(Doctoral thesis / Doktoravhandling, 2021)
In this doctoral thesis, geophysical and geological data are combined with seismic modelling to explore how structures and sedimentary systems in the subsurface can be imaged and mapped. Seismic data of different resolution, ...
(Doctoral thesis / Doktoravhandling, 2021)
Hot igneous intrusions entering organic-rich shale trigger hydrocarbon generation and hydrothermal flow. This may release large quantities of methane to the atmosphere, causing global climate crises, or alternatively form ...
(Doctoral thesis / Doktoravhandling, 2021)
Majority of earthquakes originate at depths of 15-20 kilometers and may propagate on to the surface resulting in catastrophes. Predicting their occurrence is an important question in Earth science. These geological phenomena ...
(Doctoral thesis / Doktoravhandling, 2021)
This thesis describes the Ordovician rocks of the Oppdal area, central Norwegian Caledonides, which record the evolution of a section across the Laurentian margin. By fieldwork, geochronology and geochemistry a revised ...
(Doctoral thesis / Doktoravhandling, 2022)
Coherent swirling bodies of water; mesoscale (10-100 km) vortices, are an essential part of the general ocean circulation. Mesoscale vortices are abundant everywhere in the World Ocean and are vital in upholding equilibrium ...
(Doctoral thesis / Doktoravhandling, 2022)
During seismic acquisition, reflected waves from the subsurface are recorded by sensors in seismic cables in the water column. The measured data are used to create images of the subsurface for the exploration of natural ...
(Doctoral thesis / Doktoravhandling, 2021)
The interplay of the land surface and atmosphere has been studied for a thousand years. Yet, we are still unsure how changes on the land surface impact the atmosphere and vice versa. Further, present-day models rely on a ...
(Doctoral thesis / Doktoravhandling, 2020)
Microcontinents are small continental pieces that have been separated from their parent continent. We often find such microcontinents in oceans that form after the breakup of a large continent (e.g. the North Atlantic, ...
(Doctoral thesis / Doktoravhandling, 2020)
Regionalization is a common approach for runoff prediction in the basin lacking observed discharge data (called ungauged basin). Regionalization is the process of borrowing information (e.g. the hydrological model parameters) ...
(Doctoral thesis / Doktoravhandling, 2020)
Seismic imaging methods have been widely used in the petroleum industry for hydrocarbon exploration and reservoir monitoring. The principle of seismic imaging methods is employing elastic waves generated by seismic source ...
