A new Antarctic map reveals thousands of hidden landforms beneath the ice, improving climate and sea-level predictions.
A new, high-resolution map of Antarctica’s subglacial terrain, published in Science on January 15, 2026, reveals tens of thousands of previously unknown valleys, mountains, and channels beneath the ice using satellite data and a new modeling technique called Ice Flow Perturbation Analysis.
The map, which captures features from 2 to 30 kilometers in size, improves understanding of how ice flows and may respond to climate change, aiding sea-level rise projections.
While limited in detecting smaller or larger landforms, the study marks a major advance in polar science and highlights the importance of future surveys.
