Story summary

Scientists unveiled a detailed map of Antarctica's subglacial landscape, revealing mountains, valleys, and channels beneath the ice.
Led by Helen Ockenden of the University of Edinburgh, the team used Ice Flow Perturbation Analysis (IFPA) to infer bedrock features from satellite observations.
The findings, published in Science, identify over 71,000 subglacial hills and deep channels, reshaping understanding of ice flow and sea-level rise.
