An annual profile of the impacts of simulated oil spills on the Northeast Arctic cod and haddock fisherie
(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
(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 ... -
Catches in abandoned snow crab (Chionoecetes opilio) pots in the Barents Sea
(Peer reviewed; Journal article, 2021)During a 2018 retrieval cruise for abandoned snow crab (Chionoecetes opilio) pots in the Barents Sea, approximately 8600 pots abandoned 1.5 years earlier were recovered. Forty-three percent of a subsample of 1000 pots ... -

Combined effects of fishing and oil spills on marine fish: Role of stock demographic structure for offspring overlap with oil
(Journal article; Peer reviewed, 2018)It has been proposed that the multiple pressures of fishing and petroleum activities impact fish stocks in synergy, as fishing-induced demographic changes in a stock may lead to increased sensitivity to detrimental effects ... -
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
(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 ... -
Distinct polymer-dependent sorption of persistent pollutants associated with Atlantic salmon farming to microplastics
(Peer reviewed; Journal article, 2022)Interactions of microplastics and persistent organic pollutants (POPs) associated with Atlantic salmon farming were studied to assess the potential role of microplastics in relation to the environmental impact of aquaculture. ... -
Distribution of natural and anthropogenic radionuclides in sediments from the Vefsnfjord, Norway
(Peer reviewed; Journal article, 2021)Areas in central Norway were heavily contaminated with fallout from the Chernobyl accident in 1986. In this study, we assess 137Cs in surface sediments and sediment cores collected in the Vefsnfjord in Nordland county. ... -
Effects of depth and overgrowth of ephemeral macroalgae on a remote subtidal NE Atlantic eelgrass (Zostera marina) community
(Peer reviewed; Journal article, 2022)We conducted a short-term field sampling complemented with time integrating stable isotope analysis to holistically investigate status and ecological interactions in a remote NE Atlantic Zostera marina meadow. We found ... -

Environmental toxicology: Population modeling of cod larvae shows high sensitivity to loss of zooplankton prey
(Journal article; Peer reviewed, 2010-12-30)Two factors determine whether pollution is likely to affect a population indirectly through loss of prey: firstly, the sensitivity of the prey to the pollutants, and secondly, the sensitivity of the predator population to ... -
Geochronology of sediment cores from the Vefsnfjord, Norway
(Peer reviewed; Journal article, 2021)The sedimentary environment is a repository and carrier for a variety of pollutants, and sediment transport from land to coastal areas is an important environmental process. In the present study, we use 210Pb/226Ra and ... -
Ghost fishing efficiency by lost, abandoned or discarded pots in snow crab (Chionoecetes opilio) fishery
(Peer reviewed; Journal article, 2023)Marine pollution by lost, abandoned or otherwise discarded fishing gear (ALDFG) often has negative impact on the ecosystem through plastic pollution and continuous capture of marine animals, so-called “ghost fishing”. ALDFG ... -
Increased barium levels in recent marine sediments from the Norwegian and Barents Seas suggest impact of hydrocarbon drilling and production
(Peer reviewed; Journal article, 2023)Barium (Ba) in recent marine sediments can originate from natural and anthropogenic sources including discharges from the oil and gas industry. In this study, we use data from the Norwegian and Barents Seas to assess whether ... -
Litter on the seafloor along the African coast and in the Bay of Bengal based on trawl bycatches from 2011 to 2020
(Peer reviewed; Journal article, 2022)We present the occurrence of seafloor litter on the coast of Africa and in the Bay of Bengal based on records from the EAF-NANSEN Programme in 2011 to 2020. Litter bycatch records from 534 bottom trawls were standardized ... -
Marine litter in the Nordic Seas: Distribution composition and abundance
(Peer reviewed; Journal article, 2017)Litter has been found in all marine environments and is accumulating in seabirds and mammals in the Nordic Seas. These ecosystems are under pressure from climatic change and fisheries while the human population is small. ... -
Marine microplastic debris: An emerging issue for food security, food safety and human health
(Journal article; Peer reviewed, 2018)Recent studies have demonstrated the negative impacts of microplastics on wildlife. Therefore, the presence of microplastics in marine species for human consumption and the high intake of seafood (fish and shellfish) in ... -
Measurements of underwater noise radiated by commercial ships at a cabled ocean observatory
(Journal article; Peer reviewed, 2020)Measurements of underwater noise radiated under ship normal operations are presented. The acoustic data, from the cabled ocean observatory, are analyzed under each identified ship passage, which was obtained by the Automatic ...
