Far fewer lakes below the East Antarctic Ice Sheet than previously believed

In the course of an extensive Antarctic expedition, researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research recently investigated several lakes beneath Recovery Glacier that had been previously detected by satellite remote sensing. The experts found very few substantial bodies of water, which is a surprising result.

The findings are from a major climate assessment known as the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE), and are published today in Nature. It is the most complete picture of Antarctic ice sheet change to date - 84 scientists from 44 international organisations combined 24 satellite surveys to produce the assessment.

Irreversible ocean warming threatens the Filchner-Ronne Ice Shelf

By the second half of this century, rising air temperatures above the Weddell Sea could set off a self-amplifying meltwater feedback cycle under the Filchner-Ronne Ice Shelf, ultimately causing the second-largest ice shelf in the Antarctic to shrink dramatically. Climate researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), recently made this prediction in a new study, which can be found in the latest issue of the Journal of Climate, released today. In the study, the researchers use an ice-ocean model created in Bremerhaven to decode the oceanographic and physical processes that could lead
