Accuracy of VMS data from Norwegian demersal stern trawlers for estimating trawled areas in the Barents Sea
(Journal article; Peer reviewed, 2011-06-08)The accuracy of vessel monitoring system (VMS) data, used to determine fishing activity in the trawl fishery for gadoids in the Barents Sea, was studied by observer notes and Global Positioning System (GPS) data from two ... -
Cod, haddock, saithe, herring, and capelin in the Barents Sea and adjacent waters: a review of the biological value of the area
(Journal article; Peer reviewed, 2009-10-09)Cod, haddock, saithe, herring, and capelin are the most important fish species in the Barents Sea and adjacent waters. Ecosystem-based management requires species-specific knowledge of the biological value and vulnerability ... -
Density-dependent migratory waves in the marine pelagic ecosystem
(Journal article; Peer reviewed, 2006-11)The migration of large aggregations of animals that sweep through the landscape is a phenomenon with large consequences in many ecosystems. It has been suggested that such migrations are mediated by resource depletion. ... -
Diurnal variation in bottom trawl survey catches: does it pay to adjust?
(Journal article; Peer reviewed, 2002)The diurnal bias of bottom trawl survey catches is studied with the purpose of adjusting for it and thereby improving the accuracy of abundance estimates. The correction term is estimated with uncertainty and thus ... -
Do abiotic mechanisms determine interannual variability in length-at-age of juvenile Arcto-Norwegian cod?
(Journal article; Peer reviewed, 2002)For the large Arcto-Norwegian stock of cod (Gadus morhua L.) in the Barents Sea, year-to-year variability in growth is well documented. Here three hypotheses for the observed inverse relation between abundance and the mean ... -
From Winter to Late Summer in the Northwestern Barents Sea Shelf: Impacts of Seasonal Progression of Sea Ice and Upper Ocean on Nutrient and Phytoplankton Dynamics
(Peer reviewed; Journal article, 2023)Strong seasonality is a key feature of high-latitude systems like the Barents Sea. While the interannual variability and long-term changes of the Barents Sea are well-documented, the seasonal progression of the physical ... -
Functional relationship between harp seal body condition and available prey in the Barents Sea
(Journal article; Peer reviewed, 2013-06-12)The Barents Sea ecosystem has undergone substantial ecological fluctuations over the past 40 yr, including large variations in the abundance of capelin Mallotus villosus, herring Clupea harrengus, krill Thysanoessa sp. and ... -
Growth of Barents Sea capelin (Mallotus villosus) in relation to zooplankton abundance
(Journal article; Peer reviewed, 2002)Because capelin feed on zooplankton, the availability of the latter may be a limiting factor for capelin growth in at least some areas and at certain times. It was therefore hypothesized that a relationship exists between ... -
Heat in the Barents Sea: transport, storage, and surface fluxes
(Journal article; Peer reviewed, 2010)A column model is set up for the Barents Sea to explore sensitivity of surface fluxes and heat storage from varying ocean heat transport. Mean monthly ocean transport and atmospheric forcing are synthesised and force the ... -
Importance of heat transport and local air-sea heat fluxes for Barents Sea climate variability
(Journal article; Peer reviewed, 2010-07-22)An isopycnic coordinate ocean model has been used to investigate the importance of different mechanisms on the Barents Sea climate variability for the period 1948–2006 Observed and simulated time series from the Kola Section ... -
Indirect climatic forcing of the Barents Sea capelin: a cohort effect
(Journal article; Peer reviewed, 2004-06-08)Planktivorous capelin is a key species in the Barents Sea, being of great importance in the exploitation of plankton production in this subarctic region. However, in years with a successful reproduction of the Norwegian ... -
Investigating the drivers of maturation dynamics in Barents Sea haddock (Melanogrammus aeglefinus)
(Journal article; Peer reviewed, 2011-08)Changes in size and age at maturation of many exploited fish stocks have been investigated and the influences of environmental factors and exploitation have often been inferred, but not explicitly investigated. Here we ... -

Multispecies functional response of the minke whale Balaenoptera acutorostrata based on small-scale foraging studies
(Journal article; Peer reviewed, 2007-07-04)Atlantic minke whales are important predators in the Barents Sea ecosystem; capelin Mallotus villosus, krill Thysanoessa sp. and Meganyctephanes norvegica and herring Clupea harengus are their major prey. Their consumption ... -
One mechanism contributing to co-variability of the Atlantic inflow branches to the Arctic
(Journal article; Peer reviewed, 2013-02-12)The two-branched inflow of warm and saline Atlantic Water to the Arctic is the major contributor of oceanic heat to the Arctic climate system. However, while the Atlantic Water entering the Arctic through the Fram Strait ... -
Petroleum-related hydrocarbons in deep and subsurface sediments from South-Western Barents Sea
(Journal article; Peer reviewed, 2011-06)Subsurface sediments from a pockmark area in South-Western Barents Sea have been earlier found to contain elevated levels of petroleum-related polycyclic aromatic hydrocarbons. This work describes a comprehensive analysis ... -
Reconstructing the stock–recruit relationship for Northeast Arctic cod using a bioenergetic index of reproductive potential
(Journal article; Peer reviewed, 2000)Correlation and simulation analyses suggest that, for the Northeast Arctic (NA) cod stock, the total lipid energy (TLE (kJ)) contained in the livers of mature females is proportional to total egg production, making TLE a ... -
Stock–environment recruitment models for Norwegian spring spawning herring (Clupea harengus)
(Journal article; Peer reviewed, 2002)Different stock–environment recruitment models for Norwegian spring spawning herring (Clupea harengus) are fitted to a time series of spawning stock, recruitment, and temperature data extending back to 1907. In addition ... -
Temporal synchrony and variation in abundance of Atlantic salmon (Salmo salar) in two subarctic Barents Sea rivers: influence of oceanic conditions
(Journal article; Peer reviewed, 2004)Long-term variation in Atlantic salmon (Salmo salar) stocks was analyzed in two Barents Sea rivers, the Teno and Näätämöjoki, that represent the northernmost distribution area of the species. In contrast to most of the ... -
