Drivers of Interannual Sea Ice Concentration Variability in the Atlantic Water Inflow Region North of Svalbard
(Peer reviewed; Journal article, 2021)Sea ice concentration along the continental margin of the Arctic Ocean is influenced by a multitude of factors, including local freezing and melting due to atmospheric forcing, lateral advection of sea ice by winds and ... -
Nonlinear crosstalk in broadband multi-channel echosounders
(Peer reviewed; Journal article, 2021)Distortion of acoustic wave caused by nonlinear propagation transfers acoustic energy into higher harmonics of the transmitted signal. When operating several broadband echosounders with non-overlapping frequency bands to ... -
Commitments to sustainable fisheries: Empty words or reality?
(Peer reviewed; Journal article, 2021)The Our Ocean conferences focus on voluntary commitments by different pledgers in support of actions towards a clean, healthy and productive ocean. We analysed the content and summarised the progress of implementation of ... -
Rapid water temperature variations at the northern shelf of the Yellow Sea
(Peer reviewed; Journal article, 2021)During summer, there is great spatial variability in bottom water temperature on the northern shelf of the Yellow Sea. This variability is associated with a thermal front along the shelf. Oscillatory currents from semidiurnal ... -
Genetic response to human-induced habitat changes in the marine environment: A century of evolution of European sprat in Landvikvannet, Norway
(Peer reviewed; Journal article, 2021)Habitat changes represent one of the five most pervasive threats to biodiversity. However, anthropogenic activities also have the capacity to create novel niche spaces to which species respond differently. In 1880, one ... -
Roles of three putative salmon louse (Lepeophtheirus salmonis) prostaglandin E2synthases in physiology and host–parasite interactions
(Peer reviewed; Journal article, 2021)The salmon louse (Lepeophtheirus salmonis) is a parasite of salmonid fish. Atlantic salmon (Salmo salar) exhibit only a limited and ineffective immune response when infested with this parasite. Prostaglandins (PGs) have ... -
Seasonal and interannual variability in abundance and population development of Calanus finmarchicus at the western entrance to the Barents Sea, 1995–2019
(Peer reviewed; Journal article, 2021)Data on copepodid abundance and stage composition of Calanus finmarchicus was collected with seasonal resolution (5–6 times a year) from four stations along an oceanographic transect across the western Barents Sea Opening ... -
Miljøpåvirkning fra dyrking av makroalger — Risikovurdering for norske farvann
(Rapport fra havforskningen;2021 - 24, Research report, 2021)Det er økende interesse for makroalgedyrking, og miljøforholdene langs norskekysten er godt egnet for denne type akvakultivering. Denne rapporten beskriver et faggrunnlag for forvaltning av tillatelser for makroalgekultivering ... -
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 ... -
Maturation in the Barents Sea capelin – Contrasting length- and gonad-based metrics
(Peer reviewed; Journal article, 2021)It is assumed that maturation in the Barents Sea capelin is length-dependent, and that fish of at least 14 cm will potentially spawn. Current assessment and management models for the stock are based on this assumption of ... -
Fisheries acoustics and Acoustic Target Classification - Report from the COGMAR/CRIMAC workshop on machine learning methods in fisheries acoustics
(Rapport fra havforskningen;2021 - 25, Research report, 2021)This report documents a workshop organised by the COGMAR and CRIMAC projects. The objective of the workshop was twofold. The first objective was to give an overview of ongoing work using machine learning for Acoustic Target ... -
Early spring subglacial discharge plumes fuel under-ice primary production at a Svalbard tidewater glacier
(Peer reviewed; Journal article, 2021)Subglacial upwelling of nutrient-rich bottom water is known to sustain elevated summer primary production in tidewater-glacier-influenced fjord systems. However, the importance of subglacial upwelling during the early ... -
Microplastic Fiber Emissions From Wastewater Effluents: Abundance, Transport Behavior and Exposure Risk for Biota in an Arctic Fjord
(Peer reviewed; Journal article, 2021)Microfibers (MF) are one of the major classes of microplastic found in the marine environment on a global scale. Very little is known about how they move and distribute from point sources such as wastewater effluents into ... -
Flexible behaviour in a mesopelagic fish (Maurolicus muelleri)
(Peer reviewed; Journal article, 2021)Variability of mesopelagic scattering layers is often attributed to environmental conditions or multi-species layer composition. Yet, little is known about variation in behaviour among the individuals forming scattering ... -
Genome editing on finfish: Current status and implications for sustainability
(Peer reviewed; Journal article, 2021)Novel genome editing techniques allow for efficient and targeted improvement of aquaculture stock and might be a solution to solve challenges related to disease and environmental impacts. This review has retrieved the ... -
Dense mesopelagic sound scattering layer and vertical segregation of pelagic organisms at the Arctic-Atlantic gateway during the midnight sun
(Peer reviewed; Journal article, 2021)Changes in vertical and spatial distributions of zooplankton and small pelagic fish impact the biological carbon pump and the distribution of larger piscivorous fish and marine mammal species. However, their distribution ... -
Planktic foraminiferal and pteropod contributions to carbon dynamics in the Arctic Ocean (north Svalbard margin)
(Peer reviewed; Journal article, 2021)Planktic foraminifera and shelled pteropods are some of the major producers of calcium carbonate (CaCO3) in the ocean. Their calcitic (foraminifera) and aragonitic (pteropods) shells are particularly sensitive to changes ... -
