• Biodegradation in seawater of PAH and alkylphenols from produced water of a North Sea Platform 

      Lofthus, Synnøve; Almås, Inger Kjersti; Evans, Peter; Pelz, Oliver; Brakstad, Odd Gunnar (Journal article; Peer reviewed, 2018-09)
      Operational planned discharges of produced water (PW) to the marine environment from offshore oil production installations, contain low concentrations of dispersed oil compounds, like polycyclic aromatic hydrocarbons (PAH) ...
    • Biodegradation of weathered crude oil in seawater with frazil ice 

      Lofthus, Synnøve; Bakke, Ingrid; Tremblay, Julien; Greer, Charles; Brakstad, Odd Gunnar (Journal article; Peer reviewed, 2020-05)
      As ice extent in the Arctic is declining, oil and gas activities will increase, with higher risk of oil spills to the marine environment. To determine biotransformation of dispersed weathered oil in newly formed ice, oil ...
    • Modelling biodegradation of crude oil components at low temperatures 

      Nordam, Tor; Lofthus, Synnøve; Brakstad, Odd Gunnar (Others, 2020-09)
      For oil spilled at sea, the main weathering processes are evaporation, emulsification, photo-oxidation, dispersion and biodegradation. Of these, only biodegradation may completely remove hydrocarbons from the environment ...
