(Master thesis / Masteroppgave, 2018)Debris flows and debris avalanches represent a large threat to society in Norway. The intensity and frequency of these events is expected to increase over the course of the next 50 years due to changing precipitation ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)The backwater effect (i.e. adjustments in open-channel flow as a response to proximity of standing water) is used to predict down-dip changes in morphodynamics and consequent sediment distribution on fluvial systems. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)An operational ocean and sea ice forecast model, Barents-2.5, is implemented for short-term forecasting at the coast off northern Norway, the Barents Sea, and the waters around Svalbard. Primary forecast parameters are sea ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Abstract The deformation radius is widely used as an indication of the eddy length scale at different latitudes. The radius is usually calculated assuming a flat ocean bottom. However, bathymetry alters the baroclinic modes ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Engabreen is an outlet glacier of the Svartisen Ice Cap located in Northern Norway. It is a unique glacier due to the Svartisen Subglacial Laboratory which allows direct access to the glacier bed. In this study, we combine ...
-
(Doctoral thesis / Doktoravhandling, 2019)The main objectives of this thesis were to study basalt alteration and formation of secondary phases and their implications on Mars (Paper I), and potential consequences for petroleum reservoirs influenced by the presence ...
-
(Master thesis / Masteroppgave, 2010)Most maps and publications dealing with the geology of the Bodø-Sulitjelma area have postulated the presence of a major basement culmination; the “Heggmovatn basement dome” between Bodø and Fauske. Granitic gneisses and ...
-
Basement structure and its influence on the structural configuration of the northern North Sea rift (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The northern North Sea rift basin developed on a heterogeneous crust comprising structures inherited from the Caledonian orogeny and Devonian postorogenic extension. Integrating two‐dimensional regional seismic reflection ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Extensional processes can lead to complex crustal configuration depending on the mechanisms of lithospheric thinning and the impact of magmatic additions during rifting and breakup. In this context, we studied the Vøring ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)The SW Barents Sea is an epicontinental platform consisting of N- to NNE-oriented basins separated by basement highs. The basins were formed during four distinct rift-phases in the Carboniferous, Late Permian, Late ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Igneous sills are common components in rifted sedimentary basins globally. Much work has focused on intrusions emplaced at relatively shallow palaeodepths (0 – 1.5 km). However, owing to constraints of seismic reflection ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Empirical glacier mass-balance models are commonly used in assessments of glacier and runoff evolution. Recent satellite-borne geodetic mass-balance observations of global coverage facilitate large-scale model calibration ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2006)A method for assimilating remotely sensed snow covered area (SCA) into the snow subroutine of a grid distributed precipitation-runoff model (PRM) is presented. The PRM is assumed to simulate the snow state in each grid ...
-
(Doctoral thesis / Doktoravhandling, 2021)Benthic foraminifera are microscopically small organisms living in marine sediments where they live in tiny little houses also known as tests. Foraminifera respond rapidly to environmental changes and as many of their tests ...
-
(Master thesis / Masteroppgave, 2006)An intense extratropical storm, named Erwin/Gudrun, over the North Atlantic during winter 2005 is investigated to determine atmospheric factors contributing to its development. WRF is the numerical model which has been ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Abstract. Understanding components of the total streamflow is important to assess the ecological functioning of rivers. Binary or two-component separation of streamflow into a quick and a slow (often referred to as baseflow) ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Abstract. Anthropogenic aerosol emissions have increased considerably over the last century, but climate effects and quantification of the emissions are highly uncertain as one goes back in time. This uncertainty is partly ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)The use of aqueous film-forming foams (AFFFs) has resulted in hot spots polluted with poly- and perfluorinated alkyl substances (PFASs). The phase out of long-chained perfluoroalkyl acids (PFAAs) from AFFFs resulted in the ...
-
Biochar Effect on Maize Yield and Soil Characteristics in Five Conservation Farming Sites in Zambia (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Biochar addition to agricultural soils can improve soil fertility, with the added bonus of climate change mitigation through carbon sequestration. Conservation farming (CF) is precision farming, often combining minimum ...
-
(Master thesis / Hovedoppgave, 2004)The spring flood is a multivariate event that can be characterized by the floodcharacteristics peak discharge, duration and volume. Traditionally these flood characteristics have been modelled separately, but by modelling ...
