Global sea level rise is accelerating incrementally over time rather than increasing at a steady rate, as previously thought, according to a new study based on 25 years of NASA and European satelli...

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.

Launching aboard the joint U.S.-European Sentinel-6 Michael Freilich satellite is NASA’s next instrument that will help improve weather forecasting.

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...

SSH and SST - Pacific Ocean

NASA Climate Watcher Waves Goodbye

Here we provide side by side comparisons of Pacific Ocean sea surface height (SSH) anomalies of what is presently happening in 2015 with the Pacific Ocean signal during the famous 1997 El Niño.

It’s not only water processes that play a role in global sea level rise – ground movements can play a significant role as well.
