When you look at our planet from space, one thing is abundantly clear: Earth Is Blue. Our planet is an ocean planet, and whether you live near the coast or a thousand miles from it, the ocean is part of your life. From providing the food we eat to determining our weather, the ocean matters to each of us -- and the National Marine Sanctuary System protects this vital resource.
With that in mind, the photos and videos of Earth Is Blue bring these ocean treasures directly to smartphones and computers all over the world, where they can serve as a tangible reminder that 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.

This stern little floof is none other than a white tern chick! Also known as fairy terns, or manu-o-kū in Hawaiian, these small birds breed throughout Papahānaumokuākea Marine National Monument in the Northwestern Hawaiian Islands. They're one of the 22 species of seabirds that breed and nest in the monument! Unlike most other seabirds, adult white terns don't build a nest; instead, they find a suitable spot on a tree branch, rock ledge, or other surface and lay their egg there. (Photo: Koa Matsuoka)
