Our Blue Heritage
National marine sanctuaries and marine national monuments protect and document historic shipwrecks and aircraft. We work with indigenous people to preserve and maintain their cultures. And we help safeguard the marine creatures that live in our marine protected areas so that future generations will get to know them as well.
