Shear dilation of subglacial till results in time-dependent sliding laws
KLP Warburton, DR Hewitt… - Proceedings of the …, 2023 - royalsocietypublishing.org
The dynamics of glacial sliding over water-saturated tills are poorly constrained and difficult
to capture realistically in large-scale models. Experiments characterize till as a plastic …

Multi-scale variations of subglacial hydro-mechanical conditions at Kongsvegen glacier, Svalbard
The flow of glaciers is largely controlled by changes at the ice–bed interface, where basal
slip and sediment deformation drive basal glacier motion. Determining subglacial conditions …

The kinematic significance of subglacial bedforms and their use in palaeo-glaciological reconstructions
Subglacial bedforms are relevant geomorphic markers for palaeo-glaciological
reconstructions. Due to the complexity of thermomechanical interactions between ice, till and …

Debris cover limits subglacial erosion and promotes till accumulation
I Delaney, LS Anderson - Geophysical Research Letters, 2022 - Wiley Online Library
Glaciers are commonly conceptualized as bodies composed of snow and ice. Yet, many
glaciers contain a substantial amount of rock, especially those abutting steep mountains …

A power-based abrasion law for use in landscape evolution models
Subglacial abrasion drives erosion for many glaciers, inundating forefields and proglacial
marine environments with glaciogenic sediments. Theoretical treatments of this process …

Subglacial hydrology modeling predicts high winter water pressure and spatially variable transmissivity at Helheim Glacier, Greenland
Water pressure beneath glaciers influences ice velocity. Subglacial hydrology models are
helpful for gaining insight into basal conditions, but models depend on unconstrained …
