IPSCARP22 (2014) low-res

We're studying the erosional and ecological processes happening on these deflation patches that cover 22% of this local landscape in June/July 2014. Katabatic winds blowing off the Greenland Ice Sheet are removing fine-grained loess soil, exposing glacial till underneath. As a result, the patch edge keeps advancing as it's undercut by erosion and loss of vegetation. Inside these patches, a biological soil crust is forming, which hinders future erosion and aids in soil recovery. People involved include Ruth Heindel from Earth Sciences at Dartmouth, Ross Virginia from Arctic Studies and Environmental Studies at Dartmouth, Jonathan Chipman from Geography and Earth Sciences at Dartmouth, Becca Novello, and Phoebe Racine. Sources of information can be found on http://sites.dartmouth.edu/rheindel. A research article titled "The Spatial Distribution and Ecological Impacts of Aeolian Soil Erosion in Kangerlussuaq, West Greenland" was published by Heindel, R, Chipman, J, Virginia, R in 2015 in Ann. Assoc. Am. Geogr., pages 875-890.
