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

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...

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...

Oceans of Climate Change

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...

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

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...

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

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

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

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

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.

NASA Climate Watcher Waves Goodbye

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...

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

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

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.

The ocean is responsible for Earth's mild climate and makes life on Earth possible for all creatures.

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.

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