(Journal article; Peer reviewed, 2015) -
Spatio-temporal dynamics in the dissolved nutrient waste plume from Norwegian salmon cage aquaculture
(Peer reviewed; Journal article, 2018)The aim of this study was to define the waste plume dynamics around a salmon farm in Norway. Systematic water sampling and numerical modeling were implemented to define nutrient concentrations in the upper water column at ... -

Spatiotemporal variability of barium in arctic sea-ice and seawater
(Journal article; Peer reviewed, 2018)Freshwater export from the Arctic is critical in determining the density of water at sites of North Atlantic deep water formation, which in turn influences the global flux of oceanic heat and nutrients. We need geochemical ... -
Spatiotemporal variation in climatic conditions across ecosystems
(Peer reviewed; Journal article, 2021)Environmental variation in time and space affects biological processes such as extinction risk and speed of adaptation to environmental change. The spatial structure of environmental variation may vary among ecosystems, ... -

Spawning energetics and otolith microchemistry provide insights into the stock structure of bonga shad Ethmalosa fimbriata
(Journal article; Peer reviewed, 2019)The gross energy content of spawning batches and the microchemistry of sagittal otoliths in individual female bonga shad Ethmalosa fimbriata were compared between contrasting sampling sites at the Senegalese southern coast ... -
Speciation analysis of organoarsenic species in marine samples: method optimization using fractional factorial design and method validation
(Peer reviewed; Journal article, 2021)Organoarsenic species in marine matrices have been studied for many years but knowledge gaps still exist. Most literature focuses on monitoring of arsenic (As) species using previously published methods based on anion- and ... -
Speciation of zinc in fish feed by size exclusion chromatography coupled to inductively coupled plasma mass spectrometry – using fractional factorial design for method optimisation and mild extraction conditions
(Journal article; Peer reviewed, 2018)Zinc (Zn) is an element essential to all living organisms and it has an important role as a cofactor of several enzymes. In fish, Zn deficiency has been associated with impaired growth, cataracts, skeletal abnormalities ... -
Species composition of three size fractions of zooplankton used in routine monitoring of the Barents Sea ecosystem
(Peer reviewed; Journal article, 2021)Size fractionation with 2000 and 1000 μm screens is used by the Institute of Marine Research in Norway in routine monitoring of zooplankton biomass. This study examines the separation of taxa by this procedure. For copepods ... -
Species-specific discrimination of insect meals for aquafeeds by direct comparison of tandem mass spectra
(Journal article; Peer reviewed, 2019)Insect protein has the potential to become a sustainable feed ingredient for the rapidly growing aquaculture industry. In the European Union, insect derived protein is placed under the same legislation as processed animal ... -
The specification of the data model part in the SAM model matters
(Peer reviewed; Journal article, 2020)This paper considers a general state-space stock assessment modeling framework that integrates a population model for a fish stock and a data model. This way observed data are linked to unobserved quantities in the population ... -

Spring bloom onset in the Nordic Seas
(Journal article; Peer reviewed, 2016-06-15)The North Atlantic spring bloom is a massive annual growth event of marine phytoplankton, tiny free-floating algae that form the base of the ocean's food web and generates a large fraction of the global primary production ... -
Stabilizing selection on Atlantic cod supergenes through a millennium of extensive exploitation
(Peer reviewed; Journal article, 2022)Life on Earth has been characterized by recurring cycles of ecological stasis and disruption, relating biological eras to geological and climatic transitions through the history of our planet. Due to the increasing degree ... -
Stable coexistence of genetically divergent Atlantic cod ecotypes at multiple spatial scales
(Journal article; Peer reviewed, 2018)Coexistence in the same habitat of closely related yet genetically different populations is a phenomenon that challenges our understanding of local population structure and adaptation. Identifying the underlying mechanisms ... -
A Standardized Workflow Based on the STAVIRO Unbaited Underwater Video System for Monitoring Fish and Habitat Essential Biodiversity Variables in Coastal Areas
(Peer reviewed; Journal article, 2021)Essential Biodiversity Variables (EBV) related to benthic habitats and high trophic levels such as fish communities must be measured at fine scale but monitored and assessed at spatial scales that are relevant for policy ... -
