Watching Our Oceans

Our World: How High is the Ocean?

On Aug. 26, 2015 at 9:30 a.m. PT, NASA hosted a media teleconference to discuss recent insights on sea level rise and the continuing challenge of predicting how fast and how much sea level will ris...

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...

Watch the Jason-3 Mission Briefing from Friday, Jan 15, 2016 - panelists gave an overview of the Jason-3 mission.

This visualization shows total sea level change between 1992 and 2019, based on data collected from the TOPEX/Poseidon, Jason-1, Jason-2, and Jason-3 satellites. Blue regions are where sea level ha...

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

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.

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

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

A SpaceX Falcon 9 rocket lifts off from Space Launch Complex 4 at Vandenberg Air Force Base carrying the Jason-3 spacecraft. Liftoff was at 10:42 a.m. PST (1:42 p.m. EST).

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...

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

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 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

To provide scientists with essential information about global and regional changes in the seas, NASA will launch the Jason-3 satellite from Vandenberg Air Force Base in California.

Sea Level Isn't Level - Why it matters

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

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

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,...
