A first continuous three-year temperature record from the dimictic arctic–alpine Lake Tarfala, northern Sweden
(Journal article; Peer reviewed, 2021)Arctic lakes are exposed to warming during increasingly longer ice-free periods and, if located in glaciated areas, to increased inflow of meltwater and sediments. However, direct monitoring of how such lakes respond to ... -
Flaumar i Vossavassdraget, kan dei påvisast i innsjøsediment
(Master thesis, 2003) -
Fluid evolution from extension to compression in the Pyrenean Fold Belt and Basque-Cantabrian Basin: A review
(Journal article; Peer reviewed, 2023)We propose a review to discuss the large number of studies dealing with the fluid history in extensional and compressional sedimentary basins that evolved along the Iberian-Eurasian plate boundary during the full ... -
Fluid flow properties of the Wilhelmøya Subgroup,a potential unconventional CO2 storage unit in central Spitsbergen
(Peer reviewed; Journal article, 2019)The Upper Triassic to Middle Jurassic Wilhelmøya Subgroup forms one of the more suitable reservoir units on the Norwegian Arctic archipelago of Svalbard. The target siliciclastic storage unit, which is encountered at approx. ... -
Fluid migration pathways to seafloor seepage in inner Isfjorden and Adventfjorden, Svalbard
(Peer reviewed; Journal article, 2014)This study represents a marine baseline study for the Longyearbyen CO2 Lab, in which CO2 may be injected in the Upper Triassic–Middle Jurassic Kapp Toscana Group, which comprises several permeable beds. The target ... -
Forced regression in rift shoulder derived deltas
(Master thesis, 2018-06-30)Footwall uplift and migration of fault activity have led to the preservation of spectacular down-stepping Gilbert-type deltas at the southern margin of the Corinth Rift. It is the purpose of this thesis to present the ... -
Forovermodellering og inversjon av 3D og 4D CSEM-data basert på integralligningsmetoder
(Master thesis, 2010-06-01)Elektromagnetiske undersøkelser blir benyttet i letesammenheng for å skille mellom vann- og hydrokarbonfylte prospekt, og dermed øke sannsynligheten for å finne hydrokarboner. I forovermodellering, benyttes ulike ... -
Four billion years of ophiolites reveal secular trends in oceanic crust formation
(Peer reviewed; Journal article, 2014-07)We combine a geological, geochemical and tectonic dataset from 118 ophiolite complexes of the major global Phanerozoic orogenic belts with similar datasets of ophiolites from 111 Precambrian greenstone belts to construct ... -
Fracture formation due to differential compaction under glacial load: a poro-elastoplastic simulation of the Hugin Fracture
(Journal article; Peer reviewed, 2021)The Hugin Fracture, discovered in 2011, is an approximately 3.5 km long seafloor fracture in the North Sea. This fracture was unexpected and, due to the geology in the North Sea no obvious explanation could be found. In ... -
Fracture-generated permeability and groundwater yield in Norway
(Peer reviewed; Journal article, 2002)The transport of groundwater in bedrock is largely determined by interconnected fractures and their apertures. The conditions by which fractures become interconnected are thus of primary importance in understanding ... -
Frictional properties and microstructural evolution of dry and wet calcite-dolomite gouges
(Journal article; Peer reviewed, 2021)Calcite and dolomite are the two most common minerals in carbonate-bearing faults and shear zones. Motivated by observations of exhumed seismogenic faults in the Italian Central Apennines, we used a rotary-shear apparatus ... -
From Caledonian collapse to North Sea Rift: The extended history of a metamorphic core complex
(Journal article; Peer reviewed, 2020)Extensional systems evolve through different stages due to changes in the rheological state of the lithosphere. It is crucial to distinguish ductile structures formed before and during rifting, as both cases have important ... -
From field analogues to realistic seismic modelling: a case study of an oil-producing andesitic sill complex in the Neuquén Basin, Argentina
(Peer reviewed; Journal article, 2018)Interpretation of seismic data has played a major role in recent advances in the studies of igneous sill complexes. Seismic modelling studies based on field analogues represent a promising tool to close the scale gap between ... -
From mountains to basins: geochronological case studies from southwestern Norway, Western Australia and East Antarctica
(Doctoral thesis, 2012-03-02) -
From outcrop to Ground Penetrating Radar images with Point-Spread Function based convolution modelling
(Master thesis, 2021-01-15) -
From slab rollback to orogenic plateau formation: a numerical modelling study of ocean-continent subduction systems
(Master thesis, 2016-05-30)The crustal structures of overriding plates in subduction settings around the world can vary between a large variety of deformation styles, ranging from extensional structures and back arc opening induced by slab roll back, ... -
Full Waveform Inversion and Multi-Diagonal Inversion for Monitoring of CO2 Storage at Sleipner
(Master thesis, 2023-06-01)Carbon capture and storage (CCS) can become necessary for mitigating climate change. However, storing CO2 in subsurface reservoirs requires thorough monitoring. The most accurate and widespread type of monitoring is seismic ... -
Future state of Norwegian glaciers: Estimating glacier mass balance and equilibrium line responses to projected 21st century climate change
(Journal article; Peer reviewed, 2023)Glaciers and ice caps in Norway are presently undergoing mass loss, areal reduction, and frontal retreat, mainly a result of increased summer ablation due to rising summer temperatures over Scandinavia, especially after ... -
Generation of intermediate-depth earthquakes and the fate of subduction fluids : Insights from mantle wedge seismicity and case studies in the Western Hellenic subduction zone
(Doctoral thesis, 2019-06-07)The occurrence of intermediate depth earthquakes at 50-300 km depth in subduction zones is puzzling, because high temperatures and pressures at these depths do not allow standard brittle failure. Instead, two main candidate ... -
Genomes of Thaumarchaeota from deep sea sediments reveal specific adaptations of three independently evolved lineages
(Journal article; Peer reviewed, 2021)Marine sediments represent a vast habitat for complex microbiomes. Among these, ammonia oxidizing archaea (AOA) of the phylum Thaumarchaeota are one of the most common, yet little explored, inhabitants, which seem ...
