Ice Core Paleoclimatology

Field Logistics

Field Logistics

From April 30th to June 10th, 2002 a deep drilling program was conducted on the col of Bona-Churchill in southeastern Alaska. This was the critical meteorological window when weather conditions were the best for aircraft operations and temperatures were still sufficiently cold at the col to drill the ice cores and store them for retrograde. The field operations were supported by an AS350 helicopter (photo below) that was piloted by Lambert DeGavere, under contract from ERA Aviation, and an Otter (photo below) piloted by Paul Klaus of Ultimate Thule Outfitters. VECO, under contract to NSF, provided the logistical support including air support.
