NASA Climate Watcher Waves Goodbye

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...

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

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.

Sea Level Isn't Level - Why it matters

Sea Surface Height - Global Average from 1993 - 2011.

Decades of Discovery - How altimeters help us every day.

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 scientist Severine Fournier, studying our planet knows no borders.

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

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

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

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

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.

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...

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

Growing up in landlocked Zimbabwe, NASA JPL engineer Shailen Desai was far from the ocean but still experienced its effects on the climate. Now, he is contributing to an international effort to tra...

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.

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...

Watch the Jason-3 Science Briefing from Friday, Jan 15, 2016 - panelists discussed the science and research of the Jason-3 mission.

QuickTime VR of TOPEX/Poseidon

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

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

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