This award will allow the measurement of stable isotopes on the                 new deep ice core and surface snow collected at Summit, Greenland               as part of the second Greenland Ice Sheet Project (GISP II).  The               investigation will measure and interpret stable hydrogen isotope                ratios (del D values) and, in collaboration with Dr. Pieter                     Grootes, University of Washington, will measure and interpret                   deuterium excess values.  Del D and del 18 O values in ice cores                change in response to changes in paleotemperatures, the rate of                 snow accumulation, and the elevation of the ice sheet at the core               site.  Del D and del 18 values are also useful in counting annual               snow layers during the Holocene, and are thus helpful in dating                 and in determining accumulation rates during this period.                       Deuterium excess values will also be used to reconstruct                        evaporation conditions over the ocean, information needed to                    interpret delta values as well as to infer shifts in the moisture               source regions over the ocean during the past.
