flag Scientists found ancient sediment moving under Antarctic ice, revealing processes that affect ice flow and climate predictions.

flag Scientists searching for ancient ice in Antarctica discovered sediment moving beneath the ice sheet, revealing complex subglacial processes that could affect ice flow and climate models. flag Using airborne radar, researchers identified a sediment layer formed over millions of years by ice flowing down a subglacial mountain range, likely driven by geothermal heat. flag The findings, tied to ongoing efforts to find ice older than 800,000 years, suggest that sediment transport may influence ice sheet stability and the preservation of climate records, with implications for understanding future sea level rise.
