Watching Our Oceans

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

Recorded live broadcast of Sentinel-6B, launched at 9:21 p.m. PST, Sunday, Nov. 16 (12:21 a.m. EST, Monday, Nov. 17) aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

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,...

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

Jason-CS/Sentinel-6 - How they will work

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...

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

Our World: How High is the Ocean?

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.

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

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...

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

El Niño is characterized by unusually warm ocean temperatures in the eastern equatorial Pacific. The warmer water associated with El Niño displaces colder water in the upper layer of the ocean caus...

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

On the left is Sea Surface Height Anomalies (SSHA) relative to the sea level mean (1993-2018). On the right is Global Mean Sea Level (GMSL) with the sea level trend as the straight line. The data a...

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...

Jason-1 Spacecraft Animation

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

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

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

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...

OSTM/Jason-2 - Data/ground track animation

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...
