  • Opstad, Haakon Olai (Master thesis / Masteroppgave, 2005)
    Hammerfestbassenget ligger i bassengprovinsen sør i det vestlige Barentshavet og er et sammensatt sedimentærbasseng, 70 km bredt og 150 km langt, som utviklet seg fra sen jura til tidlig kritt. Prøvesettet i denne ...
  • Doubrovine, Pavel; Steinberger, Bernhard; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Absolute reconstructions of large igneous provinces (LIPs) for the past 300 Ma reveal a remarkable spatial pattern suggesting that almost all LIPs have erupted over the margins of the two large‐scale structures in the ...
  • Waldeland, Anders Ueland; Zhao, Hao; Faccipieri, J. H.; Solberg, Anne H Schistad; Gelius, Leiv-J. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The common-reflection-surface (CRS) method offers a stack with higher signal-to-noise ratio at the cost of a time-consuming semblance search to obtain the stacking parameters. We have developed a fast method for extracting ...
  • Noack, Marcus Michael; Gillberg, Tor (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Eikonal models have been widely used for traveltime computations in the field of seismic imaging, but they are often criticized for having low accuracy and poor resolution of the output image. Including amplitude information ...
  • Endresen, Ola Torstein (Master thesis / Masteroppgave, 2017)
    Fastmerker etableres for å oppnå et stabilt punkt med så lav punktdeformasjon som mulig. Så langt det er mulig velges også områder med faste, stabile masser for plassering av fastmerker. Av flere årsaker kan det likevel ...
  • Mulrooney, Mark Joseph (Doctoral thesis / Doktoravhandling, 2018)
    The PhD thesis is a collection of four articles that investigate the controls of syn- and post-kinematic faulting on reservoirs. Case studies from the Barents Shelf are presented (Svalbard and the Hammerfest Basin). Offshore ...
  • Sørvik, Gard Ove (Master thesis / Masteroppgave, 2008)
    Feltarbeid regnes som en essensiell del av geografiutdanningen. Feltarbeid, førstehåndserfaringer tilegnet i et feltområde, blir beskrevet og diskutert for å gi et innblikk i en av geografiundervisningens viktigste metoder. ...
  • Dillen, Menno; Lindeberg, Erik Gøsta Brun; Aagaard, Per; Aker, Eyvind; Sæther, Ola Magne; Johansen, Harald; Lien, Martha; Hatzignatiou, Dimitrios Georgios; Golmen, Lars Gunder; Hellevang, Jon Oddvar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2009)
    The long-term safety of future CO2 storage projects in aquifers will not only rely on a comprehensive geological characterisation of the formation and capillary seal, but also on the ability to effectively monitor the ...
  • Foss, Mariann Kløverød (Master thesis / Masteroppgave, 2008)
    Hygroskopiske aerosolpartikler sveller i fuktige omgivelser. Ammoniumsulfat er et eksempel på en hygroskopisk aerosolpartikkel, og den sveller ikke-lineært ved relativ fuktighet over 81%. Svelling øker den optiske tykkelsen ...
  • Bakkehøi, Helge (Master thesis / Hovedoppgave, 2003)
    Abstract This work focuses on the two towns most exposed for flooding in Norway: Lillestrøm which lies alongside Lake Øyeren, and Hamar which is situated near Norway’s largest lake, Mjøsa. The main objective of this work ...
  • Jacobsen, Marianne (Master thesis / Hovedoppgave, 2003)
    To learn more about the fluids that were present in the Canary Islands oceanic crust during the magmatism, fluid inclusions in gabbroic xenoliths from Lanzarote and La Palma have been studied. The fluids were originally ...
  • Plümper, Oliver; Botan, Alexandru; Los, Catharina; Liu, Yang; Malthe-Sørenssen, Anders; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    The transport of fluids through the Earth’s crust controls the redistribution of elements to form mineral and hydrocarbon deposits, the release and sequestration of greenhouse gases, and facilitates metamorphic reactions ...
  • Berge, Sigrid Hägg (Master thesis / Hovedoppgave, 2004)
    Store deler av Svalbard var i tidsrommet sen trias mellom jura en grunn shelf med kondensert sedimentasjon. Knorringfjellformasjonen representerer avsetningene fra denne perioden i sentrale deler av Spitsbergen. Vekslende ...
  • Guilmette, Carl; Smit, Matthijs A.; van Hinsbergen, Douwe J J; Gurer, Derya; Corfu, Fernando; Charette, Benoit; Maffione, Marco; Rabeau, Olivier; Savard, Dany (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Subduction zones are unique to Earth and fundamental in its evolution, yet we still know little about the causes and mechanisms of their initiation. Numerical models show that far-field forcing may cause subduction initiation ...
  • Huneeus, Nicolas; Boucher, Olivier; Alterskjær, Kari; Cole, Jason N.S.; Curry, Charles L.; Ji, Duoying; Jones, Andy; Kravitz, Ben; Kristjansson, Jon Egill; Moore, John C.; Muri, Helene; Niemeier, Ulrike; Rasch, Philip J.; Robock, Alan; Singh, Baldwinder; Schmidt, Hauke; Schulz, Michael; Tilmes, Simone; Watanabe, Shingo; Yoon, Yin-ho (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    The effective radiative forcings (including rapid adjustments) and feedbacks associated with an instantaneous quadrupling of the preindustrial CO2 concentration and a counterbalancing reduction of the solar constant are ...
  • Prieur, Nils Charles; Rolf, Tobias; Wünnemann, Kai; Werner, Stephanie C. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Impact crater morphologies vary significantly across the lunar maria. Craters with diameter less than 400 m are closely related to variations in target properties (rock strength, porosity, and layering) as well as the ...
  • Halvorsrud, Finn Roar (Master thesis / Hovedoppgave, 2007)
    Oslomarka er en fellesbetegnelse på området som ligger i fem fylker og 19 kommuner øst, sørøst, vest og nord for Oslo. Totalt dekker Oslomarka et område på 0,4 % av Norges areal, men er et potensielt friluftslivs- og ...
  • Austrheim, Håkon Olaf; Dunkel, Kristina G; Plümper, Oliver; Ildefonse, Benoit; Liu, Yang; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Fractures and faults riddle the Earth’s crust on all scales, and the deformation associated with them is presumed to have had significant effects on its petrological and structural evolution. However, despite the abundance ...
  • Hellmann, Thomas (Master thesis / Hovedoppgave, 2005)
    In this thesis, I present the results of a new approach to pre-stack Kirchoff depth migration using the Kirchoff algorithm and the Fresnel aperture features in order to improve the signal-to-noise ratio of the seismic data ...
