Unexpected Basal Ocean Melting in East Antarctica

Nature Communications, August 24 The floating Shirase Ice Tongue (a long and narrow projection of ice, connected an ice basin about¬†the size of the United Kingdom) in Queen Maud Land, East Antarctica, has revealed surprisingly high basal melt rates of 7 to 16 m per year. These rates equal or surpass the melting rate underneath […]

Basal Melting of Antarctic Ice Shelves

Nature Geoscience, August 10 Between 1994 and 2018, Antarctic ice shelves (floating ice connected to the land-based Antarctic ice sheet) lost close to 3960 Gt of ice. Many ice shelves bordering Antarctica lose mass through ocean-driven melting at their base. This study builds on previous work by using higher density satellite radar measurements, enabling far […]
