Supporting Stations: McMurdo Station
Research Locations: WAIS Divide Camp
The West Antarctic Ice Sheet (WAIS) Divide is a collaboration of about 40 separate but synergistic projects funded by the NSF to collect deep ice cores from the West Antarctic Ice Sheet. Work began with construction of a field camp in 2005-06, and the first cores were recovered in 2006-07. On December 31, 2011 drillers reached the final depth goal of 3,405 meters and recovered the longest U.S. ice core to date from the polar regions. The Ice Drilling Program Office (IDPO), established in 2008, is led by Mary Albert at Dartmouth College in collaboration with the University of New Hampshire and in partnership with the University of Wisconsin-Madison. The IDPO was established to articulate and maintain long- and short-term goals and plans in conjunction with the ice coring and drilling research community, enhance communication and information exchange within the research community and to the public, and oversee the Ice Drill Design and Operations (IDDO). (IDDO is the principle supplier of ice drilling and coring equipment, support and expertise for NSF-funded research.) In addition, the IDPO convenes a science advisory board for the purpose of forming and updating a long-range science plan that articulates the direction of U.S. ice coring and drilling science and identifies the drills and drilling technology required to enable the science.
Field Season Overview:
This will be the sixth operational season for IDDO’s DISC (Deep Ice Sheet Coring) drill system at WAIS Divide. Fourteen drillers will work with Jeff Severinghaus I-476 to use the DISC Drill's replicate coring technology to collect approximately 250 meters of replicate ice core.
