NorKyst800: versjoner og arkiver — Oversikt over versjoner og arkiver av NorKyst800 som hittil er brukt for modellering av det fysiske miljø i norsk kystsone - med fokus på implikasjoner for lakselusmodellen til Havforskningsinstituttet
(Rapport fra havforskningen;2022 - 35, Research report, 2022)NorKyst800 er et strømmodellsystem som bruker den åpent tilgjengelige modellen ROMS (Regional Ocean Modeling System) til å gjenskape strøm, hydrografi og vannstand i den norske kystsonen. Modellen har en horisontal oppløsning ... -
North Sea Ecosystem Cruise Report_JH2022206
(Toktrapport;2023 - 2, Research report, 2023)The North Sea Ecosystem cruise (NSEC) is a multi-purpose survey established to monitor distribution and interactions of several components that constitute the lower trophic levels of the pelagic food web including ... -
Northeast Arctic Cod and Prey Match-Mismatch in a High-Latitude Spring-Bloom System
(Peer reviewed; Journal article, 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 ... -

Norwegian fisheries in the Svalbard zone since 1980. Regulations, profitability and warming waters affect landings
(Journal article; Peer reviewed, 2016-02-02)The Svalbard archipelago in the High Arctic is influenced by cold Arctic water masses from the north-east and the warm West Spitsbergen Current flowing northwards along its western coast. The eastern waters and the fjords ... -
Norwegian kelp forest restauration - Kelp restoration actions in Norway, 1988-2022.
(Lecture, 2023)The extensive kelp forests between 58 and 71oN along the Norwegian coastline have suffered greatly from sea urchin grazing since the 1970-ies (Mid and North Norway) and from turf/filamentous algal competition (South and ... -
The Norwegian small scale fishery and data provided for the IHH FAO-Duke-WorldFish project

Not that clean: Aquaculture-mediated translocation of cleaner fish has led to hybridization on the northern edge of the species' range
(Peer reviewed; Journal article, 2021)Translocation and introduction of non-native organisms can have major impacts on local populations and ecosystems. Nevertheless, translocations are common practices in agri- and aquaculture. Each year, millions of wild-caught ... -
Not too slow, not too fast: water currents affect group structure, aggression and welfare in postsmolt Atlantic salmon Salmo salar
(Peer reviewed; Journal article, 2016) -
Notes on age determination, size and age structure, longevity and growth of co-occurring macrourid fishes
(Peer reviewed; Journal article, 2021)Nineteen species of the deep-water fish family Macrouridae inhabit the Mid-Atlantic Ridge (MAR) of the North Atlantic. Size and age structure, longevity and length at age were explored for seven of the more abundant species: ... -
Novel adverse outcome pathways revealed by chemical genetics in a developing marine fish
(Peer reviewed; Journal article, 2017)Crude oil spills are a worldwide ocean conservation threat. Fish are particularly vulnerable to the oiling of spawning habitats, and crude oil causes severe abnormalities in embryos and larvae. However, the underlying ... -
Novel feeding interactions amplify the impact of species redistribution on an Arctic food web
(Peer reviewed; Journal article, 2020)Species are redistributing globally in response to climate warming, impacting ecosystem functions and services. In the Barents Sea, poleward expansion of boreal species and a decreased abundance of Arctic species are causing ... -
Novel large-scale mapping highlights poor state of sea trout populations
(Peer reviewed; Journal article, 2024)1. The state of sea trout in 1251 Norwegian watercourses was assessed based on a scoring system for human pressures, abundance data, and local knowledge. 2. Over 16,000 km of rivers and lakes were available to sea trout ... -
A novel lice control method: photochemical treatment (Photolice)
(Rapport fra havforskningen;2023 - 31, Research report, 2023)Control of salmon lice has long been the biggest challenge for the further development of a sustainable industry. Preventive measures are expected to play an increasing role, but experience suggests that drug treatment ... -
A novel method for the rapid enumeration of planktonic salmon lice in a mixed zooplankton assemblage using fluorescence
(Peer reviewed; Journal article, 2022)The relative rarity of the planktonic larval stages of salmon lice in comparison to other animals captured in a zooplankton assemblage is an obstacle to estimating their abundance and distribution. Due to the labour ... -
A novel probabilistic survey method for at sea sampling in pelagic fisheries – the Norwegian catch sampling lottery
(Peer reviewed; Journal article, 2022)Reliable information on the age- and size-structure of the annual harvest of major commercial fish stocks is crucial input to analytical stock assessments. Such information is usually obtained from landing data (census of ... -
Novel tag-based method for measuring tailbeat frequency and variations in amplitude in fish
(Peer reviewed; Journal article, 2023)The tailbeat frequency (TBF) together with tailbeat amplitude (TBA) of fish are tightly correlated with swimming speed. In addition, these parameters can be used as indicators of metabolic rate and general activity level, ... -
Numerous Sublinear Sets of Holes in Sediment on the Northern Mid-Atlantic Ridge Point to Knowledge Gaps in Understanding Mid-Ocean Ridge Ecosystems
(Peer reviewed; Journal article, 2022)On 13 July 2004, during an expedition exploring biodiversity along the northern Mid-Atlantic Ridge, an ROV dive recorded videos of numerous sublinear sets of holes in sediment at ca. 2,082 m depth. The location was north ... -
