The International Bathymetric Chart of the Arctic Ocean Version 5.0
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-21)Knowledge about seafloor depth, or bathymetry, is crucial for various marine activities, including scientific research, offshore industry, safety of navigation, and ocean exploration. Mapping the central Arctic Ocean is challenging due to the presence of perennial sea ice, which limits data collection to icebreakers, submarines, and drifting ice stations. The International Bathymetric Chart of the ... -
Norwegian Sea Oceanic Basin and Prograded Margins Composite Tectono-Sedimentary Element
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-05-01)The Norwegian Sea oceanic basins and prograded margins have developed since NE Atlantic break-up in the earliest Eocene. Significant amounts of sediments were fed to the regionally subsiding and widening Norwegian Sea during the Cenozoic as a result of several phases of uplift and erosion of the bounding shelves and their hinterland. Despite an overall passive-margin evolution, the area experienced ... -

Local-Scale Advanced Ship Predictor towards Enhanced Maritime Situation Awareness
(Doctoral thesis; Doktorgradsavhandling, 2025-02-18)With the introduction of autonomous and remotely-controlled ships, close vessel encounter can be associated with higher risk of collision or near-miss scenarios. To avoid these possible incidents, a higher level of situation awareness is required to support the respective decision-making process in maritime navigation. Advanced Ship Predictors (ASPs) are thus proposed to be a solution framework to ... -

Results This work presents seismic evidence for west-dipping, Middle Devonian–Mississippian sills in ... -
An Arctic analogue for the future exploration of possible biosignatures on Enceladus
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-01-23)Methane-rich emissions to the seafloor along the Arctic mid-oceanic ridge hold strong astrobiological significance, as they may represent analogues of putative hydrothermal vent environments on Enceladus. Although such environments on Enceladus would be ideal to sample in future astrobiological missions, this may not be possible due to technological and logistical limitations. As such, searching for ... -

Numerical simulations of coherent blob-like filaments in magnetized plasmas
(Mastergradsoppgave; Master thesis, 2024-12-16)In a world more and more dependent on new and effective energy sources, the introduction of fusion power could prove invaluable. Magnetic confinement of plasma has proved to be difficult, and the curvature of the magnetic field lines in tokamaks give rise to charge polarization at the boundary of the fusion devices leading to cross-field transport. Experiments has shown that the dominating transport ... -

Rhenium-Sulfido and -Dithiolato Corroles: Reflections on Chalcophilicity
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-16)he high-temperature (∼180 °C) reaction between free-base mesotriarylcorroles and Re<sub>2</sub>(CO)<sub>10</sub>, followed by exposure to PCl3 and thiols (or elemental sulfur), affords rhenium-sulfido (ReS) corroles in 67−76% yields. The use of shorter reaction times, lower temperatures (∼130 °C), and a dithiol (e.g., ethane-1,2-dithiol) also allows the isolation of rhenium-dithiolato corroles, ...
