For decades, researchers seeking to understand global climate change have analyzed ice cores drilled deep within the Antarctic ice sheet. This ice traps chemicals and bubbles of ancient air that tell the story of how Earth’s climate has changed over time. To develop a precise climate record, researchers seek to find continuous ice that’s uninterrupted,… Continue Reading While Searching for the World’s Oldest Ice, Scientists Find Sediment Sneaking Under the Antarctic Ice Sheet
UT-Led Aerial Surveys Reveal Ancient Landscape Beneath East Antarctic Ice Sheet
Long before Antarctica froze over, rivers carved valleys through mountains in the continent’s east. Millions of years later, researchers have discovered a remnant of this ancient highland landscape thanks to an aerial survey campaign led by the University of Texas Institute for Geophysics (UTIG). The findings were described by researchers at Durham University and Newcastle… Continue Reading UT-Led Aerial Surveys Reveal Ancient Landscape Beneath East Antarctic Ice Sheet
Highest Honor in Antarctic Exploration Goes to Ian Dalziel
Ian Dalziel of The University of Texas at Austin has been honored with the Polar Medal — the United Kingdom’s top award for polar exploration. The medal recognizes Dalziel’s contributions to Antarctic geology, including discoveries about the icy continent’s ancient past and the fragility of its ice sheet today. The award will be presented by… Continue Reading Highest Honor in Antarctic Exploration Goes to Ian Dalziel
Underwater Snow Gives Clues About Europa’s Icy Shell
Below Europa’s thick icy crust is a massive, global ocean where the snow floats upwards onto inverted ice peaks and submerged ravines. The bizarre underwater snow is known to occur below ice shelves on Earth, but a new study shows that the same is likely true for Jupiter’s moon, where it may play a role… Continue Reading Underwater Snow Gives Clues About Europa’s Icy Shell
Newly Discovered Lake May Hold Secret to Antarctic Ice Sheet’s Rise and Fall
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
