The Rapid Access Ice Drill (RAID) aims to rapidly drill to deep ice (up to 3,300 meters deep), followed by the coring of ice, ice-sheet bed interface, and bedrock substrate below. The RAID drilling platform will give the scientific community access to a rich record of geologic and climatic change on a variety of timescales, from the billion-year rock record to thousand-year ice and climate histories. The main objective during the 2017-18 austral summer field season is to complete a trial of the drilling system begun last season to validate its operational readiness for science drilling.
Field Season Overview
The second Antarctic Field Trial (AFT2) will operate at a site near Minna Bluff during the 2017-18 austral summer field season. This trial will commence in late 2017 after the RAID equipment is de-winterized, followed by a short traverse of approximately three days. A reconnaissance visit to the area conducted last year determined an ideal site location lying the farthest from subglacial water of the Ross Sea with great ice thickness (approximately 600 meters). Time on site is expected to be approximately four weeks. Crew will create three boreholes in proximity to the main camp site. At the conclusion of the drill trial, the equipment will be returned to the McMurdo area and winterized on snow berms at Williams Field for storage. The team will test and evaluate the ability to tow RAID onto a site, stop, position on rig mats, and set up for drilling with minimal effort and disturbance. One participant, Ryan Bay, will test a new optical borehole logger built for RAID. His tool and a logging winch on loan from T-150 (Ice Drilling Design and Operations, IDDO) will be used.
