The fate of the Atlantic Water in the North Icelandic Irminger Current
(Master thesis, 2012-01-19)The fate of the Atlantic Water within the North Icelandic Irminger Current has long been questioned. The North Icelandic Irminger Current flows along the Icelandic shelf area to the west and north of Iceland, bringing warm ... -
Fate of Warm Pacific Water in the Arctic Basin
(Journal article; Peer reviewed, 2021)Pacific Summer Water (PSW) plays a critical role in the ecosystem of the western Arctic Ocean, impacting sea-ice melt and providing freshwater to the basin. Most of the water exits the Chukchi Sea shelf through Barrow ... -
Fault core and its geostatistical analysis: Insight into the fault core thickness and fault displacement
(Master thesis, 2017-06-23)Fault core is a high-strain zone of a fault, which accommodate intense deformation. Due to high strain, complex structures and intensely deformed fault rocks form in the fault core, which again affects the geometry and ... -
Fault core thickness: Insights from siliciclastic and carbonate rocks
(Peer reviewed; Journal article, 2019-06-02)Fault core accommodates intense deformation in the form of slip surfaces and fault rocks such as fault gouge, cataclasite, breccia, lenses, shale smear, and diagenetic features. The complexity and variation in fault core ... -
Fault detection of a wind turbine generator bearing using interpretable machine learning
(Master thesis, 2023-08-10)A wind turbine is subjected to a number of degradation mechanisms during its operational lifetime. If left unattended, the degradation of components will result in poor performance and potential failure. Hence, to mitigate ... -
Fault Facies Modelling: 3D representation of faults in petroleum reservoirs
(Master thesis, 2008-06-30)The purpose of a reservoir model is to act as a tool for optimizing development and production strategies for subsurface hydrocarbon reservoirs. Such a model is intended to be predictive, and to act as a map for the ones ... -
Fault Gouge Characterization in the Øygarden Complex in SW Norway - Relevance for offshore CO2 storage
(Master thesis, 2022-06-01)Pre-existing structures such as faults are common within the North Sea sedimentary basin. Fault-bounded reservoirs provide significant closures for subsurface storing of CO2. An understanding of faults and fault rocks is ... -
Fault sealing and fluid contact control in Gullfaks Sør
(Master thesis, 2023-11-06)In subsurface reservoirs, understanding the fault sealing capacity is important to predict the amount of hydrocarbons present in the reservoirs. Some earlier literature has emphasized using shale gouge ratio (SGR) to predict ... -
Fault sealing in the Krafla-Askja area south of Oseberg
(Master thesis, 2021-06-01)Fault sealing is one of the key factors that control hydrocarbon accumulations. Faults in the subsurface can act as a conduit or a barrier to fluid flow and pressure communication. Understanding fault behavior is essential ... -
Fault tolerant subgraphs with applications in kernelization
(Journal article; Peer reviewed, 2020)In the past decade, the design of fault tolerant data structures for networks has become a central topic of research. Particular attention has been given to the construction of a subgraph H of a given digraph D with as ... -
Fault Zone Characterization and Monitoring of CO2 Storage using Full Waveform Inversion
(Master thesis, 2023-06-01)CO2 storage in geological formations is essential to limit global warming and reduce the effects of climate change. In order to store CO2 safely and prevent leakage, proper sealing mechanisms are required. Faults are complex ... -
Fault-controlled fluid circulation and diagenesis along basin-bounding fault systems in rifts - Insights from the East Greenland rift system
(Journal article; Peer reviewed, 2020-11-05)In marine rift basins, deep-water clastics (>200 m) in the hanging wall of rift- or basin-bounding fault systems are commonly juxtaposed against crystalline “basement” rocks in the footwall. A distinct feature of such fault ... -
Faults architecture and their scaling relationships: Insights into fault core thickness and fault displacement
(Master thesis, 2012-10-01)The purpose of this study is to investigate the statistical characteristics of fault core thickness and fault displacement, and to state the relationship between these two fault attributes. Field work was carried out At ... -
Fauna associated with non-native Sargassum muticum (Fucales, Phaeophyceae) vary with thallus morphology and site type (sounds and bays)
(Journal article; Peer reviewed, 2021)The invasive brown alga Sargassum muticum was first recorded in Norway in 1988 and is presently common in the sublittoral fringe on the sheltered coast in South Norway. Here, results from a study on mesofauna associated ... -
Faunal Colonization of Submarine Mine Tailings: An Intertidal Experiment to Investigate the Infuence of Sediment Organic Carbon Content
(Master thesis, 2014-06-02)Current financial estimates of mineral mining in Norway are approximately 12 billion NOK per year. Most of the industry is located close to the coastline and the inert waste produced ( tailings', granulometrically similar ... -
Faunal trophic structure at hydrothermal vents on the southern Mohn's Ridge, Arctic Ocean
(Peer reviewed; Journal article, 2013)We explore the trophic ecology of heterotrophic fauna associated with a high temperature (HT) vent, 2 low temperature vents, a ‘near-HT vent’ habitat and a non-vent site situated at upper bathyal depths on the southern ... -
Fe(II) stability in coastal seawater during experiments in Patagonia, Svalbard, and Gran Canaria
(Journal article; Peer reviewed, 2020-03)The speciation of dissolved iron (DFe) in the ocean is widely assumed to consist almost exclusively of Fe(III)-ligand complexes. Yet in most aqueous environments a poorly defined fraction of DFe also exists as Fe(II), the ... -
Feasibility of simplified integral equation modeling of low-frequency marine CSEM with a resistive target
(Peer reviewed; Journal article, 2009)We have assessed the accuracy of a simplified integral equation (SIE) modeling approach for marine controlledsource electromagnetics (CSEM) with low applied frequencies and a resistive target. The most computationally ... -
