SSH and SST - Global

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 World: How High is the Ocean?

This video discusses the water cycle, which is the movement of water around the Earth, and its importance to life. Changes to the water cycle affect climate and vice versa.

Karl and Seymour learn how carbon dioxide is formed in this sketch from The Lollygaggers, a global warming sketch comedy.

Watching Our Oceans

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 ...

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

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

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

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

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

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.

OSTM/Jason-2 - All instruments plus data animation

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.

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

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

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