Glacier Change of the American West
We are evaluating the glacier change in the American West since the early scientific explorations in the late 1800s. We are interested in the spatial and temporal variations in the change and the climatic processes that cause the change. An initial part of this effort was to locate all the glaciers and permanent snowfields in the West, then construct a photographic library depicting glacier extent over time.

McMurdo Dry Valleys, Antarctica
Patterns of Human Activity in the McMurdo Dry Valleys
Humans have been visiting the McMurdo Dry Valleys each summer since the 1950s. Yet the impact of this activity on its pristine environment is unknown. As a first step towards understanding the impact we are creating a digital archive of photographs, supported by archival records of visits, to document the history of human activity throughout the Valleys. The archive will be made available on the world-wide-web for use by scientists, historians, and environmental managers.
Landscape Change of the McMurdo Dry Valleys
The landscape of the McMurdo Dry Valleys (MDV) has been undergoing dramatic changes over the past decade. A sediment-covered glacier has deflated tens of meters and a river in Garwood Valley has incised 3 m through subsurface ice. To document the large and small changes across the valleys we survey the valleys with an airborne LiDAR ( 10cm vertical resolution), and compare the elevations to an earlier LiDAR survey completed in 2001. We predict that the changes are only found where massive subsurface ice is located and these regions are the most vulnerable to future climate warming.
Community Dynamics of Cryoconite Holes
Cryoconite holes are water-filled holes that develop on glacial surfaces as a result of the deposition of low albedo material. The holes provide a habitat for well-defined microbial communities featuring a complex array of primary producers and consumers. These unique systems offer an opportunity to test fundamental questions about microbial community assembly and its effects on biodiversity and ecosystem function in a real-world, contained ecosystem.
