Animation: Reshaping Earth - How the TOPEX and Jason Satellites Revolutionized Oceanography and Redefined Climate Science
January 28, 2021
Humans are reshaping the Earth. Not just the climate of Earth, but the planet itself. As the Earth warms due to human interference with the climate, the oceans rise. And covering more than two thirds of the planet’s surface it means the rising oceans are literally changing the shape of the planet we call home. And since the early 1990s, a single series satellites has captured this change with unbelievable accuracy. Built to measure changes in ocean currents, our sea level satellites have revolutionized our understanding of the oceans and now provide one of the most important records of how fast our climate is changing.

This animation depicts gridded, daily volumetric water content estimated for the 0-5 cm surface soil layer between March 2017 and August 2020. These soil moisture data constitute the first land product from CYGNSS, a NASA Earth Ventures mission and satellite constellation for ocean surface remote sensing using a technique called GNSS-Reflectometry, and represent a starting point to explore land surface research applications using this promising new technique. The dataset can be accesses from the PO.DAAC Portal at https://doi.org/10.5067/CYGNU-L3SM1 (DOI: 10.5067/CYGNU-L3SM1)
Animation: “Science is International” Says French Sea Level Rise NASA Scientist | Sentinel-6 Michael Freilich
October 29, 2020
For NASA scientist Severine Fournier, studying our planet knows no borders. Our changing ocean affects everyone across the globe. That’s why the new Sentinel-6 Michael Freilich satellite, launching Nov. 10, is a truly international mission that will study our rising seas from space.
October 29, 2020
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 how climate change is reshaping our planet.

Studying sea level rise today will help us better understand its impact on tomorrow. 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 launch of the Sentinel-6 Michael Freilich satellite will provide new and better insights about our Earth’s changing ocean.
Animation: NASA Engineer Helps Track the Global Impacts of Rising Seas | Sentinel-6 Michael Freilich
October 29, 2020
Earth’s surface is covered by 70% ocean. Rising seas caused by climate change affect everyone across the globe, from coastal communities to those living inland. 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 track our rising seas.
