At the majority of the sampling locations, 4 snow profiles in a triangle setup (one profile in the center surrounded by the others with 10m spacing) have been sampled. The common sampling setup is attached as a figure (see "Further details"). At some locations, there are less samples available or the central profile was deepened to 4m.Measurement quality statement:CRDS: Precision for δ18O of <0.1‰IC: Normative precision of <10% for anions, <20% for cations.We report quality (accuracy) issues for Ca2+, Mg2+ and K+ concentrations in the IC system.Ca2+, Mg2+ and K+ concentrations are significantly lower than those measured by other methods, especially for low concentrations (<30ppb).The exact cause of this under-recovery is still under investigation. ...
