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...

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

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