TOPEX/Poseidon Ground Tracks

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...

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

Recorded live launch broadcast of Sentinel-6 Michael Freilich

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

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...

Decades of Discovery - How altimeters help us every day.

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

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

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

Here we provide side by side comparisons of Pacific Ocean sea surface height (SSH) anomalies of what is presently happening in 2015 with the Pacific Ocean signal during the famous 1997 El Niño.

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.

Watching Our Oceans

Sea levels across the globe are rising as a result of a changing climate — and the rate at which they are rising is accelerating. NASA Science Live was recorded Tuesday, Nov. 17, 2020, and featured...

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...

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

OSTM/Jason-2 - All instruments plus data animation

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

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

SSH and SST - Global

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.

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.

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...
