Distinct genetic clustering in the weakly diferentiated polar cod, Boreogadus saida Lepechin, 1774 from East Siberian Sea to Svalbard
Sanchez, Maria Quintela; Bhat, Shripathi; Præbel, Kim; Gordeeva, Natalia; Seljestad, Gaute Wilhelmsen; Hanebrekke, Tanja Lexau; Mateos-Rivera, Alejandro; Vikebø, Frode Bendiksen; Zelenia, Daria; Cheng, Chi-Hing Christina; Johansen, Torild (Journal article; Peer reviewed, 2021)The cold-adapted polar cod Boreogadus saida, a key species in Arctic ecosystems, is vulnerable to global warming and ice retreat. In this study, 1257 individuals sampled in 17 locations within the latitudinal range of ... -
Earlier hatching and slower growth: a key to survival in the early life history of Norwegian spring spawning herring
Slotte, Aril; Husebø, Åse; Berg, Florian; Stenevik, Erling Kåre; Folkvord, Arild; Fossum, Petter; Mosegaard, Henrik; Vikebø, Frode Bendiksen; Nash, Richard David Marriott (Peer reviewed; Journal article, 2018-10-02)Faster growth in fish larvae is often associated with enhanced survival, and here we investigated whether surviving juvenile Norwegian spring spawning herring Clupea harengus L. generally come from a pool of fast-growing ... -
The effects of spatial and temporal variations in spawning on offspring survival in Northeast Arctic cod
Endo, Clarissa; Skogen, Morten D.; Stige, Leif Christian; Hjøllo, Solfrid Sætre; Vikebø, Frode Bendiksen (Journal article; Peer reviewed, 2024)Climate change and harvesting result in temporal and spatial changes and variability in spawning, and thus in offspring ambient drift conditions. As a result, variable survival of offspring and thereby in recruitment are ... -
Inadequate risk assessments – A study on worst-case scenarios related to petroleum exploitation in the Lofoten area
Hauge, Kjellrun Hiis; Blanchard, Anne; Andersen, Gisle; Boland, Ragnhild; Grøsvik, Bjørn Einar; Howell, Daniel; Meier, Sonnich; Olsen, Erik Joel Steinar; Vikebø, Frode Bendiksen (Peer reviewed; Journal article, 2014-02)Heated debates are currently taking place on whether to open the area of Lofoten and Vesterålen in Northern Norway for petroleum production. Seismic explorations in this area have indicated promising petroleum resources. ... -
Long-Term Statistics of Observed Bubble Depth Versus Modeled Wave Dissipation
Strand, Kjersti Opstad; Breivik, Øyvind; Pedersen, Geir; Vikebø, Frode Bendiksen; Sundby, Svein; Christensen, Kai Håkon (Journal article; Peer reviewed, 2020)Air bubble penetration depths are investigated with a bottom‐mounted echosounder at a seabed observatory in northern Norway. We compare a 1‐year time series of observed bubble depth against modeled and estimated turbulent ... -
Mind the gap – Relevant design for laboratory oil exposure of fish as informed by a numerical impact assessment model
Frøysa, Håvard Guldbrandsen; Nepstad, Raymond; Meier, Sonnich; Donald, Carey; Sørhus, Elin; Bockwoldt, Mathias; Carroll, JoLynn; Vikebø, Frode Bendiksen (Journal article; Peer reviewed, 2023)Laboratory experiments provide knowledge of species-specific effects thresholds that are used to parameterize impact assessment models of oil contamination on marine ecosystems. Such experiments typically place individuals ... -
Northeast Arctic Cod and Prey Match-Mismatch in a High-Latitude Spring-Bloom System
Vikebø, Frode Bendiksen; Broch, Ole Jacob; Kajiya Endo, Clarissa Akemi; Frøysa, Håvard G; Carroll, JoLynn; Juselius, Jonas; Langangen, Øystein Ole Gahr (Journal article; Peer reviewed, 2021)By combining an ocean model, a nutrient-phytoplankton-zooplankton-detritus-model and an individual-based model for early life stages of Northeast Arctic cod we systematically investigate food limitations and growth performance ... -
The Northeast Greenland shelf as a potential habitat for the Northeast Arctic cod
Strand, Kjersti Opstad; Sundby, Svein; Albretsen, Jon; Vikebø, Frode Bendiksen (Peer reviewed; Journal article, 2017-09-26)Observations (1978–1991) of distributions of pelagic juvenile Northeast Arctic cod (Gadus morhua L.) show that up to 1/3 of the year class are dispersed off the continental shelf and into the deep Norwegian Sea while on ... -
Quantitative molecular detection of larval Atlantic herring (Clupea harengus) in stomach contents of Atlantic mackerel (Scomber scombrus) marks regions of predation pressure
Allen, Bridie; Ray, Jessica Louise; Tiedemann, Maik; Komyakova, Valeriya; Vikebø, Frode Bendiksen; Skaar, Katrine Sandnes; Stiasny, Martina H.; Folkvord, Arild; Nash, Richard David Marriott; Stenevik, Erling Kåre; Kjesbu, Olav Sigurd (Journal article; Peer reviewed, 2021)Mortality rates in the early life-history stages of fishes are generally high yet identifying the causes remain unclear. Faltering recruitment rates of Atlantic herring (Clupea harengus) in the Norwegian Sea indicate a ... -
Subsurface maxima in buoyant fish eggs indicate vertical velocity shearand spatially limited spawning grounds
Strand, Kjersti Opstad; Vikebø, Frode Bendiksen; Sundby, Svein; Sperrevik, Ann Kristin; Breivik, Øyvind (Peer reviewed; Journal article, 2019-05)Observed vertical profiles of buoyant particles, in this case pelagic Northeast Arctic (NEA) cod eggs, occasionally deviate from the vertical diffusion‐buoyancy balance by displaying subsurface maxima. Here, we present a ... -
Two decades of match-mismatch in Northeast Arctic cod – Feeding conditions and survival
Kajiya Endo, Clarissa Akemi; Stige, Leif Christian; Skogen, Morten D.; Ciannelli, Lorenzo; Vikebø, Frode Bendiksen (Journal article; Peer reviewed, 2022)The successful recruitment of Northeast Arctic (NEA) cod is thought to depend on sufficient and suitable prey for the newly hatched larvae, in particular the nauplii stages of the lipid-rich calanoid copepod species Calanus ... -
Wind Intensity Is Key to Phytoplankton Spring Bloom Under Climate Change
Vikebø, Frode Bendiksen; Strand, Kjersti Opstad; Sundby, Svein (Peer reviewed; Journal article, 2019-08-30)The onset of the spring bloom (OSB) occurs when phytoplankton growth exceeds losses and is promoted by a transition from deep convection to a shallow mixing layer concurrent with increasing light intensities in nutrient-enriched ...
