Frozen Flows

Written on .

UCI research shows glaciers are moving faster than once thought. Brittany Hanson, Orange County Register Glaciers are fast – much faster than scientists previously thought – and their speeds are increasing, according to a UC Irvine research team mapping ice movement in Antarctica for NASA. “When they (speed up), it’s not a trickle,” said Eric Rignot, a UC Irvine professor of Earth System Science and lead project researcher. They increase in speed by three, or eight – sometimes...

Chile, Greenland Glacier Study: $2 million

Written on .

Pat Brennan, Orange County Register A UC Irvine scientist will receive a $2.2 million grant to study glaciers in Chile and Greenland, potentially shedding further light on the links among vanishing glaciers, rising sea levels and a warming planet. Eric Rignot, a researcher at UC Irvine and the Jet Propulsion Laboratory in Pasadena who specializes in polar ice, will measure subtle changes in gravity during helicopter flights over the glaciers and ice fields of Patagonia. He’ll also...

Mapping Antarctic Ice In Motion

Written on .

Felicity Barringer, The New York Times Put the arguments over how fast Antarctic ice is melting to one side for the moment. The latest study of the southern continent, by a group of scientists led by Eric Rignot of the University of California, Irvine, shows how fast the ice rivers are moving and where they are going. The map of ice in motion, which traces parts of the eastern Antarctic region that have previously been hard to see, offers a new and powerful tool for...

Warmer ocean speeding Greenland glacier melt

Written on .

Glaciers in West Greenland are melting 100 times more rapidly at their end points beneath the ocean than they are at their surfaces, according to a UC Irvine/NASA study. Alan Buis, NASA\’s Jet Propulsion Laboratory Glaciers in West Greenland are melting 100 times more rapidly at their end points beneath the ocean than they are at their surfaces, according to a UC Irvine/NASA study published online this week in Nature Geoscience. The study results suggest this undersea melting caused...
