Watching Our Oceans

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

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

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

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

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.

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).

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.

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

Sea Surface Height 01/2006-04/2010

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

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...

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...

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...

A look at how NASA is dealing with the threat of sea level rise to its coastal infrastructure.

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...

Watch the Jason-3 Mission Briefing from Friday, Jan 15, 2016 - panelists gave an overview of the Jason-3 mission.

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.

OSTM/Jason-2 - Data/ground track animation

Ice covers 10 percent of Earth's surface and helps moderate the planet's temperature.

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.

Sentinel-6 Michael Freilich will join a long-standing family of Earth observing satellites from NASA and European partners.

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.
