    • Long-Term Statistics of Observed Bubble Depth Versus Modeled Wave Dissipation 

      Strand, Kjersti Opstad; Breivik, Øyvind; Pedersen, Geir; Vikebø, Frode Bendiksen; Sundby, Svein; Christensen, Kai Håkon (Journal article; Peer reviewed, 2020)
      Air bubble penetration depths are investigated with a bottom‐mounted echosounder at a seabed observatory in northern Norway. We compare a 1‐year time series of observed bubble depth against modeled and estimated turbulent ...

    • Mind the gap – Relevant design for laboratory oil exposure of fish as informed by a numerical impact assessment model 

      Frøysa, Håvard Guldbrandsen; Nepstad, Raymond; Meier, Sonnich; Donald, Carey; Sørhus, Elin; Bockwoldt, Mathias; Carroll, JoLynn; Vikebø, Frode Bendiksen (Journal article; Peer reviewed, 2023)
      Laboratory experiments provide knowledge of species-specific effects thresholds that are used to parameterize impact assessment models of oil contamination on marine ecosystems. Such experiments typically place individuals ...

    • Northeast Arctic Cod and Prey Match-Mismatch in a High-Latitude Spring-Bloom System 

      Vikebø, Frode Bendiksen; Broch, Ole Jacob; Kajiya Endo, Clarissa Akemi; Frøysa, Håvard G; Carroll, JoLynn; Juselius, Jonas; Langangen, Øystein Ole Gahr (Journal article; Peer reviewed, 2021)
      By combining an ocean model, a nutrient-phytoplankton-zooplankton-detritus-model and an individual-based model for early life stages of Northeast Arctic cod we systematically investigate food limitations and growth performance ...

    • The Northeast Greenland shelf as a potential habitat for the Northeast Arctic cod 

      Strand, Kjersti Opstad; Sundby, Svein; Albretsen, Jon; Vikebø, Frode Bendiksen (Peer reviewed; Journal article, 2017-09-26)
      Observations (1978–1991) of distributions of pelagic juvenile Northeast Arctic cod (Gadus morhua L.) show that up to 1/3 of the year class are dispersed off the continental shelf and into the deep Norwegian Sea while on ...

    • Subsurface maxima in buoyant fish eggs indicate vertical velocity shearand spatially limited spawning grounds 

      Strand, Kjersti Opstad; Vikebø, Frode Bendiksen; Sundby, Svein; Sperrevik, Ann Kristin; Breivik, Øyvind (Peer reviewed; Journal article, 2019-05)
      Observed vertical profiles of buoyant particles, in this case pelagic Northeast Arctic (NEA) cod eggs, occasionally deviate from the vertical diffusion‐buoyancy balance by displaying subsurface maxima. Here, we present a ...

    • Two decades of match-mismatch in Northeast Arctic cod – Feeding conditions and survival 

      Kajiya Endo, Clarissa Akemi; Stige, Leif Christian; Skogen, Morten D.; Ciannelli, Lorenzo; Vikebø, Frode Bendiksen (Journal article; Peer reviewed, 2022)
      The successful recruitment of Northeast Arctic (NEA) cod is thought to depend on sufficient and suitable prey for the newly hatched larvae, in particular the nauplii stages of the lipid-rich calanoid copepod species Calanus ...

    • Wind Intensity Is Key to Phytoplankton Spring Bloom Under Climate Change 

      Vikebø, Frode Bendiksen; Strand, Kjersti Opstad; Sundby, Svein (Peer reviewed; Journal article, 2019-08-30)
      The onset of the spring bloom (OSB) occurs when phytoplankton growth exceeds losses and is promoted by a transition from deep convection to a shallow mixing layer concurrent with increasing light intensities in nutrient-enriched ...
