The U.S. ice core research community is drilling a new deep ice core near the main ice divide of the West Antarctic Ice Sheet (WAIS). The WAIS Divide deep core will be the longest ice core obtained in West Antarctica, and likely the highest-resolution core obtainable in Antarctica that reaches through the last glacial period. In collaboration with Jim White, SIL INSTAAR, University of Colorado we are producing a continuous record of stable isotopes of water (δ18O, δD and Δ17O) on the core. Stable isotopes of water are the cornerstone measurement on ice cores, providing information on temperature variability and change through hundreds of thousands of years. More information may be found at the WAIS Divide Project web site.
