On October 23rd, 2022 the National Marine Sanctuary System celebrated it’s 50th anniversary. While we reflect on the past 50 years, it’s important we point to the future and emphasize the importance of protecting the sanctuaries for another five decades and beyond. Join us in celebrating this momentous milestone as we look to the future of many more years of ocean stewardship.

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.
