Dr. Eric Rignot is the principal scientist for the Radar Science and Engineering section at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and a professor of Earth System Science at the University of California, Irvine. He specializes in radar interferometry and polarimetry as applied to the geosciences. Rignot also is the principal investigator on several NASA-funded projects, investigating the Greenland and Antarctic ice sheets, interactions between ice shelves and the ocean and the retreat of glaciers in Patagonia. He's a member of the American Geophysical Union and the International Glaciological Society, and is frequently interviewed by the media.
Scientists have combined NASA Earth satellite observations with data on human activities to map locations where freshwater is changing around the globe and to determine why.
Revised dates have been set for the prelaunch briefing and launch of GRACE-FO, NASA's latest Earth-observing satellite mission.
Operation IceBridge, NASA’s longest-running airborne mission to monitor polar ice change, concluded this year’s springtime survey of Arctic sea and land ice.
GRACE Follow-On's unique satellite view of underground water will be valuable in creating one of the most important U.S. tools for tracking drought throughout the nation.
Melting polar ice doesn't raise global sea level evenly, like filling a sink. GRACE-FO can help scientists understand differences in sea level rise on the world's coastlines.
