We're currently investigating the erosional and ecological processes happening within these deflation patches that cover a significant portion of the local landscape - approximately 22%. The strong katabatic winds blowing off the massive Greenland Ice Sheet are responsible for stripping away fine-grained loess soil, exposing glacial till beneath. As this process continues, the patch edge gradually advances as it undercuts both soil and vegetation. Meanwhile, within these patches, a biological soil crust starts to form, effectively halting future erosion and facilitating soil recovery.
