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

Recorded live broadcast of Sentinel-6B, launched at 9:21 p.m. PST, Sunday, Nov. 16 (12:21 a.m. EST, Monday, Nov. 17) aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

Our World: How High is the Ocean?

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.

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

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

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.

Watching Our Oceans

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

SSH and SST - Pacific Ocean

NASA and its U.S. and international partners have teamed up to launch a new Earth-observing satellite called Sentinel-6B that will measure sea surface height of most of the planet’s ocean. These ob...

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

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.

SSH and SST - Global

NASA and its partners announced the renaming of the mission, previously known as Sentinel-6A/Jason-CS.

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,...

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

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.
