  1. Antarctic Sciences Section Antarctic Glaciology Julie Palais Program Manager NSF/Office of Polar Programs

  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.

  8. West Antarctic Ice Sheet Program (WAIS) Ice Dynamics Studies of the Siple Coast Ice Streams • How will the unstable West Antarctic ice sheet affect future sea level? • How do rapid global climate changes occur? • Future sea-level rise? Annual WAIS Workshop Sept. 27-30, 2006 Pack Forest Conference Center, Washington (near Mt. Rainier)

  9. U.S.- International Trans-Antarctic Scientific Expedition (U.S.-ITASE) U.S. Antarctic Program, New Investigators workshop

  10. U.S.- International Trans-Antarctic Scientific Expedition (U.S.-ITASE) • To determine the spatial variability of Antarctic climate over the last 200+ years. • To determine the environmental variability in Antarctica over the last 200+ years. • Meteorology • Remote Sensing • Geophysics • Surface Glaciology • Ice Cores U.S. Antarctic Program, New Investigators workshop
