AUSTIN, Texas  A new study correlates a series of small earthquakes near Snyder, Texas between 2006 and 2011 with the underground injection of large volumes of gas, primarily carbon dioxide (CO2) a finding that is relevant to the process of capturing and storing CO2 underground.

A team of U.S. and U.K. scientists has found geologic evidence that casts doubt on one of the conventional explanations for how Antarctica's ice sheet began forming. Ian Dalziel, research professor at The University of Texas at Austin's Institute for Geophysics and professor in the Jackson School of Geosciences, and his colleagues report the findings today in an online edition of the journal Geology.

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.
