SSH and SST - Pacific 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...

TOPEX/Poseidon Launch

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

Sea Level Isn't Level - Why it matters

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.

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

Experts from NASA, ESA, EUMETSAT, and NOAA discuss the upcoming launch of Sentinel-6 Michael Freilich in a recorded live broadcast

NASA Climate Watcher Waves Goodbye

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

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...

OSTM/Jason-2 - All instruments plus data animation

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...

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

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.

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

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

Our World: How High is the Ocean?

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

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.
