(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Abstract The Radar Imager for Mars’ Subsurface Experiment (RIMFAX) is a Ground Penetrating Radar on the Mars 2020 mission’s Perseverance rover, which is planned to land near a deltaic landform in Jezero crater. RIMFAX ...
-
(Master thesis / Masteroppgave, 2005)The human influence on vegetation causes changes in the surface reflective properties. By using MODIS land cover and MODIS surface albedo products, an estimation of radiative forcing due to surface albedo changes caused ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)We report on the AeroCom Phase II direct aerosol effect (DAE) experiment where 16 detailed global aerosol models have been used to simulate the changes in the aerosol distribution over the industrial era. All 16 models ...

-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)Rainfall-induced landslide susceptibility assessment is currently considered an effective tool for landslide hazard assessment as well as for appropriate warning and forecasting. As part of the assessment procedure, a ...
-
Rainfall–Runoff Processes and Modelling in Regions characterized by Deficiency in Soil Water Storage (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The partial runoff is complicated in semi-arid and some semi-humid zones in terms of what the runoff generates in partial vertical positions. The partial runoff is highlighted by horizontal soil heterogeneity as well. How ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract Increases in ocean temperatures in the Filchner Ronne region of Antarctica are likely to result in increased ice mass loss and sea level rise. We constrain projections of the 21st century sea level contribution ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The Paleocene–Eocene Thermal Maximum (PETM; ∼ 55.9 Ma) was a period of rapid and sustained global warming associated with significant carbon emissions. It coincided with the North Atlantic opening and emplacement of the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Thicker snow cover in permafrost areas causes deeper active layers and thaw subsidence, which alter local hydrology and may amplify the loss of soil carbon. However, the potential for changes in snow cover and surface ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract We explore drivers of variability in the Norwegian Atlantic Slope Current, which carries relatively warm Atlantic Water towards the Barents Sea and Arctic Ocean, using CMEMS satellite altimetry data and TOPAZ4 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Marine outlet glaciers on Greenland are retreating, yet it is unclear if the recent fast retreat will persist, and how atmosphere and ocean warming will impact future retreat. We show how a marine outlet glacier in ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract. With the EU-funded PACE (Permafrost and Climate in Europe) project at the turn of this century, several deep boreholes (100 m+) were drilled in European mountain sites, including in mainland Norway, Svalbard and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The incomplete understanding of glacier dynamics is a major source of uncertainty in assessments of sea-level rise from land-based ice. Through increased ice discharge into the oceans, accelerating glacier flow has the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The important marker species for the base of the Jurassic, Cerebropollenites thiergartii, occurs contemporaneously with at least nine related taxa. However, their distinction is difficult and has been confused in the past. ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Field observations and geophysical data reveal a causal link between brittle seismic failure and eclogitization of the lower continental crust. We present results from experimental deformation of plagioclase-rich samples ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Peridotites of Ulten Zone (Eastern Alps, N Italy) show a transition from coarse protogranular spinel lherzolites to fine-grained amphibole + garnet peridotites, recorded by the crystallization of garnet coronas around ...
-
(Master thesis / Masteroppgave, 2016)This master project focuses on the mineralogical changes and re-distribution of S between apatite, monazite and scapolite in the Lindås Nappe, Bergen Arcs, W-Norway. The assemblage developed during the Sveconorwegian ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Fluid flow in crystalline rocks in the absence of fractures or ductile shear zones dominantly occurs by grain boundary diffusion, as it is faster than volume diffusion. It is, however, unclear how reactive fluid ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract The Rosebank field, located in the Faroe-Shetland Basin, contains producible hydrocarbons in intra-basaltic siliciclastic reservoirs. The volcanic-reservoir interface is poorly studied and the geochemical system, ...
-
(Master thesis / Masteroppgave, 2007)Abstract Mineralogical and chemical analysis of alum shale and black shale samples were done using the XRD, XRF, sulfur chemical analysis, petrographic and scanning electron microscopy. Samples from two study areas in the ...
