-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Seismic reflection data along volcanic passive margins frequently provide imaging of strong and laterally continuous reflections in the middle and lower crust. We have completed a detailed 2‐D seismic interpretation of the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)A comprehensive monitoring program is an integral part of the safe operation of geological CO2 storage projects. Noble gases can be used as geochemical tracers to detect a CO2 anomaly and identify its origin, since they ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)We present new structural, geochemical and U–Pb zircon data from syn- to late-orogenic sedimentary–volcanic basins in the southwestern part of the Trondheim Nappe Complex, central Norwegian Caledonides. In this area, a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Transpressional uplift domains of inverted Pliocene–Pleistocene basin fill along the San Andreas fault zone in Coachella Valley, southern California (USA), are characterized by fault linkage and segmentation and deformation ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The high-pressure metamorphic Nevado-Filábride Complex (NFC) in the Betics mountain range of southeastern Spain exhibits continental and ocean-derived tectonic units, which are key for understanding the geodynamic evolution ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)This paper considers the lithospheric structure and evolution of the wider Barents–Kara Sea region based on the compilation and integration of geophysical and geological data. Regional transects are constructed at both ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Over the past 15 yr, numerical models of convection in Earth’s mantle have made a leap forward: they can now produce self-consistent plate-like behaviour at the surface together with deep mantle circulation. These digital ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Fluid-pressure cycles are commonly invoked to explain alternating frictional and viscous deformation at the base of the seismogenic crust. However, the stress conditions and geological environment of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Northern Israel was struck during July 2018 by a ML4.4 earthquake followed by a seismic sequence that lasted about 30 days. This seismic sequence occurred in the center of a temporary seismic network deployed around the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The Forlandsundet Graben, situated along the NE Atlantic continental margin in the western Svalbard archipelago in Arctic Norway, represents a unique opportunity to study a basin that evolved along an obliquely rifted ...
-
(Master thesis / Masteroppgave, 2005)Combination of field studies and analytical techniques provides the basis for unravelling the tectonic evolution of the continental crust. Here field studies together with the ID-TIMS method for U/Pb-dating have been applied ...
-
(Master thesis / Hovedoppgave, 2004)The Caledonian Orogen in East Greenland comprises an autochthonous basement complex overlain by a Late Proterozoic to Early Proterozoic cover sequence with a regionally extensive thrust sheet complex on top. The thrust ...
-
(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 ...
-
(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, 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 ...
-
(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 ...
