(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The creation of new fractures during an earthquake produces rock damage and contributes to the dissipation of strain energy. During dynamic rupture propagation, tensile microfractures can form in the earthquake process ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Seismic faulting causes wall rock damage, which is driven by both mechanical and thermal stress. In the lower crust, co-seismic damage increases wall rock permeability, permits fluid infiltration and triggers metamorphic ...

Natural abundance isotope ratios to differentiate sources of carbon used during tumor growth in vivo (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Background Radioactive or stable isotopic labeling of metabolites is a strategy that is routinely used to map the cellular fate of a selected labeled metabolite after it is added to cell culture or to the ...

Natural neutralization of acid mine drainage: A possible remedial measure for the Folldal and Sulitjelma mines?Restricted Access (Master thesis / Masteroppgave, 2017)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)According to the European Water Framework Directive (WFD), restoration actions are needed if the present-day ecological quality status (EcoQS) is worse than good. However, less stringent environmental objectives may be ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Several mechanisms have been suggested as drivers of naturally occurring underpressure. However, the phenomenon is largely underrepresented in literature. Previous studies have focused on individual cases in North America, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The NE Atlantic region and its continental margins (Fig. 1) hold unique information for understanding many aspects of Earth science, from global geodynamics to palaeoceanography and global environmental change. It also ...
-
(Doctoral thesis / Doktoravhandling, 2021)Carbon capture and storage (CCS) is a relatively new technology that captures CO2 before it reaches the atmosphere and safely stores it underground. CO2 storage will achieve significant climate change mitigation, only if ...
-
Near-surface temperatures and potential for frost weathering in blockfields in Norway and Svalbard (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Blockfields remain enigmatic regarding their origin, internal structure, surface processes, and glaciological implications. In Scandinavia, blockfields are found on high-elevation, low-relief mountains (plateaus) across ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The stable carbon isotopic compositions of carbonate sediments (δ13Ccarb) have been widely used to reconstruct the global carbon cycle and as a stratigraphic correlation tool. This work investigates a δ13Ccarb record of ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)Quartz porphyry of rhyolitic composition though a volumetrically minor is an important component of metavolcanic successions in the Gadag schist belt in the western Dharwar craton. The quartz porphyries are calc-alkaline, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)During the late Neogene, global climate underwent a long-term transition to cooler climates that culminated in the Quaternary icehouse conditions. In the East Asian terrestrial realm, atmospheric dustiness increased, and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)A rare gemstone form of “ekanite” from Okkampitiya, eastern Sri Lanka, has a chemical composition of Ca2Th0.9U0.1Si8O20, corresponding to that of the tetragonal mineral ekanite. The Okkampitiya material, however, has ...
-
(Doctoral thesis / Doktoravhandling, 2019)In the Late Neoproterozoic the supercontinent Rodinia started to disintegrate, and the continents Baltica and Laurentia began to rift apart to form the Iapetus Ocean. Early stages of subsidence caused by ductile stretching ...

(Master thesis / Masteroppgave, 2018)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The Sea of Galilee in northeast Israel is a freshwater lake filling a morphological depression along the Dead Sea Fault. It is located in a tectonically complex area, where a N-S main fault system intersects secondary fault ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Two nested clinoform set types of different scales and steepness are mapped and analysed from high‐resolution seismic data. Restoration of post‐depositional faulting reveals a persistent pattern of small‐scale, high‐angle ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Understanding fluid flow in rocks is crucial to quantify many natural processes such as ground water flow and naturally triggered seismicity, as well as engineering questions such as displacement of contaminants, the ...
-
(Master thesis / Masteroppgave, 2017)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In applications of climate information, coarse-resolution climate projections commonly need to be downscaled to a finer grid. One challenge of this requirement is the modeling of subgrid variability and the spatial and ...
