Abstract:
A dataset containing surface snow profiles of stable water isotopic composition (d18O, dD, d-excess). Snow profiles had a depth of 30 cm and were sampled with a 2 cm vertical resolution. Profiles were taken at 20 positions with 2 m spacing between each on six dates during the spring and summer of 2019 in northeast Greenland. In the same area, a photogrammetry structure-from-motion approach was performed to generate digital elevation models for each day (cross-ref to other PANGAEA submission). All measurements were taken at the East Greenland Ice Core Project site (EastGRIP) situated in the accumulation zone of the Greenland Ice Sheet. The snow profiles were cut in the field and stored in WhirlPaks. The samples were kept frozen and were shipped to the ISOLAB Facility at the Alfred-Wegener-Institute in Potsdam, Germany. The samples were measured with an L2140-i CRDS device from Picarro Inc. with a high-throughput vaporizer. All data were corrected for memory and instrumental drift as suggested in van Geldern and Barth (2012) using the calibration algorithm described in Münch et al. (2016). The mean measurement uncertainty for δ18O and δD derived from an independent quality control standard was 0.13 and 1.4 ‰ for samples, respectively, and 0.09 and 0.7 ‰ for all used reference waters.
