Geology, geochemistry and geochronology of Neoproterozoic rocks in western Shire, Northern Ethiopia (Master thesis / Masteroppgave, 2014)Based on the integration of U-Pb isotopic data, geochemical data, petrographic data and geological data of the Neoproterozoic granitic and metavolcanic rocks of southernmost ANS, Northern Ethiopia, western shire district, ...
-
(Master thesis / Masteroppgave, 2015)Different horizons within an exposed deformed sedimentary sequence can, along with the fracture pattern, potentially be utilized by reducing fluids, in turn altering the mineralogical composition of the unit. Potentially ...
-
(Master thesis / Masteroppgave, 2015)This study is a small part of ongoing research for CO2 sequestration at Longyearbyen CO2 Storage Lab, Svalbard, Norway. The primary aim of this study is to determine geomechanical properties of two important caprock units ...

(Master thesis / Masteroppgave, 2015)Denne oppgaven tar for seg flom- og jordskredhendelser i Valdres, langs Randsfjorden og fylkesveiene i Etnedalen, på Østlandet. Begrepene jordskred og flomskred skaper uklarheter ved utførelse av fare- og risikoanalyser i ...
-
(Master thesis / Masteroppgave, 2013)The following thesis is the culmination of a two year study on Svalbard, an archipelago located in the high Arctic. The main purpose of this thesis is to investigate the presence of a karst lake system and its implications ...

Geotechnical and geophysical investigations for stability assessment; A case study at Hvittingfoss, Southern NorwayRestricted Access (Master thesis / Masteroppgave, 2014)
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2009)An evaluation of rock slide tsunami hazard is applied to all Norwegian lakes larger than 0.1 km2 based on their topographical setting. The analysis results in a topographic rock slide potential score that indicates the ...
-
(Master thesis / Masteroppgave, 2021)Glacial lakes are an important component of terrestrial meltwater storage and respond to climate change and glacier retreat. Although there is evidence of rapid worldwide growth of glacial lakes, changes in frequency and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The thick sequence of Quaternary sediments preserved within the northern North Sea contains important information about the glacial history, palaeo-oceanographic conditions and slope stability of this region during the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Glacial-isostatic adjustment (GIA) is the key process controlling relative sea-level (RSL) and paleo-topography. The viscoelastic response of the solid Earth is controlled by its viscosity structure. Therefore, the appropriate ...
-
(Chapter / Bokkapittel / AcceptedVersion, 2021)Retreating glaciers and thawing permafrost are causing local- to regional-scale hazards that threaten lives and livelihoods, infrastructure, sustainable resource development, and national security. Permafrost hazards are ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)In this study, we assess glacier area and length changes in mainland Norway from repeat Landsat TM/ETM+-derived inventories and digitized topographic maps. The multi-temporal glacier inventory consists of glacier outlines ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The volume of glaciers in Iceland (∼3,400 km3 in 2019) corresponds to about 9 mm of potential global sea level rise. In this study, observations from 98.7% of glacier covered areas in Iceland (in 2019) are used to construct ...
-
(Doctoral thesis / Doktoravhandling, 2011)Ice loss from glaciers and ice caps in the Arctic constitute a major contribution to eustatic sea-level rise. Climate change is more pronounced in the Arctic than in other regions, because strong feedback mechanisms such ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Glacier mass balance in Norway is only observed over a small portion (15%) of the glacierized surface and only for short time periods (10 years) for most sites. To provide a comprehensive overview of the temporal mass-balance ...
