Heterogeneous melting near the Thwaites Glacier grounding line

BE Schmidt, P Washam, PED Davis, KW Nicholls… - Nature, 2023 - nature.com
Thwaites Glacier represents 15% of the ice discharge from the West Antarctic Ice Sheet and

Antarctic basal environment shaped by high-pressure flow through a subglacial river system

CF Dow, N Ross, H Jeofry, K Siu, MJ Siegert - Nature Geoscience, 2022 - nature.com
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 …

Ocean tide influences on the Antarctic and Greenland ice sheets

L Padman, MR Siegfried, HA Fricker - Reviews of Geophysics, 2018 - Wiley Online Library
Ocean tides are the main source of high‐frequency variability in the vertical and horizontal
motion of ice sheets near their marine margins. Floating ice shelves, which occupy about …

Impacts of warm water on Antarctic ice shelf stability through basal channel formation

KE Alley, TA Scambos, MR Siegfried, HA Fricker - Nature Geoscience, 2016 - nature.com
Antarctica's ice shelves provide resistance to the flow of grounded ice towards the ocean. If
this resistance is decreased as a result of ice shelf thinning or disintegration, acceleration of …
