A Unified Blister and Subglacial Hydrology Framework for Supraglacial Lake Drainage Events
Hanwen Zhang, Laura A. Stevens, Ian J. Hewitt +1
Subglacial blisters form due to the rapid drainage of supraglacial lakes into grounded ice sheets, and are characterised by elastic ice uplift and transient ice-velocity anomalies.…

Viscoelastic mechanics of tidally induced lake drainage in the Amery grounding zone
Hanwen Zhang, Richard F. Katz, Laura A. Stevens
Drainage of supraglacial lakes to the ice-sheet bed can occur when a hydrofracture propagates downward, driven by the weight of the water in the lake. For supraglacial lakes in the…
