BLOKKHAV PÅ FJELLTOPPER PÅ YTRE SUNNMØRE OG LANGS INDRE ROMSDALSFJORDEN
(Master thesis, 2022-03-07)Åtte blokkhavsdekkede topper på ytre Sunnmøre og langs indre Romsdalsfjorden viser varierende overflatekarakteristikk og en stor spredning i 10Be-aldre. Aldrene strekker seg fra 15 ± 1 ka til 151 ± 2 ka, uten noen tydelige ... -
Bruk av borekaksmateriale fra letebrønner til studier av erosjon i kvartær.
(Master thesis, 2016-06-15)Naustformasjonen er en glasialt derivert avsetning dannet gjennom de siste 2,8 millioner år (Ma) på midtnorsk sokkel. Formasjonen, som består av fem enheter (Naust-N, -A, -U, -S og - T), består av mektige klinoformer som ... -
Calibration of seismic and well data: Towards Improved Quantitative Seismic Reservoir Characterisation of the Triassic to Middle-Jurassic Gullfaks Reservoir Units of the northern North Sea
(Master thesis, 2011-11-20)Abstract: Characterization and evaluation of (oil and gas) reservoirs is typically achieved using a combination of seismic and well data. It is therefore critical that the two data types are well calibrated to correct and ... -
The Cascadia subduction zone: Kinky or not? An implementation of a 2D background velocity model in teleseismic scattered-wave inversion.
(Master thesis, 2017-06-23)This thesis, within the field of seismology, investigates the process and effect of implementing a complex reference model in a teleseismic migration technique based on the Inverse Generalized Radon Transform. This migration ... -
Centennial variability in Southeast Pacific Hydrography and its link to the Bipolar Seesaw
(Master thesis, 2019-12-11) -
Centennial-millennial scale variations in West Antarctic Ice Sheet discharge and their relationship to climate and ocean changes during the late Holocene
(Master thesis, 2017-06-23)The West Antarctic Ice Sheet (WAIS) may be highly sensitive to future warming and to ocean driven changes in subsurface melting. Understanding this sensitivity is critical as WAIS dynamics are a major source of uncertainty ... -
Characterisation of extensional faults in carbonate rocks (Suez Rift, Egypt); with particular focus on the role of shale smear
(Master thesis, 2012-04-27)The distribution, composition and flow-properties of fault core and shale smear along faults in carbonate reservoirs is less well understood compared to faults in siliciclastic rocks. This study uses field data to characterize ... -
Characterizing the distribution of microbial sulfate reduction in Loki`s Castle hydrothermal system of the Arctic Mid-Ocean Ridge (AMOR)
(Master thesis, 2016-06-01)Studies on the distribution of microbial sulfate reduction, and its impact on the global carbon and sulfur cycle, have mostly been conducted in shallow and deep-marine sediments. Little is therefore known about the ecological ... -
Chemical weathering on Eldsfjellet, Meland municipality, western Norway
(Master thesis, 2012-11-27)The Subject of this master thesis was to define the chemical weathering processes, create a weathering chain from sink to source and to evaluate the degree of weathering on Eldsfjellet, Meland municipality in western Norway. ... -
A Comparative Palynofacies Study of Two Methods Used for Source Rock Validation. A Case Study From a Mississippian Succession on Spitsbergen
(Master thesis, 2017-06-30)This study is conducted on the analysis of twenty-nine kerogen slides of Tournasian and Visean age. The outcrop samples were collected from the Hoelbreen and Birger Johnsonfjellet Members in the Birger Johnsonfjellet section ... -
Comparison of metamorphic evolution and tectonic position of metasediments of the Austevoll islands with rocks from the Samnanger Complex (Major Bergen Arc, Norwegian Caledonides)
(Master thesis, 2015-08-01)Metasedimentary rocks represent a substantial component of the Bergen Arcs System and they are mostly confined to the Minor and Major Bergen Arcs. The arcs represents imbricate structures composed of island arc lithologies, ... -
Controls of basement fabric on cover faulting in strike-slip regimes: analogue physical models of faults using plaster
(Master thesis, 2015-06-01)The full complexity of deformation associated with natural faults is difficult to understand, given the lack of three-dimensional exposure in outcrop and the limitations of seismic resolution in the sub-surface. Analogue ... -
Controls of fault zone structure on synthetic seismic images of the Maghlaq Fault, Malta
(Master thesis, 2020-06-25)Application of seismic reflection data and 2D seismic modelling studies based on field analogues, contribute to closing the scale gap between field observations and interpretation of seismic data. This has improved the ... -
Controls on architecture and seismic imaging of igneous intrusions: Examples from LIDAR outcrop data on Traill Ø (East Greenland) and seismic data from the conjugate Møre Margin
(Master thesis, 2017-06-27)Intrusion of sills into sedimentary successions is a fundamental and widespread process in basins at volcanic rifted margins. Although intrusions emplaced at shallow paleodepths (<1.5 km) are relatively well understood, ... -
Controls on deformation band formation in carbonate grainstones along the Maghlaq Fault, Malta.
(Master thesis, 2018-06-20)Deformation bands are common structures in deformed porous rocks and sediments, that localise strain in millimetre to centimetre thick tabular zones. Deformation bands occurring in siliciclastic rocks have been described ... -
Controls on hydrocarbon column-heights in the Eastern province of Haltenbanken, the Norwegian Sea
(Master thesis, 2016-11-08)Knowledge of controls on hydrocarbon column-heights is highly relevant in hydrocarbon exploration, and important for determination of in-place volumes of prospects. The eastern province of Haltenbanken in the Norwegian Sea ... -
Controls on hydrocarbon column-heights in the north-eastern North Sea
(Master thesis, 2015-06-30)Knowledge about the controls on hydrocarbon column-heights is important in hydrocarbon exploration, as such column heights are the main controlling factor for in-place volumes of prospects. The north-eastern Viking Graben ... -
Controls on river patterns in active tectonic settings in the central Italian Apennines
(Master thesis, 2016-05-31)The central Italian Apennines have gone through a complex evolutionary history, involving compression and subsidence, followed by extension and uplift. The last 3 Ma, the area has experienced active extension, and presently ... -
Crevasses on Svalbard Glaciers: Distribution and Dynamic Controls
(Master thesis, 2015-05-31)Crevasses play a key role in understanding a wide range of glaciological processes, but the current understanding is mainly based on a few key studies. Recent years, studies on crevasse formation have been motivated by the ...
