Heterogeneous melting near the Thwaites Glacier grounding line
Thwaites Glacier represents 15% of the ice discharge from the West Antarctic Ice Sheet and
influences a wider catchment,–. Because it is grounded below sea level,, Thwaites Glacier is …

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 …

Ocean tide influences on the Antarctic and Greenland ice sheets
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
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 …

Sensitivity of Pine Island Glacier to observed ocean forcing
Abstract We present subannual observations (2009–2014) of a major West Antarctic glacier
(Pine Island Glacier) and the neighboring ocean. Ongoing glacier retreat and accelerated …
