Investigating Volcanic and Glacial Processes Using Microseismicity
… glacial sliding; and surface icequakes caused by crevassing, to see whether or not the crevasses observed are induced by hydrofracture. I use a combination of seismic observations and simple physical models to investigate these fundamental geophysical processes. Understanding the magmatic plumbing …

Reconstructing the Surge History and Dynamics of Fisher Glacier, Yukon, 1948-2022
… an advanced terminus position, intense surface crevassing, and high point velocities suggest that a surge had recently terminated, corroborating a previous report of a surge occurring around 1970. This was followed by a 40-year quiescent phase from ~1973-2013 during which the terminus underwent …

Constraining calving dynamics of marine-terminating glaciers: Developing 4D data of Store Glacier, Greenland, from repeat UAV photography
… was created, permitting detailed analysis of crevassing and calving processes over a 5-day period at a sub-daily temporal scale. Maps of the crevasses across the glacier front for each survey were produced through Gaussian blurring of the DEMs, and show a clear progression of the fractures …

Interpretation of coarsening upwards hemicycles in the Upper Paleozoic rocks of South-central West Virginia
… shifting of subdeltaic lobes initiated by crevassing in the levees. The cyclothems within the alluvial Monongahela-Dunkard (where meandering channel deposits are infrequent), is probably due to successive superposition of flood basin muds by levee-splay assemblages and lenticular, single or …
