Exploring seismic detection and resolution thresholds of fault zones and gas seeps in the shallow subsurface using seismic modelling
(Journal article; Peer reviewed, 2022)Seismic resolution and illumination issues are sources of challenges in the detailed imaging and detection of subsurface fault architecture and fluid migration. Improved constraints on resolution can provide input into ... -
Exploring the Microseismicity of the Gakkel Ridge from Arctic Sea Ice
(Master thesis, 2013-06-03)Monitoring of microseismicity is an important tool to understand the magmatism, tectonics and hydrothermal circulation of a mid-oceanic ridge. In the presence of sea ice, use of ocean bottom seismometers is not practical, ... -
Extending local magnitude ML to short distances
(Peer reviewed; Journal article, 2019)Local magnitudes calculated at stations less than 10 km from earthquakes in the British Isles are up to one unit of magnitude higher than local magnitudes calculated at more distant stations. This causes a considerable ... -
Extensional inheritance and surface processes as controlling factors of mountain belt structure
(Peer reviewed; Journal article, 2014-12)Surface processes and inherited structures are widely regarded as factors that strongly influence the evolution of mountain belts. The first-order effects of these parameters have been studied extensively throughout the ... -
Extent and Volume of Lava Flows Erupted at 9°50′N, East Pacific Rise in 2005–2006 From Autonomous Underwater Vehicle Surveys
(Journal article; Peer reviewed, 2022)Seafloor volcanic eruptions are difficult to directly observe due to lengthy eruption cycles and the remote location of mid-ocean ridges. Volcanic eruptions in 2005–2006 at 9°50′N on the East Pacific Rise have been well ... -
Facies Analysis and Sandbody Geometry of the Paleogene Battfjellet Formation, Central Western Nordenskiöld Land, Spitsbergen
(Master thesis, 2010)New sedimentological data from the central part of Nordenskiöld Land, Spitsbergen, contributes to the understanding of the depositional processes and sandbody geometry of the Battfjellet Formation (Eocene). A detailed ... -
Facies Architecture and Paleogeography of the Battfjellet Formation, Rypefjellet, Spitsbergen
(Master thesis, 2010-06-01)The shallow marine sandstones of the Battfjellet Fm are part of a regressive mega-sequence that represent the last stages of infilling of the Paleogene Central Basin in Spitsbergen. The Battfjellet Fm is believed to be of ... -
Facies composition and scaling of extensional faults in sedimentary rocks and its applications to modelling of fault zones
(Doctoral thesis, 2010-01-08) -
Facies model for a coarse-grained, tide-influenced delta: Gule Horn Formation (Early Jurassic), Jameson Land, Greenland
(Peer reviewed; Journal article, 2016-05-25)Tide-dominated deltas have an inherently complex distribution of heterogeneities on several different scales, and are less well-understood than their wave- and river-dominated counterparts. Depositional models of these ... -
Facies, palynostratigraphy and sequence stratigraphy of the Wilhelmøya Subgroup (Upper Triassic–Middle Jurassic) in western central Spitsbergen, Svalbard
(Peer reviewed; Journal article, 2019)The Wilhelmøya Subgroup (Norian–Bathonian) is considered as the prime storage unit for locally produced CO2 in Longyearbyen on the Arctic archipelago of Svalbard. We here present new drillcore and outcrop data and refined ... -

Fault core and its geostatistical analysis: Insight into the fault core thickness and fault displacement
(Master thesis, 2017-06-23)Fault core is a high-strain zone of a fault, which accommodate intense deformation. Due to high strain, complex structures and intensely deformed fault rocks form in the fault core, which again affects the geometry and ... -
Fault core thickness: Insights from siliciclastic and carbonate rocks
(Peer reviewed; Journal article, 2019-06-02)Fault core accommodates intense deformation in the form of slip surfaces and fault rocks such as fault gouge, cataclasite, breccia, lenses, shale smear, and diagenetic features. The complexity and variation in fault core ... -
Fault Facies Modelling: 3D representation of faults in petroleum reservoirs
(Master thesis, 2008-06-30)The purpose of a reservoir model is to act as a tool for optimizing development and production strategies for subsurface hydrocarbon reservoirs. Such a model is intended to be predictive, and to act as a map for the ones ... -
Fault sealing and fluid contact control in Gullfaks Sør
(Master thesis, 2023-11-06)In subsurface reservoirs, understanding the fault sealing capacity is important to predict the amount of hydrocarbons present in the reservoirs. Some earlier literature has emphasized using shale gouge ratio (SGR) to predict ... -
Fault Zone Characterization and Monitoring of CO2 Storage using Full Waveform Inversion
(Master thesis, 2023-06-01)CO2 storage in geological formations is essential to limit global warming and reduce the effects of climate change. In order to store CO2 safely and prevent leakage, proper sealing mechanisms are required. Faults are complex ... -
Fault-controlled fluid circulation and diagenesis along basin-bounding fault systems in rifts - Insights from the East Greenland rift system
(Journal article; Peer reviewed, 2020-11-05)In marine rift basins, deep-water clastics (>200 m) in the hanging wall of rift- or basin-bounding fault systems are commonly juxtaposed against crystalline “basement” rocks in the footwall. A distinct feature of such fault ... -
Faults architecture and their scaling relationships: Insights into fault core thickness and fault displacement
(Master thesis, 2012-10-01)The purpose of this study is to investigate the statistical characteristics of fault core thickness and fault displacement, and to state the relationship between these two fault attributes. Field work was carried out At ... -
A first chronology for the East Greenland Ice-core Project (EGRIP) over the Holocene and last glacial termination
(Journal article; Peer reviewed, 2020)This paper provides the first chronology for the deep ice core from the East Greenland Ice-core Project (EGRIP) over the Holocene and the late last glacial period. We rely mainly on volcanic events and common peak patterns ... -
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 ...
