Science Summary:
Understanding the flow of water through the body of a glacier or ice sheet is important, because the spatial distribution of water and the rate of infiltration to the glacier bottom is one control on water storage and pressure, glacier sliding and surging. According to the prevailing hypothesis, this water flow takes place in a network of tubular conduits. The prevailing view of englacial water flow through tubular conduits is supported by observations of caves on the margins of glaciers and explorations into moulins (a vertical shaft in a glacier). But whether such features are unique to the margin and to moulins is unclear. Project researchers will use a borehole instrument to monitor the subglacial pathways using a video-camera system developed by NASA/JPL, linked with a GPS system through an open Moulin.

Logistics Summary:
Researchers on this NASA project plan a one-week field campaign to investigate several moulins on the Jakobshavn Glacier. In mid-August, 2006, a team of 4 will travel to Kangerlussuaq via the Air National Guard. From Kangerlussuaq the team will fly commerically to Ilulissat and put-in to their first site, west of Swiss camp, via helicopter. They will camp on-site for one night before moving on to the next moulin. After a second overnight, the helicopter will pull them out. In 2007, researchers will again investigate moulins on the Jakobshavn Glacier, spending about one week in Greenland in mid-to-late August. Using helicopter support, the team of five will take day trips from Ilulissat to sites where seismic instruments are placed; they will conduct maintenance and download data. After choosing a moulin site via aerial reconnaissance, the team will spend about two days camping nearby to photograph and measure the moulin. When the field work is completed, the team will return to Ilulissat via helicopter before flying onward. In 2008, researchers will return to the Jakobshavn Glacier for similar work as in 2007. The NASA program officer, Dr. Seelye Martin, will accompany the team in the field. In early August 2009, a team of 4 will travel to Kangerlussuaq via the Air National Guard, and then to Ilulissat via commercial air. They will then travel via helicopter day trip from Ilulissat to a moulin site west of Swiss Camp to service instruments and download data; when finished, the helicopter will drop them off at Swiss Camp. There, they will work on camp infrastructure improvements for several weeks before being picked up and moved to a second moulin site via helicopter. At the second moulin, they will be joined by two more field team members. The group of six will work at the moulin for 3-4 days before departing via helicopter to Ilulissat, over the course of two days. While 3 of the team will return to Kangerlussuaq and depart the island, 3 others will remain in Ilulissat for about two days, then fly from Kangerlussuaq to Nuuk to attend a science conference (Arrangements associated with the conference have been made by the researchers). After the conference, all researchers will depart Greenland.

CPS will provide helicopter support; food and lodging in Kangerlussuaq; commercial air travel to/from Ilulissat and lodging while there; cargo shipment; and camping, communications and safety gear. NSF will recoup these costs via interagency funds transfer with NASA. Arrangements associated with the 2009 conference in Nuuk will be made by the researchers.
