  2. Antarctic Glaciology Program • Paleoclimate from ice cores (WAISCORES, ITASE) • Ice dynamics and modeling (WAIS) • Snow/Atmosphere/Ice interactions (ITASE) • Glacial Geology ( Dry Valleys, Antarctic Peninsula) • Other (Remote Sensing, Iceberg Studies)

  3. Paleoclimate from Ice Cores • Taylor Dome Ice Core • Vostok Ice Core • Siple Dome Ice Core • Upcoming WAIS Divide Project • Byrd Ice Core • Misc. other cores (e.g. South Pole) • Shallow cores from ITASE traverses

  4. Facilities/Support Services • National Ice Core Laboratory (NICL)* • NICL-Science Management Office (NICL-SMO) • Antarctic Glaciological Data Center (AGDC) • Ice Core Drilling Service (ICDS) • * NSF-USGS Cooperative Agreement Located at the Denver Federal Center

  5. Ice Core Drilling Services (ICDS)University of Wisconsin-Madison (formerly PICO) • Design, fabrication and operation of ice drilling equipment in both polar regions and high altitude ice caps. • Includes electro-mechanical ice core drills, hot water drills for deep access holes, shot holes for seismic sounding and sub-ice sampling. • Notify relevant NSF program manager when you are requesting ice coring support.
