    • Testing a Flexible Method to Reduce False Monsoon Onsets 

      Reeve, Mathew Alexander; Spengler, Thomas; Chu, Pao-Shin (PLoS, 2014-08-08)
      To generate information about the monsoon onset and withdrawal we have to choose a monsoon definition and apply it to data. One problem that arises is that false monsoon onsets can hamper our analysis, which is often ...

    • Tides and shallow water dynamics near Tromsø 

      Espenes, Håvard (The University of Bergen, 2018-06-20)
      I have investigated the tidal dynamics near Tromsø using data from some observations and from a numerical model. These data show that currents relating to the shallow water tides are very pronounced at the Tromsøysund and ...

    • Tides Structures and Mixing along the Mozambique Coast 

      Nhapulo, Candida Ines Sete (The University of Bergen, 2010-06-01)
      The resolution of environment problems suggests the study of tidal structures and mixing along the Mozambique Coast. Sofala Bank is the area with more available information for this study. Tides along the Mozambique ...

    • Time Scales and Sources of European Temperature Variability 

      Årthun, Marius; Kolstad, Erik Wilhelm; Eldevik, Tor; Keenlyside, Noel (Wiley, 2018-04)
      Skillful predictions of continental climate would be of great practical benefit for society and stakeholders. It nevertheless remains fundamentally unresolved to what extent climate is predictable, for what features, at ...

    • A toolbox for secondary quality control on ocean chemistry and hydrographic data 

      Lauvset, Siv Kari; Tanhua, Toste (Wiley, 2015-11)
      High quality, reference measurements of chemical and physical properties of seawater are of great importance for a wide research community, including the need to validate models and attempts to quantify spatial and temporal ...

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

      Rygg, Kristin; Enstad, Lars Inge; Alendal, Guttorm; Haugan, Peter Mosby (Elsevier, 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 (The University of Bergen, 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 ...
