    • Combined effects of crude oil exposure and warming on eggs and larvae of an arctic forage fish 

      Giebichenstein, Julia; Teisrud, Ragnar; Laurent, Jennifer Malica; Frantzen, Marianne; Meador, James P.; Sørensen, Lisbet; Hansen, Bjørn Henrik; Reinardy, Helena C.; Laurel, Benjamin J.; Nahrgang, Jasmine (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-16)
      Climate change, along with environmental pollution, can act synergistically on an organism to amplify adverse effects of exposure. The Arctic is undergoing profound climatic change and an increase in human activity, resulting in a heightened risk of accidental oil spills. Embryos and larvae of polar cod (Boreogadus saida), a key Arctic forage fish species, were exposed to low levels of crude oil ...

    • Effects of chronic dietary petroleum exposure on reproductive development in polar cod (Boreogadus saida) 

      Bender, Morgan Lizabeth; Frantzen, Marianne; Vieweg, Ireen; Falk-Petersen, Inger-Britt; Johnsen, Helge Kreutzer; Rudolfsen, Geir; Tollefsen, Knut Erik; Dubourg, Paul; Nahrgang, Jasmine (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-04)
      Increasing human activities in the Arctic raise the risk of petroleum pollution, thus posing an elevated risk for Arctic organisms to be chronically exposed to petroleum compounds. The endocrine disrupting properties of some of these compounds (i.e. polycyclic aromatic hydrocarbons [PAHs]) present in crude oil may have negative effects on the long and energy intensive reproductive development of ...

    • Effects of mine tailings exposure on early life stages of Atlantic cod 

      Reinardy, Helena; Pedersen, Kristine Bondo; Nahrgang, Jasmine; Frantzen, Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-22)
      In Norway, mine tailings waste can be deposited by coastal submarine dispersal. Mine tailings slurry includes fine particles <10 µm with elevated levels of metals (e.g., copper, iron) from residual mineral ore. Prolonged suspension of small particles in the water column may bring them into contact with locally spawned pelagic fish eggs, including Atlantic cod, <i>Gadus morhua</i>. Newly fertilized ...

    • Effects of the sea lice bath treatment pharmaceuticals hydrogen peroxide, azamethiphos and deltamethrin on egg-carrying shrimp (Pandalus borealis) 

      Frantzen, Marianne; Bytingsvik, Jenny; Tassara, Luca; Reinardy, Helena C.; Refseth, Gro Harlaug; Watts, Ellie J.; Evenset, Anita (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-16)
      This study investigated effects of sea lice pharmaceuticals on egg-bearing deep-water shrimp (Pandalus borealis). Both mortality and sub-lethal effects (behavior, embryo development, and reproductive output) were studied for each of three pharmaceuticals alone and in different sequential combinations. The most severe effect was observed for deltamethrin where 2 h exposure to 330 times diluted treatment ...

    • Fistfighting "Super Injun". Reinscribing Native American Literature in the English Classroom 

      Frantzen, Marianne (Master thesis; Mastergradsoppgave, 2015-05-15)
      This thesis examines ways in which Native Americans are portrayed in literature by analyzing two of Sherman Alexie's short stories "This is What it Means to Say Phoenix, Arizona", and "Because my Father Always Said he Was the only Indian Who Saw Jimi Hendrix Play "The Star-Spangled Banner" at Woodstock", as well as the movies "Pocahontas" (1995) and "Smoke Signals" (Alexie, 1998). The Native ...

    • Potential effects of petroleum pollution and increasing water temperature on life-history traits in polar cod (Boreogadus saida) 

      Bender, Morgan Lizabeth; Frantzen, Marianne; Geoffroy, Maxime; Meador, James P.; Nahrgang, Jasmine (Conference object; Konferansebidrag, 2017)

    • Quantifying the consequence of applying conservative assumptions in the assessment of oil spill effects on polar cod (Boreogadus saida) populations 

      de Vries, Pepjin; Tamis, Jacqueline; Nahrgang, Jasmine; Frantzen, Marianne; Jak, Robbert; Klok, Chris; van den Heuvel-Greve, Martine J; Hemerik, Lia (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-23)
      In order to assess the potential impact from oil spills and decide the optimal response actions, prediction of population level effects of key resources is crucial. These assessments are usually based on acute toxicity data combined with precautionary assumptions because chronic data are often lacking. To better understand the consequences of applying precautionary approaches, two approaches for ...

    • Seasonal and spatial variations in biomarker baseline levels within Arctic populations of mussels (Mytilus spp.) 

      Storhaug, Ekaterina; Nahrgang, Jasmine; Pedersen, Kristine Bondo; Brooks, Steven; Petes, Laura; Bakhmet, Igor N.; Frantzen, Marianne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-28)
      Climate change and pollution resulting from human activities in the Arctic require reliable monitoring systems in sentinel species. Mytilus spp. are used as sentinel species all around the world. The use of Mytilus spp. in environmental monitoring requires knowledge about natural variations in pollution biomarkers. Seasonal variations in baseline levels of biomarkers were studied over a year in the ...
