Today is #NationalMarineSanctuaryDay! #OnThisDay in 1972, Congress enacted the Marine Protection, Research, and Sanctuaries Act. Today, our system of underwater parks spans over 620,000 square miles of our ocean and Great Lakes. We are proud to partner with MarineSanctuaryFdn and NOAAFisheries to bring elementary-aged students, military service members, and their families into national marine sanctuaries nationwide. Check out these photos from this past year of our outings at Florida Keys National Marine Sanctuary, Flower Garden Banks National Marine Sanctuary, Monterey Bay National Marine Sanctuary, and Mallows Bay-Potomac River National Marine Sanctuary. Looking for easy ways to learn about marine ecosystems from home? We have some of the best National Marine Sanctuary resources on our website.
