文摘
- •
A first look inside a dynamic hydrologic network beneath the Whillans Ice Plain.
- •
No evidence of energetic flow within the subglacial drainage network.
- •
Sediment on the lake floor consists of till deposited when the ice stream grounds.
- •
Fabrics within the till suggest shallow deformation of the Whillans Ice Plain.
- •
Low sediment fluxes to the grounding zone are unlikely to stabilize the ice stream.
