The dynamic mass loss of ice sheets constitutes one of the biggest uncertainties in
projections of ice-sheet evolution. One central, understudied aspect of ice flow is how the …

The crystal structure within an ice sheet evolves in response to deformation; hence ice‐
crystal fabric records ice‐flow history. However, the complexity of crystal‐fabric evolution …

Ice at depth in ice-stream shear margins is thought to commonly be temperate, with
interstitial meltwater that softens ice. Models that include this softening extrapolate results of …

Abstract High-resolution LiDAR (Light detection and Ranging)-based digital elevation
models (DEM) have greatly improved the mapping of glacial landforms and revealed new …

Ice-crystal fabric can induce mechanical anisotropy that significantly affects flow, but ice-flow
models generally do not include fabric development or its effect upon flow. Here, we …

Strain weakening leads to the formation of high‐strain shear zones and strongly influences
terrestrial ice discharge. In glacial flow models, strain weakening is assumed to arise from …

Rapid retreat of Antarctic ice shelves in a warmer climate remains challenging to predict,
contributing to uncertainties in projections of sea level rise. The collapse of the Larsen B Ice …

Glacier flow modulates sea level and is governed largely by the viscous deformation of ice.
Multiple molecular-scale mechanisms facilitate viscous deformation, but it remains unclear …

To better constrain meltwater transport and ice viscosity in temperate glaciers, particularly in
ice stream shear margins, we use a custom permeameter to study the untested model …

Results of ice-stream models that treat temperate ice deformation as a two-phase flow are
sensitive to the ice permeability. We have constructed and begun using a custom, falling …
