This award supports analyses of stable isotopes of water, dD, d18O and deuterium excess in the proposed West Antarctic Ice Sheet Divide (WAIS) deep ice core. The project will analyze a continuous and high-resolution record of stable isotope ratios (of water) for the new core. Isotope measurements provided by project collaborators will be interpreted with models constrained by measurements of the temperature-depth profile at the site provided by a companion project.
This project (http://www.nsf.gov/awardsearch/showAward.do?AwardNumber=0537661
) was terminated before analyses were completed, but work is continuing under the companion project award (http://www.nsf.gov/awardsearch/showAward.do?AwardNumber=0539232
