(Doctoral thesis / Doktoravhandling, 2017)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The Ottfjället Dyke Swarm (ODS) is a prominent component of the Ediacaran mafic magmatism associated with opening of the Iapetus ocean, and hosted in the Särv Nappe, Middle Allochthon of the Scandinavian Caledonides. A ...

(Doctoral thesis / Doktoravhandling, 2012)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The development of the Oslo Rift started in the latest Carboniferous in the northern foreland of the Variscan Orogen. The initial, intensive, and mainly mafic magmatism at around 300 Ma, was followed by a period of some ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Uncertainty of best management practice (BMP) effectiveness is an important factor in the development of watershed management plans. This study explored the uncertainty of BMP effectiveness in reducing total nitrogen (TN) ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)This study investigates the limitation of simplified stress path assumptions, particularly uniaxial strain conditions, in fault stability assessments for CO2 injection sites. We conducted a 3D geomechanics simulation for ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)The underexplored Barents shelf petroleum province is a globally unique example where naturally occurring underpressure is observed offshore and onshore. In the offshore parts of the northern Barents shelf, minor underpressure ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Current experimental approaches on faults provide a significant contribution to our understanding of brittle deformation in the crust. However, they rarely present a multiscale view of fault initiation, propagation and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The Grande da Pipa River (GPR) basin (Portugal) has natural conditions that favor the occurrence of landslides. The hydrological year 2009/10 was characterized by high amounts of rainfall, which led to the occurrence of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The Ordovician global cooling trend observed by several temperature proxies, which coincides with one of the most significant evolutionary diversifications on Earth, is yet to be fully understood. This study presents new ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The sizes and shapes of ice crystals influence the radiative properties of clouds, as well as precipitation initiation and aerosol scavenging. However, ice crystal growth mechanisms remain only partially characterized. We ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Abstract Introductory practical work in university physics degrees is dominated by highly constrained and instructions-based tasks with limited value for developing students’ scientific and critical thinking ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)To help understand volcanic facies in the subsurface, data sets that enable detailed comparisons between down-hole geophysical data and cored volcanic intervals are critical. However, in many cases, the collection of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract. The representation of snow processes in most large-scale hydrological and climate models is known to introduce considerable uncertainty into the predictions and projections of water availability. During the ...
-
(Master thesis / Hovedoppgave, 2005)Fjellskred i Norge har hatt fatale konsekvenser i historisk tid. Kartlegging, undersøkelser og overvåkning av potensielt rasfarlige områder er viktig siden vi vet at nye fjellskred vil komme. I denne oppgaven gjøres ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Albedo is a fundamental parameter in earth sciences, and many analyses utilize the Moderate Resolution Imaging Spectroradiometer (MODIS) bidirectional reflectance distribution function (BRDF)/albedo (MCD43) algorithms. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract. The mid-Pliocene warm period (3.264–3.025 Ma) is the most recent geological period in which the atmospheric CO2 concentration was approximately equal to the concentration we measure today (ca. 400 ppm). Sea surface ...
-
(Master thesis / Masteroppgave, 2005)Seepage and slope stability issues concerning infiltration in unsaturated slopes are investigated and presented. 2-D finite element analyses are used to study the effects of the different hydraulic characteristics of a ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)In 3D marine seismic acquisition, the seismic wavefield is not sampled uniformly in the spatial directions. This leads to a seismic wavefield consisting of irregularly and sparsely populated traces with large gaps between ...
