The Joint Cruise 2-1 addressed objectives of the work packages Physical drivers (Research Foci 1), Human impact (Research Foci 2) and The living Barents Sea (Research Foci 3) along the Nansen Legacy transect in open water and within the sea ice. The cruise focussed on comparing the state of the physical, chemical and biological conditions in the southern and northern parts of the study area. These data are created from the CTD data published by NMDC for the whole cruise (https://doi.org/10.21335/NMDC-2085836005). The values have not be changed.
