Abstract:
During the Polarstern cruise PS131 in July and August 2022 in the marginal ice zone in the Fram Strait and at two ice stations on fast ice (Greenland), ice core samples were obtained with a 9 cm Kovacs corer on ice stations. This dataset contains vertical density and salinity profiles obtained by cutting the core in 4 cm intervals (for the upper 40cm) and 10 cm intervals for the remaining part. The samples were weighted on the ice. Together with the known volume densities can be calculated for each sample. They were then taken to the ship for later salinity measurements (Greisinger G1410 salinometer). For most of the samples, the whole ice layer was sampled, but for some, only the upper 40 cm were measured. However, the measured total ice thickness is included in the dataset. For more information of these measurements the user is referred to Chapter 8 of the cruise report.
