Observations indicate that groundwater-laden sedimentary aquifers are extensive beneath
large portions of the Greenland and Antarctic ice sheets. A reduction in the mechanical …

Although worldwide inventories of glacier area have been coordinated internationally for
several decades, a similar effort for glacier ice thicknesses was only initiated in 2013. Here …

Abstract Bedforms of Thwaites Glacier, West Antarctica both record and affect ice flow, as
shown by geophysical data and simple models. Thwaites Glacier flows across the tectonic …

Deformation of subglacial sediment during basal slip shapes the beds of many fast‐flowing
glaciers and ice streams. The resultant sediment flux impacts glacier dynamics and rates of …

Ice stream discharge responds to a balance between gravity, basal friction and lateral drag.
Appreciable viscous heating occurs in shear margins between ice streams and adjacent …

Glacier surges are quasi-periodic episodes of rapid ice flow that arise from increases in slip
rate at the ice–bed interface. The mechanisms that trigger and sustain surges are not well …

The evolution of glaciers and ice sheets depends on processes in the subglacial
environment. Shear seismicity along the ice–bed interface provides a window into these …

The hazardous impact and erosive potential of slow‐moving landslides depends on
landslide properties including velocity, size, and frequency of occurrence. However …

This study suggests that cold-ice processes may be more widespread than previously
assumed, even within temperate glacial systems. We present the first systematic mapping of …

Much of the knowledge of Antarctic Ice Sheet variations since its inception~ 34 Ma derives
from marine sediments on the continental shelf, deposited in glacimarine or sub-ice …
