Briefings

A 2026 article reports that the Kronshtadskiy subglacial lake near East Antarctica's Amery Ice Shelf has drained, leaving a 6-meter (20-foot) deep depression visible from space. This event marks a significant water loss event for the region, though the specific duration of the drainage and the lake's original volume remain unquantified in the provided text.

Key points

• The Kronshtadskiy subglacial lake near East Antarctica's Amery Ice Shelf has drained, leaving a broad depression that deepened by more than 6 meters (20 feet) at its center.

Context

This finding highlights the dynamic nature of subglacial lakes in East Antarctica, where ice sheet dynamics can rapidly alter the landscape. The visible depression serves as a direct geological record of the lake's removal, providing insight into the stability of the Amery Ice Shelf and regional ice sheet behavior.

Limitations

The evidence is limited to a single observation of a 6-meter deep depression. The specific duration of the drainage event, the original volume of the lake, and the precise timing of the ice sheet's movement relative to this depression are not provided in the source material.
