Hidden East Antarctic Basin Revealed Beneath the Ice

Researchers analyzing data compiled from geology, gravity, magnetic measurements and crust models report a massive, previously unrecognized structure beneath two miles of Antarctic ice—the East Antarctic Fan-shaped Basin Province—integrating Wilkes and Aurora subglacial basins with Lake Vostok into a single feature. The formation, likely due to distributed rotational extension over millions of years, could significantly influence ice flow and landscape evolution across about half of the East Antarctic Ice Sheet, though further corroboration is needed.

Antarctic Permafrost Thaw and Ice Sheet Collapse: A Looming Climate Crisis

Permafrost in Antarctica's Dry Valleys is releasing CO2, while the East Antarctic Ice Sheet (EAIS) is approaching runaway melting and the West Antarctic Ice Sheet (WAIS) has collapsed in the recent past.

Unveiling Antarctica's Ancient Subglacial Secrets

Scientists have discovered a well-preserved ancient landscape beneath the East Antarctic Ice Sheet (EAIS) using satellite data and radio-echo-sounding capabilities. The landscape, formed by ancient rivers around 14 million years ago, remained remarkably unchanged despite the glaciation of the continent. The findings provide insights into the early formation and history of the EAIS and could help understand its response to climate change. The researchers believe there may be more hidden features beneath Antarctica's ice waiting to be discovered.

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.
