At the International Union of Geodesy and Geophysics meeting in Montreal, Canada, Bartholomaus co-convened and presented during a symposium on Glacier Seismology. The well-attended symposium featured talks from authors around the world on topics as diverse as ice shelves, basal sliding, and avalanches. Bartholomaus presented his most recent work on the use of seismology to reveal the workings of the subglacial hydrologic system of Lemon Creek Glacier, Alaska.
