Dive Into Your Sanctuaries

 

Our planet is an ocean planet: Earth Is Blue. The National Marine Sanctuary System protects some of the most iconic underwater places throughout the United States, but we can't do it without you. No matter where you are, the ocean and Great Lakes are in your hands. We hope these images inspire you to help care for our ocean and to spread the word that Earth isn't green – it's blue.
