Snow stable water isotopes of a 1 cm deep surface transect at the EastGRIP deep drilling site, summer season 2019 ...
Snow samples were taken on a daily basis along a 100 m wind-parallel transect at the EastGRIP ice core deep drilling site. The snow was collected in the morning at 11 positions with 10 m spacing into four cumulative samples – each for one depth interval. The depth intervals are top 0.5 cm , top 1 cm...
