Abstract	:	I apply a suite of seismic techniques to investigate iceberg calving at large glaciers around Greenland. Iceberg calving accounts for up to half of the Greenland Ice Sheet's annual mass loss, which makes understanding the physics of the calving process vital to gaining a clear picture of current behavior and future evolution of the Greenland Ice Sheet. However, the varied and complex modes of calving behavior at individual glaciers, paired with the challenges to data collection presented by an actively calving glacier, mean that much remains unknown about the dynamics of calving at marine-terminating glaciers. Seismic data offer a unique opportunity to study this active phenomenon, by allowing remote observation of calving events and quantification of the forces active during calving.
