Recorded live launch broadcast of Sentinel-6 Michael Freilich

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

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...

It’s not only water processes that play a role in global sea level rise – ground movements can play a significant role as well.

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...

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

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.

Oceans of Climate Change

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.

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

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.

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

For over 20 years NASA has been tracking the global surface topography of the ocean in order to understand the important role it plays in our daily lives. Climate change is causing our Ocean to war...

Sea level rise is an indicator that our planet is warming. When ice on land, such as mountain glaciers or the ice sheets of Greenland or Antarctica, melts, that water contributes to sea level rise.

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...

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...

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

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

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

Jason-1 Spacecraft Animation

The Argo stop-motion animation aims to inspire children (and adults) to engage with marine science. It is quirky, fun and informative at the same time. The animation explains what an Argo float is,...
