OSTM/Jason-2 - Data/ground track animation

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.

Launching aboard the joint U.S.-European Sentinel-6 Michael Freilich satellite is NASA’s next instrument that will help improve weather forecasting.

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

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

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...

Watching Our Oceans

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.

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.

Karl and Seymour learn how carbon dioxide is formed in this sketch from The Lollygaggers, a global warming sketch comedy.

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...

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 Level Isn't Level - Why it matters

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.

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.

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,...

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...
