AMD - DIF Record(s) USAP-1745078_1 Abstract This dataset includes ~60-year resolution measurements of the Carbon-13 and Deuterium isotopic Composition of Atmospheric Methane (δ13C-CH4 and δD-CH4, respectively) of gas bubbles from the WAIS Divide Replicate Ice Core. All measurements were made at the University of Bern Ice Core Laboratory (Bern, Switzerland) using a new methane stable isotope analytical system. The data includes depth-adjacent replicate samples (separated by no more than 0.3m of depth). The data are displayed as a function of WAIS Divide Replicate Core depth and were corrected for gravitational and diffusional fractionation that occurs in the firn column according to Buizert et al., 2013. 1-sigma measurement uncertainty is also included and is determined from analytical uncertainty and uncertainties associated with diffusional and gravitational fractionation.
