Per- and polyfluoroalkyl substances (PFAS) in surface sediments of the North-east Atlantic Ocean: A non-natural PFAS background
(Peer reviewed; Journal article, 2024)The extreme persistence and environmental mobility of per- and polyfluoroalkyl substances (PFAS) make their presence ubiquitous in the marine environment. Target analysis of 20 most common PFAS revealed the presence of ... -
Large-scale culturing of the subpolar foraminifera Globigerina bulloides reveals tolerance to a large range of environmental parameters associated to different life-strategies and an extended lifespan
(Peer reviewed; Journal article, 2024)The subtropical to subpolar planktic foraminifera Globigerina bulloides is a calcifying marine protist, and one of the dominant foraminiferal species of the Nordic Seas. Previously, the relative abundance and shell ... -
The underwater soundscape of the North Sea
(Peer reviewed; Journal article, 2024)As awareness on the impact of anthropogenic underwater noise on marine life grows, underwater noise measurement programs are needed to determine the current status of marine areas and monitor long-term trends. The Joint ... -
Contrasting Methane Seepage Dynamics in the Hola Trough Offshore Norway: Insights From Two Different Summers
(Peer reviewed; Journal article, 2024)This study investigates the temporal variations in methane concentration and flare activity in the Hola trough (offshore Norway) during May 2018 and June 2022. Between these time periods, methane seep activity exhibits 3.5 ... -
Antioxidant and osteoinductive properties of organic selenium in microdiets for gilthead seabream (Sparus aurata) larvae
(Peer reviewed; Journal article, 2024)This study investigated the effect of yeast derived selenium (Se) dietary supplementation on larval performance, whole body mineral contents, lipid peroxidation, fatty acid profiles, expression of antioxidants and bone ... -
Intake of different types of seafood and meat and risk of type 2 diabetes in women: a prospective study supported by a dietary intervention in mice
(Peer reviewed; Journal article, 2024)Detailed knowledge regarding the associations between intake of different types of seafood and meat and the risk of type 2 diabetes (T2D), and insight into possible mechanisms are warranted. In this study we aimed to ... -
Blue mussel (Mytilus edulis) silage, a possible low trophic marine protein source for Atlantic salmon (Salmo salar L.)
(Peer reviewed; Journal article, 2024)Blue mussel (Mytilus edulis) could be a promising marine protein source in fish feeds and is of great interest since it can be cultivated along the Norwegian coastline. However, the use of blue mussels in feeds is dependent ... -
The impact of advection on a Subarctic fjord food web dominated by the copepod Calanus finmarchicus
(Peer reviewed; Journal article, 2024) -
The effects of freezing and thawing on Alaria esculenta
(Peer reviewed; Journal article, 2024)Seaweeds must be stabilised shortly after harvesting to avoid rapid deterioration. To handle large amounts harvested during a short period, freezing and frozen storage until utilisation or further processing is one of the ... -
Hazard and catch composition of ghost fishing gear revealed by a citizen science clean-up initiative
(Peer reviewed; Journal article, 2023) -
Interannual differences in sea ice regime in the north-western Barents Sea cause major changes in summer pelagic production and export mechanisms
(Peer reviewed; Journal article, 2023)The Barents Sea is a highly dynamic and productive marine ecosystem and a hotspot of global warming. Variability in sea ice extent is a common feature in the Barents Sea with substantial movements of the sea ice edge on ... -
Diversity, habitat endemicity and trophic ecology of the fauna of Loki’s Castle vent field on the Arctic Mid-Ocean Ridge
(Peer reviewed; Journal article, 2024)Loki’s Castle Vent Field (LCVF, 2300 m) was discovered in 2008 and represents the first black-smoker vent field discovered on the Arctic Mid-Ocean Ridge (AMOR). However, a comprehensive faunal inventory of the LCVF has not ... -
Fasting and its implications for fish welfare in Atlantic salmon aquaculture
(Peer reviewed; Journal article, 2024)Periods of fasting occur for a multitude of reasons in Atlantic salmon aquaculture. Feed withdrawal is widely used prior to transport, parasite treatments, preslaughter and for depuration purposes in recirculating aquaculture ... -
Monitoring litter on Arctic and subarctic shorelines: current status and next steps for monitoring programs
(Peer reviewed; Journal article, 2023)Plastic pollution is ubiquitous, and the Arctic is no exception. One important step to understand the extent of the problem, and to monitor its impact is to have repeatable, comparable, and relevant measures across time ... -
Morphology of Arctic cod (Boreogadus saida) assessed according to habitat preference and age in the Beaufort Sea
(Peer reviewed; Journal article, 2023)The Arctic cod (Boreogadus saida (Lepechin, 1774)) represents the most widespread and abundant fish in the Arctic and is a critical trophic link in its ecosystems. Like many species endemic to the region, it has lost ... -
Dietary electrolyte imbalance alters drinking rate and gastrointestinal tract water fluxes of Atlantic salmon (Salmo salar) smolt in seawater
(Peer reviewed; Journal article, 2024)It was hypothesized that dietary electrolyte balance (dEB) would influence the dynamics of water, ions, and nutrient fluxes in the gastrointestinal tract (GIT) of Atlantic salmon (Salmo salar) smolts differently depending ... -
