Earthquake triggered submarine slides in Norway
(Master thesis, 2017-12-16)Towards the end of the last glacial period, several episodes of submarine mass failures has taken place both in Norwegian fjords and on the continental shelf. Submarine mass failures have the potential of generating tsunamis ... -
Earthquake-induced landslides in Norway
(Journal article; Peer reviewed, 2023)Norway is located in an intraplate setting with low-to-moderate seismicity. The mountainous landscape leads to a high level of landside activity throughout the country. Earthquake-induced landslides (EQILs) are common in ... -
Earthquakes track subduction fluids from slab source to mantle wedge sink
(Peer reviewed; Journal article, 2019)Subducting plates release fluids as they plunge into Earth’s mantle and occasionally rupture to produce intraslab earthquakes. It is debated whether fluids and earthquakes are directly related. By combining seismic ... -
Ecology and genomic diversity of iron-oxidizing bacteria at Arctic deep-sea hydrothermal vents: Lessons from genome-resolved metagenomics and microscopy
(Doctoral thesis, 2024-05-08)Jernoksiderende bakterier er globalt utbredt og har betydelig innvirkning på syklusen av jern i miljøet. Imidlertid har få slike bakterier blitt dyrket i laboratoriet og det finnes lite kunnskap om hvordan ulike miljøforhold ... -

Eemian Greenland ice sheet simulated with a higher-order model shows strong sensitivity to surface mass balance forcing
(Peer reviewed; Journal article, 2019-08-15)The Greenland ice sheet contributes increasingly to global sea level rise. Its history during past warm intervals is a valuable reference for future sea level projections. We present ice sheet simulations for the Eemian ... -
Eemian Greenland SMB strongly sensitive to model choice
(Peer reviewed; Journal article, 2018-10-19)Understanding the behavior of the Greenland ice sheet in a warmer climate, and particularly its surface mass balance (SMB), is important for assessing Greenland’s potential contribution to future sea level rise. The Eemian ... -
The effect of radiation screens on Nordic time series of mean temperature
(Peer reviewed; Journal article, 1997-12)A short survey of the historical development of temperature radiation screens is given based upon research in the archives of the Nordic meteorological institutes. In the middle of the nineteenth century most thermometer ... -
Effects of geophysical parameters on the seismic expression of the Maghlaq Fault, Malta: insights from outcrop-based 2D seismic modeling
(Master thesis, 2020-06-25)Faults are heterogenous zones comprising highly complex geometries, which can be studied in detail from field outcrops. The internal complexity of a fault zone is however difficult to interpret from seismic images, due to ... -
Effects of magmatic intrusions on temperature history and diagenesis in sedimentary basins – and the impact on petroleum systems
(Doctoral thesis, 2020-04-23)For many volcanic basins, the thermal effect of igneous intrusions is decisive for their petroleum potential because such thermal impact may lead to maturation of organic material in areas that otherwise would remain ... -
Effects of near-surface thawing on elastic properties and signatures of seismic surface waves
(Master thesis, 2023-09-04)The ongoing temperature rise in the Arctic may have severe effects on large areas of today’s permanently frozen ground. Therefore, it is important to establish robust systems that can monitor permafrost changes with time. ... -
Effects of upscaling and interpolation on log data

Eight-hundred-year temperature variability from the Norwegian continental margin and the North Atlantic thermohaline circulation
(Journal article, 2004-04-17)Four cores raised from the eastern Norwegian Sea and adjacent Norwegian fjords at sites influenced by Atlantic water have been investigated. Oxygen isotope analyses in benthic and planktonic foraminifera are used as a proxy ... -
Ekspulsjon og gassgenerering ved kunstig modning av intakte kildebergartsprøver
(Master thesis, 2016-06-08)Det er utført fem kunstige modningseksperiment på en skiferbergart for å studere effekten av vann og temperaturgradient på generasjon og utdriving av hydrokarboner fra en intakt bergart. Sammensetningen av generert olje ... -
Elastic Full-Waveform Inversion in the Presence of Fracture-Induced Anisotropy
(Master thesis, 2020-06-24)Seismic imaging of the subsurface is essential in both the exploration and production of hydrocarbon reservoirs. Seismic full-waveform modelling and inversion methods can be used to obtain high-resolution images of the ... -
Elastic Imaging and Full Waveform Inversion for Carbon Sequestration
(Master thesis, 2022-06-01)Geological sequestration of carbon dioxide (CO2) is essential to reduce the effects of global warming. However, this requires careful monitoring. Reflection seismics collects data from a large area and is therefore the ... -
Elastic Seismic Imaging and Probabilistic AVO Inversion: Application to CO2 Storage at Sleipner
(Master thesis, 2023-06-01)In order to reduce the effect of global warming, carbon capture and storage (CCS) is considered to be important as it reduces the amount of CO2 in the atmosphere. Geophysical monitoring is essential for safe storage of ... -
Elevars koplingar under feltarbeid i geofag: Ei undersøking av korleis elevar koplar mellom ulike kunnskapar under feltarbeid i geofag
(Master thesis, 2017-08-16)Pedagogiske koplingar og koplingar mellom ulike kunnskapar er ikkje ukjende områder innan geodidaktikk, men områda er lite utforska. Denne studia går meir i djupna på kva typar koplingar som skjer under feltarbeid i geofag. ... -
En kontinuerlig, høyoppløselig rekonstruksjon av brefluktuasjoner på Hambergbreen, Syd Georgia, de siste 1500 år
(Master thesis, 2012-06-01)A sediment record from a distal-glacial fed lake has the potential to contain continuous, high-resolution record of glacial fluctuations backwards in time. In this thesis multiple sediment cores from Middle Hamberg Lake, ... -
En kvalitativ studie av flomsignal i Opo-vassdraget, Vestland fylke
(Master thesis, 2021-08-16)En viktig kilde til informasjon om flomhendelser utover de historiske nedskrivingene er innsjøsedimenter, som fungerer som et arkiv over flommer i nedbørsfeltet. I Opo-vassdraget drenerer mesteparten av vannet til ...
