SSH and SST - Indian Ocean

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.

El Niño/La Niña - (12/1996 - 01/2000)

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...

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.

SSH and SST - Global

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.

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

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.

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.

TOPEX/Poseidon Launch

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

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).

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...
