Šta se sve krije ispod antarktičkog ledenog carstva
Naučnici su sa do sada neviđenom preciznošću mapirali stenovitu podlogu ispod ogromnog ledenog pokrivača Antarktika, otkrivajući skrivene geološke strukture koje oblikuju glečere.
TL;DR
- A new study has precisely mapped the rocky ground beneath Antarctica's vast ice sheet.
- The map reveals hidden mountains, valleys, lakes, and basins that influence ice flow.
- Researchers combined satellite imagery, ice thickness data, and ice flow analysis to create the map.
- The study uncovered tens of thousands of previously unknown hills and ridges, along with detailed canyon structures.
- A particularly deep channel, approximately 50 meters deep and 6 kilometers wide, was identified in the subglacial basin Mod.
- The detailed topography helps scientists understand how the ice sheet has evolved and interacts with the bedrock.
- Improved understanding of these processes can lead to more accurate projections of ice melt and sea-level rise.
