Science Summary:
This project will drill and recover a new ice core from South Pole, Antarctica. The South Pole ice core will be drilled to a depth of 1500 m, providing an environmental record spanning approximately 40 kyrs. This core will be recovered using a new intermediate drill, which is under development by the U.S. Ice Drilling Design and Operations (IDDO) group in collaboration with Danish scientists. The intellectual merit of the work is that the analysis of stable isotopes, atmospheric gases, and aerosol-borne chemicals in polar ice has provided unique information about the magnitude and timing of changes in climate and climate forcing through time. The international ice core research community has articulated the goal of developing spatial arrays of ice cores across Antarctica and Greenland, allowing the reconstruction of regional patterns of climate variability in order to provide greater insight into the mechanisms driving climate change. The broader impacts of the project include obtaining the South Pole ice core will support a wide range of ice core science projects, which will contribute to the societal need for a basic understanding of climate and the capability to predict climate and ice sheet stability on long time scales. Second, the project will help train the next generation of ice core scientists by providing the opportunity for hands-on field and core processing experience for graduate students and postdoctoral researchers. A postdoctoral researcher at the University of Washington will be directly supported by this project, and many other young scientists will interact with the project through individual science proposals. Third, the project will result in the development of a new intermediate drill which will become an important resource to US ice core science community. This drill will have a light logistical footprint which will enable a wide range of ice core projects to be carried out that are not currently feasible.

Logistics Summary:
This collaborative Antarctic project between Twickler (GL LEAD 1142646, UNH), Saltzman (1142517, UC-Irvine), and Steig (1141839, UW) will test a new drill, which is under development by the U.S. Ice Drilling Design and Operations (IDDO) group in collaboration with Danish scientists that will eventually be used at South Pole. Drilling is planned at the South Pole for the 2014-2015 and 2015-2016 field seasons. Testing will take place near Summit Station, Greenland during the summer of 2014. In late-April through mid-June a team of six drillers will test the IDD at a site three miles north of Summit Station proper. An additional six participants from the research/logistics team will visit the site in mid-May to evaluate the drill’s performance.

CPS will provide transport of drilling fluid and casing via the GrIT; provision of generator support and fuel from the Summit Station inventory; ANG airlift from the U.S. for researchers, drillers, and cargo; en route user days in Kangerlussuaq and Summit Station; camp equipment from CPS inventory; engineering support, construction materials, and labor support for provision of the power system, excavation of the trench, movement of the WxPort, and setup of camp; CPS Camp Coordinator support; and, shipment for two boxes of frozen samples Summit > Kangerlussuaq > NY > NICL. IDDO will design, fabricate and test IDD capable of coring to 1500 meters. All other logistics will be organized by the researchers and paid through the grant.
