Abstract:
The data set presents results of 27 snow and ice thickness surveys along walked transects from five Nansen Legacy cruises conducted during 2018-2022 with the Norwegian ice-going research vessel Kronprins Haakon (KPH) to the northern Barents Sea, area north of Svalbard and further into the central Arctic, namely Nansen and Amundsen basins. Data on snow thickness along the track were collected with a SnowHydro LLC Magnaprobe (MP), a semiautomated GPS snow probe. Total (ice and snow thickness) were measured with a Geonics EM31 or Geophex GEM2 multifrequency electromagnetic sounder (GEM2). For accurate positioning various GPS receivers were used. These were used to calculate along the track sea ice thickness variability. The data are representative of local ice and snow thickness variations in the area of sea ice stations.
