  • 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 ...
  • Dense water formation and circulation in the Barents Sea 

    Årthun, Marius; Ingvaldsen, Randi; Smedsrud, Lars Henrik; Schrum, Corinna (Elsevier, 2011)
    Dense water masses from Arctic shelf seas are an important part of the Arctic thermohaline system. We present previously unpublished observations from shallow banks in the Barents Sea, which reveal large interannual ...
  • Frazil ice formation in ice shelf water plume 

    Smedsrud, Lars Henrik; Jenkins, Adrian (American Geophysical Union, 2004-03-17)
    We present a model for the growth of frazil ice crystals and their accumulation as marine ice at the base of Antarctic ice shelves. The model describes the flow of buoyant water upward along the ice shelf base and includes ...
  • Heat in the Barents Sea: Transport, storage, and surface fluxes 

    Smedsrud, Lars Henrik; Ingvaldsen, Randi; Nilsen, Jan Even Øie; Skagseth, Øystein (Copernicus Publications, 2010-01-11)
    A column model is set up for the Barents Sea to explore sensitivity of surface fluxes and heat storage from varying ocean heat transport. Mean monthly ocean transport and atmospheric forcing are synthesised and force the ...
  • Loss of sea ice during winter north of Svalbard 

    Onarheim, Ingrid Husøy; Smedsrud, Lars Henrik; Ingvaldsen, Randi; Nilsen, Frank (International Meteorological Institute, Stockholm University, 2014-06-05)
    Sea ice loss in the Arctic Ocean has up to now been strongest during summer. In contrast, the sea ice concentration north of Svalbard has experienced a larger decline during winter since 1979. The trend in winter ice area ...
  • Modeling ocean processes below Fimbulisen, Antarctica 

    Smedsrud, Lars Henrik; Jenkins, Adrian; Holland, David M.; Nøst, Ole A. (American Geophysical Union, 2006-01-18)
    Model simulations of circulation and melting beneath Fimbulisen, Antarctica, obtained using an isopycnic coordinate ocean model, are presented. Model results compare well with available observations of currents and hydrography ...
  • Recent and future changes of the Arctic sea-ice cover 

    Smedsrud, Lars Henrik; Sorteberg, Asgeir; Kloster, Kjell (American Geophysical Union, 2008)
    The present and future state of the Arctic sea ice cover is explored using new observations and a coupled one dimensional air–sea–ice model. Updated satellite observations of Fram Strait ice-area export show an increase ...
  • Uncertainties in Arctic sea ice thickness and volume: new estimates and implications for trends 

    Zygmuntowska, Marta; Rampal, Pierre; Ivanova, Natalia; Smedsrud, Lars Henrik (Copernicus Publications on behalf of the European Geosciences Union, 2014-04-22)
    Sea ice volume has decreased in the last decades, evoked by changes in sea ice area and thickness. Estimates of sea ice area and thickness rely on a number of geophysical parameters which introduce large uncertainties. ...
