Geologist John Goodge studies the 2% of Antarctica not covered by ice, focusing on the Transantarctic Mountains. Supported by the US Antarctic Program, his team collects rock samples to understand Antarctica's formation and history. They face challenges like harsh weather and aircraft availability. Back at the University of Minnesota Duluth, they analyze samples using a scanning electron microscope, revealing insights into ancient supercontinents. Goodge emphasizes Antarctica's importance in studying global climate change and ice sheet stability, providing a framework to predict future changes.
