Early detection of anthropogenic climate change signals in the ocean interior
(Journal article; Peer reviewed, 2023)Robust detection of anthropogenic climate change is crucial to: (i) improve our understanding of Earth system responses to external forcing, (ii) reduce uncertainty in future climate projections, and (iii) develop efficient ... -
Ecological regime shift in the Northeast Atlantic Ocean revealed from the unprecedented reduction in marine growth of Atlantic salmon
(Peer reviewed; Journal article, 2022)Ecological regime shifts are abrupt changes in the structure and function of ecosystems that persist over time, but evidence of contemporary regime shifts are rare. Historical scale data from 52,384 individual wild Atlantic ... -
Eemian Greenland ice sheet simulated with a higher-order model shows strong sensitivity to surface mass balance forcing
(Peer reviewed; Journal article, 2019)The Greenland ice sheet contributes increasingly to global sea level rise. Its history during past warm intervals is a valuable reference for future sea level projections. We present ice sheet simulations for the Eemian ... -
Effects of an aquaculture pesticide (diflubenzuron) on non-target shrimp populations: Extrapolation from laboratory experiments to the risk of population decline
(Peer reviewed; Journal article, 2019)Marine aquaculture production has lately experienced high economic growth, but also concerns related to production and environmental contamination. For the Atlantic salmon aquaculture industry, the ectoparasitic crustacean ... -
Effects of crude oil and field-generated burned oil residue on Northern shrimp (Pandalus borealis) larvae
(Peer reviewed; Journal article, 2021)In situ burning (ISB) is an oil spill clean-up option used by oil spill responders to mitigate impacts on the marine environment. Despite advantages such as high efficiency and potential applicability for challenging areas ... -
Effects of different photoperiod regimes on the smoltification and seawater adaptation of seawater-farmed rainbow trout (Oncorhynchus mykiss): Insights from Na+, K+-ATPase activity and transcription of osmoregulation and growth regulation genes
(Journal article; Peer reviewed, 2019)Photoperiod is thought to be the main zeitgeber that induces smoltification in salmonids. However, its effects on the smoltification of rainbow trout (Oncorhynchus mykiss) are not fully understood and no published data ... -
Effects of exposing shrimp larvae (Pandalus borealis) to aquaculture pesticides at field relevant concentrations, with and without food limitation
(Peer reviewed; Journal article, 2020)Anti-parasitic drugs used in the aquaculture industry are discharged to the sea after treatment of salmon. In this study, the effects of azamethiphos (AZA) in the Salmosan® formulation and deltamethrin (DEL) in the Alpha ... -
Effects of fasting and water temperatures during transition from freshwater to seawater on juvenile chum salmon growth and metabolism
(Journal article; Peer reviewed, 2021)We examined the combined effects of fasting in freshwater and water temperature during the transition from freshwater to seawater on growth/metabolic parameters in juvenile chum salmon Oncorhynchus keta. Juveniles of 1 g ... -
Effects of First Feeding Regime on Gene Expression and Enzyme Activity in Pikeperch (Sander lucioperca) Larvae
(Peer reviewed; Journal article, 2022)The present study investigates the effects of different feeding regimes with rotifers (Brachionus plicatilis) and Artemia salina on the gene expression and digestive enzymes in pikeperch (Sander lucioperca) larvae at 17 ... -
Effects of nuisance submerged vegetation on the fauna in Norwegian rivers
(Peer reviewed; Journal article, 2021)The abundance of aquatic vegetation is increasing in rivers and lakes worldwide. The aim of this study was to find how the macrophyte Juncus bulbosus Linnaeus affects salmonids and benthic macroinvertebrates in Norwegian ... -
Effects of simulated environmental discharges of the salmon lice pesticides deltamethrin and azamethiphos on the swimming behaviour and survival of adult Northern shrimp (Pandalus borealis)
(Peer reviewed; Journal article, 2021)Swimming behaviour was investigated in adult egg-carrying northern shrimp (Pandalus borealis) exposed to dilute concentrations of the pesticides Alpha Max® (active ingredient deltamethrin) and Salmosan® (active ingredient ... -
Effects of tag type and surgery on migration of Atlantic salmon (Salmo salar) smolts
(Peer reviewed; Journal article, 2022)Tagging salmon smolts to provide information about the timing of outmigration has been a common approach to monitor phenology and model the risk of encountering stressors. However, the validity of tagging has come under ... -
Effects of temperature and photoperiod on rainbow trout (Oncorhynchus mykiss) smoltification and haematopoiesis
(Peer reviewed; Journal article, 2019)Highlights • nkaα1a, nkaα1b and nkcc1a provide relevant information that the NKA activity does not reflect. • While nkaα1a and nkcc1a transcription are mainly regulated by temperature, nkaα1b is regulated mainly by ... -
Effects on early monsoon rainfall in West Africa due to recent deforestation in a convection-permitting ensemble
(Peer reviewed; Journal article, 2023)Tropical deforestation can have a significant effect on climate, but research attention has been directed mostly towards Amazonian deforestation. The southern part of West Africa (a region dependent on rain-fed agriculture ... -
Elevation changes of the Fennoscandian Ice Sheet interior during the last deglaciation
(Journal article; Peer reviewed, 2020)The dynamics of ice sheet interiors during the last deglaciation are poorly constrained, hindering evaluation of ice sheet models. We provide direct evidence of Fennoscandian Ice Sheet (FIS) interior behaviour during ... -
The emergence of the Gulf Stream and interior western boundary as key regions to constrain the future North Atlantic carbon uptake
(Journal article; Peer reviewed, 2023)In recent years, the growing number of available climate models and future scenarios has led to emergent constraints becoming a popular tool to constrain uncertain future projections. However, when emergent constraints are ... -
Emit now, mitigate later? Earth system reversibility under overshoots of different magnitudes and durations
(Peer reviewed; Journal article, 2022)Anthropogenic CO2 emissions cause irreversible climate change on centennial to millennial timescales, yet current mitigation efforts are insufficient to limit global warming to a level that is considered safe. Carbon dioxide ... -
Empirical support for sequential imprinting during downstream migration in Atlantic salmon (Salmo salar) smolts
(Peer reviewed; Journal article, 2022)The precise homing of Atlantic salmon to their natal river and spawning grounds is the foundation for locally adapted genetically differentiated populations across rivers or across river sections. A sequential imprinting ... -
