Abstract: This data set contains measurements of d18Oatm (d18O of O2), d15N, dAr/N2, and dO2/N2 in gas bubbles from the WAIS Divide ice core. The time resolution is variable throughout the record but is ~100 years on average (from 65 ka to present). All measurements were made in the Noble Gas Isotope Laboratory at Scripps Institution of Oceanography (La Jolla, CA). The data set includes all replicate measurements as well as replicate-mean values and a calculation of measurement precision (pooled standard deviation). The second sheet of this data set includes fitted d18Oatm curves for the past 50 ka from both the WAIS Divide and Siple Dome Antarctic ice cores, both on the WD2014 timescale (Buizert et al., 2015). The second sheet also includes calculations of the time derivative of d18Oatm and d e LAND in both ice cores individual as well as in a composite record. Details of the entire data set and all relevant methods are provided in Seltzer et al., 2017.
