Investigation and optimization of OBC sensor array coupling to the seafloor: Novel approach to systematic testing of receiver coupling
(Doctoral thesis, 2013-10-29)The most important challenge for the oil-industry is to increase the recovery rates for existing oil and gas fields and to map fluid movements with time-lapse 4D seismic, ensure caprock integrity and reduce geo-hazards or ... -
An investigation into the dynamical and statistical properties of dominant ocean surface waves using close-range remote sensing
(Doctoral thesis, 2022-09-16)Denne avhandlingen er basert på forskningsresultat som behandler statistiske og dynamiske egenskaper av dominante vinddrevne overflatebølger i åpent hav. Med uttrykket dominante bølger refererer vi her til de største ... -
Investigation into the impact of solid surfaces in aqueous systems
(Doctoral thesis, 2016-03-03)Global warming is upon us. The scientific community is searching for methods of slowing down, preventing and reversing its effects. Carbon dioxide have been at the center of attention the last few decades, being the main ... -
An investigation into the parasitic barnacle, Anelasma squalicola; prevalence, infection behaviour and effects on its host, Etmopterus spinax, in Lusterfjord, Norway.
(Master thesis, 2016-06-27)Anelasma squalicola is a recently evolved parasite. Very little is known of its biology due to its normally low prevalence in deep sea lantern sharks (family: Etmopteridae), in which it is found embedded in the skin. A ... -
An investigation into the potential of a new quantitative DHI method
(Master thesis, 2018-06-22)The seismic response of a layer boundary is dependent on a variety of geological factors and is likely to vary significantly along a given reflector. An aspect that seems to be underutilised in the current DHI methods is ... -
An investigation into the spectral parameters of ultra-low-frequency (ULF) waves in the polar caps and magnetotail
(Journal article; Peer reviewed, 2022)The present case study is focused on fluctuations at ∼ 1.5 mHz observed on open field lines in both of the polar caps in ground-based geomagnetic data and in the electron concentration in the Northern Hemisphere ionosphere. ... -
Investigation of Adsorption Properties in the Metal-Organic Framework CPO-54-Ni
(Master thesis, 2022-06-01) -
Investigation of changes in Briksdalsbreen, western Norway from 1966 - 2020
(Master thesis, 2023-02-06)Briksdalsbreen in western Norway was studied using remote sensing. Sets of optical aerial photographs captured between 1966 to 2020 were used with LiDAR-based Digital Elevation Models (DEMs) and glacier outlines derived ... -
Investigation of crustaceans from shelf areas in the Gulf of Guinea, with special emphasis on Brachyura
(Master thesis, 2009)Crustacean abundance on continental shelves off Nigeria, Cameroon and Gabon in the Gulf of Guinea was investigated in this study. Quantitative data was sampled with a 0.1 m² Van Veen grab during a survey with RV Dr. Fridtjof ... -
Investigation of Gas Adsorption and Separation Properties in the Metal-Organic Framework CPO-54-Co

Investigation of gaseous ammonia for NOx control by SCR on an experimental basis
(Master thesis, 2016-08-15)My dissertation argues which of the two reducing agents, urea or pure ammonia, is better suited for reducing NOx emissions in Marine SCR applications. While the question might seem straight forward, there are several upsides ... -
Investigation of growth performance of post-smolt Atlantic salmon (Salmo salar L.) in semi closed containment system: A big-scale benchmark study
(Journal article; Peer reviewed, 2022)The Norwegian salmon industry faces challenges related to sea lice (Lepeophtheirus salmonis) infestations, escapees, diseases and environmental impact. Semi-closed containment systems (S-CCS) have been proposed to abate ... -
Investigation of instability and turbulence effects on gas explosions: experiments and modelling
(Doctoral thesis, 2018-03-09)Safe design of industrial facilities requires models that can predict the consequences of accidental gas explosions in complex geometries with sufficient accuracy. Computa- tional fluid dynamics (CFD) models are widely ... -
Investigation of long-wave model equations for a liquid CO2-seawater interface in deep water
(Master thesis, 2017-11-04) -
Investigation of Low Salinity Polymer and Surfactant Flooding in Carbonate Reservoir at Reservoir Conditions
(Master thesis, 2018-04-20)It is estimated that 40-60% of the world’s total hydrocarbon production is from carbonate rocks [1]. Carbonate rocks contain the world`s largest fields in the Middle East (i.e., Ghawar Field, Saudi Arabia). Waterflooding ... -
Investigation of nanofluids in alkaline electrolytes: Stability, electrical properties, and hydrogen production
(Journal article; Peer reviewed, 2023)Utilizing solar energy efficiently and manufacturing hydrogen economically are the primary goals in the energy industry. In this paper, we present a novel method to solve both issues by exploiting the electrolysis of ... -
