In the designated snowpits on the MOSAic expedition, 100cm3 of snow was measured for density in the field. The same snow volume was melted for salinity measurements and sealed into glass jars onboard Polarstern. These samples were then transported to the WSL laboratory in Switzerland to analyse the stable water isotopes (δ18O and δ2H). As a result, δ18O and δ2H isotope composition was measured at the same intervals as density and salinity profiles. This dataset provides details on the date and coordinates of the snowpit event, the height of the sample in the snow profile, and the corresponding isotope composition.
