SSH and SST - Indian Ocean

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...

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

Earth’s global sea levels are rising – and are doing so at an accelerating rate.

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.

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

The Argo stop-motion animation aims to inspire children (and adults) to engage with marine science. It is quirky, fun and informative at the same time. The animation explains what an Argo float is,...

For over 20 years NASA has been tracking the global surface topography of the ocean in order to understand the important role it plays in our daily lives. Climate change is causing our Ocean to war...

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.

A look at how NASA is dealing with the threat of sea level rise to its coastal infrastructure.

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

For NASA engineer Shannon Statham, building spacecraft is all about being creative.

NASA Climate Watcher Waves Goodbye

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

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.

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...

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

Watching Our Oceans

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

NASA and its U.S. and international partners have teamed up to launch a new Earth-observing satellite called Sentinel-6B that will measure sea surface height of most of the planet’s ocean. These ob...

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

El Niño/La Niña - (12/1996 - 01/2000)

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

TOPEX/Poseidon Launch

One of the best ways to understand Earth's ocean is from the perspective of space.
