    • Simulating vertical turbulent dispersal with finite volumes and binned random walks 

      Høgsbro Thygesen, Uffe; Ådlandsvik, Bjørn (Journal article; Peer reviewed, 2007-10-11)
      Early life stages in fish are often modeled by individual-based models. The transport of individuals with ocean currents is addressed through particle-tracking techniques, which typically simulate vertical turbulent ...

    • Simulation of drift of capelin larvae in the Barents Sea 

      Eriksrød, Gro; Ådlandsvik, Bjørn (Fisken og havet, Research report, 1997)
      A model system consisting of a regional ocean circulation model and a particlebased larval transport model has been used to study the drift of capelin larvae in the Barents Sea. The modelled current pattern reproduces ...

    • Smittepress fra lakselus på vill laksefisk – estimert fra luselarvefelt med stor variabilitet 

      Sandvik, Anne Dagrun; Asplin, Lars; Bjørn, Pål Arne; Johnsen, Ingrid Askeland; Skardhamar, Jofrid; Myksvoll, Mari Skuggedal; Ådlandsvik, Bjørn; Skogen, Morten D. (Rapport fra havforskningen;Nr. 13 - 2017, Research report, 2017)

    • Spatial and temporal patterns in recruitment of shrimp Pandalus borealis in the Barents Sea 

      Aschan, Michaela; Ådlandsvik, Bjørn; Tjelmeland, Sigurd (ICES CM documents, Working paper, 2000)
      The shrimp spawn in autumn and the eggs are carried as out roe by the females until spring when the larvae hatch. Within a period of 2-3 months the shrimp larvae settle to the bottom. Today’s assessment and forecast of ...

    • Statistical modelling of temperature variability in the Barents Sea 

      Ottersen, Geir; Ådlandsvik, Bjørn; Loeng, Harald (ICES CM Documents;1994/S:2, Working paper, 1994)
      During the latter years an effort has been made to find out more about the relations between environmental variation and recruitment, growth, distribution and migration of fish. The rationale has to a large degree been ...

    • Toward a model-based prediction system for salmon lice infestation pressure 

      Sandvik, Anne Dagrun; Bjørn, Pål Arne; Ådlandsvik, Bjørn; Asplin, Lars; Skardhamar, Jofrid; Johnsen, Ingrid Askeland; Myksvoll, Mari Skuggedal; Skogen, Morten D. (Journal article; Peer reviewed, 2016-09-08)
      High salmon lice density is a threat to wild and farmed salmonid fish in Norway. To assess and identify areas for high salmon lice infestation pressure, continuous monitoring is necessary. The national Norwegian salmon ...

    • Utvandring av virtuell postsmolt 2018/2019 

      Johnsen, Ingrid Askeland; Sævik, Pål Næverlid; Ådlandsvik, Bjørn (Rapport fra havforskningen;2019 - 55, Research report, 2019)
      For å estimere belastninga vill atlantisk laks (Salmo salar) opplever grunna påslag av lakselus (Lepeophtheirus salmonis) frå oppdrettsanlegg i løpet av utvandringa som postsmolt, er det køyrt ein modell som fører virtuelle ...

    • Validating results from the model ROMS (Regional Ocean Modelling System), with respect to volume transports and heat fluxes in the Nordic Seas 

      Lien, Vidar S.; Budgell, W. Paul; Ådlandsvik, Bjørn; Svendsen, Einar (Fisken og havet, Research report, 2006)
      En 25 års modellsimulering med modellen ROMS (Regional Oceans Modelling System) er validert ved en kvantitativ sammenligning mellom modellresultater og observasjoner av temperatur og volumtransporter i De nordiske hav. I ...

    • Vi må overvåke livet i havet 

      Heldal, Hilde Elise; Ådlandsvik, Bjørn (Chronicle, 2011-03-22)

    • Virtuell utvandring av postsmolt 

      Johnsen, Ingrid Askeland; Ådlandsvik, Bjørn (Rapport fra havforskningen;Nr. 10 - 2017, Research report, 2017)

    • Water fluxes through the Barents Sea 

      Loeng, Harald; Ozhigin, Vladimir K.; Ådlandsvik, Bjørn (ICES CM Documents;1995/Mini:10, Working paper, 1995)
      The physical oceanographic conditions in the Barents Sea depend mainly on the variability in the Atlantic inflow from the Norwegian Sea and the inflow of Arctic water from the Kara Sea and the Arctic Ocean. The transport ...

    • Wind-driven variations in the Atlantic inflow to the Barents Sea 

      Ådlandsvik, Bjørn (ICES CM Documents;1989/C:18, Working paper, 1989)
      Results from a wind-driven homogeneous numerical current model for the Barents Sea are presented. The wind-driven fluctuations in the volume flux through the section between Fugløya and the Bear Island are computed for ...
