QSAR methodology for calculating impact on organisms exposed to dissolved oil in the water column - ERA Acute for water column exposed organisms - OC2020 A-030
ERA Acute uses results from an oil spill model to calculate impact from exposure to the spilled oil in the four compartments: sea surface, shoreline, water column and sea floor. The oil spill model is run in stochastic mode to combine the impact with a probablity for the impact to calculate...

Oil Spill Contingency and Response Modelling in Ice-Covered Waters
Biodegradation of Dispersed Oil in natural Seawaters from Western Greenland and a Norwegian fjord
With increasing oil exploration, production and transportation in the Arctic, predictions of the fate of spilled oil become important, including oil compound biodegradation. The use of chemical dispersants may result in increased biodegradation due to the generation of dispersions consisting of...
Toxicokinetics of Crude Oil Components in Arctic Copepods
The risk of accidental oil spills in the Arctic is on the rise due to increased shipping and oil exploration activities, making it essential to calibrate parameters for risk assessment of oil spills to Arctic conditions. The toxicokinetics of crude oil components were assessed by exposing one lipid...
Impact and restitution model - Water column. ERA Acute for water column exposed organisms
Exposure to oil components in the water column in ERA Acute can be modelled using either of two alternative options in the oil spill model OSCAR. While the option based on the Critical Body Residue (CBR) takes changing oil properties/toxicities and exposure time into account and therefore represents...
ERA Acute-Implementation of a New Method for Environmental Risk Assessment of Acute Offshore Oil Spills
Energy companies, like Statoil and TOTAL conduct Environmental Risk assessments (ERAs) as part of their risk management processes to ensure acceptable environmental risk for all operations. In some parts of the world, ERAs are required by regulators to assess risk and as a basis for evaluating risk...
Petroleum hydrocarbon and microbial community structure successions in marine oil-related aggregates associated with diatoms relevant for Arctic conditions
Oil-related aggregates (ORAs) may contribute to the fate of oil spilled offshore. However, our understanding about the impact of diatoms and associated bacteria involved in the formation of ORAs and the fate of oil compounds in these aggregates is still limited. We investigated these processes in...
