TOWNGRID2 (2014) low-res 3D Model
Aeolian soil erosion, Kangerlussuaq, West Greenland
We are researching erosional and ecological processes in these deflation patches, which cover 22% of the local landscape. Katabatic winds off the Greenland Ice Sheet remove fine-grained loess soil, exposing glacial till. The patch edge advances as soil and vegetation are undercut. Within patches, a biological soil crust forms, hindering future erosion and aiding soil recovery.
