    • Growth and metabolism of adult polar cod (Boreogadus saida) in response to dietary crude oil 

      Nahrgang, Jasmine; Bender, Morgan Lizabeth; Meier, Sonnich; Nechev, Jordan; Berge, Jørgen; Frantzen, marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-06)
      The increasing human presence in the Arctic shelf seas, with the expansion of oil and gas industries and maritime shipping, poses a risk for Arctic marine organisms such as the key species polar cod (<i>Boreogadus saida</i>). The impact of dietary crude oil on growth and metabolism of polar cod was investigated in the early spring (March–April) when individuals are expected to be in a vulnerable ...

    • Harp seal body condition and trophic interactions with prey in Norwegian high Arctic waters in early autumn 

      Haug, Tore; Biuw, Martin; Gjøsæter, Harald; Knutsen, Tor; Lindstrøm, Ulf; MacKanzie, Kirsteen M.; Meier, Sonnich; Nilssen, Kjell Tormod (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-28)
      In September 2016, a marine ecosystem survey covered all trophic levels from phytoplankton to seals in the Arctic Ocean to the west and north of Svalbard. At the ice edge, 26 harp seals were sampled to assess whether recent environmental changes had affected their diets and body condition by comparing our current results with previous investigations conducted 2–3 decades ago in the northern Barents ...

    • 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; Tidsskriftartikkel; Peer reviewed, 2023-09-09)
      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 of species and life stages in tanks with different contaminant concentrations. Exposure concentrations are usually fixed, and the individuals experience a shock treatment being ...

    • Niches of marine mammals in the European Arctic 

      MacKenzie, Kirsteen M.; Lydersen, Christian; Haug, Tore; Routti, Heli Anna Irmeli; Aars, Jon; Andvik, Clare Margaret; Borgå, Katrine; Fisk, A.T.; Meier, Sonnich; Biuw, Martin; Lowther, Andrew; Lindstrøm, Ulf Ove; Kovacs, Kit M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-11)
      The Arctic is warming rapidly, with concomitant sea ice losses and ecosystem changes. The animals most vulnerable to Arctic food web changes are long-lived and slow-growing such as marine mammals, which may not be able to adapt rapidly enough to respond to changes in their resource bases. To determine the current extent and sources of these resource bases, we examined isotopic and trophic niches ...
