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
(Master thesis, 2000) -
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 ... -
En Paleo-Middelhavs stredavsetning: Kalkarenitter tilhørende Azagadorleddet (miocen), Turreområdet, Almeria, SØ Spania
(Master thesis, 2002)The Vera basin is one of several small, intramontane Neogene basins which developed within the Alpine nappes of the Betic Cordillera of southeastern Spain. This system of interconnected basins acted as a marine strait ... -
En rekonstruksjon av variasjoner i breutbredelse gjennom holosen på Svartfjelljøkelen, Bergsfjordhalvøya. En studie basert på proglasiale innsjøsedimenter og kvartærgeologisk kartlegging
(Master thesis, 2012-06-01)Svartfjelljøkelen is a small (5 km2), maritime ice cap situated on a mountain plateau on the Bergsfjord peninsula in Finnmark, Northern Norway, with an average equilibrium line altitude (ELA) close to 870 m altitude. Several ... -
Environmental changes off North Iceland during the deglaciation and the Holocene: foraminifera, diatoms and stable isotopes
(Peer reviewed; Journal article, 2004-02)A combined study of foraminifera, diatoms and stable isotopes in marine sediments off North Iceland records major changes in sea surface conditions since about 15800 cal years (yr) BP. Results are presented from two gravity ... -
The EPOS Research Infrastructure: a federated approach to integrate solid Earth science data and services
(Journal article; Peer reviewed, 2022)The European Plate Observing System (EPOS) is a Research Infrastructure (RI) committed to enabling excellent science through the integration, accessibility, use and re-use of solid Earth science data, research products and ... -
Equilibrium simulations of Marine Isotope Stage 3 climate
(Peer reviewed; Journal article, 2019-06-26)An equilibrium simulation of Marine Isotope Stage 3 (MIS3) climate with boundary conditions characteristic of Greenland Interstadial 8 (GI-8; 38 kyr BP) is carried out with the Norwegian Earth System Model (NorESM). A ... -
Erosjon, avsetninger og mekanismer i forbindelse med dannelsen av Hellmogjelet, Tysfjord, Nord-Norge
(Master thesis, 2013-06-03)Det finnes store krefter i strømmende vann. Kreftene kommer godt til syne når vassdrag flommer over av smeltevann om våren eller etter perioder med mye regn. Hva ville skjedd dersom en vannmengde tilsvarende 2/3 av Amazonas ... -
Erosjonsrater og landskapsutvikling på Andøya, Vesterålen
(Master thesis, 2020-11-03)Andøya antas å ha vært dekket av is flere ganger gjennom kvartærtiden. Området består av både storskala landformer, som strandflaten og platåområder, og mindre landformer som for eksempel morenerygger og smeltevannsgjel. ... -
