New Map Uncovers Antarctica’s Hidden Landscape
Scientists have produced the most detailed map to date of the terrain lying beneath Antarctica’s vast ice sheet, revealing a complex landscape of mountains, valleys, ridges and deep basins hidden for millions of years.
How the Mapping Was Done
The map was created by combining satellite data, ice thickness measurements and advanced modelling techniques that track how ice flows over the bedrock below. By analysing subtle changes in ice movement, researchers were able to estimate the shape and features of the land buried under kilometres of ice.
Why the Findings Matter
Understanding Antarctica’s subglacial landscape is critical for climate research. The shape of the bedrock plays a major role in how ice sheets move and melt. More accurate maps will help scientists improve predictions about ice loss and future sea-level rise as global temperatures increase.
Insights Into Ancient Antarctica
The newly revealed terrain suggests that Antarctica once had a varied landscape similar to mountain regions elsewhere in the world before it was covered by ice. Researchers say the findings also offer clues about the continent’s geological history and long-term climate evolution.
