    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 ...
  • Myhre, Gunnar; Stordal, Frode; Johnsrud, M; Kaufman, YJ; Rosenfeld, D; Storelvmo, Trude; Kristjansson, Jon Egill; Berntsen, Terje Koren; Myhre, A; Isaksen, Ivar S A (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2007)
    We have used the MODIS satellite data and two global aerosol models to investigate the relationships between aerosol optical depth (AOD) and cloud parameters that may be affected by the aerosol concentration. The relationships ...

    Atmospheric aerosols from anthropogenic and natural sources reach the polar regions through long-range transport and affect the local radiation balance. Such transport is, however, poorly constrained in present-day global ...
  • Pozer, Bue Edina (Master thesis / Masteroppgave, 2008)
    Abstract The Nesodden study area is part of the complex Southwest Scandinavian Domain in the Baltic Shield. To investigate its magmatic/metamorphic evolution, and to constrain magma sources, 482 in situ LA-MC-ICPMS U-Pb ...
