OSTM/Jason-2 - Data/ground track animation

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.

The joint U.S.-European Sentinel-6 Michael Freilich is the next in a line of Earth-observing satellites that will collect the most accurate data yet on sea level and how it changes over time. With ...

NASA and its partners announced the renaming of the mission, previously known as Sentinel-6A/Jason-CS.

NASA Climate Watcher Waves Goodbye

Our planet is changing. Our ocean is rising. And it affects us all. That’s why a new international satellite will continue the decades-long watch over our global ocean and help us better understand...

Jason-CS/Sentinel-6 - How they will work

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...

Watch the Jason-3 Science Briefing from Friday, Jan 15, 2016 - panelists discussed the science and research of the Jason-3 mission.

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.

Growing up in landlocked Zimbabwe, NASA JPL engineer Shailen Desai was far from the ocean but still experienced its effects on the climate. Now, he is contributing to an international effort to tra...

Jason-3 Animation

El Niño is characterized by unusually warm ocean temperatures in the eastern equatorial Pacific. The warmer water associated with El Niño displaces colder water in the upper layer of the ocean caus...

Decades of Discovery - How altimeters help us every day.

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...

Oceans of Climate Change

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...

Sea Surface Height - Global Average from 1993 - 2011.

The Jason-3 satellite, launched on January 17, 2016, is allowing scientists to continue a 23-year record of crucial ocean monitoring.

For NASA JPL engineer Parag Vaze, studying Earth’s rising ocean has been a career three decades in the making.
