Sedimentology of the Grønfjorden Bed and associated sedimentary deposits: Grønfjorden, Svalbard
(Master thesis, 2018-04-17)The Grønfjorden Bed represents the earliest Paleogene sedimentary deposits in the Central Tertiary Basin on Spitsbergen. It has a patchy distribution, and consists of conglomerates and sandstones of fluvial origin that ... -
Sedimentology of the Neogene Pistarda formation in the Megara Basin; Greece
(Master thesis, 2014-06-02)The Pistarda formation in the Megara Basin has not been studied in detail before. The aim of this thesis is to provide sedimentological and geochemical data, in order to increase our understanding of the depositional ... -
Sedimentology of the Paleogene succession at Calypsostranda, Svalbard
(Master thesis, 2018-04-17)The following study encompasses sedimentological investigations of the Calypsostranda Group. The Calypsostranda Group is comprised of Paleogene sediments where outcrops are well exposed in a coastal section at Renardodden ... -
Sedimentære facies av nedre/midtre jura Realgrunnen-undergruppe og øvre trias De Geerdalenformasjonen
(Master thesis, 2012-10-01)Et detaljert feltarbeid har gitt økt forståelse for eksponerte lagrekker i Agardhbukta på Øst-Spitsbergen. Nye dateringer og sedimentologiske detaljer viser at lagrekken tilhører nedre del av Kapp Toscana-gruppen. Lagrekken ... -
Sedimentære prosesser og avsetningsmiljø i Byfjorden, Vest-Norge
(Master thesis, 2015-06-01)Hovedformålene med denne oppgaven har vært å kartlegge sedimentære prosesser og avsetningsmiljø som har forekommet under og etter den siste deglasiasjonen av det Fennoskandiske isdekket i et vest-norsk fjordsystem. Studien ... -
Segmentation of the Caledonian orogenic infrastructure and exhumation of the Western Gneiss Region during transtensional collapse
(Journal article; Peer reviewed, 2021)The (ultra)high-pressure Western Gneiss Region of the Norwegian Caledonides represents an archetypical orogenic infrastructure of a continent–continent collision zone. To test established exhumation models, we synthesize ... -
Seismic acquisition and analysis in a changing Arctic
(Doctoral thesis, 2020-12-03)In the Arctic, temperatures are regularly low enough that water exists in its frozen state, either in the form of ice, snow, or frozen ground. The effective elastic properties of a material depend on the elastic properties ... -
Seismic Acquisition in a Shallow Marine Sea Ice Covered Environment: The Significance of Survey Geometry and Possible Impacts on Pinnipeds
(Master thesis, 2017-06-27)Seismic surveying of Arctic environments is important for both economic and environmental reasons. The world energy demand is increasing, and new areas need to be explored to cover the demand. One of the new areas where ... -
Seismic Attributes for Carbonates
(Master thesis, 2009-06-02)Seismic attributes can reveal important information about rock properties, and rock physics modeling provide a link between geological and seismic parameters. Carbonate rocks can have wide variations in properties due to ... -
Seismic characterization of reservoirs with multiple fracture sets using velocity and attenuation anisotropy data
(Journal article, 2011)Knowledge about the spatial distribution of the fracture density and the azimuthal fracture orientation can greatly help in optimizing production from fractured reservoirs. Frequency-dependent seismic velocity and attenuation ... -
Seismic data analysis of an onshore-offshore transition zone at Ramså Basin, Norway – a modelling study

Seismic expression of shear zones: Insights from 2-D point-spread-function based convolution modelling
(Journal article; Peer reviewed, 2020)Shear zones are common strain localization structures in the middle and lower crust and play a major role during orogeny, transcurrent movements and rifting alike. Our understanding of crustal deformation depends on our ... -
Seismic hazard in Norway due to large earthquakes
(Master thesis, 2015-06-01)There are many faults located in Norway, posing as potential earthquake sources. Even though the seismicity is characterized as low to moderate, earthquakes of magnitude 3.5 or lower occur regularly. The seismic hazard ... -
Seismic hazard of the Izmir region, Turkey, based on a probabilistic seismic hazard assessment and stochastic ground motion simulations
(Master thesis, 2015-06-01)The purpose of this thesis is to conduct a seismic hazard analysis of the region surrounding Izmir. The chosen area is located in a very active seismic region with a high seismicity due to large amount of earthquakes. In ... -
Seismic Imaging of the Westward Transition From Yakutat to Pacific Subduction in Southern Alaska
(Journal article; Peer reviewed, 2023)Alaska is located at the northernmost point of the interface between the Pacific plate and the North American continent. The subduction of the Pacific plate generates arc volcanoes along the Aleutian trench, which stops ... -
