Watching Our Oceans

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.

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.

Sea Surface Height - Global Average from 1993 - 2011.

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

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

After living in coastal Virginia and seeing the effects of climate change firsthand, Ben Hamlington is now researching sea level rise at NASA JPL.

Experts from NASA, ESA, EUMETSAT, and NOAA discuss the upcoming launch of Sentinel-6 Michael Freilich in a recorded live broadcast

Jason-3 Animation

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

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

TOPEX/Poseidon Instruments

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...

Jason-1 Spacecraft Animation

The Jason-3 satellite, launched on January 17, 2016, is allowing scientists to continue a 23-year record of crucial ocean monitoring.

Karl and Seymour learn how carbon dioxide is formed in this sketch from The Lollygaggers, a global warming sketch comedy.

For NASA engineer Shannon Statham, building spacecraft is all about being creative.

Oceans of Climate Change

On Aug. 26, 2015 at 9:30 a.m. PT, NASA hosted a media teleconference to discuss recent insights on sea level rise and the continuing challenge of predicting how fast and how much sea level will ris...

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.

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...
