Drilling of shallow firn cores at Skinner Saddle and Gawn Ice Piedmont

As part of the site reconnaissance we drilled a 17m and 13m deep firn core at SKS and GIP, respectively. The drilling system was kindly provided by the Alfred Wegener Institute. The initial data set from these cores allow us to calculate annual accumulation and establish transfer functions with meteorological data to establish the quality and sensitivity of the ice.
