Our Blue Planet

Our Lives Depend on the Ocean. NOAA Is Working to Protect It.


The ocean covers more than 70 percent of Earth’s surface. It produces every other breath we take and has absorbed over 25 percent of our carbon dioxide emissions since 1800. Our lives depend on the ocean. Yet, about 95 percent remains unexplored. And less than five percent of the ocean is protected.

Fortunately, NOAA is working to expand our ocean knowledge and protect marine life. What wonders have we yet to discover? How can we live sustainably on our Blue Planet? Dive into the Ocean Today website to join our exploration!
