    We present a unique time series of continuous glacier frontal ablation rates with weekly resolution over 15 years estimated from seismic calving observations at Kronebreen, Svalbard. Using linear statistical models, we ...
  • Paul, Frank; Strozzi, Tazio; Schellenberger, Thomas; Kääb, Andreas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The Karakoram mountain range is well known for its numerous surge-type glaciers of which several have recently surged or are still doing so. Analysis of multi-temporal satellite images and digital elevation models have ...
  • Wrona, Thilo; Magee, Craig; Fossen, Haakon; Gawthorpe, Rob; Bell, Rebecca E.; Jackson, Christopher Aiden Lee; Faleide, Jan Inge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    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 ...
  • Asgedom, Endrias Getachew (Master thesis / Masteroppgave, 2009)
    In this thesis we present a three-dimensional (3-D) seismic SV-wave speed model for the upper mantle beneath Northern Europe derived from the analysis of fundamental mode Rayleigh waveforms. Selecting recordings with ...
  • Kjoberg, Sigurd; Schmiedel, Tobias; Planke, Sverre; Svensen, Henrik; Millett, John; Jerram, Dougal Alexander; Galland, Olivier; Lecomte, Isabelle; Schofield, Nick; Haug, Øystein Thorden; Helsem, Andreas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    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 ...
  • Kjoberg, Sigurd (Master thesis / Masteroppgave, 2016)
    This thesis presents a 3D seismic analysis of fluid and gas induced hydrothermal vent complexes in a 310 km2 area at the Møre Basin, offshore Norway. The mid-Norwegian Møre Margin is regarded as a type example of a volcanic ...
  • 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, ...
  • Ma, Qiumei; Xiong, Lihua; Xia, Jun; Xiong, Bin; Yang, Han; Xu, Chong-Yu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Satellite precipitation estimates (SPE) provide useful input for hydrological modeling. However, hydrological modeling is frequently hindered by large bias and errors in SPE, inducing the necessity for bias corrections. ...
  • 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, ...
  • Schobben, Martin; Gravendyck, Julia; Mangels, Franziska; Struck, Ulrich; Bussert, Robert; Kürschner, Wolfram Michael; Korn, Dieter; Sander, P Martin; Aberhan, Martin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Stratigraphic studies are an integral component in understanding the chronology of events that led to the end-Triassic mass extinction, by resolving causal relationships between environmental upheavals and biotic response. ...
  • 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 ...
  • Sun, Jing; Slang, Sigmund; Elboth, Thomas; Greiner, Thomas Larsen; McDonald, Steven; Gelius, Leiv-J. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)
    For economic and efficiency reasons, blended acquisition of seismic data is becoming increasingly commonplace. Seismic deblending methods are computationally demanding and normally consist of multiple processing steps. ...
  • Jiang, Shanhu; Wang, Menghao; Ren, Liliang; Xu, Chong-Yu; Yuan, Fei; Liu, Yi; Lu, Yujie; Shen, Hongren (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Climate change and human activities are two major driving forces affecting the hydrologic cycle, which further influence the stationarity of the hydrologic regime. Hydrological drought is a substantial negative deviation ...
  • 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 ...

    Abstract. The climate in Svalbard is undergoing amplified change compared to the global mean. This has major implications for runoff from glaciers and seasonal snow on land. We use a coupled energy balance–subsurface model, ...
