The sensitivity of the Antarctic ice sheet to a changing climate: Past, present, and future
Abstract The Antarctic Ice Sheet (AIS) is out of equilibrium with the current anthropogenic‐
enhanced climate forcing. Paleoenvironmental records and ice sheet models reveal that the …

Multiscale modeling of ice deformation behavior
Understanding the flow of ice in glaciers and polar ice sheets is of increasing relevance in a
time of potentially significant climate change. The flow of ice has hitherto received relatively …

Capabilities and performance of Elmer/Ice, a new-generation ice sheet model
The Fourth IPCC Assessment Report concluded that ice sheet flow models, in their current
state, were unable to provide accurate forecast for the increase of polar ice sheet discharge …

Ice fabric in an Antarctic ice stream interpreted from seismic anisotropy
Here we present new measurements of an anisotropic ice fabric in a fast moving (377 ma−
1) ice stream in West Antarctica. We use∼ 6000 measurements of shear wave splitting …

Modeling ice‐crystal fabric as a proxy for ice‐stream stability
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 …

On the effects of anisotropic rheology on ice flow, internal structure, and the age‐depth relationship at ice divides
We use numerical modeling with a full‐system Stokes solver to elucidate the effects of
nonlinear rheology and strain‐induced anisotropy on ice flow at ice divides. We find that …

Multimaxima crystallographic fabrics (CPO) in warm, coarse-grained ice: New insights
ME Disbrow-Monz, PJ Hudleston, DJ Prior - Journal of structural geology, 2024 - Elsevier
Multimaxima crystallographic c-axis fabrics (CPOs) commonly observed in coarse-grained
ice have been interpreted in several different ways but remain enigmatic. We review …

The tertiary creep of polycrystalline ice: experimental evidence for stress-dependent levels of strain-rate enhancement
Laboratory creep deformation experiments have been conducted on initially isotropic
laboratory-made samples of polycrystalline ice. Steady-state tertiary creep rates,, were …

Peridynamic modelling of fracture in polycrystalline ice
In this study, a peridynamic material model for a polycrystalline ice is utilised to investigate
its fracture behaviour under dynamic loading condition. First, the material model was …

Strongly depth‐dependent ice fabric in a fast‐flowing Antarctic ice stream revealed with icequake observations
The crystal orientation fabric of glacier ice impacts its strength and flow. Crystal fabric is
therefore an important consideration when modeling ice flow. Here, we show that shear …
