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.
From 2009 through 2019, NASA’s Operation IceBridge flew above the Arctic, Antarctic and Alaska, gathering data on the height, depth, thickness, flow and change of sea ice, glaciers and ice sheets.
A new study finds that the Greenland Ice Sheet has lost 3.8 trillion tons of ice between 1992 and 2018.
Adapting to rising seas will require a broader understanding of coastal systems, and of human responses to sea-level rise, a new study says.
An elephant seal helps scientists understand how the ocean transports heat between its upper and lower layers — important for estimating how much heat the ocean can absorb.
The U.S. and Europe are working together on the first 10-year mission to study global warming's effect on the oceans, extending sea level records to nearly 40 years.
