The Geometry and Evolution of Supra-Salt Normal Fault Arrays
(Doctoral thesis, 2016-06-22)The structural style and evolution of normal fault arrays above mobile salt is less understood compared to those developed in rifts where strong variations in mechanical stratigraphy are absent. This research was performed ... -
Geophysical investigation of the Hugin Fracture, a soft-sediment seafloor fracture on the Utsira High, North Sea. Implications for subsurface fluid migration
(Doctoral thesis, 2019)The 2011 discovery of the Hugin Fracture, a 3.5 km long seafloor fracture on the Utsira High, shows that large-scale, unexpected features can still be found in ostensibly wellmapped, highly industrialized offshore areas ... -
Glacier dynamics in the fjords of Svalbard, inferred from submarine landforms and marine sediment cores
(Doctoral thesis, 2017-09-19)This thesis presents a reconstruction of the late Weichselian, deglacial and Holocene glacial history of the Svalbard fjords, focusing on eastern Svalbard. The study is based on high-resolution multibeam data, shallow ... -
Global Characterization of Modern Depositional Environments for Reservoir Analogues
(Doctoral thesis, 2015-05-12)The advent of significant volumes of freely available, global scale, remote sensing and Geographical Information Systems (GIS) data has revolutionized the study of modern depositional systems, especially with reference to ... -
High resolution seismic stratigraphic analysis: An integrated approach to the subsurface geology of the SE Persian Gulf
(Doctoral thesis, 2006-06-30) -
Holocene variations in atmospheric circulation in the North Atlantic region reconstructed from lake sediments
(Doctoral thesis, 2016-06-17)Holocene variations in atmospheric circulation in the North Atlantic region have been reconstructed, based on three individual lake sediment studies from sites along the coast of Norway and Svalbard. This thesis contributes ... -
Hydrography in the Nordic Seas During Dansgaard-Oeschger Events 8-5
(Doctoral thesis, 2019-06-14)The modern rapidity of Arctic sea ice loss and rise in Arctic air and ocean temperatures is pushing research to understand mechanisms for abrupt climate fluctuations. Resolving the mechanisms of past abrupt changes is a ... -
Ice sheets, oceanic circulation & sea surface conditions: the NW European margin during the last 35,000 years
(Doctoral thesis, 2018-04-20)The north-western European continental margin provides a key area for detailed investigations of changes within the inflow of Atlantic warm surface currents, fluctuations in continental ice sheets and the corresponding ... -
Ice-sheet dynamics and glacial development of the Norwegian continental margin during the last 3 million years
(Doctoral thesis, 2007-06-29)This thesis is mainly about the dynamics of the palaeo-ice sheets that covered Scandinavia, Barents Sea and Svalbard during the last glaciation. Morphological interpretation of regional and detailed bathymetric data sets ... -
Identifying flood deposits in lake sediments: Changing frequencies and potential links to long-term climate change
(Doctoral thesis, 2011-05-26)This thesis consists of an introduction and three individual papers that investigate the possibility for identifying the sedimentary imprint of catchment processes in lake sediments, emphasising on extreme events and in ... -
Impact of diagenesis on seismic properties of siliciclastic rocks
(Doctoral thesis, 2006-04-25) -
Impact of geological heterogeneity on CO2 sequestration: from outcrop to simulator
(Doctoral thesis, 2013-12-16)Increased anthropogenic emission of carbon dioxide (CO2) into the Earth’s atmosphere since the industrial revolution has enhanced the greenhouse effect and contributed to global climate change. Controlling atmospheric CO2 ... -
The influence of the pre-existing structuring on the evolution and geometry of extensional fault systems in the northern North Sea rift system
(Doctoral thesis, 2017-10-03)The structural style and fault evolution in rift basins affected by pre-existing structuring differ considerably from those developing above the homogeneous crust, because pre-existing structures are likely to reactivate ... -
An integrated approach for seismic characterization of carbonates
(Doctoral thesis, 2010-11-09) -
An integrated geological characterization of marine ground conditions in the North Sea
(Doctoral thesis, 2023-11-30)Geologiske karakterisering av marine grunnforhold for ankre og fundamenter for vindturbinder store vindkraftverk til havs er et relativt nytt felt. Som sådan er etableringen av beste praksis for integrering av geologiske, ... -
Integration of ground-based hyperspectral and lidar scanning in virtual outcrop geology
(Doctoral thesis, 2011-01-28)The potential to visualize and analyse geological outcrops in a 3D environment has made terrestrial laser scanning (TLS) a standard method in geological field studies. Lidar models can be integrated with high resolution ... -
The interplay between surface processes and tectonics in the actively extending central Italian Apennines
(Doctoral thesis, 2020-06-08)The overall objective of this project is to improve our understanding of the interplay between surface processes and tectonics in active continental rifts, based on the central part of the Italian Apennines. Three key ... -
Intraplate Earthquakes in Nordland, Northern Norway : Insight from Seismic Tomography and Earthquake Analysis
(Doctoral thesis, 2023-01-19)Intraplate-seismisitet refererer til jordskjelv i områder som ikke er påvirket av prosessene langs aktive plategrenser. Det totale seismiske momentet utløst fra intraplatejordskjelv er mye mindre enn fra jordskjelv i ... -
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 ... -
