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.
