Architecture, Morphometry and Development of Subaqueous Sediment Conduits
Harishidayat, Dicky (Doctoral theses at NTNU;2021:75, Doctoral thesis, 2021)Canyons, channels, and gullies are incised features on the surface of the earth that act as subaqueous conduits for transferring sediment from source areas to basins. For several decades, these subaqueous sediment conduits ... -
Basement High - Related Cretaceous Submarine Fans Growth in Southwestern Barents Sea
Akbar, Yona (Master thesis, 2018)Deep marine sandstone deposit is one of favorable hydrocarbon reservoir in Norwe- gian Basin. However, it remains not being fully understood due to its variation in term of sedimentation process, distribution, and reservoir ... -
Basin Analysis of the Pegasus Basin, New Zealand - A Frontier Basin Uniquely Bounded by Two Opposing Subduction Systems
Sæterdal, Hanne S (Master thesis, 2017)Pegasus Basin is bounded in northwest by the active convergent Australian margin, and in the south by the bathymetric ridge of Chatham Rise, which represents the Mesozoic convergent plate boundary along the Gondwana ... -
Deep-seated faults and hydrocarbon leakage in the Snøhvit Gas Field, Hammerfest Basin, Southwestern Barents Sea
Mohamed, Yasin; Lippard, Stephen John; Omosanya, Kamaldeen Olakunle; Johansen, Ståle Emil; Harishidayat, Dicky (Peer reviewed; Journal article, 2016)High-quality 3D seismic data are used to analyze the history of fault growth and hydrocarbon leakage in the Snøhvit Field, Southwestern Barents Sea. The aim of this work is to evaluate tectonic fracturing as a mechanism ... -
Distributed acoustic sensing of ocean-bottom seismo-acoustics and distant storms: A case study from Svalbard, Norway
Taweesintananon, Kittinat; Landrø, Martin; Potter, John Robert; Johansen, Ståle Emil; Rørstadbotnen, Robin Andre; Bouffaut, Léa; Kriesell, Hannah Joy; Brenne, Jan Kristoffer; Haukanes, Aksel; Schjelderup, Olaf; Storvik, Frode (Peer reviewed; Journal article, 2023)Distributed acoustic sensing (DAS) leverages an ocean-bottom telecommunication fiber-optic cable into a densely sampled array of strain sensors. We demonstrate DAS applications to passive acoustic monitoring (PAM) through ... -
Eavesdropping at the Speed of Light: Distributed Acoustic Sensing of Baleen Whales in the Arctic
Bouffaut, Léa; Taweesintananon, Kittinat; Kriesell, Hannah Joy; Rørstadbotnen, Robin André; Potter, John; Landrø, Martin; Johansen, Ståle Emil; Brenne, Jan Kristoffer; Haukanes, Aksel; Schjelderup, Olaf; Storvik, Frode (Peer reviewed; Journal article, 2022)In a post-industrial whaling world, flagship and charismatic baleen whale species are indicators of the health of our oceans. However, traditional monitoring methods provide spatially and temporally undersampled data to ... -
Electromagnetic Modelling and Inversion of Seafloor Massive Sulphide Deposits - Imaging of SMS Deposits and the Asthenosphere at the Atlantic Mid-Ocean Ridge
Tegnander, Jonas Fagerli (Master thesis, 2017)Seafloor massive sulphides (SMS) are seen as an increasingly important mineral resource for the future. Fewer mineral discoveries are being made in the shallow subsurface onshore, and therefore a more petroleum related ... -
Estimating Net Erosion in the Western Barents Sea
