Water isotopologues of near-surface polar snow from short (1-m) snow cores, extracted from the EastGRIP site on Greenland Ice Sheet during summers 2017-2019 with age-depth model ...
Four data sets of water isotopologues and their products based on a time-resolved array of 1-m snow profiles extracted from the EastGRIP site on the Greenland Ice Sheet. This data product is derived from two data sets from the same EastGRIP site (Behrens et al, 2023; Steen-Larsen et al., 2023). Snow...

| Summary: | Four data sets of water isotopologues and their products based on a time-resolved array of 1-m snow profiles extracted from the EastGRIP site on the Greenland Ice Sheet. This data product is derived from two data sets from the same EastGRIP site (Behrens et al, 2023; Steen-Larsen et al., 2023). Snow profiles were extracted during the summer field seasons of 2017, 2018, and 2019. They were extracted along a wind-aligned transect approximately 300 m long. All snow profiles were taken 1-cm resolution from 0-10 cm, and 2-cm resolution from 10-100 cm. The 1-sigma uncertainty of the d18O data is 0.11 ‰. The 1-sigma uncertainty of the dD data is 0.8 ‰. Most snow profiles are not the full 100 cm depth due to compression and loss during extraction. Each extraction date represents a time when snow cores were taken at up to six different tracks spaced 50 m apart along a line perpendicular to the prevailing (westward) wind direction. Taken together, these profiles represent a large area of the ice sheet, mitigating ... |
