One mechanism contributing to co-variability of the Atlantic inflow branches to the Arctic
(Journal article; Peer reviewed, 2013-02-12)The two-branched inflow of warm and saline Atlantic Water to the Arctic is the major contributor of oceanic heat to the Arctic climate system. However, while the Atlantic Water entering the Arctic through the Fram Strait ... -
One-Year Treatment with Olanzapine Depot in Female Rats: Metabolic Effects
(Journal article; Peer reviewed, 2019)Background Antipsychotic drugs can negatively affect the metabolic status of patients, with olanzapine as one of the most potent drugs. While patients are often medicated for long time periods, experiments in rats typically ... -
Ontogenetic movements of cod in Arctic fjords and the Barents Sea as revealed by otolith microchemistry
(Peer reviewed; Journal article, 2020)The distribution of Atlantic cod (Gadus morhua) in northern Norwegian waters is expanding eastward and northward in the Barents Sea and along western Svalbard. In the Arctic fjords of Svalbard, cod has become abundant, but ... -
Ontogenetic spatial constraints of sub-arctic marine fish species
(Peer reviewed; Journal article, 2021)Marine species may respond and adapt to climate change through shifting spatial distributions, but options may be limited by the occupancy of essential habitats which are anchored in space. Limited knowledge of when spatial ... -
Ontogeny-Specific Skeletal Deformities in Atlantic Haddock Caused by Larval Oil Exposure
(Peer reviewed; Journal article, 2021)Bone deformities are one of the main effects of crude oil exposure in marine fish larvae. Craniofacial and jaw deformities, if severe enough, may restrict feeding and ultimately kill the developing larvae. This study aimed ... -
OpenDrift v1.0: A generic framework for trajectory modelling
(Journal article; Peer reviewed, 2018)OpenDrift is an open-source Python-based framework for Lagrangian particle modelling under development at the Norwegian Meteorological Institute with contributions from the wider scientific community. The framework is ... -
Operationalising ODEMM risk assessment for Integrated Ecosystem Assessment scoping: Complexity vs. manageability
(Peer reviewed; Journal article, 2023)Integrated Ecosystem Assessments (IEA) require consideration of the full suite of pressures and impacts affecting ecosystems. However, capacity limitations often severely limit our ability to do everything that we want or ... -
Operationalizing ensemble models for scientific advice to fisheries management
(Peer reviewed; Journal article, 2021)This paper explores the possibility of using the ensemble modelling paradigm to fully capture assessment uncertainty and improve the robustness of advice provision. We identify and discuss advantages and challenges of ... -
Operationalizing marketable blue carbon
(Peer reviewed; Journal article, 2022)The global carbon sequestration and avoided emissions potentially achieved via blue carbon is high (∼3% of annual global greenhouse gas emissions); however, it is limited by multidisciplinary and interacting uncertainties ... -
Operculum PIT tagging: a viable alternative to avoid human consumption in processed salmon
(Peer reviewed; Journal article, 2021)Passive integrated transponder (PIT) tags are commonly used to identify individual fish. However, use of PIT tags in commercial aquaculture research is limited by consumer safety concerns. For farmed fish, it is critical ... -
Opportunities for advancing ecosystem-based management in a rapidly changing, high latitude ecosystem
(Journal article; Peer reviewed, 2018)Unprecedented and rapid changes are ongoing in northern high latitude, marine ecosystems, due to climate warming. Species distributions and abundances are changing, altering both ecosystem structure and dynamics. At the ... -
Opposite selection on behavioural types by active and passive fishing gears in a simulated guppy Poecilia reticulata fishery
(Peer reviewed; Journal article, 2015) -
Optimal estimation of lice release from aquaculture based on ambient temperatures
(Peer reviewed; Journal article, 2020)Models for mapping and forecasting infective pressure from salmon louse Lepeophtheirus salmonis larvae are of major importance in the Norwegian government’s management of salmonid aquaculture. These models use site-reported ... -
Optimization of the Balance between Protein, Lipid and Carbohydrate in Diets for Lumpfish (Cyclopterus lumpus)
(Peer reviewed; Journal article, 2022)The aim of this study was to investigate how the dietary balance between protein, lipid, and carbohydrate affects growth, welfare, and health with focus on immune responses, in lumpfish of body weight ranges 1.7-10 g and ... -
Optimizing copper spheres for precision calibration of hydroacoustic equipment
(Journal article; Peer reviewed, 1982)n operational definition of backscattering cross section is developed for the wideband reception of finite echoes. This is supported by relative measurements on a set of copper spheres by each of four echo sounders operating ... -
Optimizing size selectivity and catch patterns for hake (Merluccius merluccius) and blue whiting (Micromesistius poutassou) by combining square mesh panel and codend designs
(Peer reviewed; Journal article, 2022)Gear modifications in fisheries are usually implemented to obtain catch patterns that meet management objectives. In the Basque bottom trawl fishery, gear regulations include the use of a square mesh panel (SMP) placed at ... -
Optimizing the use of quicklime (CaO) for sea urchin management — A lab and field study
(Peer reviewed; Journal article, 2020)Mass blooms of sea urchins sometimes cause kelp forest collapses that can last for decades. Quicklime has historically been used to reverse those conditions, but the efficacy of liming has varied along latitudinal and ... -
Orientation behavior and swimming speed of Atlantic herring larvae (Clupea harengus) in situ and in laboratory exposures to rotated artificial magnetic fields
(Peer reviewed; Journal article, 2020) -
Origin and expansion of the world’s most widespread pinniped: Range-wide population genomics of the harbour seal (Phoca vitulina)
(Peer reviewed; Journal article, 2022)The harbour seal (Phoca vitulina) is the most widely distributed pinniped, occupying a wide variety of habitats and climatic zones across the Northern Hemisphere. Intriguingly, the harbour seal is also one of the most ... -
Origin of marine invertebrate larvae on an Arctic inflow shelf
(Peer reviewed; Journal article, 2022)Many benthic invertebrate taxa possess planktonic early life stages which drift with water currents and contribute to dispersal of the species, sometimes reaching areas beyond the current ranges of the adults. Until recently, ...
