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...

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

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...

Jason-1 Launch - Artists Concept

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

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

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.

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,...
