(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Stochastic modeling is often employed in environmental sciences for the analysis and understanding of complex systems. For example, random fields are key components in uncertainty analysis or Bayesian inverse modeling. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract. The Arctic is very susceptible to climate change and thus is warming much faster than the rest of the world. Clouds influence terrestrial and solar radiative fluxes and thereby impact the amplified Arctic warming. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Cone-in-cone (CIC) and beef (BF) carbonate lenses ornament detachment zone faults underlying Triassic growth basins on Edgeøya. Field relationships place CIC and BF growth as during early diagenesis and a transition from ...

Conodonter og avsetningsmiljø av den midtre og øvre kambriske alunskiferen, Slemmestad, Oslofeltet. (Master thesis / Masteroppgave, 2014)En masteroppgave som tar for seg mikrofossilanalyse med fokus på conodonter i tillegg til avsetningsmiljø basert mikrofacies-analyser.
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Infrastructure built on perennially frozen ice-rich ground relies heavily on thermally stable subsurface conditions. Climate-warming-induced deepening of ground thaw puts such infrastructure at risk of failure. For better ...

(Master thesis / Masteroppgave, 2019)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Rapid warmings epitomize the Dansgaard-Oeschger events that are recorded in Greenland ice cores and imprinted in ocean sediment cores. While the abrupt climate changes appear connected to perturbations in sea ice and ocean ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Radioisotopic dating of volcanic minerals is a powerful method for establishing absolute time constraints in sedimentary basins, which improves our understanding of the chronostratigraphy and evolution of basin processes. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Robust projections of changes in the hydrological cycle in a non-stationary climate rely on trustworthy estimates of the water balance elements. Additional drivers than precipitation and temperature, namely wind, radiation, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Mantle viscosity controls a variety of geodynamic processes such as glacial isostatic adjustment (GIA), but it is poorly constrained because it cannot be measured directly from geophysical measurements. Here we develop a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Land-use changes until the beginning of the 20th century made the terrestrial biosphere a net source of atmospheric carbon. Later, burning of fossil fuel surpassed land use changes as the major anthropogenic source of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Estimates of the relative motion between the Hawaiian and Louisville hot spots have consequences for understanding the role and character of deep Pacific‐mantle return flow. The relative motion between these primary hot ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Although partial melt in the asthenosphere is important geodynamically, geophysical constraints on its abundance remain ambiguous. We use a database of seamounts detected using satellite altimetry to constrain the temporal ...

CONTAMINATION OF GROUNDWATER DUE TO THE MINERAL PROCESSING LAYER IN FOLLDAL MINE WITH FIELD MEASUREMENTS AND LABORATORY EXPERIMENTSRestricted Access (Master thesis / Masteroppgave, 2017)
-
(Master thesis / Masteroppgave, 2012)A total of seventy reservoir core samples from nine wells of the Mid-Norway and the Barents Shelf were geochemically analyzed to compare the composition, alteration effects, maturation and organic facies. The analytical ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Antarctica has traditionally been considered continental inside the coastline of ice and bedrock since Press and Dewart (1959). Sixty years later, we reconsider the conventional extent of this sixth continent. Geochemical ...
-
(Doctoral thesis / Doktoravhandling, 2019)This study presented in this doctoral thesis addresses the development of the Upper Jurassic Curtis Formation, outcropping in east-central Utah. The study suggests a separation of the Curtis Formation in three geological ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)We present three-dimensional numerical models to investigate the dynamics of continental collision, and in particular what happens to the subducted continental lithosphere after oceanic slab break-off. We find that in some ...
-
(Master thesis / Masteroppgave, 2016)Several studies have been conducted since last 50 years to understand the crustal architecture of the passive margins. The conjugate passive margins along Indian Ocean are very less surveyed and studied due to geographical ...
