Each summer, scientists from the University of Texas Institute for Geophysics run one of the world’s most advanced field courses for marine geosciences and geophysics, offering valuable hands-on experience for Jackson School students.  

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.

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…

Peter Flemings was on a family vacation hiking in the White Mountains in New Hampshire when his cell phone rang. It was U.S. energy secretary Stephen Chu’s assistant. Could he join a web conference with Secretary Chu, and dozens of scientists from government, academia and industry, in a few hours? After packing up and making…

Andrew Smith studies undersea gas vents, large volcano-like features on the seafloor that spew plumes of oil and gas into the ocean. Scientists have long been interested in them because many contain large amounts of gas hydrate, an icy substance made of natural gas and water. Gas hydrates might be mined someday as an alternative…

This past summer, a team of scientists from the University of Texas at Austin completed the first of a series of expeditions in the Gulf of Mexico surveying potential offshore storage sites for carbon dioxide (CO2). In the process, they tested out a new type of seismic instrument designed to reveal geologic layers and structures…

AUSTIN, Texas — 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. Follow our rapid response field blog with live updates from the ship. The team will collaborate this month with…

The Leading Edge, August 2012 Featuring: Sean Gulick, John Goff, Marcy Davis, Dan Duncan, Steffen Saustrup

See shipwrecks, deep sea life and gas seeps in the Gulf of Mexico during an expedition led by University of Texas at Austin scientist Jamie Austin. Live video feeds from remotely operated vehicles (ROVs) with high-definition cameras put anyone with an Internet-enabled computer right in the middle of the action.

Visions of sugar plums they were not, but you could forgive Jamie Austin for feeling as if he were dreaming. On his screen he saw what looked like big glass bowls sparkling in the headlamps of the remotely operated vehicle (ROV). At another site, he saw rows of partially buried clay jars, some with eel heads…
