Sensitivity of the Northeast Greenland Ice Stream to Geothermal Heat
(Peer reviewed; Journal article, 2019-12-20)Recent observations of ice flow surface velocities have helped improve our understanding of basal processes on Greenland and Antarctica, though these processes still constitute some of the largest uncertainties driving ice ... -
The sequence stratigraphic development of the Late Permian Kapp Starostin Formation, central Spitsbergen
(Master thesis, 2016-06-01)This study investigated the sedimentology and the sequence stratigraphy of the Late Permian Kapp Starostin Formation in the southwestern part of Dickson Land, central Spitsbergen. The underlying Gipshuken Formation and the ... -
Sequential growth of deformation bands in carbonate grainstones in the hangingwall of an active growth fault: Implications for deformation mechanisms in different tectonic regimes
(Peer reviewed; Journal article, 2016-09)Deformation bands in porous sandstones have been extensively studied for four decades, whereas comparatively less is known about deformation bands in porous carbonate rocks, particularly in extensional settings. Here, we ... -
Shear zone evolution during core complex exhumation – Implications for continental detachments
(Journal article; Peer reviewed, 2020)The formation of low-angle detachments involves exhumation of previously ductile material and fault zone weakening. To better understand this relationship, we studied a deeply eroded metamorphic core complex, which formed ... -
SHMIP The subglacial hydrology model intercomparison Project
(Peer reviewed; Journal article, 2018-10-24)Subglacial hydrology plays a key role in many glaciological processes, including ice dynamics via the modulation of basal sliding. Owing to the lack of an overarching theory, however, a variety of model approximations exist ... -
Silicate weathering in soils: A solution for soil pH management?
(Master thesis, 2015-09-30)N2O released form agricultural soils is mainly a product of denitrification; a key microbial process in the N cycle. The relative rate of N2O released from this process depends of the soil pH, where the relative amount of ... -
Simulated retreat of Jakobshavn Isbræ since the Little Ice Age controlled by geometry
(Peer reviewed; Journal article, 2018-07-12)Rapid retreat of Greenland's marine-terminating glaciers coincides with regional warming trends, which have broadly been used to explain these rapid changes. However, outlet glaciers within similar climate regimes ... -

(Peer reviewed; Journal article, 2018-07-12)Rapid retreat of Greenland's marine-terminating glaciers coincides with regional warming trends, which have broadly been used to explain these rapid changes. However, outlet glaciers within similar climate regimes experience ... -
Simulating last interglacial climate with NorESM: role of insolation and greenhouse gases in the timing of peak warmth
(Peer reviewed; Journal article, 2014-07-10)The last interglacial (LIG, ~130–116 ka, ka = 1000 yr ago) is characterized by high-latitude warming and is therefore often considered as a possible analogue for future warming. However, in contrast to predicted ... -
Simulating the climatic response of Hardangerjøkulen in southern Norway since the Little Ice Age
(Master thesis, 2014-05-24)Glacier and ice cap volume changes currently amount to half of the total contribution from the cryosphere to sea-level rise. Ice caps and their outlet glaciers are dynamically different from the Greenland and Antarctic ice ... -
Simulating the evolution of Hardangerjøkulen ice cap in southern Norway since the mid-Holocene and its sensitivity to climate change
(Peer reviewed; Journal article, 2017-01-27)Understanding of long-term dynamics of glaciers and ice caps is vital to assess their recent and future changes, yet few long-term reconstructions using ice flow models exist. Here we present simulations of the maritime ... -
Simulation of seismic attributes for earth models with different continuity properties
(Master thesis, 2019-11-21)The combination of kinematic and dynamic ray tracing has been used since the 1970s for simulation (modelling) of seismic energy in the subsurface. Kinematic/dynamic ray tracing is used to simulate the travel time, amplitude ... -
Simulation of the Eemian Greenland ice sheet
(Doctoral thesis, 2019-03-05)This thesis focuses on the simulation of the Greenland ice sheet (GrIS) during the Eemian interglacial period (~125,000 years ago). The warm Eemian summers on Greenland are used as a past analogue for future warmer conditions. ... -
Siste istids maksimum og deglasiasjon av nordøstlige deler av Nordsjøen; glasiale prosesser og landskapsformer
(Master thesis, 2012-11-20)Hovedformålet med denne oppgaven har vært å kartlegge glasiale erosjons- og avsetningsformer i nordlige deler av Norskerenna, for å fremskaffe et mer detaljert bilde av Norskerennaisstrømmens tilbaketrekningsmønster, ... -
Skreddersying og optimalisering av separasjonsprosedyrer for isolasjon av kvarts fra bergarter basert på bergartsdannelse og mineralinnhold
(Master thesis, 2017-06-29)Preparering for eksponeringsdatering er en prosess som er både tidkrevende og dyr, hvor bergartsprøvene må gjennom mange delprosedyrer før det aktuelle mineralet er isolert for datering. På Kosmolab benyttes en felles ... -
Skredfarekartlegging i Uskedalen, Kvinnherad kommune - basert på feltobservasjoner, schmidthammermålinger og empiriske modeller
(Master thesis, 2018-06-30)This master thesis is exploring the avalanche hazards in Uskedalen, Norway. Avalanche hazard mapping is an important mitigation measure for hazardous areas. Information about avalanche deposits and terrain gained through ... -
Skredfarekartlegging i Votedalen. Basert på feltobservasjoner, klimastudier, empiriske modeller og dateringsmetoder
(Master thesis, 2016-06-01)Avalanche hazard mapping is an important mitigation measure for hazardous areas. It helps to better understand what areas that need to be secured and what safety measures that should be considered. The combination of such ... -
