Watching Our Oceans

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...

A key ocean observation satellite has been named after Earth scientist Michael Freilich

TOPEX/Poseidon Instruments

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

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

Sea Level Isn't Level - Why it matters

Oceans of Climate Change

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

Changing conditions in the Pacific have stirred up Earth’s largest ocean and redistributed its heat, piling up warm waters along U.S. Western shores and raising sea level in the process.

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

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

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.

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.

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

SSH and SST - Global

For NASA scientist Severine Fournier, studying our planet knows no borders.

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.

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...

El Niño/La Niña - (12/1996 - 01/2000)

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

TOPEX/Poseidon Ground Tracks

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

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

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,...
