Unveiling an Ancient Landscape: Antarctica's Hidden Secrets Revealed

Satellite data has revealed an ancient, river-carved landscape preserved beneath East Antarctica's ice sheet, providing a snapshot of the region before glaciers covered the continent. The data shows that a patch adjacent to the Aurora and Schmidt subglacial basins has remained largely unscathed for up to 34 million years. The landscape consists of three blocks of land separated by U-shaped valleys, likely formed when the ancient supercontinent Gondwana broke up. Understanding the shape of the landscape will help researchers predict the fluctuations of the East Antarctic ice sheet in a warming world.

Unveiling the Impact of Thinning Ice Sheets on Subglacial Waters

A multinational team of researchers has used data from multiple sources to map the pathways of warm water that reaches the cavity of East Antarctica's Totten Glacier. The study provides valuable insights into the physical processes controlling the melting of the glacier and highlights the importance of bathymetry and regional circulation in regulating ocean heat transport. The findings can help improve modeling and understanding of the glacier's contribution to global sea-level rise.
