Abrupt changes in sea ice and dynamics of Dansgaard-Oeschger events
(The University of Bergen, 2017-12-01)Changes in sea ice are proposed as an important component in Dansgaard-Oeschger events; the abrupt climate change events that occurred repeatedly during the last ice age. Paleoclimatic reconstructions suggest an expansion ...Doctoral thesis -
Accretionary history of Lower Ordovician island arc complexes on Bømlo: evidence from detrital zircon dating and geochemical data
(The University of Bergen, 2017-06-13)The provenance studies of sedimentary sequences associated with island arc complexes on Bømlo within the ophiolitic terrain of SW Norway has demonstrated that the provenance signature of these sedimentary rocks changed ...Master thesis -

Ambient noise levels and detection threshold in Norway
(Springer, 2016-07)Ambient seismic noise is caused by a number of sources in specific frequency bands. The quantification of ambient noise makes it possible to evaluate station and network performance. We evaluate noise levels in Norway from ...Journal article -
Analyse av seismiske data innenfor Gullfakslisensen - implikasjoner for tolkningen av topp NER
(The University of Bergen, 2003)Master thesis -
Analytical and numerical studies of fluid reservoirs and fracture development in heterogeneous rocks
(The University of Bergen, 2009-06-29)Doctoral thesis -
Anatomy and allostratigraphy of deep-marine Mount Messenger Formation (Miocene), eastern-margin Taranaki Basin, New Zealand
(The University of Bergen, 2003)Purpose of study: Sedimentological description of outcropping deep-water clastics within Mount Messenger Formation. Study area: North-Taranaki coastal region, North Island, New Zealand. Methodology: Mapping on foot and ...Master thesis -
Anisotropic Properties of a Mid-Lithospheric Discontinuity in eastern North America
(The University of Bergen, 2017-06-23)During the last few years the occurrence of a mid-lithospheric discontinuity (MLD) has been observed in lithospheric studies of cratons. Studies using receiver functions have focused mainly on extracting high resolution ...Master thesis -
Applied Structural Geology – Case Studies of Underground Constructions and Rockslides
(The University of Bergen, 2008-02-26)An understanding of the structural elements in the sub-surface is of great importance when establishing new constructions in bedrock, or surveying areas prone to rockslides. In this thesis the focus has been on combining ...Doctoral thesis -
Arctic Holocene proxy climate database – New approaches to assessing geochronological accuracy and encoding climate variables
(Copernicus Publications, 2014-08-29)We present a systematic compilation of previously published Holocene proxy climate records from the Arctic. We identified 170 sites from north of 58° N latitude where proxy time series extend back at least to 6 cal ka (all ...Journal article -
Assessing linkages between ice sheet calving, subpolar gyre hydrography and deep water ventilation during the last glaciation
(The University of Bergen, 2017-06-23)It is commonly postulated that ice sheet dynamics and freshwater perturbations in the North Atlantic were linked to disruptions in deep water circulation and North Atlantic cooling in the past. However, the exact nature ...Master thesis -
Basin-scale architecture of deeply emplaced sill complexes: Jameson Land, East Greenland
(The Geological Society of London, 2016)Igneous sills are common components in rifted sedimentary basins globally. Much work has focused on intrusions emplaced at relatively shallow palaeodepths (0 – 1.5 km). However, owing to constraints of seismic reflection ...Journal article -
Bruddsystem og spenningsfelt tilknyttet tunneltraséen Ringveg Vest i Bergen
(The University of Bergen, 2003)Denne hovedfagsoppgaven er en del av forundersøkelsene som er utført i sammenheng med tunnelprosjektet Ringveg Vest i Bergen kommune, Hordaland, som har driftstart i 2005. Ringveg Vest er planlagt å ligge cirka 4 kilometer ...Master thesis -
Bruk av borekaksmateriale fra letebrønner til studier av erosjon i kvartær.
(The University of Bergen, 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 ...Master thesis -
Calendar year age estimates of Allerød - Younger Dryas sea-level oscillations at Os, western Norway
(John Wiley & Sons Ltd., 2004)A detailed shoreline displacement curve documents the Younger Dryas transgression in western Norway. The relative sea-level rise was more than 9m in an area which subsequently experienced an emergence of almost 60 m. The ...Journal article -
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
(The University of Bergen, 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 ...Master thesis -
Calibration, validation and application of the foraminiferal Mg/Ca. Reconstructing the intermediate water masses structure and origin in the Western Tropical Atlantic
(The University of Bergen, 2015-05-22)The Atlantic Meridional Overturning Circulation (AMOC) plays a central role in the northward distribution of heat. It is a key mechanism in the climatic system that needs to be further understood. Most studies focused on ...Doctoral thesis -
The Cascadia subduction zone: Kinky or not? An implementation of a 2D background velocity model in teleseismic scattered-wave inversion.
(The University of Bergen, 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 ...Master thesis -
The Cenozoic western Svalbard margin: sediment geometry and sedimentary processes in an area of ultraslow oceanic spreading
(Springer, 2011-04-17)The northeastern high-latitude North Atlantic is characterised by the Bellsund and Isfjorden fans on the continental slope off west Svalbard, the asymmetrical ultraslow Knipovich spreading ridge and a 1,000 m deep rift ...Peer reviewedJournal article -
Centennial-millennial scale variations in West Antarctic Ice Sheet discharge and their relationship to climate and ocean changes during the late Holocene
(The University of Bergen, 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 ...Master thesis
