We report high resolution measurements of the stable isotope ratios of ancient ice (delta O-18, delta D) from the North Greenland Eemian deep ice core (NEEM, 77.45 degrees N, 51.06 degrees E). The record covers the period 8-130 ky b2k (y before 2000) with a temporal resolution of approximate to 0.5 and 7 y at the top and the bottom of the core respectively and contains important climate events such as the 8.2 ky event, the last glacial termination and a series of glacial stadials and interstadials. At its bottom part the record contains ice from the Eemian interglacial. Isotope ratios are calibrated on the SMOW/SLAP scale and reported on the GICC05 (Greenland Ice Core Chronology 2005) and AICC2012 (Antarctic Ice Core Chronology 2012) time scales interpolated accordingly. We also provide estimates for measurement precision and accuracy for both delta O-18 and delta D.
