SSH and SST - Pacific Ocean

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

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...

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

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.

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

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

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

Sea Surface Height - Global Average from 1993 - 2011.

Fathoming the forces that determine global sea levels can be daunting. We present a guide to the basics of ocean surface topography.

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,...

OSTM/Jason-2 - Data/ground track animation

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

The Jason-2 satellite sees something brewing in the Pacific. Researchers say it could be a significant El Niño with implications for global weather and climate.

OSTM/Jason-2 - All instruments plus data animation

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

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...

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

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

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.

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...

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.
