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 ... -
Crude oil exposure of early life stages of Atlantic haddock suggests threshold levels for developmental toxicity as low as 0.1 μg total polyaromatic hydrocarbon (TPAH)/L
Sørhus, Elin; Sørensen, Lisbet; Grøsvik, Bjørn Einar; Le Goff, Jérémie; Incardona, John P.; Linbo, Tiffany; Baldwin, David; Karlsen, Ørjan; Nordtug, Trond; Hansen, Bjørn Henrik; Thorsen, Anders; Donald, Carey; van der Meeren, Terje; Robson, William; Rowland, Steven J.; Rasinger, Josef; Vikebø, Frode Bendiksen; Meier, Sonnich (Peer reviewed; Journal article, 2023)Atlantic haddock (Melanogrammus aeglefinus) embryos bind dispersed crude oil droplets to the eggshell and are consequently highly susceptible to toxicity from spilled oil. We established thresholds for developmental toxicity ... -
Crude oil exposures reveal roles for intracellular calcium cycling in haddock craniofacial and cardiac development
Sørhus, Elin; Incardona, John P.; Karlsen, Ørjan; Linbo, Tiffany; Sørensen, Lisbet; Nordtug, Trond; van der Meeren, Terje; Thorsen, Anders; Thorbjørnsen, Maja; Jentoft, Sissel; Edvardsen, Rolf; Meier, Sonnich (Journal article; Peer reviewed, 2016-08-10)Recent studies have shown that crude oil exposure affects cardiac development in fish by disrupting excitation-contraction (EC) coupling. We previously found that eggs of Atlantic haddock (Melanogrammus aeglefinus) bind ... -
Effects of mine tailing exposure on early life stages of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus)
Farkas, Julia; Nordtug, Trond; Svendheim, Linn Hjelmeland; D Amico, Elettra; Davies, Emlyn John; Ciesielski, Tomasz Maciej; Jensen, Bjørn Munro; Kristensen, Torstein; Olsvik, Pål Asgeir; Hansen, Bjørn Henrik (Peer reviewed; Journal article, 2021)Mining and processing of minerals produce large quantities of tailings as waste. Some countries, including Norway, allow disposal of mine tailings in the sea. In this study we investigated the impacts of tailings from a ... -
Embryonic crude oil exposure impairs growth and lipid allocation in a keystone Arctic forage fish
Laurel, Benjamin J.; Copeman, Louise; Iseri, Paul; Spencer, Mari; Hutchinson, Greg; Nordtug, Trond; Donald, Carey; Meier, Sonnich; Allan, Sarah; Boyd, Daryle; Ylitalo, Gina; Cameron, James; French, Babara; Linbo, Tiffany; Scholz, Nathaniel; Incardona, John P. (Journal article; Peer reviewed, 2019)As Arctic ice recedes, future oil spills pose increasing risk to keystone species and the ecosystems they support. We show that Polar cod (Boreogadus saida), an energy-rich forage fish for marine mammals, seabirds, and ... -
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 ... -
Monitoring ocean water quality by deployment of lumpfish (Cyclopterus lumpus) eggs: In situ bioaccumulation and toxicity in embryos
Hansen, Bjørn Henrik; Nordtug, Trond; Øverjordet, Ida Beathe; Sørensen, Lisbet; Kvæstad, Bjarne; Davies, Emlyn John; Meier, Sonnich; Gomes, Tania; Brooks, Steven; Farkas, Julia (Peer reviewed; Journal article, 2022)Fish embryos can bioaccumulate and are particularly sensitive to a wide range of contaminants, which makes them suitable sentinels for environmental biomonitoring. However, fish embryos are very rarely utilized in environmental ... -
Oil droplet fouling and differential toxicokinetics of polycyclic aromatic hydrocarbons in embryos of Atlantic haddock and cod
Sørensen, Lisbet; Sørhus, Elin; Nordtug, Trond; Incardona, John P.; Linbo, Tiffany; Giovanetti, Laura; Karlsen, Ørjan; Meier, Sonnich (Peer reviewed; Journal article, 2017)The impact of crude oil pollution on early life stages (ELS) of fish, including larvae and embryos, has received considerable attention in recent years. Of the organic components present in crude oil, polycyclic aromatic ... -
Unexpected Interaction with Dispersed Crude Oil Droplets Drives Severe Toxicity in Atlantic Haddock Embryos
Sørhus, Elin; Edvardsen, Rolf B.; Karlsen, Ørjan; Nordtug, Trond; van der Meeren, Terje; Thorsen, Anders; Harman, Christopher; Jentoft, Sissel; Meier, Sonnich (Journal article; Peer reviewed, 2015-04-29)The toxicity resulting from exposure to oil droplets in marine fish embryos and larvae is still subject for debate. The most detailed studies have investigated the effects of water-dissolved components of crude oil in water ...
