Watching Our Oceans

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.

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,...

For NASA engineer Shannon Statham, building spacecraft is all about being creative.

Our World: How High is the Ocean?

Decades of Discovery - How altimeters help us every day.

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

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

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.

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...

Sea levels across the globe are rising as a result of a changing climate — and the rate at which they are rising is accelerating. NASA Science Live was recorded Tuesday, Nov. 17, 2020, and featured...

The ocean-observing Sentinel-6 Michael Freilich satellite launched from Vandenberg Air Force Base in California aboard a SpaceX Falcon 9 rocket on Nov. 21, 2020 at 12:17 p.m. EST

Sea Level Isn't Level - Why it matters

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

Our planet is changing. Our ocean is rising. And it affects us all. That’s why a new international satellite will continue the decades-long watch over our global ocean and help us better understand...

The Jason-2 satellite sees something brewing in the Pacific. Researchers say it could be a significant El Niño with implications for global weather and climate.

Karl and Seymour learn how carbon dioxide is formed in this sketch from The Lollygaggers, a global warming sketch comedy.

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

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

Jason-CS/Sentinel-6 - How they will work

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

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