine protected areas that encompass more than 783,000 square miles (2,030,000 km2). Individual areas range from less than 1 to 583,000 square miles (3 to 1,509,963 km2).
