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.

"ROAR!! Just kidding, I'm a whale." Although humpback whales are large, they only feed on krill and small fish. Photographer Douglas Croft snapped this photo of a humpback whale taking a big gulp of anchovies! Humpback whales and other whales flock to the nutrient-rich waters of Monterey Bay National Marine Sanctuary to feed. By winter, most humpback whales leave the sanctuary for warmer waters in Mexico, but some juveniles and non-breeding adults stick around a little longer to take advantage of the over-whale-mingly large feast.
