TOPEX/Poseidon Ground Tracks

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

SSH and SST - Global

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...

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...

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

B-roll for media. The Sentinel-6 Michael Freilich is an Earth-observing satellite that will collect data on sea level and how it changes over time. By measuring sea surface height, scientists world...

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

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

Jason-3 3D Model

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

After living in coastal Virginia and seeing the effects of climate change firsthand, Ben Hamlington is now researching sea level rise at NASA JPL.

The Sentinel-6 Michael Freilich satellite sits in front of a testing chamber where mission team members tested whether the spacecraft could endure the loud sounds it will encounter during launch.

Jason-3 Satellite Prepared For Launch

On Aug. 26, 2015 at 9:30 a.m. PT, NASA hosted a media teleconference to discuss recent insights on sea level rise and the continuing challenge of predicting how fast and how much sea level will ris...

TOPEX/Poseidon over Earth

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.
