When astronauts first launched toward the moon and looked back at our planet for the first time, they made an unexpected discovery: Earth is Blue. We will be sharing a photo each day and a video each week highlighting the wonder and beauty of these special places and the work we do to protect them.
Join us as we explore America's national marine sanctuaries and share your own images of our national marine sanctuaries using the hashtag #EarthIsBlue.
The Office of National Marine Sanctuaries serves as the trustee for a network of 14 marine protected areas encompassing more than 170,000 square miles of marine and Great Lakes waters from Washington state to the Florida Keys, and from Lake Huron to American Samoa. The network includes a system of 13 national marine sanctuaries and the Papahānaumokuākea Marine National Monument.
