Ancient River Landscape Unearthed Beneath Antarctic Ice
Scientists have discovered an ancient river landscape hidden beneath the East Antarctic Ice Sheet, which existed between 34 million to 60 million years ago. The landscape, estimated to have been buried for 14 million to 34 million years, was found using satellites and ice-penetrating radar. Climate warming could result in ice retreat into this region for the first time in at least the last 14 million years, potentially revealing the preserved ancient landscape. The study provides insights into the past climate of Antarctica and the breakup of the Gondwana supercontinent.
