Watching Our Oceans

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

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...

Sea levels across the globe are rising as a result of a changing climate — and the rate at which they are rising is accelerating. NASA Science Live was recorded Tuesday, Nov. 17, 2020, and featured...

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.

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

Sea Surface Height - Global Average from 1993 - 2011.

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...

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

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.

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

A SpaceX Falcon 9 rocket lifts off from Space Launch Complex 4 at Vandenberg Air Force Base carrying the Jason-3 spacecraft. Liftoff was at 10:42 a.m. PST (1:42 p.m. EST).

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...

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...

Our World: How High is the Ocean?

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

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