  • Baroclinic Instability in the West Spitsbergen Current 

    Teigen, Sigurd Henrik; Nilsen, Frank; Skogseth, Ragnheid; Gjevik, Bjørn; Beszczynska-Möller, Agnieszka (2011-07-15)
    Baroclinic instability in the West Spitsbergen Current is investigated, based on data from an array of current meter moorings along 78.83oN, across the deeper (1000-2400 m) section of the continental slope west of Svalbard. ...
  • Barotropic instability in the West Spitsbergen Current 

    Teigen, Sigurd Henrik; Nilsen, Frank; Gjevik, Bjørn (American Geophysical Union, 2010-07-24)
    Barotropic instability in the shoreward branch of the West Spitsbergen Current is investigated on the basis of data from an array of current meter moorings along 78.83°N, across the upper continental slope and shelf break ...
  • 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 ...
  • Warming of Atlantic Water in two west Spitsbergen fjords over the last century (1912-2009) 

    Pavlov, Alexey K.; Tverberg, Vigdis; Ivanov, Boris; Nilsen, Frank; Falk-Petersen, Stig; Granskog, Mats A. (Co-Action PublishingNorwegian Polar Institute, 2013-05-06)
    The recently observed warming of west Spitsbergen fjords has led to anomalous sea-ice conditions and has implications for the marine ecosystem. We investigated long-term trends of maximum temperature of Atlantic Water (AW) ...
  • Water mass modification in an Arctic fjord through cross-shelf exchange: The seasonal hydrography of Kongsfjorden, Svalbard 

    Cottier, Finlo; Tverberg, Vigdis; Inall, Mark; Svendsen, Harald; Nilsen, Frank; Griffiths, Colin (American Geophysical Union, 2005-12-08)
    Kongsfjorden and the West Spitsbergen Shelf is a region whose seasonal hydrography is dominated by the balance of Atlantic Water, Arctic waters, and glacial melt. Regional seasonality and the cross-shelf exchange processes ...
