Scattered across America’s ocean and Great Lakes are treasured places known as national marine sanctuaries. Sanctuaries, like our national parks, protect amazing places, are home to awe-inspiring species, and tell the stories of our past. Protected by the National Oceanic and Atmospheric Administration and supported by the National Marine Sanctuary Foundation, together we partner with communities to educate, study, and conserve these spectacular places for future generations.
