Abstract Variability in the Barents Sea ice cover on interannual and longer time scales has previously been shown to be governed by oceanic heat transport. Based analysis of observations results from an ocean circulation model during event reduced sea northeastern winter 1993, it is that also plays a direct role within seasons. Positive wind stress curl associated Ekman divergence causes coherent increase Atlantic water transport along negative thermal gradient through Sea. The immediate...
The two-branched inflow of warm and saline Atlantic Water to the Arctic is major contributor oceanic heat climate system. However, while entering through Fram Strait retains a large part its as it flows along continental slope, branch flowing shallow Barents Sea releases substantial amount atmosphere. Hence, pathway into degree determines short term fate heat. Here we show events in which relative strengths two branches are affected by wind-induced Ekman-transport off northern shelf....
The transport of pelagic plankton by wind‐driven ocean currents and surface gravity waves is investigated for the example Northeast Arctic cod eggs larvae on coast northern Norway. Previous studies indicate that wave‐induced drift (i.e., Stokes drift) relevant particles in upper ocean. We use an general circulation model together with a numerical wave prediction Lagrangian particle tracking to calculate trajectories fish larvae. Waves are considered not only but also air—sea momentum flux,...
Abstract The Arctic amplification of global warming is causing the Arctic-Atlantic ice edge to retreat at unprecedented rates. Here we show how variability and change in sea cover Barents Sea, largest shelf Arctic, affect population dynamics a keystone species ice-associated food web, polar cod ( Boreogadus saida ). data-driven biophysical model early life stages assembled here predicts strong mechanistic link between survival variation temperature, suggesting imminent recruitment collapse...
Abstract Temperature has been identified in field studies as the physical parameter most influential on growth and recruitment of Arcto-Norwegian cod. However, it pointed out by many authors that temperature this context not only direct effects cod, but also indirect through lower trophic levels. Moreover, said might be a proxy for other climatic parameters. The present paper analyses quantitative larval pelagic juvenile from spawning Lofoten until 0-group fish settle Barents Sea. approach...

Abstract Impacts of climate change on ocean productivity sustaining world fisheries are predominantly negative but vary greatly among regions. We assessed how 39 resources—ranging from data‐poor to data‐rich stocks—in the North East Atlantic most likely affected under intermediate emission scenario RCP4.5 towards 2050. This region is one productive waters in subjected pronounced change, especially northernmost part. In this impact assessment, we applied a hybrid solution combining expert...
Abstract The reproductive success of marine ectotherms is especially vulnerable in warming oceans due to alterations adult physiology, as well embryonic and larval survival prospects. These vital responses may, however, differ considerably across the species' geographical distribution. Here we investigated life history, focusing on ecology, three spatially distant populations (stocks) Atlantic cod ( Gadus morhua , Gadidae) (50–80° N), Irish/Celtic Seas‐English Channel Complex, North Barents...
Abstract Norwegian coastal cod form a stationary population of Atlantic Gadus morhua consisting several genetically separated subpopulations. A small‐scale differentiation in marine populations with pelagic eggs and larvae is made possible by local retention early life stages environments. numerical model was used to simulate the circulation fjord system northern Norway over 2 years different river runoff patterns. The dispersal calculated particle‐tracking that three‐dimensional currents....
The northward flow of warm and saline Atlantic Water through the eastern Nordic Seas sustains a spring-bloom ecosystem that hosts some world's largest commercial fish stocks. Abrupt climatic changes, or changes beyond species-specific thresholds, may have severe effects on species abundance distribution. Here, we utilize numerical ocean model hindcast to explore similarities differences between large-scale anomalies, such as great salinity along-shelf hydrographic anomalies regional origin,...
Abstract Fish stocks vary in abundance. The causes behind the fluctuations may be difficult to determine, especially ones caused by natural fluctuations, but long‐term data series provide indications of mechanisms. Assessments show that recruitment Norwegian spring‐spawning herring ( Clupea harengus, Clupeidae) has remained low since 2004, a year which produced last really rich year‐class. Long time‐series estimated and mean winter temperature ocean showed significant positive correlation...
Atlantic haddock (Melanogrammus aeglefinus) embryos bind dispersed crude oil droplets to the eggshell and are consequently highly susceptible toxicity from spilled oil. We established thresholds for developmental identified any potential long-term or latent adverse effects that could impair growth survival of individuals. Embryos were exposed eight days (10, 80 300 μg oil/L, equivalent 0.1, 0.8 3.0 TPAH/L). Acute delayed mortality observed at embryonic, larval, juvenile stages with IC50 =...

Abstract High and variable mortality during the egg larval stages is thought to be an important source of interannual variability in stock size many marine fish. However, quantitative information about these life stages, especially variability, sparse. Here, we used a time-series covering 35 years (1959–1993) survey data estimate northeast Arctic cod (Gadus morhua) Northeast haddock (Melanogrammus aeglefinus). Using regression approach based on numbers eggs different developmental calculated...
Observations (1978-1991) of distributions pelagic juvenile Northeast Arctic cod (Gadus morhua L.) show that up to 1/3 the year class are dispersed off continental shelf and into deep Norwegian Sea while on way from spring-spawning areas along coast autumn-settlement in Barents Sea. The fate this variable fraction juveniles off-shelf has been an open question ever since Johan Hjort's (1914) seminal work. We have examined both mechanisms causing offspring transport, their subsequent destiny...

Heated debates are currently taking place on whether to open the area of Lofoten and Vesterålen in Northern Norway for petroleum production. Seismic explorations this have indicated promising resources. The is known its unique landscape as a key spawning nursery several economically important fish species. It hosts significant bird colonies world's largest-known deep-sea coral reef. New areas will be opened production only if high environmental value can maintained. A risk analysis approach...
Marine heatwaves (MHWs) are prolonged periods of extreme ocean warming that significantly impact marine ecosystems, fisheries, and aquaculture. In August 2024, northern Norway experienced one the most intense MHWs recorded since 2012, which coincided with a sharp rise in salmon lice infestations at aquaculture sites area. This study investigates atmospheric oceanic drivers this event, focusing on interaction local meteorological conditions large-scale climate variability. Using combination...
