(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)In this study we assess the present-day gas hydrate stability zone for the Barents Sea and Kara Sea region. Thereby, we make use of a data-based 3D lithosphere-scale pressure and thermal model. The resulting gas hydrate ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)The hydrological regimes of downstream reservoirs have been significantly altered due to the operation and regulation of upstream cascade reservoirs. The original design flood quantiles, namely “design flood in construction ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)In this paper we describe and summarize the main achievements of the European Aerosol Cloud Climate and Air Quality Interactions project (EUCAARI). EUCAARI started on 1 January 2007 and ended on 31 December 2010 leaving a ...

(Master thesis / Masteroppgave, 2017)Alum- and black shales are lithologies rich in sulphides and trace elements including uranium, and may pose harm to the environment during weathering. Acidification of surface- and groundwater and swelling may occur. During ...
-
(Master thesis / Masteroppgave, 2005)The aim of this study is to compare oils from known biodegraded fields offshore Norway to waxes and oils from an artificial cavern storage facility, to determine if the oil degradation processes observed in natural reservoirs ...

(Master thesis / Masteroppgave, 2015)The main objective of this study is to attempt to correlate twelve (12) core and (1) one outcrop source rock samples, recovered from the Hammerfest Basin, the Nyslepp/Måsøy Fault Complex, the Finnmark Platform, the Nordkapp ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The Freetown Layered Complex (FLC) is a massive mafic layered intrusion cropping out along the coast of Sierra Leone. The present combined geochemical and geochronological (40Ar/39Ar on plagioclase: 201·7 ± 0·7 and 202·3 ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The spectacular Lusi mud-eruption started in northeast Java the 29th of May 2006. Despite extensive research, the origin of the erupted water remains elusive and poorly constrained. Here we present a comprehensive study ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The Peräpohja belt comprises a greenschist to amphibolite facies; multiply-folded supracrustal sequence of quartzites; mafic volcanics; carbonate rocks; black shales; mica schists and greywackes deposited from ca. 2.44 Ga ...

(Master thesis / Masteroppgave, 2007)Glaciers and ice masses are very important components of the earth system both in terms of global water storage and as climate indicators. The amount of water tied up in glaciers and ice caps is equivalent to about 69 ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Today's geodynamic models can, often do and sometimes have to become very complex. Their underlying, increasingly elaborate numerical codes produce a growing amount of raw data. Post-processing such data is therefore ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)We present geodynamic models featuring mantle plumes that are almost exclusively created at the margins of large thermo‐chemical piles in the lowermost mantle. The models are based on subduction locations and fluxes inferred ...
-
(Doctoral thesis / Doktoravhandling, 2016)In plate tectonics scientists study the present and past motions of the lithospheric plates over the Earth’s surface. The reconstruction of the location and orientation of the continents and oceans in deep time is referred ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)We present the first thermal model for the lithosphere in Turkey, which shows a highly heterogeneous pattern associated with mosaics of the Tethyan and modern subduction systems. We calculate a regionally average crustal ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In the oil and gas industry, during exploration prospect assessment, explorationists rely on ad hoc manual work practices and tools for developing and communicating multiple hypothetical geological scenarios of the prospect. ...
