The Blue and You

The National Marine Sanctuary System protects more than 620,000 square miles of ocean and Great Lakes waters—but none of it could be protected without you. Volunteers, visitors, students, and local communities are the backbone of the sanctuary system. You restore fragile ecosystems, remove marine debris from impacted habitats, conduct science, and speak up on behalf of your national marine sanctuaries and marine national monuments. The Blue and You are indelibly linked, and it’s thanks to you that the sanctuary system continues to thrive.
