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...

Oceans of Climate Change

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

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.

Jason-1: LRA instrument

It's hard to "see" sea level rise by just looking at the ocean, but its effects are very real.

The Sentinel-6 Michael Freilich satellite sits in front of a testing chamber where mission team members tested whether the spacecraft could endure the loud sounds it will encounter during launch.

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...

Our World: How High is the Ocean?

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...
