NASA's cutting-edge research, unique facilities and diverse workforce provide an ideal backdrop for these experiences. Find out more about these programs. Because the oceans are so expansive, covering two-thirds of Earth, the only way to study them on a broad scale is by observing them from space. NASA and its partners use this unique vantage point to measure ocean height, winds, and temperature. Come learn about these ocean features, how ocean circulation works, and the important role it plays in our lives.
Oceans are actually many shades of blue, green and even red.
This spectrum of color tells us a lot about the health of our oceans, which affects life on Earth. NASA's ocean-color observations from space give us the big picture of oceans and help to understand the role oceans play in global change. Discover the excitement and importance of viewing from high above Earth this ever-changing portrait of ocean productivity, ecosystems, and human impacts. Download the RealPlayer .
