Supporting Stations: McMurdo Station
Research Locations: WAIS Divide Camp
WAIS Divide is a collaboration of about 40 separate but synergistic projects funded by NSF to collect deep ice cores from the West Antarctic Ice Sheet (WAIS). 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. Other deploying projects this year are the Science Coordination Office (SCO, Kendrick Taylor) I-477 and and Jeff Severinghaus I-476-M. IDDO (Ice Drill Design and Operations) was established by NSF in 2008 to coordinate long- and short-term planning in collaboration with the US ice science community. IDDO is the principle supplier of ice drilling and coring equipment, support and expertise for NSF-funded research.
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.
