Scientists Cast Doubt on Theory of What Triggered Antarctic Glaciation

Scientists Cast Doubt on Theory of What Triggered Antarctic Glaciation

A team of U.S. and U.K. scientists has found geologic evidence that casts doubt on one of the conventional explanations for how Antarctica’s ice sheet began forming. Ian Dalziel, research professor at The University of Texas at Austin’s Institute for Geophysics and professor in the Jackson School of Geosciences, and his colleagues report the findings…   » Continue Reading

Scientists Image Vast Subglacial Water System Underpinning West Antarctica’s Thwaites Glacier

Scientists Image Vast Subglacial Water System Underpinning West Antarctica’s Thwaites Glacier

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

Planetary Scientists Solve 40-Year-Old Mysteries of Mars’ Northern Ice Cap

Planetary Scientists Solve 40-Year-Old Mysteries of Mars’ Northern Ice Cap

Scientists have reconstructed the formation of two curious features in the northern ice cap of Mars — a chasm larger than the Grand Canyon and a series of spiral troughs — solving a pair of mysteries dating back four decades while finding new evidence of climate change on Mars.

Scientists Probe Antarctic Glaciers for Clues to Past and Future Sea Level

Scientists from the U.S., U.K. and Australia have teamed up to explore two of the last uncharted regions of Earth, the Aurora and Wilkes Subglacial Basins, immense ice-buried lowlands in Antarctica with a combined area the size of Mexico. The research could show how Earth's climate changed in the past and how future climate change…   » Continue Reading
