Greenland: Quantifying Heat/Mass Structure and Fluxes through the Full Thickness of Greenland's Percolation Zone

The goal of the project is to quantify the structure, thermal state, and heat fluxes through the full thickness of the firn column across a transect spanning western Greenland's percolation zone. The project will achieve these objectives by drilling a combination of shallow and deep cores/boreholes at a series of sites between Swiss Camp and Crawford Point. Deep (up to 100 meters) boreholes will be drilled using hot water methods via with a drill that is being developed by the investigators. These deep boreholes will be augmented with a number of shallow cores to quantify density and provide access for temperature logging of the shallow firn thickness. The shallow cores will be drilled with a IDDO Hand Auger and Sidewinder.
