Summary
Scientists have created a new detailed map showing the landscape beneath Antarctica's ice. This research discovered many unknown hills and ridges, offering more insight into how Antarctica may respond to climate change and affect sea-level rise.
Key Facts
- Researchers used satellite data and glacier movement physics to create the new map.
- The map reveals thousands of previously unknown hills and ridges beneath Antarctica's ice.
- It provides a clearer view of Antarctica's hidden mountain ranges than ever before.
- Understanding the landscape can help predict how Antarctica might react to climate change.
- Traditional methods used radar but left gaps due to spacing between survey lines.
- The new approach combined satellite data and ice movement studies to fill in these gaps.
- A significant discovery includes a deep, long channel in the Maud Subglacial Basin.
- The new map is a significant advance but contains some uncertainties due to the assumptions in the methods used.
