(Master thesis / Masteroppgave, 2011)To identify possible protosources for the Asker Group 573 in situ LA-MC-ICPMS uranium-lead and 509 lutetium-hafnium analyses were performed on detrital zircon grains from seven samples. The samples from the Kolsås and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Detrital zircon U–Pb geochronology and heavy mineral data from four main rivers in coastal southern Tanzania - the Rufiji, Matandu, Mbwemkuru and Ruvuma rivers - are compared with the bedrock geology of their catchment and ...
-
(Master thesis / Masteroppgave, 2022)The number of discovered exoplanets reached five thousand, and it allows scientists to look not only at individual planets’ occurrence trends but start to analyse multi-planet systems in a statistical sense. In this thesis, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Ranking of CO2 storage sites in the Nordic countries has previously been reported from the NORDICCS project. The ranking was based on geological characteristics of reservoir and seal, data coverage and safety evaluation ...
-
(Doctoral thesis / Doktoravhandling, 2011)Glaciers, ice caps and ice sheets constitute a large reservoir in the global hydrological cycle and provide a coupling between climate and sea-level. Observations of glacial change is important for constraining their ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The formation of the NE Atlantic conjugate margins is the result of multiple rifting phases spanning from the Late Paleozoic and culminating in the early Eocene when breakup was accompanied with intense magmatic activity. ...

Quantification of physical vulnerability to landslides : A case study in Buzǎu County, RomaniaRestricted Access (Master thesis / Masteroppgave, 2012)Physical vulnerability is a key parameter in risk estimation. It defines the level of damage given that the hazard is realized, and hence translates hazard levels into risk levels. The quantitative assessment of vulnerability ...
-
(Master thesis / Masteroppgave, 2023)A number of studies have shown that the boreal forest in North America has experienced a nearly two-fold increase in burned area over the past 60 years, with a corresponding rise in the number of large fires. Permafrost ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)This study focuses on a quantitative multi-source uncertainty analysis of multi-model predictions. Three widely used hydrological models, i.e., Xinanjiang (XAJ), hybrid rainfall–runoff (HYB), and HYMOD (HYM), were calibrated ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)In a climate model, surface energy and water fluxes of the vegetated ecosystem largely depend on important structural attributes like leaf area index and canopy height. For forests, management can greatly alter these ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Every spring the mechanical river ice break-up and associated ice-runs or flooding pose a threat to communities at Northern latitudes. Monitoring and mitigation efforts along remote Arctic rivers are possible but logistically ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Abstract. Snow cornices develop along mountain ridges, edges of plateaus, and marked inflections in topography throughout regions with seasonal and permanent snow cover. Despite the recognized hazard posed by cornices in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Climate change and anthropogenic interventions have obviously altered the eco-hydrological regimes. A quantitative evaluation and attribution of the eco-hydrological alterations are urgently required. ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)As a large open lake that connects to the lower Yangtze River, the Poyang Lake, China, has persisted dramatic water level decline since 2003. For better management of lake water resources and ecosystem, this study ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Shallow aseismic creep is a key deformation component along plate boundaries that contributes to the energy budget during the seismic cycle. Several major active continental faults show spatial alternation of creeping and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract The economic impacts of climate change are highly uncertain. Two of the most important uncertainties are the sensitivity of the climate system and the so-called damage functions, which relate climate ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Sampling strategies used in paleomagnetic studies play a crucial role in dictating the accuracy of our estimates of properties of the ancient geomagnetic field. However, there has been little quantitative analysis ...
-
(Doctoral thesis / Doktoravhandling, 2020)Modern seismic exploration for hydrocarbons in the subsurface relies on a good understanding of how different rock properties influence the remotely recorded seismic response. The bridge between the geological properties, ...
-
(Master thesis / Masteroppgave, 2021)Debris flows can travel long distances and at high speeds. This makes them destructive. Large parts of Norway are exposed to debris flow hazards. Roads and railways are particularly exposed as well as affected infrastructure. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)A defining characteristic of the recent geomagnetic field is its dominant axial dipole which provides its navigational utility and dictates the shape of the magnetosphere. Going back through time, much less is known about ...
