Antarctica's Hidden World: New Map Reveals Subglacial Hills and Channels
- •Researchers have unveiled a detailed map of Antarctica's subglacial landscape, previously hidden beneath thick ice.
- •The map, published in Science, uses satellite data and glacier movement analysis to reveal unknown hills, valleys, and a massive channel.
- •Lead author Dr. Helen Ockenden explains that ice movement reveals underlying terrain, similar to how water flow indicates riverbed rocks.
- •A significant discovery is a 400 km long, 50-meter deep, 6 km wide channel in the Maud Subglacial Basin.
- •The new Ice Flow Perturbation Analysis (IFPA) method offers a clearer picture than previous radar surveys, despite some limitations.
Why It Matters: A new map provides unprecedented detail of Antarctica's hidden subglacial landscape, revealing unknown features.
