Who we are
The Foundation is a leading voice for U.S. protected waters, working with communities to conserve and expand those special places for a healthy ocean, coasts, and Great Lakes. Working together, we safeguard species and the places they call home, and preserve America’s maritime history.
National marine sanctuaries and monuments — our wondrous protected waters — teeming with life and inspiring a proud community of stewards for our ocean, coasts, and Great Lakes.
The National Marine Sanctuary Foundation supports projects across the National Marine Sanctuary System, a network of nationally significant protected areas in our ocean, coasts, and Great Lakes. The National Marine Sanctuary System is comprised of 14 individual sites and spans more than 600,000 square miles of American waters.
