We're investigating the effects of erosion on these deflation patches that cover nearly a quarter of the local terrain. In June and July 2014, katabatic winds from the Greenland Ice Sheet stripped away fine-grained loess soil, revealing underlying glacial till beneath the surface. As soil and vegetation are undercut along the patch edges, those areas continue to advance outward. Meanwhile, within the patches themselves, a biological crust forms on top of the soil, blocking future erosion and facilitating recovery processes.
