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

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.

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...

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,...

This video discusses the water cycle, which is the movement of water around the Earth, and its importance to life. Changes to the water cycle affect climate and vice versa.

Decades of Discovery - How altimeters help us every day.

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