Assessment of Hydrocarbon Degradation Potential in Microbial Communities in Arctic Sea Ice
(Peer reviewed; Journal article, 2022)The anthropogenic release of oil hydrocarbons into the cold marine environment is an increasing concern due to the elevated usage of sea routes and the exploration of new oil drilling sites in Arctic areas. The aim of this ... -
Biodegradation of weathered crude oil in seawater with frazil ice
(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 ... -
Breidablikk – Weathering properties and behaviour at sea - In relation to oil spill response
(SINTEF Ocean rapporter;2023:00459 A, Research report, 2023-04-17)A standardized bench-scale weathering and dispersibility study has been conducted on Breidablikk crude oil at 5 and 13 °C. The dispersibility testing on Breidablikk was included to estimate the viscosity limits and time ... -
Crude oil migration in sea-ice: Laboratory studies of constraints on oil mobilization and seasonal evolution
(Journal article; Peer reviewed, 2019)Rising Arctic maritime activities and hydrocarbon development increase the risk of an oil spill in and under Arctic sea-ice. Oil spilled under growing sea ice would be encapsulated within the ice cover. During spring and ... -
Effect of Oil Pollution and Ice Formation on Microbial Community of Seawater from Ofotfjorden, Norway
(Chapter, 2018)Oil spill in ice-covered waters can become entrapped in sea ice and may be subjected to biodegradation by sea ice microorganisms. The extent of the hydrocarbon biodegradation, and microorganisms involved in such process ... -
Microbial Community Dynamics during Biodegradation of Crude Oil and Its Response to Biostimulation in Svalbard Seawater at Low Temperature
(Peer reviewed; Journal article, 2021)The development of oil exploration activities and an increase in shipping in Arctic areas have increased the risk of oil spills in this cold marine environment. The objective of this experimental study was to assess the ... -
No observed developmental effects in early life stages of capelin (Mallotus villosus) exposed to a water-soluble fraction of crude oil during embryonic development
(Journal article; Peer reviewed, 2023)The rise in offshore oil and gas operations, maritime shipping, and tourism in northern latitudes enhances the risk of oil spills to sub-Arctic and Arctic coastal environments. Therefore, there is a need to understand the ... -
Oil droplet interaction with suspended sediment in the seawater column: Influence of physical parameters and chemical dispersants
(Journal article; Peer reviewed, 2014)The interaction of dispersed oil droplets with large diameter suspended particulate materials (SPM) has been little studied. In the current study, particle size, oil characteristics and chemical dispersant significantly ... -
Phase Transitions and Separation Time Scales of CO2-Crude Oil Fluid Systems: Wheel Flow Loop Experiments and Modelling
(Peer reviewed; Journal article, 2020)Presented here is experimental and theoretical work on phase transitions and separation time scales for CO2−crude oil mixtures with CO2 content ranging from pure to 79 mol %. The experimental work was performed using the ... -
Polymer-functionalized silica nanoparticles for improving water flood sweep efficiency in Berea sandstones.
(Peer reviewed; Journal article, 2020)Extraction of oil trapped after primary and secondary oil production stages still poses many challenges in the oil industry. Therefore, innovative enhanced oil recovery (EOR) technologies are required to run the production ... -
Spawning time in adult polar cod (Boreogadus saida) altered by crude oil exposure, independent of food availability
(Journal article; Peer reviewed, 2023)Fish early life stages are well known for their sensitivity to crude oil exposure. However, the effect of crude oil exposure on adults and their gametes during their spawning period is not well studied. Polar cod, a key ... -
Vale crude oil - properties and behaviour at sea
(SINTEF;A25949, Research report, 2014-02-18)A small scale study of the weathering properties of Vale crude oil has been performed at S°C and 13°C in SINTEFs laboratory. The data are used as input for SINTEF's Oil Weathering Model (OWM} to predict the properties and ...
