Sea Level

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

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...

Ionospheric Total Electron Content

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...

A look at how NASA is dealing with the threat of sea level rise to its coastal infrastructure.

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...
