  • Indrevær, Kjetil; Gabrielsen, Roy Helge; Faleide, Jan Inge (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Tectonic inversion of rift basins is most commonly reported in the literature to occur after rifting has ceased. In contrast, we present evidence for synrift, localized tectonic inversion from the Loppa High area, southwestern ...
  • Torsvik, Trond Helge; Steinberger, Bernhard; Ashwal, Lewis D.; Doubrovine, Pavel; Trønnes, Reidar G (Journal article / Tidsskriftartikkel / SubmittedVersion, 2016)
    Kevin Burke’s original and thought-provoking contributions have been published steadily for the past 60 years, and more than a decade ago he set out to resolve how plate tectonics and mantle plumes interact by proposing a ...
  • Jamtveit, Bjørn; Ben-Zion, Yehuda; Renard, Francois; Austrheim, Håkon Olaf (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    The structural and metamorphic evolution of the lower crust has direct effects on the lithospheric response to plate tectonic processes involved in orogeny, including subsidence of sedimentary basins, stability of deep ...
  • Ferre, Eric C.; Meado, Andrea L; Geissman, John W; Di Toro, Giulio; Spagnuolo, Elena; Ueda, Tadamasa; Ashwal, Lewis D.; Deseta, Natalie; Andersen, Torgeir Bjørge; Filiberto, Justin; Conder, James A (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Ultramafic pseudotachylytes have been regarded as earthquake fossils formed at mantle depths (i.e., >30 km). Here we show that pseudotachylytes hosted by ultramafic rocks from three localities have distinct magnetic ...
  • Nasipuri, Pritam; Corfu, Fernando; Bhattacharya, A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    There is consensus that, at 1.0–0.9 Ga, the granulites in the Eastern Ghats Province (EGP), Eastern India, and the Rayner Complex, Antarctica, were parts of a coherently evolved crustal block. Paleogeographic reconstructions ...
  • Sperrevik, Ann Kristin (Master thesis / Masteroppgave, 2008)
    As global warming causes both glaciers and sea ice to decay, increased freshwater flux into the North Atlantic is expected. In addition precipitation at high latitudes is predicted to increase under global warming as well, ...
  • Nooraiepour, Mohammad; Bohloli, Bahman; Park, Joonsang; Sauvin, Guillaume; Skurtveit, Elin; Mondol, Nazmul Haque (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Fracture networks inside geological CO2 storage reservoirs can serve as primary fluid flow conduit, particularly in low-permeability formations. While some experiments focused on the geophysical properties of brine- and ...
  • Kalani, Mohsen; Zadeh, Mohammad Koochak; Jahren, Jens; Mondol, Nazmul Haque; Faleide, Jan Inge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Pore pressure in fine-grained rocks is important with respect to drilling problems such as kicks, blowouts, borehole instability, stuck pipe and lost circulation. In this study, a succession of overpressured, fine-grained, ...
  • Prieur, Nils Charles; Rolf, Tobias; Luther, Robert; Wunnemann, Kai; Xiao, Zhiyong; Werner, Stephanie C. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The effects of the coefficient of friction and porosity on impact cratering are not sufficiently considered in scaling laws that predict the crater size from a known impactor size, velocity, and mass. We carried out a ...
  • Michalsen, Martin Aleksander (Master thesis / Masteroppgave, 2018)
    Dynamical runout models are essential tools in landslide hazard and risk assessment, because they allow us to simulate the motion of past landslides and to predict the motion of future landslides. Runout distances obtained ...
  • Miri, Rohaldin (Doctoral thesis / Doktoravhandling, 2015)
    Carbon capture and storage (CCS) in geological reservoirs – especially saline aquifers – is a key midterm solution to mitigate climate changes caused by increasing anthropogenic CO2. In order to ensure that a CCS project ...
  • Zheng, Xiaojiao; Cordonnier, Benoit; Zhu, Wenlu; Renard, Francois; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Hydration of a nominally dry rock can cause expansion of the solid volume, resulting in reaction‐induced fracturing and an associated increase in the porosity and permeability of the rock. We study the effect of confinement ...
  • Sundal, Anja; Nystuen, Johan Petter; Dypvik, Henning; Miri, Rohaldin; Aagaard, Per (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    In characterizing subsurface reservoirs for CO2 storage, the geological heterogeneity distribution is of importance with respect to the injectivity and migration paths. The object of this study is a saline aquifer of ...
  • Rydsaa, Johanne Hope; Stordal, Frode; Bryn, Anders; Tallaksen, Lena M. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Shrub expansion in high latitudes is a widely observed response to climate change. Extensive evidence has shown that shrub expansion can lead to positive feedbacks to the regional climate. In this study we evaluate the ...
  • Haugsmark, Liv Katerine (Master thesis / Hovedoppgave, 2004)
    Abstract This thesis is written as a part of the Cand. Scient. degree at the Institute for Geosciences at the University of Oslo. Traditionally, age determinations of late Cretaceous chalks in the Central Graben in the ...
  • Forsström, S.; Isaksson, Elisabeth; Skeie, Ragnhild Bieltvedt; Ström, Johan; Pedersen, CA; Hudson, S.R.; Berntsen, Terje Koren; Lihavainen, H.; Godtliebsen, Fred; Gerland, Sebastian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    [1] Black carbon (BC) and other light-absorbing particles deposited on snow and ice are known to perturb the surface radiative balance. There are few published observations of the concentration of these particles in the ...
  • Altena, Bas; Kääb, Andreas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Optical satellite products are available at different processing levels. Of these products, terrain corrected (i.e., orthorectified) products are the ones mostly used for glacier displacement estimation. For terrain ...
  • Moholdt, Geir (Doctoral thesis / Doktoravhandling, 2010)
    This thesis uses ground-based, airborne and spaceborne elevation measurements to estimate elevation change and mass balance of glaciers and ice caps on the Svalbard archipelago in the Norwegian Arctic. Remote sensing data ...
  • Myhre, Marianne (Master thesis / Masteroppgave, 2005)
    Oppgaven presenterer et klassifiseringssystem for inndeling av elvelandskapstyper langs vassdrag, og er utviklet for at det skal kunne brukes på ulike typer vassdrag. Antall elvelandskapstyper kan variere etter representativitet ...
  • Kleivane, Ingeborg (Master thesis / Masteroppgave, 2005)
    Hovudmålet med oppgåva har vore å lage ein metode for å klassifisere elvelandskap. Elvelandskap er definert som planmønster saman med naturtypen på elvebreidda. Hovudverktøyet skal vere M711-kartserien, og støtteverktøy ...
