Snow stable water isotopes of a surface transect at the EastGRIP deep drilling site, summer season 2017, 1 cm
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 at 11 positions with 10 m spacing in 2 depth intervals. The depth intervals are top 1 cm and top 7 cm. In addition, cumulative samples were taken from the...
