A 1.3-Myr palaeoceanographic record from the continental margin off Dronning Maud Land, Antarctica
(Peer reviewed; Journal article, 2003-09-15)A 12.5 m long core was retrieved from the continental margin off Dronning Maud Land, Antarctica. Magnetostratigraphy, stable isotopes, 14C accelerator mass spectrometer and amino acid analyses indicate a continuous sediment ... -
1D crustal structure of Albania region
(Journal article; Peer reviewed, 2023)A new crustal 1D layered model for Albania has been determined. The data used consist of P and S readings from 108 evenly distributed and well located earthquakes using the Albanian Seismic Network and nearby seismic ... -
The 2021 MW 6.2 Mamuju, West Sulawesi, Indonesia earthquake: partial rupture of the Makassar Strait thrust
(Journal article; Peer reviewed, 2023)On the 2021 January 15 (local date), an MW 6.2 earthquake struck the Mamuju and Majene regions of West Sulawesi, Indonesia. This event killed more than 100 inhabitants, leaving at least 30 000 people displaced from their ... -
3-D induction log modelling with integral equation method and domain decomposition pre-conditioning
(Journal article; Peer reviewed, 2024)The deployment of electromagnetic (EM) induction tools while drilling is one of the standard routines for assisting the geosteering decision-making process. The conductivity distribution obtained through the inversion of ... -
3-D seismic images of an extensive igneous sill in the lower crust
(Peer reviewed; Journal article, 2019-05-31)When continents rift, magmatism can produce large volumes of melt that migrate upwards from deep below the Earth’s surface. To understand how magmatism impacts rifting, it is critical to understand how much melt is generated ... -
The 30 June 2017 North Sea Earthquake: Location, Characteristics, and Context
(Journal article; Peer reviewed, 2020)The Mw 4.5 southern Viking graben earthquake on 30 June 2017 was one of the largest seismic events in the Norwegian part of the North Sea during the last century. It was well recorded on surrounding broadband seismic ... -
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 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 ... -

A 7000-year record of extreme flood events reconstructed from a threshold lake in southern Norway
(Journal article; Peer reviewed, 2024)Recent decades have witnessed a shift in the seasonality and frequency of river floods in Norway, primarily attributed to contemporary global warming. Such changes necessitate a more comprehensive understanding of climate-flood ... -
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 ... -
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 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 ... -
