    Data Acquisition and Processing

    Ice was sampled along a longitudinal transect spanning 28 km on the lower Taylor Glacier. Samples were obtained with ice screws, emplanted 10cm in the ice, after chopping off a surface layer of a few cm thickness with an axe. Each sample in the data set is a mixture of ice from four screws, located within 2 m of one another. Isotope ratios were measured on a Finnegan-MAT Delta Plus XL triple collector mass spectrometer. For deuterium ratios, sample size was ten microliters, and the sample was analyzed using a hot chromium reactor interfaced with the spectrometer in dual inlet mode. For oxygen ratios, sample size was 200 microliters, and analysis used the CO2 equilibration method. For both isotope ratios, isotopic drift in the machine was corrected using multiple standards that bracketed the sample values (Aciego et al. 2007).
