SSH and SST - Global

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.

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

For NASA scientist Severine Fournier, studying our planet knows no borders.

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.

It's hard to "see" sea level rise by just looking at the ocean, but its effects are very real.

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.

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

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...

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

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...

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 ...

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

A key ocean observation satellite has been named after Earth scientist Michael Freilich

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.

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

Greenland and Antarctica are home to most of the world's glacial ice – including its only two ice sheets – making them areas of particular interest to scientists.

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...

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.

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...
