Compacted Snow Testing Methodology and Instrumentation
Snow is a complex material that is difficult to characterize especially due to its high compressibility and temperature-sensitive nonlinear viscoelasticity. Snow mechanics has been intensively investigated by avalanche and army researchers for decades. However, fewer research studies have been …

Design and analysis of penetrator probes for planetary science applications
… for air-deployment from LC-130 aircraft into snow pack on the Ross Ice Shelf, using existing polar research aircraft as the deployment method. The mission objective is to measure seismic readings and ice shelf displacement for a full year in order to improve understanding of the dynamic effect …

On mechanics and microstructure of weak snow layers
Dry-snow slab avalanches begin when a buried weak layer fails. This local damage can spread across the slope as a crack, detaching the overlying slab from the snowpack. If the slope is sufficiently steep, basal friction is overcome and the avalanche releases. Forecasting these avalanches remains …
