TOPEX/Poseidon Ground Tracks

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

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...

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...

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.

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...

This artist's concept show Jason-3 over the Amazon.

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...

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.

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...
