Biodegradation of weathered crude oil in seawater with frazil ice
Lofthus, Synnøve; Bakke, Ingrid; Tremblay, Julien; Greer, Charles; Brakstad, Odd Gunnar (Peer reviewed; Journal article, 2020)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 ... -
The effects of temperature and ice on biodegradation of crude oil
Lofthus, Synnøve (Doctoral theses at NTNU;2021:46, Doctoral thesis, 2021)Summary of thesis: This thesis investigates the effect of seawater temperature and presence of ice on biodegradation of oil. The work was done as a part of the project “Fate, behaviour and response to oil drifting into ... -
Modelling biodegradation of crude oil components at low temperatures
Nordam, Tor; Lofthus, Synnøve; Brakstad, Odd Gunnar (Journal article; Peer reviewed, 2020)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 ... -
Temperature Effects on Biodegradation of Dispersed Crude Oil: Degradation Rates and Microbial Communities Associated with Degradation of Oil Droplets
Lofthus, Synnøve (Master thesis, 2014)Depending on the weather- and sea conditions, oil spilled at sea may disperse into the water column. Dispersion of oil promotes biodegradation of oil hydrocarbons (HCs) due to an increased surface-to-volume ratio. In this ...
