    • Extent and ecological importance of escape through spawning in sea-cages for Atlantic cod 

      Uglem, Ingebrigt; Knutsen, Øyvind; Kjesbu, Olav Sigurd; Hansen, Øyvind J; Mork, Jarle; Bjørn, Pål Arne; Varne, Rebekka; Nilsen, Rune; Ellingsen, Ingrid H.; Dempster, Timothy David (Journal article; Peer reviewed, 2012)
      The culture of certain fish species to sizes at which they can reproduce has led to the escape of fertilised eggs or ‘escape through spawning’. To investigate the extent and ecological importance of spawning in sea-cages ...

      Rapporten beskriver planlegging og gjennomføringen av en tenkt forleveranse til ACE sitt oppdrettsanlegg på Tristein. Hensikten var å vise hvordan teknologi og beslutningsstøttesystem, som er videreutviklet i prosjektet, ...

    • Information-driven robotic sampling in the coastal ocean 

      Fossum, Trygve Olav; Eidsvik, Jo; Ellingsen, Ingrid H.; Alver, Morten; Fragoso, Glaucia Moreira; Johnsen, Geir; mendes, renato; Ludvigsen, Martin; Rajan, Kanna (Journal article; Peer reviewed, 2018)
      Efficient sampling of coastal ocean processes, especially mechanisms such as upwelling and internal waves and their influence on primary production, is critical for understanding our changing oceans. Coupling robotic ...

    • Innsamling og sammenstilling av relevant kunnskap om Sognefjorden 

      Solbakken, Roar; Henriksen, Kristian; Reitan, Kjell Inge; Arff, Johanne; Ellingsen, Ingrid H.; Hindar, Kjetil; Fiske, Peder; Robertsen, Grethe; Finstad, Bengt; Aas, Øystein; Johnsen, Bjørn Ove (Research report, 2011)
      Rapporten er utarbeidet av SINTEF Fiskeri og havbruk i samarbeid med Norsk institutt for naturforskning. Rapporten har kartlagt status og kunnskapshull relatert tit Sognefjorden på områdene: • Akvakultur • Anadrom laksefisk ...

    • Middle to late Holocene paleoproductivity reconstructionsfor the western Barents Sea: a model-data comparison 

      Pathirana, Irene Dorothea; Knies, Jochen; Felix, Maarten; Mann, U.; Ellingsen, Ingrid H. (Journal article; Peer reviewed, 2015)
      In this study we focus on late Holocene primary productivity (PP) variability in the western Barents Sea and its response to variable sea ice coverage by combining PP reconstructed from several sediment cores with ...

    • Modelling the cultivation and bioremediation potential of the kelp Saccharina latissima in close proximity to an exposed salmon farm in Norway 

      Broch, Ole Jacob; Ellingsen, Ingrid H.; Forbord, Silje; Wang, Xinxin; Volent, Zsolt; Alver, Morten; Handå, Aleksander; Andresen, Kjersti; Slagstad, Dag; Reitan, Kjell Inge; Olsen, Yngvar; Skjermo, Jorunn (Journal article; Peer reviewed, 2013)
      A 3-dimensional hydrodynamic−ecological model system (SINMOD) was used to estimate the full-scale cultivation potential of the brown alga Saccharina latissima in integrated multi-trophic aquaculture (IMTA) with Atlantic ...

    • Nutrient fluxes in the Arctic in the present climate regime 

      Ellingsen, Ingrid H.; Broch, Ole Jacob; Slagstad, Dag (Research report, 2014)
      The Arctic Ocean (AO) will likely become ice-free in summer within the next two decades. This will change light conditions for primary production. Parts of the AO where primary production is presently light limited will ...

    • Physical controls on phytoplankton size structure, photophysiology and suspended particles in a Norwegian biological hotspot 

      Fragoso, Glaucia Moreira; Davies, Emlyn John; Ellingsen, Ingrid H.; Chauton, Matilde Skogen; Fossum, Trygve Olav; Ludvigsen, Martin; Steinhovden, Kristine; Rajan, Kanna; Johnsen, Geir (Peer reviewed; Journal article, 2019)
      The impact of the physical environment and phytoplankton size on particle types (zooplankton, biogenic matter or phytodetritus) in the water column is poorly understood. Here, we investigate how hydrography (e.g. water ...

    • Phytoplankton community succession and dynamics using optical approaches 

      Fragoso, Glaucia Moreira; Johnsen, Geir; Chauton, Matilde Skogen; Cottier, Finlo Robert; Ellingsen, Ingrid H. (Peer reviewed; Journal article, 2020)
      The phytoplankton in coastal regions are responding to constant environmental changes, thus the use of proxies derived from in situ frequent time-series observations and validated from traditional microscopic or pigment ...

    • Toward adaptive robotic sampling of phytoplankton in the coastal ocean 

      Fossum, Trygve Olav; Fragoso, Glaucia Moreira; Davies, Emlyn John; Ullgren, Jenny; Mendes, Renato; Johnsen, Geir; Ellingsen, Ingrid H.; Eidsvik, Jo; Ludvigsen, Martin; Rajan, Kanna (Journal article; Peer reviewed, 2019)
      Currents, wind, bathymetry, and freshwater runoff are some of the factors that make coastal waters heterogeneous, patchy, and scientifically interesting—where it is challenging to resolve the spatiotemporal variation within ...
