Rock glacier occurrence in Godthåbsfjord
The Greenlandic Research Council
The occurrence of rock glaciers requires both a certain climate and terrain. In Greenland, studies of rock glaciers have been focused on the Disko bay, and the southern range margin of rock glaciers has been suggested to ca 66°N. Recently, we found evidence of a potentially active rock glacier near Nuuk, which would be around 250 km further south than previously suggested.
In this pilot study we will (I) confirm or reject current rock glacier occurrence in the Godthåbsfjord area with innovative methods, (II) study their dynamic regime and (III) investigate the climatic boundary conditions necessary for rock glacier occurrence in the Sub-Arctic.
