Used vs. new: Does it have consequences for the performance of fishing gear?
(Peer reviewed; Journal article, 2023)Sea trials to test size selectivity equipment in trawls are often limited in time because they are costly, and the results can be influenced by multiple factors that are often overlooked. In the Barents Sea gadoid trawl ... -
Using an omnidirectional video logger to observe the underwater life of marine animals: Humpback whale resting behaviour
(Peer reviewed; Journal article, 2021)Animal-borne video loggers are powerful tools for investigating animal behaviour because they directly record immediate and extended peripheral animal activities; however, typical video loggers capture only a limited area ... -
Using correlative and mechanistic niche models to assess the sensitivity of the Antarctic echinoid Sterechinus neumayeri to climate change
(Peer reviewed; Journal article, 2021)The Southern Ocean is undergoing rapid environmental changes that are likely to have a profound impact on marine life, as organisms are adapted to sub-zero temperatures and display specific adaptations to polar conditions. ... -
Using feedforward neural networks to represent ecosystem dynamics for bioeconomic analysis
(Peer reviewed; Journal article, 2023)We applied feedforward neural networks to represent ecosystem dynamics that are vital to bioeconomic analysis, ecosystem-based management, or what-if analysis regarding the underlying natural resources. Neural networks are ... -
Using mixed models to combine smooth size-selection and catch-comparison curves over hauls
(Journal article; Peer reviewed, 2003)Parametric size-selection curves are often combined over hauls to estimate a mean selection curve using a mixed model in which between-haul variation in selection is treated as a random effect. This paper shows how ... -
Using multivariate autoregressive state-space models to examine stock structure of Greenland halibut in the North Atlantic
(Peer reviewed; Journal article, 2023)Accurate information on population structure is essential for effective fisheries management. Greenland halibut (Reinhardtius hippoglossoides) in the North Atlantic is managed as four separate offshore stocks. We use ... -
Using natural analogues to investigate the effects of climate change and ocean acidification on Northern ecosystems
(Peer reviewed; Journal article, 2018)Northern oceans are in a state of rapid transition. Still, our knowledge of the likely effects of climate change and ocean acidification on key species in the food web, functionally important habitats and the structure of ... -
Using propagules to restore coastal marine ecosystems
(Peer reviewed; Journal article, 2020) -
Using Spatial Validity and Uncertainty Metrics to Determine the Relative Suitability of Alternative Suites of Oceanographic Data for Seabed Biotope Prediction. A Case Study from the Barents Sea, Norway
(Peer reviewed; Journal article, 2021)The use of habitat distribution models (HDMs) has become common in benthic habitat mapping for combining limited seabed observations with full-coverage environmental data to produce classified maps showing predicted habitat ... -
Using the best of two worlds: A bio-economic stock assessment (BESA) method using catch and price data
(Others, 2023)Reliable stock assessments are essential for successful and sustainable fisheries management. Advanced stock assessment methods are expensive, as they require age- or length-structured catch and detailed fishery-independent ... -
Utilising IPCC assessments to support the ecosystem approach to fisheries management within a warming Southern Ocean
(Peer reviewed; Journal article, 2021)Southern Ocean marine ecosystems are highly vulnerable to climate-driven change, the impacts of which must be factored into conservation and management. The Commission for the Conservation of Antarctic Marine Living Resources ... -

UV (280 to 400 nm) optical properties in a Norwegian fjord system and an intercomparison of underwater radiometers
(Journal article; Peer reviewed, 2003-07-17)The depth to which solar ultraviolet (UV) radiation penetrates water columns is highly variable. The range in diffuse attenuation coefficients observed in the clearest ocean waters versus small oligotrophic lakes can be ... -
UV transmission in Norwegian marine waters: controlling factors and possible effects on primary production and vertical distribution of phytoplankton
(Journal article; Peer reviewed, 2005-12-23)We investigated the ultraviolet radiation (UVR) transmission properties of Norwegian oceanic, coastal and fjord waters, and how they influence the primary production and vertical distribution of phytoplankton. Values of ... -
Vaccination with ectoparasite proteins involved in midgut function and blood digestion reduces salmon louse infestations
(Peer reviewed; Journal article, 2020)Infestation with the salmon louse Lepeophtheirus salmonis (Copepoda, Caligidae) affects Atlantic salmon (Salmo salar L.) production in European aquaculture. Furthermore, high levels of salmon lice in farms significantly ... -
Vacuolating encephalopathy and retinopathy associated with a nodavirus-like agent: a probable cause of mass mortality of cultured larval and juvenile Atlantic halibut Hippoglossus hippoglossus
(Journal article; Peer reviewed, 1997-05-22)Reared larval and juvenile Atlantic halibut Hippoglossus hippoglossus collected during incidences of mass mortality in 2 hatcheries were studied by light and electron microscopy. A vacuolating encephalopathy and retinopathy ... -
Validating Finescale Parameterizations for the Eastern Arctic Ocean Internal Wave Field
(Peer reviewed; Journal article, 2023)In the Arctic Ocean, vertical transport of heat by turbulent mixing is ultimately coupled to the sea-ice cover, with immediate and far-reaching impacts on the climate and ecosystem. Unfortunately, direct observations of ... -
Validation and Determination of 25(OH) Vitamin D and 3-Epi25(OH)D3 in Breastmilk and Maternal- and Infant Plasma during Breastfeeding
(Peer reviewed; Journal article, 2020)Vitamin D deficiency in pregnant women and their offspring may result in unfavorable health outcomes for both mother and infant. A 25hydroxyvitamin D (25(OH)D) level of at least 75 nmol/L is recommended by the Endocrine ... -
Validation and reproducibility of a new iodine specific food frequency questionnaire for assessing iodine intake in Norwegian pregnant women
(Journal article; Peer reviewed, 2019)Iodized salt is not mandatory in Norway, and the permitted level of iodine in table salt is low (5 μg/g). Thus, milk and dairy products, fish and eggs are the main dietary sources of iodine in Norway. Mild-to-moderate ... -
