Geophysical Investigation Of Icy Debris Fans With Ground Penetrating Radar, Southern Alps, New Zealand, Erica May Rubino

Honors Theses

Degradation of ice caps has begun to alter alpine periglacial regions, resulting in the exposure of bedrock escarpments, and in the occurrences of mass-flow processes. These mass wasting processes include ice avalanches, rockfalls, slushflows, and icy debris flows, and can result in the development of poorly understood landforms known as icy debris fans. Icy debris fans are formed at the base of escarpments along the margins of valley glaciers. According to a 2013 study in New Zealand, fan surfaces are dominated by ice and lithic material derived from ice avalanches, which constitute >90% of mass flows annually. Depositional processes over …
