    • Acute and long-term effects from petroleum discharges on temperate and Arctic Calanus species 

      Jensen, Louise Kiel (Doctoral thesis; Doktorgradsavhandling, 2011-11-11)
      Summary Petroleum exploitation is emerging in the Arctic. In the Norwegian Arctic the southern Barents Sea is opened for development of oil and gas fields. This same area holds some of the world's largest and well managed commercial fish stocks such as Herring (Clupea harengus), Capelin (Mallotus villosus), Haddock (Melanogrammus aeglefinus), Atlantic Cod (Gadus morhua). For the interest of the ...

    • Bioaccumulation of phenanthrene and benzo[a]pyrene in Calanus finmarchicus 

      Jensen, Louise Kiel; Jæger, Iris; Honkanen, Jani O.; Caroll, JoLynn (Journal article; Tidsskriftartikkel, 2011)
      With petroleum exploration and development expanding in the Arctic (AMAP, 2007) there is a need to obtain additional information on the ecotoxicology of Arctic organisms. Here we perform 192 hr laboratory exposure experiments on the keystone Arctic zooplankton species, Calanus finmarchicus. We trace the accumulation and depuration of two polycyclic aromatic hydrocarbons (PAHs): phenanthrene and ...

    • Experimental studies of reproduction and feeding for two Arctic-dwelling Calanus species exposed to crude oil 

      Jensen, Louise Kiel; Carroll, Jolynn (Journal article; Tidsskriftartikkel; Peer reviewed, 2010-09-30)
      Copepods of the genus Calanus are keystone species in the transfer of energy from lower to higher trophic levels of the Arctic/sub-Arctic food web. We performed experimental tests on the reproduction and feeding of Calanus spp. exposed to the water-soluble fraction (WSF) of crude oil. Fecal pellet and egg production were examined for females of C. glacialis exposed to WSF (16 EPA) concentrations of ...
