Mass loss near the ice-sheet margin is evident from remote sensing as frontal retreat and increases in ice velocities. Velocities in …

We compare different ways the bulk flow nonlinearity of glacier ice can be captured in an orthotropic rheology. Specifically, we …

We introduce a transfer matrix model for radio-wave propagation through layered anisotropic ice that permits an arbitrary dielectric …

We investigate the errors caused by neglecting the crystal-orientation fabric when inferring the basal friction coefficient field, and …

The crystal structure within an ice sheet evolves in response to deformation; hence ice- crystal fabric records ice-flow history. …

The area near Dome C, East Antarctica, is thought to be one of the most promising targets for recovering a continuous ice-core record …

Bulk directional enhancement factors are determined for axisymmetric (girdle and single-maximum) orientation fabrics using a …

Despite widespread use of radio-echo sounding (RES) in glaciology and broad distribution of processed radar products, the glaciological …

The South Pole Ice Core (SPICEcore), which spans the past 54 300 years, was drilled far from an ice divide such that ice recovered at …

Ice streams are bounded by abrupt transitions in speed called shear margins. Some shear margins are fixed by subglacial topography, but …

Smith, Pope, and Kohler Glaciers and the corresponding Crosson and Dotson Ice Shelves have undergone speedup, thinning, and rapid …

The South Pole Ice Core (SPICEcore) was drilled at least 180 km from an ice‐flow divide. Thus, the annual‐equivalent layer thicknesses …

Crosson and Dotson ice shelves are two of the most rapidly changing outlets in West Antarctica, displaying both significant thinning …

A firn aquifer in the Helheim Glacier catchment of Southeast Greenland lies directly upstream of a crevasse field. Previous …

Brilliant animal colors often are produced from light interacting with intricate nano-morphologies present in biological materials such …
