From the western Pacific waters of American Samoa, east to the Atlantic Ocean, NOAA's Office of National Marine Sanctuaries manages a national network of special places, encompassing more than 600,000 square miles of U.S. ocean and Great Lakes waters. The Office of National Marine Sanctuaries publishes a national newsletter in electronic format and distributed via email to keep our colleagues, collaborators and you! informed about the many activities and accomplishments that take place within our 13 national marine sanctuaries and Papahānaumokuākea and Rose Atoll marine national monuments.
