    • Topographic effects on CO2, diffusion and dissolution from the seafloor 

      Rygg, Kristin; Enstad, Lars Inge; Alendal, Guttorm; Haugan, Peter Mosby (Peer reviewed; Journal article, 2009-02)
      At 3000 meters depth liquid CO2 is denser than seawater and hence will be stored as a “lake” on the deep ocean floor, which is expected to gradually be dissolved in seawater. Ocean currents and turbulence will influence ...
    • Topographic Effects on Strong Winds in Southern Norway; A Case Study of the Storm Dagmar 

      Solbrekke, Ida Marie (Master thesis, 2014-06-02)
      During the 25th of December 2011 a strong low pressure system struck Soutwestern Norway. This rapidly evolving system got the name "Dagmar". The aim of this thesis was to find out how the complex topography in Southern ...
