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…

USA Today, July 9, 2013 Featuring: J.P. Nicot Texas’ current drought is caused by changes in ocean circulation patterns such as La Nina, anthropogenic climate change, and other factors. One thing intensifying the drought’s impact is hydraulic fracturing. Water consumption for fracking in the state jumped 125% in three years and will continue to increase…

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…

Groundwater depletion is a massive problem worldwide, but aside from hydrogeologists and farmers, how many people are aware of it? This year’s Oliver Distinguished Lecturer, Tom Gleeson of McGill University, wants to make sure both the problem and its potential solutions are well understood—so well understood, they can even be explained at a cocktail party….

How to Build a Smarter Rock

Joel Johnson of the Jackson School has crafted metal rocks to mimic a natural stone’s shape and density, and then inserted custom-made electronics to measure and record the faux rock’s movements in real streams and rivers. The mission: to better understand how waterways move tons of rock and other sediment downstream. Improving sediment transport models…

With her research interests and enthusiasm flowing forth like a raging river when she speaks, it’s no surprise that Kevan Moffett studies the dynamic role of water in the earth sciences. As she begins her career at the Jackson School of Geosciences, Moffett will focus on the fields of hydrogeology and ecohydrology, exploring the relationships…

Perhaps the only positive thing about the 2011 drought in Texas, the state’s worst single-year drought in history, is that it ended up being the mother of all teaching moments. The lessons learned are not pleasant, but addressing them will give the state a fighting chance when the next major drought comes around.

With the rapid disappearance of its protective buffer of wetlands, New Orleans is becoming more vulnerable to storms every year. But recent research has revealed important clues about how to shore up these vanishing wetlands and generated new optimism about saving the delta.
