[HTML][HTML] Accelerating ice flow at the onset of the Northeast Greenland Ice Stream
Mass loss near the ice-sheet margin is evident from remote sensing as frontal retreat and

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 …

Dilation of subglacial sediment governs incipient surge motion in glaciers with deformable beds
BM Minchew, CR Meyer - Proceedings of the Royal …, 2020 - royalsocietypublishing.org
Glacier surges are quasi-periodic episodes of rapid ice flow that arise from increases in slip
rate at the ice–bed interface. The mechanisms that trigger and sustain surges are not well …

Temperate ice in the shear margins of the Antarctic Ice Sheet: Controlling processes and preliminary locations
CR Meyer, BM Minchew - Earth and Planetary Science Letters, 2018 - Elsevier
The flux of grounded ice from the Antarctic Ice Sheet (AIS) primarily occurs through narrow,
fast-flowing outlet glaciers and ice streams. Shearing generates heat in the lateral glacier …
