Jason-3 Animation

Greenland and Antarctica are home to most of the world's glacial ice – including its only two ice sheets – making them areas of particular interest to scientists.

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

Watch the Jason-3 Science Briefing from Friday, Jan 15, 2016 - panelists discussed the science and research of the Jason-3 mission.

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...

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...

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.

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...

A look at how NASA is dealing with the threat of sea level rise to its coastal infrastructure.

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

Jason-1 Poster

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.
