Abstract:  Glaciers advance in response to cooling temperatures and retreat in response to warming temperatures.  In addition to this general relationship, glaciers also respond to changes in precipitation, lapse rate, wind speed, radiation, and topography, among other factors.  To examine glacier sensitivity and infer past climate changes, I use a spatially-distributed, coupled ice-flow and mass balance model to reconstruct past glacier extents based on modern climate, topography, and dated moraines.  In this talk, I will share some of my current findings and possible future collaborations with UMaine faculty.
