ENSO teleconnections in terms of non-NAO and NAO atmospheric variability
(Journal article; Peer reviewed, 2023)The validity of the long-held understanding or assumption that El Niño-Southern Oscillation (ENSO) has a remote influence on the North Atlantic Oscillation (NAO) in the January–February–March (JFM) months has been questioned ... -
Enthalpies of CH4 and CO2 Hydrate Formation and Dissociation Using Residual Thermodynamics
(Master thesis, 2019-11-27)The problem in the processing industries regarding the formation of gas hydrate in pipelines or equipment have inspired much of the research for better understanding of hydrates. The world’s increasing demands for more ... -
Enthalpies of Hydrate Formation and Dissociation from Residual Thermodynamics
(Journal article; Peer reviewed, 2019-12-11)We have proposed a consistent thermodynamic scheme for evaluation of enthalpy changes of hydrate phase transitions based on residual thermodynamics. This entails obtaining every hydrate property such as gas hydrate ... -
Entropy solutions of the compressible Euler equations
(Journal article, 2015-05-11)We consider the three-dimensional Euler equations of gas dynamics on a bounded periodic domain and a bounded time interval. We prove that Lax-Friedrichs scheme can be used to produce a sequence of solutions with ever finer ... -
Entropy stability for the compressible Navier-Stokes equations with strong imposition of the no-slip boundary condition
(Journal article; Peer reviewed, 2022)We consider the compressible Navier-Stokes equations subject to no-slip adiabatic wall boundary conditions. The main goal is to investigate stability properties of schemes imposing the no-slip condition strongly (injection) ... -
Entropy stable boundary conditions for the Euler equations
(Journal article; Peer reviewed, 2021)We consider the initial-boundary value Euler equations with the aim to derive boundary conditions that yield an entropy bound for the physical (Navier-Stokes) entropy. We begin by reviewing the entropy bound obtained for ... -
Entry into puberty is reflected in changes in hormone production but not in testicular receptor expression in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2019-06-21)Background Puberty in male Atlantic salmon in aquaculture can start as early as after the first winter in seawater, stunts growth and entails welfare problems due to the maturation-associated loss of osmoregulation capacity ... -

Enumerating minimal connected dominating sets in graphs of bounded chordality
(Peer reviewed; Journal article, 2015)Listing, generating or enumerating objects of specified type is one of the principal tasks in algorithmics. In graph algorithms one often enumerates vertex subsets satisfying a certain property. We study the enumeration ... -
Environmental and biological requirements of post-smolt Atlantic salmon (Salmo salar L.) in closed-containment aquaculture systems
(Doctoral thesis, 2017-06-22)Production of Atlantic salmon (Salmo salar L.), exceeds 2 million tonnes globally, and accounts for 90% of the salmon on the market. Presently, the predominant production of post-smolt Atlantic salmon occurs in open sea ... -
Environmental change and atmospheric contamination on Svalbard: sediment chronology
(Peer reviewed; Journal article, 2004)Sediment cores collected from eight lakes along the western coast of Svalbard as part of a project investigating atmospheric pollution and environmental change in Arctic regions were dated radiometrically using natural ... -
Environmental Change at Deep-Sea Sponge Habitats Over the Last Half Century: A Model Hindcast Study for the Age of Anthropogenic Climate Change
(Journal article; Peer reviewed, 2022-03-24)Deep-sea sponges inhabit multiple areas of the deep North Atlantic at depths below 250 m. Living in the deep ocean, where environmental properties below the permanent thermocline generally change slowly, they may not easily ... -
Environmental changes off North Iceland during the deglaciation and the Holocene: foraminifera, diatoms and stable isotopes
(Peer reviewed; Journal article, 2004-02)A combined study of foraminifera, diatoms and stable isotopes in marine sediments off North Iceland records major changes in sea surface conditions since about 15800 cal years (yr) BP. Results are presented from two gravity ... -
Environmental contaminants activate human and polar bear (Ursus maritimus) pregnane X receptors (PXR, NR1I2) differently
(Peer reviewed; Journal article, 2015-04-01)Background Many persistent organic pollutants (POPs) accumulate readily in polar bears because of their position as apex predators in Arctic food webs. The pregnane X receptor (PXR, formally NR1I2, here proposed to be named ... -
Environmental contaminants modulate the transcriptional activity of polar bear (Ursus maritimus) and human peroxisome proliferator-activated receptor alpha (PPARA)
(Peer reviewed; Journal article, 2019-05-06)Peroxisome proliferator-activated receptor alfa (PPARA/NR1C1) is a ligand activated nuclear receptor that is a key regulator of lipid metabolism in tissues with high fatty acid catabolism such as the liver. Here, we cloned ... -

Environmental Drivers of Demersal Fish and Crustacean Community Structure in West Norwegian Fjords
(Master thesis, 2023-09-01)Norwegian fjords, with their complex bathymetry and deep basins, are easily accessible study areas for deep sea communities. Impacts of climate change and increasing pressure from anthropogenic activities on fjord ecosystems, ... -
Environmental drivers of herring growth and how the perception shifts with time series length
(Journal article; Peer reviewed, 2022)Growth is a key component of population dynamics and, thus, fisheries management, yet drivers of its variations are often poorly understood. Using individual data collected over 80 years, we explored how environmental ... -
Environmental effects of offshore produced water discharges: A review focused on the Norwegian continental shelf
(Journal article; Peer reviewed, 2020)Produced water (PW), a large byproduct of offshore oil and gas extraction, is reinjected to formations or discharged to the sea after treatment. The discharges contain dispersed crude oil, polycyclic aromatic hydrocarbons ...
