    • Dense water formation and circulation in the Barents Sea 

      Årthun, Marius; Ingvaldsen, Randi; Smedsrud, Lars Henrik; Schrum, Corinna (Peer reviewed; Journal article, 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 We present previously unpublished observations from shallow banks in the Barents Sea, which reveal large interannual ...

    • Heat in the Barents Sea: Transport, storage, and surface fluxes 

      Smedsrud, Lars Henrik; Ingvaldsen, Randi; Nilsen, Jan Even Øie; Skagseth, Øystein (Journal article, 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 (Peer reviewed; Journal article, 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 ...

    • Productivity in the Barents Sea - Response to recent climate variability 

      Dalpadado, Padmini; Arrigo, Kevin R.; Hjøllo, Solfrid Sætre; Rey, Francisco; Ingvaldsen, Randi; Sperfeld, Erik; van Dijken, Gert L.; Stige, Leif Christian; Olsen, Are; Ottersen, Geir (Peer reviewed; Journal article, 2014-05-01)
      The temporal and spatial dynamics of primary and secondary biomass/production in the Barents Sea since the late 1990s are examined using remote sensing data, observations and a coupled physical-biological model. Field ...

    • The seasonal cycle in the Atlantic transport to the Barents Sea during the years 1997–2001 

      Ingvaldsen, Randi; Asplin, Lars; Loeng, Harald (Peer reviewed; Journal article, 2004)
      The seasonal cycle in the Atlantic inflow to the Barents Sea is investigated by using 4-year long records from moored current meters, additional moorings of shorter duration, and hydrographic measurements. A higher transport ...

    • Skillful prediction of Barents Sea ice cover 

      Onarheim, Ingrid Husøy; Eldevik, Tor; Årthun, Marius; Ingvaldsen, Randi; Smedsrud, Lars Henrik (Peer reviewed; Journal article, 2015-07-08)
      A main concern of present climate change is the Arctic sea ice cover. In wintertime, its observed variability is largely carried by the Barents Sea. Here we propose and evaluate a simple quantitative and prognostic framework ...

    • Velocity field of the western entrance to the Barents Sea 

      Ingvaldsen, Randi; Asplin, Lars; Loeng, Harald (Peer reviewed; Journal article, 2004-03-13)
      By the use of 4-year long records from moored current meters between 71°30′N and 73°30′N of the western entrance to the Barents Sea, the velocity field of the Atlantic inflow is examined. The mean velocity field shows the ...
