Glaciology
A new study reveals violent underwater vortices beneath Antarctica's ice shelves that draw warm water to the surface, accelerating ice melt. These 'storms' are driven by the freezing and melting of sea ice, displacing protective cold water layers. The findings highlight rapid changes in the West Antarctic Ice Sheet, threatening global sea levels.

Researchers have identified 85 previously unknown lakes hidden under Antarctica's vast ice sheet, increasing the known total to over 400. The discovery, made using advanced satellite and radar data, highlights the continent's complex subglacial hydrology. These findings could provide insights into ice sheet stability and global sea level rise.
