  • Maupin, Valerie (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The ellipticity of the Rayleigh wave at the surface depends on the seismic structure beneath and in the vicinity of the seismological station where it is measured. We derive here the expression and compute the 3-D kernels ...

    Temperature and precipitation extremes are examined in the Geoengineering Model Intercomparison Project experiment G1, wherein an instantaneous quadrupling of CO2 from its preindustrial control value is offset by a ...
  • Noack, Marcus Michael (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    tWave form modeling is used in a vast number of applications. Therefore, different methods have beendeveloped that exhibit different strengths and weaknesses in accuracy, stability and computational cost.The latter remains ...
  • Køltzow, Morten Andreas Ødegaard (Doctoral thesis / Doktoravhandling, 2012)
  • Crameri, Fabio; Lithgow-Bertelloni, Carolina (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    The sinking remnant of a surface plate crosses and interacts with multiple boundaries in Earth's interior. Here, we specifically investigate the prominent dynamic interaction of the sinking plate portion with the upper-mantle ...
  • Steinberger, Bernard; Torsvik, Trond Helge; Dubrovin, Pavel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    We defined a new global moving hot spot reference frame (GMHRF), using a comprehensive set of radiometric dates from arguably the best‐studied hot spot tracks, refined plate circuit reconstructions, a new plate polygon ...
  • Aas, Eyvind (Research report / Forskningsrapport, 1987)
  • Van Hinsbergen, Douwe; Steinberger, Bernard; Gassmöller, René; Dubrovin, Pavel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)
    A strong 50–35 Ma decrease in India‐Asia convergence is generally ascribed to continent‐continent collision. However, a convergence rate increase of similar magnitude occurred between ∼65–50 Ma. An earlier increase occurred ...
  • Minakov, Alexander; Keers, Henk; Kolyukhin, Dmitriy; Tengesdal, Hans Christian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The seismic oceanography method is based on extracting and stacking the low-frequency acoustic energy scattered by the ocean heterogeneity. However, a good understanding on how this acoustic wavefield is affected by physical ...
  • Piciullo, Luca; Dahl, Mads-Peter; Devoli, Graziella; Colleuille, Hervé; Calvello, Michele (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The Norwegian national landslide early warning system (LEWS), operational since 2013, is managed by the Norwegian Water Resources and Energy Directorate and was designed for monitoring and forecasting the hydrometeorological ...
