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.
Satellite data on the movement of water on Earth helps to improve the accuracy of moisture maps and forecasts.
The shape of the ground beneath Denman Glacier, which is melting from the bottom up, makes it particularly vulnerable to seawater intrusion.
Greenland and Antarctica are melting—but how quickly and which areas are most affected? Nearly 20 years of satellite data provide key insights into these questions.
The two regions have lost 6.4 trillion tons of ice in three decades; unabated, this rate of melting could cause flooding that affects hundreds of millions of people by 2100.
