The Glacier Dynamics Group at the University of Idaho reveals the factors controlling the motion and rapid mass loss of glaciers and ice sheets. Our approach to research is fundamentally interdisciplinary. We draw on seismology and other geophysical techniques to understand glacier dynamics, including iceberg calving, water flow through glaciers, dynamic thinning, and the ice flow response to variable glacier hydrology. Through theory and numerical analysis, we test explanations for our glaciological observations. This work is motivated by the need to understand rapid glacier change, its impact on sea level, and on landscape change.
Specifically, our research interests and expertise include:
- glacier dynamics (the factors that make a glacier speed up or slow down, advance or retreat),
- the generation and transmission of seismic waves,
- iceberg calving and submarine melt at the fronts of tidewater glaciers,
- water flow through and beneath glaciers, and
- processes that act on and shape the earth’s surface.
The Glacier Dynamics Group is led by Dr. Timothy Bartholomaus in Moscow, ID. Dr. Bartholomaus is a glaciologist, geophysicist, educator and Assistant Professor. He was formerly a Research Associate and Postdoctoral Fellow at the University of Texas Institute for Geophysics, in Austin, TX. He received a Ph.D. in Geophysics from the University of Alaska in Fairbanks in December 2013, completed a master’s degree at the University of Colorado Boulder, and a bachelor’s degree at Dartmouth College.
Last week, I visited the Boise State Geosciences department to give a seminar on the use of seismology to understand subglacial water flow and sediment transport. I reviewed two of my recent papers,... READ MORE
I’m just back from Taku Glacier, Alaska, where UI grad student Margot Vore, UT-Austin grad student Taylor Borgfeldt, and I retrieved new seismic data from a network set up on and around the glacier.... READ MORE
I’m excited to welcome Margot Vore to my glacier dynamics group at UI. Margot will be working to better understand the flow of water through and under glaciers, through the analysis of seismic... READ MORE
This fall, I’ve moved to the University of Idaho to begin work as an Assistant Professor and expand my lab group. I’ve begun working with a graduate student who will work with glaciohydraulic... READ MORE
