Lifeless Waters

Analysis reveals how limited natural buffering of Mississippi River pollution is likely contributing to Gulf of Mexico “dead zone” By John Williams “For whatever we lose…, it’s always our self we find in the sea,”the poet E.E. Cummings once wrote. Cummings was no water-quality expert, but his line unintentionally touches upon a major environmental problem:…

In 2012, professor Zong-Liang Yang was in the Netherlands speaking at a workshop on extreme weather. It was the year after the worst recorded single-year drought in Texas history. Yang made colleagues an offer: hold the next biannual conference in Texas and the University of Texas at Austin would host it. Last week, Yang and…

A new method of measuring the interaction of surface water and groundwater along the length of the Mississippi River network adds fresh evidence that the network’s natural ability to chemically filter out nitrates is being overwhelmed. The research by hydrogeologists at The University of Texas at Austin, which appears in the May 11 edition of…

As the bitter 2011 Texas drought stretched on into its third year, the Jackson School of Geoscience’s Center for Integrated Earth System Science (CIESS) hosted its third annual Water Forum. The forum, held Oct. 14 -15, 2013, focused on the latest research on droughts and other extreme weather events and provided a forum for discussion…

Joseph Levy was preparing for a season of scientific research in Antarctica last week when he got the call: Stand down. Dr. Levy, a research associate at UT Austin’s Institute for Geophysics, is studying the climate history of the dry valleys of Antarctica by analyzing buried ice sheets that have been frozen since the last ice age…

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…

Austin American-Statesman, July 14, 2013 Featuring: Dusty Schroeder, Don Blankenship, Duncan Young, UTIG A team of University of Texas researchers recently discovered a swamplike system of water under an Antarctic glacier the size of New Mexico — a finding that might hold the key to how quickly the polar ice will melt and the seas…

A team of scientists led by Ian Dalziel from the Institute for Geophysics has found geologic evidence that casts doubt on one of the conventional explanations for how Antarctica’s ice sheet began forming. The team discovered an ancient volcanic arc that might have prevented the creation of the Antarctic Circumpolar Current.

LiveScience, July 10, 2013 Featuring: Dusty Schroeder, Don Blankenship A sprawling network of low-lying canals, similar to a swamp, hides under Antarctica’s Thwaites Glacier, a new study finds. The fast-flowing Thwaites Glacier is one of the largest ice streams in West Antarctica. Scientists think Thwaites could significantly retreat in the next 20 years, adding to global sea level…

Rising Sea Level Tied to Faster Melt

Wall Street Journal, June 2, 2013 Featuring: Clark Wilson Accelerated melting of polar ice sheets and mountain glaciers was the driving factor behind a rise in the global sea level of 16.8 millimeters, or about two-thirds of an inch, between 2005 and 2011, according to a study published Sunday in Nature Geoscience. The study resolves long-standing…
