Temperature Reconstruction at the West Antarctic Ice Sheet Divide Data DOI: https://doi.org/10.15784/600377 Cite as Cuffey, K. M. (2017) "Temperature Reconstruction at the West Antarctic Ice Sheet Divide" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/10.15784/600377. AMD - DIF Record(s) NSF-ANT05-39232_1 Abstract This dataset contains the temperature reconstruction at the West Antarctic Ice Sheet (WAIS) Divide reported by Cuffey et al. (2016) in PNAS. Five files contain 1) the primary reconstruction (Eq. 2 of that publication), combining information from borehole temperatures, deuterium isotopic content of ice, and nitrogen-15 content of trapped diatomic nitrogen gas; 2) the primary reconstruction with higher-frequency content restored; 3) the lower limit of the primary reconstruction; 4) the upper limit of the primary reconstruction; and 5) and the primary reconstruction with added perturbations.
