    • Arbeidstakers ytringsfrihet på sosiale medier. En avveining mellom lojalitetsplikt og ytringsfrihet, særlig i form av ytringer på sosiale medier 

      Asbjørnsen, Helene (Master thesis, 2018-07-07)

    • Deconstructing Future AMOC Decline at 26.5°N 

      Asbjørnsen, Helene; Årthun, Marius (Journal article; Peer reviewed, 2023)
      The Atlantic Meridional Overturning Circulation (AMOC) is frequently used to diagnose the state of the North Atlantic circulation, but as an integrated quantity the AMOC strength does not necessarily mirror changes in the ...

    • The effect of vertical mixing on the horizontal drift of oil spills 

      Röhrs, Johannes; Dagestad, Knut-Frode; Asbjørnsen, Helene; Nordam, Tor; Skancke, Jørgen; Jones, Cathleen; Brekke, Camilla (Peer reviewed; Journal article, 2018)
      Vertical and horizontal transport mechanisms for marine oil spills are investigated using numerical model simulations. To realistically resolve the 3-D development of a spill on the ocean surface and in the water column, ...

    • Future strengthening of the Nordic Seas overturning circulation 

      Årthun, Marius; Asbjørnsen, Helene; Chafik, Léon; Johnson, Helen L.; Våge, Kjetil (Journal article; Peer reviewed, 2023)
      The overturning circulation in the Nordic Seas involves the transformation of warm Atlantic waters into cold, dense overflows. These overflow waters return to the North Atlantic and form the headwaters to the deep limb of ...

    • Mechanisms and pathways of ocean heat anomalies in the Arctic-Atlantic region 

      Asbjørnsen, Helene (Doctoral thesis, 2020-12-10)
      Along the Atlantic water pathway, from the Gulf Stream in the south to the Arctic Ocean in the north, variability in ocean heat content is pronounced on interannual to decadal time scales. Ocean heat anomalies in this ...

    • Mechanisms of Ocean Heat Anomalies in the Norwegian Sea 

      Asbjørnsen, Helene; Årthun, Marius; Skagseth, Øystein; Eldevik, Tor (Peer reviewed; Journal article, 2019-04)
      Ocean heat content in the Norwegian Sea exhibits pronounced variability on interannual to decadal time scales. These ocean heat anomalies are known to influence Arctic sea ice extent, marine ecosystems, and continental ...

    • Mechanisms underlying recent Arctic atlantification 

      Asbjørnsen, Helene; Årthun, Marius; Skagseth, Øystein; Eldevik, Tor (Journal article; Peer reviewed, 2020-06-20)
      Recent warming and reduced sea ice concentrations in the Atlantic sector of the Arctic Ocean are the main signatures of ongoing Arctic “Atlantification.” The mechanisms driving the warming trends are nevertheless still ...

    • Variable Nordic Seas Inflow Linked to Shifts in North Atlantic Circulation 

      Asbjørnsen, Helene; Johnson, Helen L.; Årthun, Marius (Journal article; Peer reviewed, 2021)
      The inflow across the Iceland-Scotland Ridge determines the amount of heat supplied to the Nordic Seas from the subpolar North Atlantic (SPNA). Consequently, variable inflow properties and volume transport at the ridge ...

    • Winter circulation anomalies in 2009/10 & 2013/14, and associated forcing mechanisms 

      Asbjørnsen, Helene (Master thesis, 2016-05-31)
      Recent cases of severe winter weather in midlatitude regions have been linked to large-scale atmospheric circulation anomalies, but the physical mechanisms driving such anomalies are poorly understood. In this study the ...
