Newly Discovered Lake May Hold Secret to Antarctic Ice Sheet’s Rise and Fall

A group of nine scientists dressed for polar research pose in front of a propeller plane on the ice

Scientists investigating the underside of the world’s largest ice sheet in East Antarctica have discovered a city-size lake whose sediments might contain a history of the ice sheet since its earliest beginnings. That would answer questions about what Antarctica was like before it froze, how climate change has affected it over its history, and how… Continue Reading Newly Discovered Lake May Hold Secret to Antarctic Ice Sheet’s Rise and Fall

UT Graduate Student Research Solves Plate Tectonics Mystery

Painting of Earth's crust with two plates subducting into the Earth. Above each subduction zone are volcanoes and mountains.

The longstanding enigma of how tectonic plates can break Earth’s rock-hard shell may have been solved by a recent graduate student at The University of Texas at Austin who caught the Earth in the act of starting a new tectonic conveyor belt off the coast of New Zealand. The world’s tectonic conveyor belts – called… Continue Reading UT Graduate Student Research Solves Plate Tectonics Mystery

Are Deep Fluids Behind the Largest Earthquakes? ‘Not So Fast!’ Says UT Graduate Student

A fishing boat sits among litter strewn streets and damaged buildings..

Sandwiched between tectonic plates are layers of material that show up as thin shadows on seismic tomography, a kind of CT scan of the Earth. For years, scientists assumed the anomalies were signs of highly pressurized water squeezed into densely packed rock and that the fluid acted as a kind of hair-trigger on earthquake faults.… Continue Reading Are Deep Fluids Behind the Largest Earthquakes? ‘Not So Fast!’ Says UT Graduate Student
