Seismic events are not rare occurrences on Antarctica, where sections of the frozen desert can experience hundreds of micro-earthquakes an hour because of ice deformation. Some scientists call them icequakes. But shortly after an 8.8-magnitude earthquake struck Chile on Feb. 27, 2010, the ice sheets in Antarctica vibrated more than usual.
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.
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… » Continue Reading
AUSTIN, Texas — A new reconstruction of climate in the South Pacific during the past 446 years shows rainfall varied much more dramatically before the start of the 20th century than after. The finding, based on an analysis of a cave formation called a stalagmite from the island nation of Vanuatu, could force climate modelers to adjust… » Continue Reading
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… » Continue Reading
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… » Continue Reading
An international team of 34 scientists sets sail today aboard the scientific ocean drilling vessel JOIDES Resolution to collect sediments in the Gulf of Alaska and investigate the interactions between long-term global climate change and the simultaneous growth of mountain belts. The team is co-led by Sean Gulick, research associate professor at The University of… » Continue Reading
AUSTIN, Texas — A massive explosion at a fertilization plant rocked the small town of West, Texas, late Wednesday night, sending more than 150 people to area hospitals and leaving a yet-unknown number of fatalities. The University of Texas at Austin has a wide variety of experts available with backgrounds ranging from disaster preparedness and… » Continue Reading
A rapid response science team from the University of Texas at Austin’s Institute for Geophysics will help map the impact of Hurricane Sandy on the beach/barrier systems off the south shore of Long Island.
To celebrate the successful exploration of Vesta, Dawn mission scientists and engineers will share mission stories and answer questions submitted via Facebook, Twitter and email in a live, interactive video event.
