Molecular and physiological responses to long-term carbon dioxide exposure in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2019)Optimal water quality is vital for the growth of Atlantic salmon aquaculture production. Recent data showed that Atlantic salmon feed intake and growth reduce linearly with increasing water carbon dioxide (CO2) concentrations, ... -
Moving cleaner fish from the wild into fish farms: A zero-sum game?
(Journal article; Peer reviewed, 2022)Fish that engage in mutualistic cleaning behaviour (‘cleaner fishes’) have recently been popularized as a nature-based method of controlling ectoparasite outbreaks in fish farms. Outbreaks impact animal welfare and threaten ... -
Moving forward in microplastic research: A Norwegian perspective
(Peer reviewed; Journal article, 2021)Given the increasing attention on the occurrence of microplastics in the environment, and the potential envi-ronmental threats they pose, there is a need for researchers to move quickly from basic understanding to applied ... -
A multi-decadal record of oceanographic changes of the past ~165 years (1850-2015 AD) from Northwest of Iceland
(Peer reviewed; Journal article, 2020)Extending oceanographic data beyond the instrumental period is highly needed to better characterize and understand multi-decadal to centennial natural ocean variability. Here, a stable isotope record at unprecedented ... -
Multi-decadal warming of Atlantic water and associated decline of dissolved oxygen in a deep fjord
(Peer reviewed; Journal article, 2019)Previous studies have shown decline in dissolved oxygen of the ocean basins. A hypothesis for this development is that ocean warming through increased stratification has caused reduced ventilation of the interior ocean. ... -
A multi-model CMIP6-PMIP4 study of Arctic sea ice at 127 ka: sea ice data compilation and model differences
(Peer reviewed; Journal article, 2021)The Last Interglacial period (LIG) is a period with increased summer insolation at high northern latitudes, which results in strong changes in the terrestrial and marine cryosphere. Understanding the mechanisms for this ... -
The Multi-Scale Interactions of Atmospheric Phenomenon in Mean and Extreme Precipitation
(Peer reviewed; Journal article, 2023)Climate change increases the frequency and intensity of extreme precipitation, which in combination with rising population enhances exposure to major floods. An improved understanding of the atmospheric processes that cause ... -
Multi-Sensor Analysis of Snow Seasonality and a Preliminary Assessment of SAR Backscatter Sensitivity to Arctic Vegetation: Limits and Capabilities
(Peer reviewed; Journal article, 2022)Snow melt timing and the last day of snow cover have a significant impact on vegetation phenology in the Svalbard archipelago. The aim of this study is to assess the seasonal variations of the snow using a multi-sensor ... -
Natural and anthropogenic drivers of escaped farmed salmon occurrence and introgression into wild Norwegian Atlantic salmon populations
(Peer reviewed; Journal article, 2022)Marine aquaculture of Atlantic salmon (Salmo salar) is a relatively new industry where breeding programs have led to rapid genetic change in the captive populations that were built up alongside conspecific wild individuals. ... -
Negative impacts of the sea lice prophylactic emamectin benzoate on the survival of hatchery released salmon smolts in rivers
(Peer reviewed; Journal article, 2020)Emamectin benzoate (EB) is a prophylactic pharmaceutical used to protect Atlantic salmon (Salmo salar) smolts migrating out of rivers and into the ocean against sea lice parasites. Randomized control trials comparing the ... -
Neural activation in photosensitive brain regions of Atlantic salmon (Salmo salar) after light stimulation
(Peer reviewed; Journal article, 2021)Photoreceptive inputs to the teleost brain are perceived as image of the visual world and as photo-modulation of neuroendocrine and neuronal signals. The retina and pineal organ are major receptive organs with projections ... -
New ecosystems in the deep subsurface follow the flow of water driven by geological activity
(Peer reviewed; Journal article, 2019)Eukarya have been discovered in the deep subsurface at several locations in South Africa, but how organisms reach the subsurface remains unknown. We studied river-subsurface fissure water systems and identified Eukarya ... -
New flood frequency estimates for the largest river in Norway based on the combination of short and long time series
(Peer reviewed; Journal article, 2020)The Glomma River is the largest in Norway, with a catchment area of 154 450 km2. People living near the shores of this river are frequently exposed to destructive floods that impair local cities and communities. Unfortunately, ... -
A New Species of Osedax (Siboglinidae: Annelida) From Colonization Experiments in the Arctic Deep Sea
(Peer reviewed; Journal article, 2020)Large parcels of organic matter in the deep sea, such as whale carcasses, harbor a very specialized fauna, most famously the bone-eating worms in the genus Osedax (Annelida, Siboglinidae). Although Osedax was first described ... -
New wine in old bottles: Modification of the Na+/K+-ATPase enzyme activity assay and its application in salmonid aquaculture
(Peer reviewed; Journal article, 2023)The Na+, K+ ATPase (NKA) enzyme is important to generate the transmembrane ion gradient in the gills, intestine, and kidneys, hence, is vital for secondary transport of fluids and different solutes in teleosts. Gill NKA ... -
Nitrogen fixation rates in the Guinea Dome and the equatorial upwelling regions in the Atlantic Ocean
(Peer reviewed; Journal article, 2023)Biological nitrogen fixation is a key process balancing the loss of combined nitrogen in the marine nitrogen cycle. Its relevance in upwelling or high nutrient regions is still unclear, with the few available studies in ... -
NorCPM1 and its contribution to CMIP6 DCPP
(Journal article; Peer reviewed, 2021)The Norwegian Climate Prediction Model version 1 (NorCPM1) is a new research tool for performing climate reanalyses and seasonal-to-decadal climate predictions. It combines the Norwegian Earth System Model version 1 (NorESM1) ... -
North Atlantic Oscillation in winter is largely insensitive to autumn Barents-Kara sea ice variability
(Peer reviewed; Journal article, 2021)Arctic sea ice extent in autumn is significantly correlated with the winter North Atlantic Oscillation (NAO) in the satellite era. However, questions about the robustness and reproducibility of the relationship persist. ... -
The northern European shelf as an increasing net sink for CO2
(Peer reviewed; Journal article, 2021)We developed a simple method to refine existing open-ocean maps and extend them towards different coastal seas. Using a multi-linear regression we produced monthly maps of surface ocean fCO2 in the northern European coastal ... -
