Vertical distribution and trophic interactions of zooplankton and fish in Masfjorden, Norway
(Peer reviewed; Journal article, 1990)The distribution, biomass, and predator-prey relationships of the pelagic assemblage in Masfjorden, western Norway, was studied in January 1989. The pelagic biomass was dominated by particulate organic matter. Biomasses ... -
Vertical distribution of inorganic nanoparticles in a Norwegian fjord
(Journal article; Peer reviewed, 2023)Due to the analytical challenges of detecting and quantifying nanoparticles in seawater, the data on distributions of NPs in the marine environment is limited to qualitative studies or by ensemble measurements subject to ... -
Vertical Equilibrium Flow Models with Fully Coupled Geomechanics for CO2 Storage Modeling, Using Precomputed Mechanical Response Functions
(Peer reviewed; Journal article, 2017)Vertical equilibrium (VE) models have proved to be attractive for simulation of \co storage scenarios. Their primary advantage is a substantial reduction in computational requirements compared to standard 3D simulation ... -
Vertical equilibrium models for coupled flow and transport problems
(Master thesis, 2017-12-20)A better understanding of viscous fingering can help to increase the recovery of hydrocarbons. The need for modelling the impact of viscous fingering is great as it largely dictates the sweep quality of hydrocarbons in a ... -
Vertical fluxes of nitrate in the seasonal nitracline of the Atlantic sector of the Arctic Ocean
(Peer reviewed; Journal article, 2016-07)This study compiles colocated oceanic observations of high-resolution vertical profiles of nitrate concentration and turbulent microstructure around the Svalbard shelf slope, covering both the permanently ice-free Fram ... -
Vertical mixing in the Arctic Ocean inferred from eXpendable Current Profilers
(Master thesis, 2011-05-31)Recent and historical data sets from different regions of the Arctic Ocean are analysed using velocity profiles from 127 eXpendable Current Profiler (XCP) deployments from the time period 1993 to 2010. The data sets are ... -
Vertical mixing in the marginal ice zone of the Barents Sea Spatial and temporal variation of oceanic turbulence - observations and numerical model experiments
(Doctoral thesis, 2007-01-12)Vertical mixing affects water mass modification, biological productivity, and chemical fluxes in the ocean, but its response to forcing and variability in time and space in seasonally ice-covered seas is inadequately known. ... -
Vertical salmon lice behaviour as a response to environmental conditions and its influence on regional dispersion in a fjord system
(Peer reviewed; Journal article, 2014)The salmon louse Lepeophtheirus salmonis is a major parasite of salmon, and is able to travel between farms during its pelagic phases. We investigated the spatial dispersion of L. salmonis planktonic stages in the ... -
Vertical structure and seasonal variability of the inflow to the Lofoten Basin inferred from high resolution Lagrangian simulations
(Peer reviewed; Journal article, 2019-11-13)The Lofoten Basin in the eastern Nordic Seas plays a central role in modifying the warm Atlantic Water inflow toward the Arctic Ocean. Here, the Atlantic Water experiences increased residence times, cooling, and substantial ... -
Vertical structure of recent arctic warming from observed data and reanalysis products
(Peer reviewed; Journal article, 2012-03)Spatiotemporal patterns of recent (1979–2008) air temperature trends are evaluated using three reanalysis datasets and radiosonde data. Our analysis demonstrates large discrepancies between the reanalysis datasets, possibly ... -
Vertically averaged equations with variable density for CO2 flow in porous media
(Peer reviewed; Journal article, 2015-03)Carbon capture and storage has been proposed as a viable option to reduce CO 2 emissions. Geological storage of CO 2 where the gas is injected into geological formations for practically indefinite storage, is an integral ... -
Vertically Averaged Models for CO2 Storage in Porous Media
(Master thesis, 2008) -
Vertically integrated models for coupled two‐phase flow and geomechanics in porous media
(Peer reviewed; Journal article, 2016-02)Models of reduced dimensionality have been found to be particularly attractive in simulating the fate of injected CO2 in supercritical state in the context of carbon capture and storage. This is motivated by the confluence ... -
Vertikal utbredelse av glasialt transportert materiale på Gaustatoppen
(Master thesis, 2015-09-03)Gaustatoppen (1883 m o.h.) er en ikonisk fjelltopp i Sør-Norge, der det tidligere er gjort få kvartærgeologiske undersøkelser. På bakgrunn av blokkhavet som dekker fjellmassivet og toppens høyde i forhold til omkringliggende ... -
Vessel recognition in ultrasound images using machine learning techniques
(Master thesis, 2023-06-02)Purpose: Ultrasound is an imaging modality that is commonly used during cardiovascular surgeries globally. The purpose of this thesis is to investigate how machine learning techniques can be used to identify vessel properties ... -
Vêrskipstasjonen MIKE og modellen MICOM - ei samanlikning av observasjonar og modellresultat over 55 år
(Master thesis, 2006)Observasjonar frå MIKE viser ein varm og salt periode som starta i år 2000, og i 2004 vart dei høgste, observerte temperatur og salt verdiane for den atlantiske kjernen registrert her. Oppvarminga nede i djupet pågår stadig, ... -
Vgll3 and the Hippo pathway are regulated in Sertoli cells upon entry and during puberty in Atlantic salmon testis
(Peer reviewed; Journal article, 2018-01-30)Vgll3 is linked to age at maturity in Atlantic salmon (Salmo salar). However, the molecular mechanisms involving Vgll3 in controlling timing of puberty as well as relevant tissue and cell types are currently unknown. Vgll3 ... -
Vgll3 knockout as a means to delay male maturity during large smolt production of Atlantic salmon (Salmo salar L.)
(Master thesis, 2023-12-01)With a 100 billion NOK export value, Atlantic salmon (Salmo salar L.) has become one of the most important export products for Norway. A highly intensified production in recirculating aquaculture systems (RAS) has pushed ... -
The vgll3 Locus Controls Age at Maturity in Wild and Domesticated Atlantic Salmon(Salmo salar L.) Males
(Peer reviewed; Journal article, 2015-11-09)Wild and domesticated Atlantic salmon males display large variation for sea age at sexual maturation, which varies between 1–5 years. Previous studies have uncovered a genetic predisposition for variation of age at maturity ...
