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.
The Glacier Dynamics lab at UIdaho welcomes Tristan Amaral this semester. Tristan will be working on a NASA and NSF-funded project to examine the controls on calving around the Greenland Ice Sheet. He comes... READ MORE
Several new papers published this summer exemplify the diversity of our research group’s interests and methodologies. Thanks to the outstanding scientists and co-authors who led these efforts: Denis Felikson, Rebecca Jackson, and Matteo... READ MORE
It’s been a busy summer for the Glacier Dynamics group, with a number of high-profile presentations focused around glacier seismology. In June, Tim participated in back to back workshops on Environmental Seismology, then taught... READ MORE
While glacier advance is extremely rare, study of advancing glaciers offers a more complete picture of glacier dynamics and the factors that enable such advances. In Alaska, Yahtse Glacier is the fastest advancing... READ MORE
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
