The Svelvik ridge was approved by local authorities as a CO2 field lab in 2008 and the appraisal phase for this project was completed in the summer of 2010. This operation gave a valuable insight of the subsurface and ...
Travel time approximations, including higher-order terms, to extend the applicability of Kirchhoff time migration. 
Kulathilagan, Piratheeben (Master thesis / Masteroppgave, 2011)
Abstract Seismic time migration is a cost and time effective process for imaging of the subsurface. However, the approach is traditionally limited to velocity models with mildly varying lateral variations. The objective ...
De-noising Seismic Data by Empirical Mode Decomposition 
Saeed, Baseem Saeed (Master thesis / Masteroppgave, 2011)
This thesis investigates the application of the Empirical Mode Decomposition (EMD) and Ensemble Empirical Mode Decomposition (EEMD) techniques in de-noising of marine seismic data. EMD decomposes the seismic dataset into ...
Fault architecture of reactivated faults in Carboniferous sediments, Northumberland, Great Britain 
Kjemperud, Magnus Vestheim (Master thesis / Masteroppgave, 2011)
The relationship between extreme weather events and slide events in Norway 
Krzystyniak, Magdalena Natalia (Master thesis / Masteroppgave, 2011)
Norway is a country that is frequently exposed to extreme weather events (EWEs).Norway experienced EWEs every year. The characteristic of extreme weather events is that they occur infrequently and normally result in ...
The Ritland impact structure: : Characteristics and distribution of the ejecta layer and associated Lower Paleozoic sedimentary succession 
Setså, Ronny (Master thesis / Masteroppgave, 2011)
The newly discovered Ritland impact structure is located in Hjelmeland Municipality in Rogaland County, Western Norway. The structure is 2,7 km in diameter, about 350 meters deep and probably of Early/Middle Cambrian age. ...
Provenance of the Asker Group, Oslo Rift : A detrital zircon U-Pb and Lu-Hf study 
Kristoffersen, Magnus (Master thesis / Masteroppgave, 2011)
To identify possible protosources for the Asker Group 573 in situ LA-MC-ICPMS uranium-lead and 509 lutetium-hafnium analyses were performed on detrital zircon grains from seven samples. The samples from the Kolsås and ...
Fault architecture in extensional faults affecting sandstone, Northumberland, Great Britain 
Valdresbråten, Marie Lovise Rostad (Master thesis / Masteroppgave, 2011)
Determinig the kinetic energy spectrum in the upper ocean 
Løvdahl, Rafael E (Master thesis / Masteroppgave, 2011)
Changes in the Upper Arctic Ocean Hydrography from Observational Data Restricted Access
Fossli, Ida (Master thesis / Masteroppgave, 2011)
The Arctic Ocean is supplied with water from the Atlantic and Pacific through the Nordic Seas and the Bering Strait. Changes in temperature, salinity and density are seen in the Amundsen, Makarov and Beaufort Basins. The ...
Kvantifisering av effekten for reflektert sol- og himmellys på målinger av oppoverspredt lys fra havet foretatt fra passasjerskip, sammenlignet med satellittestimater av oppoverspredt lys. 
Kleiv, Øyvind (Master thesis / Masteroppgave, 2011)
Observed impact of aerosols on Arctic cloud emissivity 
Grythe, Henrik (Master thesis / Masteroppgave, 2011)
IPCC results indicate that the main bulk of uncertainties on global warming is within aerosol-cloud interactions. Based on observations this thesis aims to measure how anthropogenic aerosol from mid-latitudes increase ...
The Polar Low in the Norwegian Sea March 16-17 2008 
Engdahl, Bjørg Jenny Kokkvoll (Master thesis / Masteroppgave, 2011)
The polar low in the Norwegian Sea on March 16-17 2008 has been studied using both weather analysis and the numerical weather prediction (NWP) model weather research and forecasting (WRF). This particular polar low was ...
Det polare lavtrykket nord for Svalbard, 8. januar 2010. : Modellstudie av drivmekanismene bak det polare lavtrykket 
Martinsen, Nina (Master thesis / Masteroppgave, 2011)
Extreme mesoscale weather in the Arctic region often forms in the vicinity of the ice edge. A polar low was observed in the region between Svalbard and the ice cap, 8. january 2010. This was the first polar low to have ...
Lavfrekvent variabilitet i havet, i observasjoner og modeller 
Skattør, Hanne (Master thesis / Masteroppgave, 2011)
I denne oppgaven har vi studert lavfrekvent variabiliteten i havet gjennom det 20-århundret. I tillegg til observasjoner har vi brukt data fra fire klimamodeller; CCSM3, Gfdl-CM2.0, BCM2.0 og HadCM3, som er kjørt med ...
