Sen-holocene maringeologiske avsetningsprosesser i Førdefjorden
(Master thesis, 2022-06-01)Fjordlandskapet langs den vestnorske kysten er viktige maringeologiske arkiv grunnet deres semi-isolerte morfologi. Fjordbassengenes sedimentære avsetninger består hovedsakelig av sediment knyttet til proksimale- og distale ... -
Sen-weichsel og tidlig holosen strandforskyvning i Os-området, Hordaland
(Master thesis, 2000)Late Weichselian and Early Holocene relative sea-level changes in four isolation basins in the Os area, Hordaland (Western Norway) were studied using both bio- and lithostratigraphical methods. Isolation and ingression ... -
Senglasiale vulkanske askelag i innsjøsedimenter på Vestlandet
(Master thesis, 2006-03-15)A sediment core from a peat bog on Dimnøy at Sunnmøre, western Norway has been investigated in order to search for volcanic ash horizons. A new volcanic ash with a geochemistry more or less identical to the rhyolitic ... -
Sensitivity of clumped isotope temperatures in fossil benthic and planktic foraminifera to diagenetic alteration
(Peer reviewed; Journal article, 2019)Applying the clumped isotope (Δ47) thermometer to foraminifer microfossils offers the potential to significantly improve paleoclimate reconstructions, owing to its insensitivity to the isotopic composition of seawater ... -
Sensitivity of the Greenland surface mass and energy balance to uncertainties in key model parameters
(Journal article; Peer reviewed, 2021)We investigate the sensitivity of a distributed glacier surface mass and energy balance model using a variance-based analysis, for two distinct periods of the last glacial cycle: the present day (PD) and the Last Glacial ... -
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 ... -
Shallow-water hydrothermal venting linked to the Palaeocene–Eocene Thermal Maximum
(Journal article; Peer reviewed, 2023)The Palaeocene–Eocene Thermal Maximum (PETM) was a global warming event of 5–6 °C around 56 million years ago caused by input of carbon into the ocean and atmosphere. Hydrothermal venting of greenhouse gases produced in ... -
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 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. ... -
Simultaneous tracking of multiple whales using two fiber-optic cables in the Arctic
(Journal article; Peer reviewed, 2023-04-28)Climate change is impacting the Arctic faster than anywhere else in the world. As a response, ecosystems are rapidly changing. As a result, we can expect rapid shifts in whale migration and habitat use concurrent with ... -
