[HTML][HTML] Subglacial lake drainage detected beneath the Greenland ice sheet
The contribution of the Greenland ice sheet to sea-level rise has accelerated in recent
decades. Subglacial lake drainage events can induce an ice sheet dynamic response—a …

Potential subglacial lakes and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets
We use the Shreve hydraulic potential equation as a simplified approach to investigate
potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic …

Antarctic basal environment shaped by high-pressure flow through a subglacial river system
The stability of ice sheets and their contributions to sea level are modulated by high-
pressure water that lubricates the base of the ice, facilitating rapid flow into the ocean. In …

Evolution of the subglacial drainage system beneath the Greenland Ice Sheet revealed by tracers
Abstract Predictions of the Greenland Ice Sheet's response to climate change are limited in
part by uncertainty in the coupling between meltwater lubrication of the ice-sheet bed and …

Increased flow speed on a large East Antarctic outlet glacier caused by subglacial floods
Abstract Changes in the velocity of large outlet glaciers and ice streams in Greenland and
Antarctica are important for ice-sheet mass balance and hence sea level. Mass loss in large …

Supraglacial lakes on the Greenland ice sheet advance inland under warming climate
Supraglacial lakes (SGLs) form annually on the Greenland ice sheet, and, when they drain,
their discharge enhances ice-sheet flow by lubricating the base and potentially by warming …
