SLGRID2 (2014) low-res
sketchfab
We are investigating erosional and ecological processes within these deflation patches that cover 22% of the local terrain in June/July 2014. Strong katabatic winds from the Greenland Ice Sheet strip away fine-grained loess soil, revealing glacial till underneath. The patch edge expands as soil and vegetation are undercut along its edges. A biological soil crust forms within patches, limiting future erosion and facilitating soil recovery.
