Watching Our Oceans

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...

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...

It's hard to "see" sea level rise by just looking at the ocean, but its effects are very real.

The ocean-observing Sentinel-6 Michael Freilich satellite launched from Vandenberg Air Force Base in California aboard a SpaceX Falcon 9 rocket on Nov. 21, 2020 at 12:17 p.m. EST

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

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.

TOPEX/Poseidon Ground Tracks

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.

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

Earth’s global sea levels are rising – and are doing so at an accelerating rate.

Experts from NASA, ESA, EUMETSAT, and NOAA discuss the upcoming launch of Sentinel-6 Michael Freilich in a recorded live broadcast

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.

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

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

Sea Level Isn't Level - Why it matters

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...

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...
