Scientists identified a vast fan-shaped network of hidden basins beneath East Antarctica’s ice sheet, revealing that several previously known subglacial features form part of one large geological structure. The discovery reshapes understanding of the continent’s buried landscape.
Radar and satellite imaging techniques allow researchers to map terrain beneath kilometers of ice without surface drilling. The fan-shaped arrangement suggests interconnected basins shaped by ancient geological processes.
Subglacial topography influences how ice flows toward the ocean, with implications for sea level rise projections. Linking isolated known features into a single massive structure provides a more coherent model of Antarctic bedrock.
The finding emerged from international collaboration analyzing decades of geophysical data. Scientists plan further surveys to determine how the hidden basins affect ice sheet stability under warming climate conditions.
