(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Climate model studies of the consequences of solar geoengineering are central to evaluating whether such approaches may help to reduce the harmful impacts of global warming. In this study we compare the sunshade solar ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Key observational indicators of climate change in the Arctic, most spanning a 47 year period (1971–2017) demonstrate fundamental changes among nine key elements of the Arctic system. We find that, coherent with increasing ...

(Chapter / Bokkapittel / AcceptedVersion; Peer reviewed, 2020)The 4D/5D interpolation and regularization methods effectively improve the quality of seismic imaging. In addition to the Fourier domain interpolation method, 5D interpolation based on the common reflection surface (CRS) ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Glacier surges are periodic episodes of mass redistribution characterized by dramatic increases in ice flow velocity and, sometimes, terminus advance. We use optical satellite imagery to document five previously ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)A combined experimental and numerical study was undertaken to better understand the spatial distribution of secondary mineral growth along a basalt column. The work demonstrated that few and large crystals formed at random ...
-
(Master thesis / Hovedoppgave, 2007)Formålet med oppgaven har vært å finne ut hvorvidt topografiske parametre kan gi et nyttig bidrag til vegetasjonskartleggingen i norske fjellandskap. Det har vært forsøkt å finne ut om vegetasjonsmønsteret styres av ...
-
(Master thesis / Masteroppgave, 2005)Abstract This thesis concerns certain aspects of the production of CCN. In-cloud oxidation followed by cloud droplet evaporation is an important chemical process where sulfate is produced, and only particles with radii ...
-
(Master thesis / Masteroppgave, 2005)Oppgavens målsetting er å analysere den relative påvirkning naturressursene hadde for hvordan Kongo-krigen oppstod og utviklet seg. Den Demokratiske Republikken Kongo (DRK) er et av verdens mest naturressurs rike land, men ...
-
(Master thesis / Hovedoppgave, 2005)Vassdragene er en verdifull ressurs for mange ulike brukerinteresser, og utgjør livsnerven i en mangfoldig vassdragsnatur. Å forvalte Norges særegne vassdragsmiljø, er en kompleks og utfordrene oppgave som innebærer bred ...
-
(Master thesis / Masteroppgave, 2023)Flere av de tettest bebodde områdene i Norge har kvikkleire i grunnen. Økende tilflytting til disse områdene vil medføre et økt behov for kvikkleirekartlegging. Konsekvensene av kvikkleireskred kan potensielt bli svært ...
-
(Master thesis / Masteroppgave, 2012)I denne oppgaven er potensialet til L-band differensiell interferometrisk SAR (DInSAR) evaluert med hensyn til å detektere ustabile helninger i områder med vanskelige topografiske og klimatiske forhold. I hvilke områder ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)The presence of hydrothermal rutile enables the dating of mineralization related to hydrothermal processes. Refinement of the laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) technique is key to ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The mechanical integrity of caprocks overlying injection formations is one of the key factors for safe storage of carbon dioxide in geological formations. Undrained effects caused by CO2 injection on strength and elastic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The mechanics of magma emplacement in the Earth's crust corresponds to the flow of a viscous fluid into a deforming solid. The Earth's crust through which magma is emplaced is visco-elasto-plastic, and field observations ...

(Master thesis / Masteroppgave, 2014)Magma transport in volcanic plumbing systems induces surface deformation, which can be monitored by geodetic techniques, such as GPS and InSAR. These geode- tic signals are commonly analyzed through geodetic models in order ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The mean drift in a permeable homogeneous bottom layer caused by internal gravity waves in an overlying stratified fluid, is investigated theoretically. We apply a Lagrangian formulation, together with the long-wave ...
