Oceans' Role in Climate - Jason-1

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

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...

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

Mission team members perform acoustic tests of the Sentinel-6 Michael Freilich satellite in a chamber outfitted with giant speakers that blast the spacecraft with sound. This is to ensure that the ...
