    • Atmospheric-driven state transfer of shore-fast ice in the northeastern Kara Sea 

      Divine, Dmitry; Korsnes, Reinert; Makshtas, Alexander; Godtliebsen, Fred; Svendsen, Harald (American Geophysical Union, 2005-09-21)
      Frequencies of observed occurrences of shore-fast ice in the northeastern Kara Sea for each month during 1953–1990 reveal a multimodality of shore-fast ice extent in late winter and spring. The fast ice extent exhibits ...

    • Barents Sea ice cover reflects Atlantic inflow 

      Årthun, Marius; Eldevik, Tor; Smedsrud, Lars Henrik; Skagseth, Øystein (The authors, 2011)
      The recent Arctic winter sea-ice retreat is most pronounced in the Barents Sea. Using available observations of the Atlantic inflow to the Barents Sea and results from a regional ice-ocean model we assess the role of ...

    • Benguela Niños: Observations and Modelling 

      Hansen, Elisabeth (The University of Bergen, 2004)
      A numerical ocean model for the South Atlantic was used to study the 1995 Benguela Niño in order to learn about the underlying forcing mechanisms of the phenomenon. By comparing observations and model output, it was found ...
