In 1972, in response to a growing awareness of the value of our coastal waters, Congress passed the Marine Protection, Research, and Sanctuaries Act. The act authorized the designation of National Marine Sanctuaries to protect significant waters and secure habitat for aquatic species, shelter historically significant shipwrecks and other cultural resources, and serve as valuable spots for research, fishing, wildlife viewing, boating, and tourism.
