Scientists Identify 2-Mile-Deep East Antarctic Basin Province, Reshaping Ice-Sheet Risk

Summary
A Nature study says several East Antarctic features long studied separately—including the Wilkes and Aurora subglacial basins and Lake Vostok—form one vast structure buried about 2 miles beneath the ice.
Researchers mapped the newly named East Antarctic Fan-shaped Basin Province by combining geological observations, gravity and magnetic measurements, and crustal models, pointing to formation by distributed rotational extension over millions of years.
About half of the East Antarctic Ice Sheet overlies those basins, making the structure a major control on ice flow, landscape evolution, and hydrological processes beneath the continent.
The finding still needs further corroboration, but scientists say it could sharpen understanding of how Antarctica formed and how its three major ice sheets may respond to a warming climate.
A colossal basin was just found under Antarctica's ice. What other massive secrets does our planet still conceal?
This new discovery impacts half the East Antarctic Ice Sheet. How does it change the timeline for future sea-level rise?
Antarctica's hidden water world resembles icy moons. Could its discovery guide our search for extraterrestrial life?
Discovery of the East Antarctic Fan-Shaped Basin Province: A Giant Subglacial Structure Redefining Ice Sheet Stability and Sea-Level Risk
Overview
In June 2026, researchers led by Dr. Egidio Armadillo discovered the Giant fan-shaped geological structure, now called the East Antarctic Fan-Shaped Basin Province (EAFBP), beneath East Antarctica. Supported by the Italian National Antarctic Research Program, this finding reveals a unique fan-shaped formation process deep under the ice. The EAFBP’s location and structure provide new insights into the continent’s hidden geology, opening up fresh opportunities to study Antarctica’s tectonic history and how it affects ice sheet dynamics. This discovery is expected to reshape geological maps and deepen our understanding of the region’s role in global climate systems.
