Researchers for the first time have discovered that erosion caused by glaciation during ice ages can, in the right circumstances, wear down mountains faster than plate tectonics can build them.

Post-Sandy Survey Shows a Polluted but Generally Intact Barrier System off Long Island

Dec. 11, 2013

As coastal communities continue to rebuild in the wake of Hurricane Sandy, scientists at this week's annual meeting of the American Geophysical Union offer some encouraging news: The storm did not seriously damage the offshore barrier system that controls erosion on Long Island.

Model Suggests Ocean Currents Shape Europa's Icy Shell in Ways Critical for Potential Habitats

Dec. 3, 2013

In a finding of relevance to the search for life in our solar system, researchers at The University of Texas at Austin's Institute for Geophysics, the Georgia Institute of Technology, and the Max Planck Institute for Solar System Research have shown that the subsurface ocean on Jupiter's moon Europa may have deep currents and circulation patterns with heat and energy transfers capable of sustaining biological life.

Coastal Antarctic Permafrost Melting Faster Than Expected

July 24, 2013

For the first time, scientists have documented an acceleration in the melt rate of permafrost, or ground ice, in a section of Antarctica where the ice had been considered stable. The melt rates are comparable with the Arctic, where accelerated melting of permafrost has become a regularly recurring phenomenon, and the change could offer a preview of melting permafrost in other parts of a warming Antarctic continent.

Scientists Image Vast Subglacial Water System Underpinning West Antarctica's Thwaites Glacier

July 9, 2013

In a development that will help predict potential sea level rise from the Antarctic ice sheet, scientists from The University of Texas at Austin's Institute for Geophysics have used an innovation in radar analysis to accurately image the vast subglacial water system under West Antarctica's Thwaites Glacier. They have detected a swamp-like canal system beneath the ice that is several times as large as Florida's Everglades.
