(Master thesis / Masteroppgave, 2016)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We use eighteen timescale-synchronised near-surface temperature reconstructions spanning 10–50 thousand years before present to clarify the regional expression of Dansgaard-Oeschger (D-O) and Heinrich (H) events in the ...
-
(Master thesis / Masteroppgave, 2017)Soil moisture plays an essential role in the land surface energy balance, ap- portioning the available energy into latent and sensible heat. As an impor- tant boundary for the atmosphere, accurate initialization of the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Ongoing climate change is causing fundamental changes in the Arctic, some of which can be hazardous to nature and human activity. In the context of Earth surface systems, warming climate may lead to rising ground temperatures ...

(Master thesis / Masteroppgave, 2015)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Regularization and interpolation of 3D offset classes prior to imaging are an important and challenging step in the marine seismic data processing flow. Here we describe how to perform this task using a deep neural network, ...
-
(Master thesis / Masteroppgave, 2012)Marine seismic acquisition represents one of the most used geophysical exploration techniques employed in the petroleum industry today. However, one major challenge is that the meaningful part of the data will be distorted ...
-
(Master thesis / Masteroppgave, 2011)This thesis investigates the application of the Empirical Mode Decomposition (EMD) and Ensemble Empirical Mode Decomposition (EEMD) techniques in de-noising of marine seismic data. EMD decomposes the seismic dataset into ...
-
(Master thesis / Masteroppgave, 2022)Structural de-risking of Carbon Capture and Storage (CCS) prospects are highly dependent on the effects of faults. Seismic scale faults will dictate how injected CO2 migrate within the subsurface. Depending on fault ...
-
(Doctoral thesis / Doktoravhandling, 2023)The below-ground geological storage of CO2 is seen as an important component to the long-term reduction of global greenhouse gas emissions. One of the difficult tasks is to find large storage locations with good seals ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)We present a multi-temporal digital inventory of Svalbard glaciers with the most recent from the late 2000s containing 33 775 km2 of glaciers covering 57% of the total land area of the archipelago. At present, 68% of the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)In this paper, we semi-automatically classify clean and debris-covered ice for 145 glaciers within Hohe Tauern National Park in the Austrian Alps for the years 1985, 2003, and 2013. We also map the end-summer transient ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Extreme precipitation over the Svalbard Archipelago in the Arctic can have severe consequences for the ecosystem and society. In recent years several extreme precipitation events have been observed at Ny Ålesund, a weather ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Anisotropy of magnetic susceptibility (AMS) and anisotropy of magnetic remanence (AARM and AIRM) are efficient and versatile techniques to indirectly determine rock fabrics. Yet, deciphering the source of a magnetic fabric ...
-
(Master thesis / Masteroppgave, 2006)The aim of this study is to achieve a better understanding of the deep basin and crustal configuration of the transition zone between the Møre and Vøring margins. The area selected is based on the distribution of a set of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Large Igneous Province eruptions coincide with many major Phanerozoic mass extinctions, suggesting a cause-effect relationship where volcanic degassing triggers global climatic changes. In order to fully understand this ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Viscous crustal flow can exhume once deeply buried rocks in postorogenic metamorphic core complexes (MCCs). While migmatite domes record the flow dynamics of anatectic crust, the mechanics and kinematics of solid‐state ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)North-east Java is part of a large sedimentary basin containing hydrocarbon provinces that feature diffuse hydrothermal systems, mud volcanoes, and degassing sites. Seismic profiles acquired to explore the basin reveal a ...
-
(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 to explore natural resources. ...
