    There have been many opinions on the definition of solifluction since the expression was first used by J. G. Andersson in 1906. The original definition was “slow flowing from higher to lower ground of masses of waste ...
  • Stagge, James Howard; Kingston, Daniel G.; Tallaksen, Lena M.; Hannah, David M. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Recent severe European droughts raise the vital question: are we already experiencing measurable changes in drought likelihood that agree with climate change projections? The plethora of drought definitions compounds this ...
  • Altena, Bas (Doctoral thesis / Doktoravhandling, 2018)
    In the last couple of years many Earth observation satellites with optical instruments have been set in space. These satellites generate an enormous amount of data and give us a image of different landforms on Earth. The ...
  • Tegtmeier, S.; Ziska, Franziska; Pisso, Ignacio; Quack, B; Velders, G. J. M.; Yang, X.; Krüger, Kirstin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    At present, anthropogenic halogens and oceanic emissions of very short-lived substances (VSLSs) both contribute to the observed stratospheric ozone depletion. Emissions of the long-lived anthropogenic halogens have been ...
  • Justino, Flavio; Lindemann, Douglas; Kucharski, Fred; Wilson, Aaron; Bromwich, David; Stordal, Frode (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Marine Isotope Stage 31 (MIS31, between 1085 and 1055 ka) was characterized by higher extratropical air temperatures and a substantial recession of polar glaciers compared to today. Paleoreconstructions and model simulations ...
  • Kolstrup, Marianne Lanzky (Doctoral dissertation / Doktoravhandling, 2015)
    This dissertation investigates the physical structure of the crust and upper mantle in southwestern Scandinavia using different seismological and non-seismologic geophysical methods: 1. The S-wave velocity structure of ...
  • Rydsaa, Johanne H. (Doctoral thesis / Doktoravhandling, 2016)
  • Aas, Eyvind (Research report / Forskningsrapport, 1969)
  • Shephard, Grace Elizabeth; Matthews, Kara J.; Hosseini, Kasra; Domeier, Mathew (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The geoscience community is increasingly utilizing seismic tomography to interpret mantle heterogeneity and its links to past tectonic and geodynamic processes. To assess the robustness and distribution of positive seismic ...
  • Breien, Hedda (Master thesis / Masteroppgave, 2005)
    Abstract Debris flows represent a major threat to human life and property. Due to their ability of entraining material and reaching long run-outs, they have a potential of causing massive damage. There are many studies ...
  • Köhler, Andreas; Weidle, Christian; Maupin, Valerie (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2012)
    Due to the increasing popularity of analyzing empirical Green’s functions obtained from ambient seismic noise, more and more regional tomographical studies based on short-period surface waves are published. Results could ...
  • Van Pham, Thi H; Aagaard, Per; Hellevang, Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    Continental flood basalts (CFB) are considered as potential CO2 storage sites because of their high reactivity and abundant divalent metal ions that can potentially trap carbon for geological timescales. Moreover, laterally ...
  • Faccenna, Claudio; Becker, Thorsten W.; Lallemand, Serge; Steinberger, Bernard (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    We analyze the role of slab pull acting on the Pacific plate during its early Tertiary change in motion. Slab pull forces are estimated by integrating the negative buoyancy of a 700 km long slab along a revised subduction ...
  • Aas, Eyvind; Højerslev, Niels Kristian; Høkedal, Jo; Sørensen, Kai (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    A new map of Jerlov’s optical water types in the Nordic Seas and adjacent waters at 139 locations, as well as a table with statistical and geographical properties of the vertical attenuation coefficient of downward irradiance ...
  • Morstad, Bjørn Petter (Master thesis / Masteroppgave, 2008)
    SAMMENDRAG Oppgavens hydrologiske problemstilling er knyttet til Maridalsvassdragets nedbørfelt i Oslo. Det 255 km² store feltet har 26 regulerbare magasiner og er et typisk Østlandsvassdrag med snøsmelteflommer og ...
