Omosanya, Kamaldeen Olakunle Leif; Duffaut, Kenneth; Alves, T.M; Eruteya, O.E.; Johansen, Ståle Emil; Waldmann, N. (Peer reviewed; Journal article, 2022)Giant seafloor craters are known along many a continental margin with recurrent mass-wasting deposits. However, the impact of breakup-related magmatism on the evolution of such craters is barely understood. Using high-quality ... -

Modeling and characterizing acoustic signals from cavity clouds generated by marine seismic air-gun arrays: Implications for marine mammals
Khodabandeloo, Babak (Doctoral theses at NTNU;2018:239, Doctoral thesis, 2018)Marine seismic air-gun arrays generate not only low-frequency (<∼300 Hz) acoustic waves which benefit seismic imaging, but also high-frequencies up to tens of kilohertz. Although such high-frequencies are much weaker than ... -

(Journal article; Peer reviewed, 2018)Speculations surround salt deformation in the Mediterranean Basins, both related to the deformation history and the triggers for halokinesis since the onset of the Messinian Salinity Crisis (MSC). This work presents a ... -
Near-surface characterization using shear-wave resonances: A case study from offshore Svalbard, Norway
Taweesintananon, Kittinat; Rørstadbotnen, Robin Andre; Landrø, Martin; Johansen, Ståle Emil; Arntsen, Børge; Forwick, Matthias; Hansen, Alfred (Peer reviewed; Journal article, 2024)Shear-wave (S-wave) resonances are typically observed when the surficial marine sediments over a rock substrate have relatively low S-wave velocities. We observe these phenomena using ocean-bottom fiber-optic distributed ... -
New interpretation of the spreading evolution of the Knipovich Ridge derived from aeromagnetic data
Dumais, Marie-Andrée; Gernigon, Laurent; Olesen, Odleiv; Johansen, Ståle Emil; Brönner, Marco (Peer reviewed; Journal article, 2021)Insights into the spreading evolution of the Knipovich Ridge and development of the Fram Strait are revealed from a recent aeromagnetic survey. As an ultraslow spreading ridge in an oblique system located between the ... -

Origin of anhydrite rocks in the Tromsø Basin, and the evolution of the Tromsø Basin in the light of salt tectonics
Marfo, George (Master thesis, 2016)The Southwestern Barents Sea Shelf is estimated to contain 260 300 billion m3 of gas reserves, of which a significant amount have been proven to be associated with salt structures in the Nordkapp Basin. Salt tectonics ... -
Overpressure Distribution of the Central and Northern Viking Graben - A study of Cretaceous, Jurassic and Triassic sediments
Tjønnfjord, Karl Hampus Viberg (Master thesis, 2017)The North Sea was subjected to massive faulting during the Jurassic period, resulting in a complex graben structure. Consequently, the Viking Graben is heavily compartmentalized and overpressures occur within the Jurassic ... -
Qualitative and Quantitative Evaluation of Reservoir Quality Through Integrated Interpretation of CSEM, Seismic and Well Data - Pingvin Case Example
