The Winter Process Cruise aboard RV Kronprins Haakon conducted dedicated observations on processes that control the position and variability of the Polar Front in the northern Barents Sea and the distribution of Arctic and Atlantic water masses. The cruise addressed objectives of the work packages Physical drivers (Research Focus 1) and Technology and method development (Research Activity C). These data are created from the CTD data published by NMDC for the whole cruise (https://doi.org/10.21335/NMDC-814367946). The values have not be changed.
