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 multi-disciplinary Data Portal for integrated access to solid Earth science datasets
(Journal article; Peer reviewed, 2023)The European Plate Observing System (EPOS) is a long-term initiative aimed at integrating research infrastructures for solid Earth science in Europe. EPOS provides a sustainable, multidisciplinary user-oriented platform - ... -
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. ... -
Estimating the volume of the 1978 Rissa quick clay landslide in Central Norway using historical aerial imagery
(Journal article; Peer reviewed, 2022)Quick clay is found across Scandinavia and is especially prominent in south-eastern and central Norway. Quick clay is prone to failure and can cause landslides with high velocities and large run-outs. The 1978 Rissa landslide ... -
Estimation of elastic moduli of mixed porous clay composites
(Peer reviewed; Journal article, 2011-01-13)We have developed a procedure for estimating the effective elastic properties of various mixtures of smectite and kaolinite over a range of confining pressures, based on the individual effective elastic properties of pure ... -

Etablering av holocen askestratigrafi i innsjøarkiver for Vest-Norge
(Master thesis, 2020-07-04)Askestratigrafi er et mye brukt verktøy til kronostratigrafisk korrelering og datering. For vest-norske innsjøer er det tefrakronologiske rammeverket svært begrenset, og en etablering av en askestratigrafi derfra kan gi ... -
