Biodegradation of Dispersed Oil in natural Seawaters from Western Greenland and a Norwegian fjord
Brakstad, Odd Gunnar; Davies, Emlyn John; Ribicic, Deni; Winkler, Anika; Brönner, Ute; Netzer, Roman (Journal article; Peer reviewed, 2018-07-25)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 ... -
Biodegradation of Naturally Occurring Substances in Produced Water - Revision of data for the DREAM model
McFarlin, Kelly Marie; Brakstad, Odd Gunnar; Brönner, Ute (SINTEF Ocean reports;2018:00133, Research report, 2018-02-26)A literature review was conducted to obtain more reliable primary (biotransformation) and ultimate (biomineralization) biodegradation rates for compounds in produced water for the DREAM model, than the current biodegradation ... -
Convergence of Ensemble Simulations for Environmental Risk Assessment
Nordam, Tor; Brönner, Ute; Daae, Ragnhild Lundmark (Chapter, 2016-06)Ensemble simulations of oil fate and transport for a hypothetical oil spill, sometimes referred to as "stochastic simulations", are frequently used for environmental risk assessment related to offshore operations. In this ... -
Impact and restitution model - Water column. ERA Acute for water column exposed organisms
Brönner, Ute; Nordtug, Trond; Jonsson, Henrik; Ugland, Karl Inne (SINTEF Ocean reports;OC2018 A-035 / SINTEF F26517 / DNV GL 1IL8NGC-13, Research report, 2018-08-22)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 ... -
Numerical Integration and Interpolation in Marine Pollutant Transport Modelling
Nordam, Tor; Brönner, Ute; Skancke, Jørgen; Nepstad, Raymond; Rønningen, Petter; Alver, Morten (Chapter, 2018)Transport modelling of oil and other chemicals in the ocean relies on information on curret velocity as a function of position and time, v(x, t). These data will in many cases be supplied from an ocean circulation model, ... -
Numerical modelling of (thin) oil films - Improved behaviour and life time of thin films in the OSCAR model
Brönner, Ute; Lewis, Alun; Johansen, Øistein; Nordam, Tor (SINTEF Ocean report;OC2017 A-181, Research report, 2017-09-21)The PETRO MAKS project "Formation and behaviour of thin oil films and evaluation of response methods including HSE", in the following short "Thin oil films" has the objective to achieve new knowledge more efficient and ... -
Oil Spill Contingency and Response Modelling in Ice-Covered Waters
Nordam, Tor; Litzler, Emma; Rønningen, Petter; Aune, Joakim; Hagelien, Thomas Fjæstad; Beegle-Krause, Cynthia Juyne; Brönner, Ute (Chapter, 2018)This paper descibes several updates to SINTEFs Oil Spill Contingency and Response (OSCAR) model, which have significantly improved th emodelling of oil spills in cold and ice-covered waters. In addition to transport of ... -
Petroleum hydrocarbon and microbial community structure successions in marine oil-related aggregates associated with diatoms relevant for Arctic conditions
Netzer, Roman; Henry, Ingrid Annemarie; Ribicic, Deni; Wibberg, Daniel; Brönner, Ute; Brakstad, Odd Gunnar (Journal article; Peer reviewed, 2018-10)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 ... -
QSAR methodology for calculating impact on organisms exposed to dissolved oil in the water column - ERA Acute for water column exposed organisms
Brönner, Ute; Nordtug, Trond (SINTEF Ocean rapporter;OC2020 A-030, Research report, 2020-03-06)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 ... -
Spreading of waxy Crude Oils on calm weather
Brönner, Ute; Johansen, Øistein; Leirvik, Frode; Nordam, Tor; Sørheim, Kristin Rist (Journal article; Peer reviewed, 2018-04)The objective of this paper is to provide a simple extension of the much-used gravity spreading model for oil on calm water to account for the spreading behavior of waxy crude oils in cold waters – including the observed ... -
Toxicokinetics of Crude Oil Components in Arctic Copepods
Øverjordet, Ida Beathe; Nepstad, Raymond; Hansen, Bjørn Henrik; Jager, Tjalling; Farkas, Julia; Altin, Dag; Brönner, Ute; Nordtug, Trond (Journal article; Peer reviewed, 2018-06-13)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. ...
