This dataset contains measurements of dielectric permittivity and dielectric loss of ice core samples by impedance measurements at 50 MHz on ice stations during the Polarstern cruise PS131 in the marginal ice zone in the Fram Strait between mid-July and 6th of August 2022. Measurements were performed using the Stevens Water Monitoring Systems Hydra Probe Sensor. Ice core samples were obtained with a 9 cm corer. Then a positioning device was used to drill four 3mm holes vertically into the ice core for the device's central waveguide and outer rods. A response was recorded in one-minute intervals for several minutes. The dataset contains both mean and standard deviation of each placement. The dataset also contains temperature, salinity and density measurements (all independent of the device) of the sampled ice cores. For more information of these measurements the user is referred to Chapter 8 of the cruise report. The columns "Site" and "Floe" refer to the nomenclature used in that cruise report with the sites being relative positions on the floes as shown in Figure 3.2.3 therein.
