(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The most prolific reservoir intervals in the Barents Sea are found in the Upper Triassic to Middle Jurassic Realgrunnen Subgroup, deposited during a major change in the structural evolution of the basin which greatly ...
-
(Master thesis / Masteroppgave, 2019)The evolution of the Øygarden Fault Complex (ØFC) footwall is studied using tectonostratigraphic analysis of 3D seismic reflection data. The footwall is comprised of a North-South trending graben bounded by three reactivated ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The tropical tropopause layer (TTL) is the transition region between the well-mixed convective troposphere and the radiatively controlled stratosphere with air masses showing chemical and dynamical properties of both ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The Paleocene-Eocene Thermal Maximum (PETM; ∼55.9 Ma) was a hyperthermal event associated with large carbon cycle perturbations, sustained global warming, and marine and terrestrial environmental changes. One possible ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Changing conditions of the climate and underlying surface have altered the rainfall-runoff relationships in many basins, greatly increasing additional challenges in the applicability of hydrological models for studying the ...
-
(Master thesis / Masteroppgave, 2019)The inner Oslofjord has undergone many changes in ecological quality throughout time. The Vestfjorden Avløpsselskap (VEAS) wastewater treatment plant has been involved in these changes with a generally positive effect. ...
-
(Master thesis / Masteroppgave, 2020)Stratigraphic profiles of two sediment cores stationed at Loperen are analyzed to distinguish temporal changes of accumulation rates of total organic carbon (TOC) in at least the last four centuries. The aim is to investigate ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Donjek Glacier has an unusually short and regular surge cycle, with eight surges identified since 1935 from aerial photographs and satellite imagery with a ~12 year repeat interval and ~2 year active phase. Recent surges ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Acquiring data to analyse change in topography is often a costly endeavour requiring either extensive, potentially risky, fieldwork and/or expensive equipment or commercial data. Bringing the cost down while keeping the ...
-
(Master thesis / Masteroppgave, 2010)This thesis provides an assessment of the application of terrestrial LiDAR for rock mass characterisation and support design in drill and blast tunnels. The study includes establishing an appropriate work-flow for data ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Snow cover is one of the crucial factors influencing the plant distribution in harsh Arctic regions. In tundra environments, wind redistribution of snow leads to a very heterogeneous spatial distribution which influences ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)China is the largest agricultural country with the largest population and booming socio-economy, and hence, remarkably increasing water demand. In this sense, it is practically critical to obtain knowledge about spatiotemporal ...
-
(Master thesis / Masteroppgave, 2008)Oppgaven undersøker bruk av flytalgoritmer for skredforskning, med spesielt fokus på steinskred. Flytalgoritmer er i utgangspunkt et velbeskrevet fenomen innenfor hydrologien, så inspirasjon hentes fra dette fagfeltet. En ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)We provide an independent test for the proposed pre-breakup fits between the South American and African continental margins based on new palaeomagnetic data. In the course of modelling the opening of the South Atlantic ...

(Master thesis / Masteroppgave, 2021)
-
(Master thesis / Masteroppgave, 2023)Denne masteroppgaven tar for seg bruk av modellverktøy for dimensjonering av steinspranggjerder mot steinsprang. Målet med oppgaven er å kartlegge utvalgte modellverktøys egnethet, samt hvilken betydning valg av av disse ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Earth system models (ESMs) are our primary tool for projecting future climate change, but their ability to represent small-scale land surface processes is currently limited. This is especially true for permafrost landscapes ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)In permafrost areas, seasonal freeze-thaw cycles result in upward and downward movements of the ground. For some permafrost areas, long-term downward movements were reported during the last decade. We measured seasonal and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Industrial contaminants accumulated in Arctic permafrost regions have been largely neglected in existing climate impact analyses. Here we identify about 4500 industrial sites where potentially hazardous substances ...
