2017:00007 A - SubSea Dispersant lnjection (SSDI)- a "state of the art" and the need for further documentations
Daling, Per Snorre; Brakstad, Odd Gunnar; Brandvik, Per Johan; Davies, Emlyn J.; Grøsvik, Bjørn Einar; Meier, Sonnich; Nepstad, Raymond; Nordtug, Trond; Vikebø, Frode Bendiksen (Research report, 2017)The aim of this pre-project has been to give a "State-of the art" and describe the R&D challenges and documentation needed in order to perform robust NEBA (Net Environmental Benefit Analysis) where SubSea Dispersant Injection ... -
An annual profile of the impacts of simulated oil spills on the Northeast Arctic cod and haddock fisherie
Carroll, JoLynn; Frøysa, Håvard Guldbrandsen; Vikebø, Frode Bendiksen; Broch, Ole Jacob; Nepstad, Raymond; Augustine, Starrlight; Skeie, Geir Morten; Bockwoldt, Mathias (Peer reviewed; Journal article, 2022)We simulate the combined natural and pollutant-induced survival of early life stages of NEA cod and haddock, and the impact on the adult populations in response to the time of a major oil spill in a single year. Our ... -

Assessing impacts of simulated oil spills on the Northeast Arctic cod fishery
Carroll, JoLynn; Vikebø, Frode Bendiksen; Howell, Daniel; Broch, Ole Jacob; Nepstad, Raymond; Augustine, Starrlight; Skeie, Geir Morten; Bast, Radovan; Juselius, Jonas (Journal article; Peer reviewed, 2017)We simulate oil spills of 1500 and 4500 m3/day lasting 14, 45, and 90 days in the spawning grounds of the commercial fish species, Northeast Arctic cod. Modeling the life history of individual fish eggs and larvae, we ... -
Embryonic exposure to produced water can cause cardiac toxicity and deformations in Atlantic cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) larvae
Hansen, Bjørn Henrik; Sørensen, Lisbet; Størseth, Trond Røvik; Nepstad, Raymond; Altin, Dag; Krause, Daniel Franklin; Meier, Sonnich; Nordtug, Trond (Peer reviewed; Journal article, 2019)Regular discharges of produced water from the oil and gas industry represents the largest direct discharge of effluent into the marine environment worldwide. Organic compound classes typically reported in produced water ... -
Mind the gap – Relevant design for laboratory oil exposure of fish as informed by a numerical impact assessment model
Frøysa, Håvard Guldbrandsen; Nepstad, Raymond; Meier, Sonnich; Donald, Carey; Sørhus, Elin; Bockwoldt, Mathias; Carroll, JoLynn; Vikebø, Frode Bendiksen (Peer reviewed; Journal article, 2023)Laboratory experiments provide knowledge of species-specific effects thresholds that are used to parameterize impact assessment models of oil contamination on marine ecosystems. Such experiments typically place individuals ...
