(Master thesis / Masteroppgave, 2018)The goal of this thesis is to estimate the amount of extension and displacement across faults using geometrical constraints. The mapped area is dominated by middle Ordovician to lower Silurian sediments folded during the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Glacial lakes are an important and dynamic component of terrestrial meltwater storage, responding to climate change and glacier retreat. Although there is evidence of rapid worldwide growth of glacial lakes, changes in ...
-
(Master thesis / Masteroppgave, 2023)The S1 (Sentinel 1) and S2 (Sentinel 2) missions use high-resolution satellite imagery to map the land surface over large swaths. With a minimum 5-day and 6-day repeat time, imagery over earths land can be quickly obtained ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract During the RESOLVE project (“High‐resolution imaging in subsurface geophysics: development of a multi‐instrument platform for interdisciplinary research”), continuous surface displacement and seismic array ...
-
(Doctoral thesis / Doktoravhandling, 2017)Advances and retreats of mountain glaciers in Arctic and alpine areas are one of the most visible signs of climatic changes. Glaciers therefore play an important role as sensitive climate change indicators. Glacier products ...

-
(Master thesis / Masteroppgave, 2007)Abstract This study uses multispectral Landsat satellite imagery and a high resolution Digital Elevation Model based on 1990/95 aerial stereoimagery (Norwegian Polar Institute) to map moraines and glacier terminus positions ...
-
(Master thesis / Masteroppgave, 2011)Det finnes mye skredutsatt infrastruktur i Norge, og det er et behov for kartlegging av skredbaner ved lokaliteter hvor man kjenner til at det regelmessig går skred. Dette både for bedre å kunne vurdere snøskredfaren i ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)A layer of debris cover often accumulates across the surface of glaciers in active mountain ranges with exceptionally steep terrain, such as the Andes, Himalaya, and New Zealand Alps. Such a supraglacial debris layer has ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The evaluation of the interplay between kerogen maturation and total organic carbon (TOC) content within an organic-rich shale is critical to characterizing source rock shale's elastic behavior. We analysed a comprehensive ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Marine cloud brightening through sea spray injection has been proposed as a climate engineering method for avoiding the most severe consequences of global warming. A limitation of most of the previous modelling studies on ...
-
(Master thesis / Masteroppgave, 2020)The early Holocene marine faunas of the Oslo area were studied in classical works by Brøgger (1901) and others, but there has been relatively little research in recent decades. Classical fossil localities near the marine ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Marine transform faults and associated fracture zones (MTFFZs) cover vast stretches of the ocean floor, where they play a key role in plate tectonics, accommodating the lateral movement of tectonic plates and allowing ...
-
(Chapter / Bokkapittel / AcceptedVersion; Peer reviewed, 2019)Traditional marine seismic sources are facing increasingly strict regulation due to their non-negligible environmental foot print. However, marine vibrators are easy to control, are more efficient and have lower environmental ...
-
(Master thesis / Masteroppgave, 2019)The traditional airgun source has for a long time been the preferred type of source in marine seismic data acquisition due to its high impulsive pressure output. However, this impulsive energy has recently been of concern ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)A detailed, physically based, one dimensional column snowpack model (Crocus) has been incorporated into the hydrological model, Weather Research and Forecasting (WRF)-Hydro, to allow for direct surface mass balance simulation ...
-
(Master thesis / Masteroppgave, 2008)Abstract A two-layer system with a deep lower layer in a semi-infinite ocean is investigated theoretically. Tidal forcing is applied, and expressions for an internal Kelvin wave are derived. Terms of second order in wave ...
-
Mass wasting records the first stages of the Messinian Salinity Crisis in the eastern Mediterranean (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract The geological processes that occurred during the deposition of the Mediterranean salt giant are poorly constrained, limiting our understanding of the earliest phase of the Messinian Salinity Crisis ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)This study evaluates sensitivities of glacier mass balance and runoff to both annual and monthly perturbations in air temperature and precipitation at four highly glacierized catchments: Engabreen in northern Norway and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)This study presents a reconstruction of the seasonal mass balance of Glacier No. 354, located in the Akshiirak range, Kyrgyzstan, from 2003 to 2014. We use a distributed accumulation and temperature-index melt model driven ...
