Watching Our Oceans

This animation illustrates the evolution of sea surface temperature (SST) anomalies (relative to the respective normal state) in the Pacific Ocean associated with the 2015-2016 El Niño.

Sea levels across the globe are rising as a result of a changing climate — and the rate at which they are rising is accelerating. NASA Science Live was recorded Tuesday, Nov. 17, 2020, and featured...

Ice covers 10 percent of Earth's surface and helps moderate the planet's temperature.

Watch the Jason-3 Mission Briefing from Friday, Jan 15, 2016 - panelists gave an overview of the Jason-3 mission.

Changing conditions in the Pacific have stirred up Earth’s largest ocean and redistributed its heat, piling up warm waters along U.S. Western shores and raising sea level in the process.

Sea Level Isn't Level - Why it matters

The Jason-2 satellite sees something brewing in the Pacific. Researchers say it could be a significant El Niño with implications for global weather and climate.

To provide scientists with essential information about global and regional changes in the seas, NASA will launch the Jason-3 satellite from Vandenberg Air Force Base in California.

Earth’s rising seas are some of the most visible signs of our warming planet. Over the last 23 years, NASA satellite missions have observed a steady rise in global sea levels as polar ice sheets me...

The ocean-observing Sentinel-6 Michael Freilich satellite launched from Vandenberg Air Force Base in California aboard a SpaceX Falcon 9 rocket on Nov. 21, 2020 at 12:17 p.m. EST

On Aug. 26, 2015 at 9:30 a.m. PT, NASA hosted a media teleconference to discuss recent insights on sea level rise and the continuing challenge of predicting how fast and how much sea level will ris...

TOPEX/Poseidon Ground Tracks

This video discusses the water cycle, which is the movement of water around the Earth, and its importance to life. Changes to the water cycle affect climate and vice versa.

On the left is Sea Surface Height Anomalies (SSHA) relative to the sea level mean (1993-2018). On the right is Global Mean Sea Level (GMSL) with the sea level trend as the straight line. The data a...

Our World: How High is the Ocean?

Fathoming the forces that determine global sea levels can be daunting. We present a guide to the basics of ocean surface topography.

Sentinel-6 Michael Freilich will join a long-standing family of Earth observing satellites from NASA and European partners.
