A 58 m long azimuthally oriented ice core has been collected from the floating lateral
sinistral shear margin of the lower Priestley Glacier, Terra Nova Bay, Antarctica. 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-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 …

Ground penetrating radar (GPR) has been extensively used in glaciology to infer glacier's
ice thickness, liquid water content, water drainage pathways, and other properties. The …

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 …

Crystallographic preferred orientations (CPOs) are particularly important in controlling the
mechanical properties of glacial shear margins. Logistical and safety considerations often …

Grain growth can modify the microstructure of natural ice, including the grain size and
crystallographic preferred orientation (CPO). To understand better grain-growth processes …

Multimaxima crystallographic c-axis fabrics (CPOs) commonly observed in coarse-grained
ice have been interpreted in several different ways but remain enigmatic. We review …

We use high resolution, ground-based observations of ice displacement to investigate ice
deformation across the floating left-lateral shear margin of Priestley Glacier, Terra Nova Bay …

Creep due to ice flow is generally thought to be the main cause for the formation of
crystallographic preferred orientations (CPOs) in polycrystalline anisotropic ice. However …
