3D seismic architecture of Pleistocene submarine channels and lobe complexes in the thin-skin deformed slope of the Levantine Basin
(Master thesis, 2013-06-03)The current study describes the architecture of Pleistocene-Holocene depositional features that is affected by the underlying structurally topography. The study area is located offshore Israel, at the Levantine Basin of ... -
3D seismic geomorphology of submarine channel-levee systems in salt-related slope setting: a case study from the western deepwater Egypt
(Master thesis, 2013-07-02)High resolution 3D seismic dataset has been used to examine gravity-driven deposits from the Plesitocene to present-day in the structurally complex area of the western Nile deepwater. The underlying Messinian salt and its ... -
3D seismic investigation of tunnel valleys in the Sørlige Nordsjø II offshore wind site: morphology, cross-cutting relationships, and glacial history
(Master thesis, 2024-06-03)Sørlige Nordsjø II (SNII) is an offshore wind site situated in the Southern Norwegian North Sea and is part of the larger goal to decarbonise the energy industry. The shallow geology of the North Sea is highly heterogeneous, ... -
3D seismic stratigraphy and reservoir characterization of the Chalk Group in the Norwegian Central Graben, North Sea
(Doctoral thesis, 2011-12-08) -
3D stochastic modelling of fault zones in siliciclastic reservoirs. Implications for reservoir description and fluid flow modelling
(Doctoral thesis, 2014-12-16)Fault zones in siliciclastic rocks form distinct volumetric entities and typically exhibit great structural complexity. While it has been considered that the main impact of fault zones to fluid flow is to baffle or block ... -
3D structure and formation of hydrothermal vent complexes at the paleocene-eocene transition, the Møre basin, MID-Norwegian margin
(Peer reviewed; Journal article, 2017-08)The mid-Norwegian margin is regarded as an example of a volcanic-rifted margin, formed prior to and during, Paleogene breakup of the northeast Atlantic. The area is characterized by the presence of voluminous basaltic ... -
4th Nordic Workshop on Cosmogenic Nuclides. Landscape development and geohazards
(Book of abstracts, 2018) -
A detailed field and geochemical investigation of the volcanic sequence in the Grimelid-area: The Solund-Stavfjord Ophiolite Complex
(Master thesis, 2021-12-30)This master thesis focuses on the volcanic sequence of the Solund-Stavfjord Ophiolite Complex (SSOC) in Grimelia, in order to provide more detailed information and a better understanding of the development. The SSOC (443 ... -
A detailed field and geochemical investigation of the volcanic sequence in the Våganes-area: The Solund-Stavfjord Ophiolite Complex
(Master thesis, 2021-06-01)The Solund-Stavfjord Ophiolite Complex (SSOC) is located within the western Norwegian Caledonides and represents a remnant of the youngest phase of oceanic crust formation, dated to Late Ordovician (443 Ma). Detailed field ... -
A high-resolution reconstruction of climate variability at Lagoa Negra Lake Flores, Azores
(Master thesis, 2023-02-07) -
A study of normal fault structure and along-strike variations, based on the northern Moab fault system, Utah.
(Master thesis, 2022-11-07)Fault systems are complex structures where multiple elements generate a network that can deeply impact fluid flow, affecting subsurface hydrocarbon and groundwater reservoirs. However, seismic data from such structures are ... -
Abiotic synthesis of methane and organic compounds in Earth’s lithosphere
(Journal article; Peer reviewed, 2020)Accumulation of molecular hydrogen in geologic systems can create conditions energetically favorable to transform inorganic carbon into methane and other organic compounds. Although hydrocarbons with a potentially abiotic ... -
Abrupt changes in sea ice and dynamics of Dansgaard-Oeschger events
(Doctoral thesis, 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 ... -
Abrupt deglacial changes in the properties of the Atlantic Water entering the Arctic
(Master thesis, 2021-12-15)The Arctic Ocean and Barents Sea are currently experiencing rapid changes, with recent reductions in sea ice being linked to increased heat transport by warm Atlantic Water (AW) flowing into the Arctic Ocean. Knowledge of ... -
Abrupt high-latitude climate events and decoupled seasonal trends during the Eemian
(Peer reviewed; Journal article, 2018-07-20)The Eemian (the Last Interglacial; ca. 129–116 thousand years ago) presents a testbed for assessing environmental responses and climate feedbacks under warmer-than-present boundary conditions. However, climate syntheses ... -
Accretionary history of Lower Ordovician island arc complexes on Bømlo: evidence from detrital zircon dating and geochemical data
(Master thesis, 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 ... -
Accuracy of Fault Sealing in the Oseberg South Area

Acoustic Propagation Underneath the Arctic Sea-ice
(Doctoral thesis, 2018-10-04)The main objective of this project is to study the effect of sea-ice on underwater acoustic wave propagation. Three main parameters define how acoustic waves react to the presence of seaice: (i) the roughness of the underside ... -
Acoustic waveform inversion for ocean turbulence
(Peer reviewed; Journal article, 2017)The seismic oceanography method is based on extracting and stacking the low-frequency acoustic energy scattered by the ocean heterogeneity. However, a good understanding on how this acoustic wavefield is affected by physical ...
