Collaborative Research: Stable Isotopes of Ice in the Transition and Glacial Sections of the WAIS Divide Deep Ice Core (NSF Award Number 1043092)

WAIS Divide Core 06A 68,000 years ago through 2000C.E. Isotope Data from University of Washington (Eric Steig). Data set of 0.25 to 1 meter averages of oxygen isotope data from the WAIS Divide ice core. The full data set produced by Eric Steig, Andrew Schauer, Peter Neff Spruce Schoenemann, Bradley Markle, Rebecca Teel, Beth VanDen Heuvel,Kyle Samek at the University of Washington Isolab, ( How to cite these data. 1) This full data set was published in the following paper: WAIS Divide Project Members. Precise interpolar phasing of abrupt climate change during the last ice age. Nature, in press (2015).

Nature Geoscience 6: 372-375, doi:10.1038/ngeo1778 (2013). 3) The most recent 30000 years of these data were first published in: WAIS Divide Project Members. Onset of deglacial warming in West Antarctica driven by local orbital forcing. Nature 500: 440-444, doi:10.1038/nature12376 (2013). 4) Development of the WD2014 timescale is described in: Buizert, C. et al., The WAIS-Divide deep ice core WD2014 chronology -- Part 1: Methane synchronization (68-31 ka BP) and the gas age-ice age difference. Climate of the Past, 11: 153-173, doi:10.5194/cp-11-153-2015 (2015). All isotope data (d18O) in per mil, normalized to the IAEA VSMOW/SLAP scale. See Schoenemann et al., doi:10.1002/rcm.6486 (2014), for discussion of isotope-ratio normalization methods. Precision and accuracy <0.1 and <1 per mil for d18O and dD respectively. All ages are given in years before 1950.0 C.E. (A.D.) on the WD2014 timescale.
