    When continents rift, magmatism can produce large volumes of melt that migrate upwards from deep below the Earth’s surface. To understand how magmatism impacts rifting, it is critical to understand how much melt is generated ...
  • 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 ...

    The mid-Norwegian margin is regarded as an example of a volcanic-rifted margin, formed prior to and during, Paleogene breakup of the northeast Atlantic. The area is characterized by the presence of voluminous basaltic ...
  • Boike, Julia; Juszak, Inge; Lange, Stephan; Chadburn, Sarah; Burke, Eleanor; Paul Overduin, Pier; Roth, Kurt; Ippisch, Olaf; Bornemann, Niko; Stern, Lielle; Gouttevin, Isabelle; Hauber, Ernst; Westermann, Sebastian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Most permafrost is located in the Arctic, where frozen organic carbon makes it an important component of the global climate system. Despite the fact that the Arctic climate changes more rapidly than the rest of the globe, ...
  • Pall, Pardeep; Tallaksen, Lena M.; Stordal, Frode (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Rain-on-snow (ROS) events are multivariate hydrometeorological phenomena that require a combination of rain and snowpack, with complex processes occurring on and within the snowpack. Impacts include floods and landslides, ...
  • Steinberger, Bernhard; Becker, Thorsten W. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    The outermost layer of the solid Earth consists of relatively rigid plates whose horizontal motions are well described by the rules of plate tectonics. Yet, the thickness of these plates is poorly constrained, with different ...
  • Helle, Tonje Eide; Aagaard, Per; Nordal, Steinar; Long, Michael; Bazin, Sara (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    The sediments at the NTNU research site Dragvoll, Trondheim, Norway accumulated in seawater close to the glacier front during the Pleistocene-Holocene transition. A comprehensive site investigation and laboratory test ...
  • Weber, Jan Erik H. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    By using a direct Lagrangian formulation, two different solutions for the nonlinear motion in inviscid internal gravity waves between horizontal planes in a non-rotating fluid are discussed. The first solution assumes a ...
  • Tegner, Christian; Andersen, Torgeir Bjørge; Kjøll, Hans Jørgen; Brown, Eric L.; Hagen-Peter, Graham; Corfu, Fernando; Planke, Sverre; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Abstract The origin of Large Igneous Provinces (LIPs) associated with continental breakup and the reconstruction of continents older than c. 320 million years (pre-Pangea) are contentious research problems. Here we study ...
  • Zhuan, Meijia; Chen, Jie; Xu, Chong-Yu; Zhao, Cha; Xiong, Lihua; Liu, Pan (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Climate model response (M) and greenhouse gas emissions (S) uncertainties are consistently estimated as spreads of multi‐model and multi‐scenario climate change projections. There has been less agreement in estimating ...
  • Curry, Charles L.; Sillmann, Jana; Bronaugh, David; Alterskjær, Kari; Cole, Jason N.S.; Ji, Duoying; Kravitz, Ben; Kristjansson, Jon Egill; Moore, John C.; Muri, Helene Østlie; Niemeier, Ulrike; Robock, Alan; Tilmes, Simone; Yang, Shuting (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    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 ...
