SSH and SST - Pacific Ocean

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

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

This visualization shows total sea level change between 1992 and 2019, based on data collected from the TOPEX/Poseidon, Jason-1, Jason-2, and Jason-3 satellites. Blue regions are where sea level ha...

SSH and SST - Indian Ocean

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...

SSH and SST - Global

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

TOPEX/Poseidon Launch

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.

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

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.

In many communities in the U.S., sea level rise is already a factor in people’s lives in the form of high-tide flooding.

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

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.

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.

Sea Surface Height 01/2006-04/2010

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

Sea Level Isn't Level - Why it matters

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

El Niño/La Niña - (12/1996 - 01/2000)

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...

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.

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 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
