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

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,...

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

Sentinel-6 Michael Freilich will join a long-standing family of Earth observing satellites from NASA and European partners.

Sea level rise is an indicator that our planet is warming. When ice on land, such as mountain glaciers or the ice sheets of Greenland or Antarctica, melts, that water contributes to sea level rise.

One of the best ways to understand Earth's ocean is from the perspective of space.

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...

After living in coastal Virginia and seeing the effects of climate change firsthand, Ben Hamlington is now researching sea level rise at NASA JPL.

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...
