    • 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 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 ...

    • 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 ...

    • Topographically Controlled Flow in the Isfjorden Trough and the West Spitsbergen Shelf 

      Vaardal-Lunde, Juni (The University of Bergen, 2011-11-20)
      A one layer numerical model demonstrates how the Atlantic Water (AW) from the West Spitsbergen Current (WSC) is topographically steered onto the West Spitsbergen Shelf (WSS) with a special emphasise on the Isfjorden Trough. ...

    • Tracking Summer Extra-Tropical Storms: A Climatological Overview and Variability in the Northern Hemisphere 

      Mesquita, Michel dos Santos (The University of Bergen, 2006-05-04)

    • Transport of inorganic carbon through, within, and below the ocean surface 

      Lauvset, Siv Kari (The University of Bergen, 2011-03-11)
      Human emissions of CO2 through the burning of fossil fuel, cement production, and land use change have increased the atmospheric CO2 concentration by 39 % since 1750. Without the large uptake of anthropogenic CO2 by the ...

    • Transport Upscaling in Porous Media 

      Nedreli, Anette Cathrine (The University of Bergen, 2014-06-02)
      Numerical models are important for modeling what happens in porous media. In this thesis we will simulate the heat transport in geothermal reservoirs. Because these reservoirs are usually quite large, we will make a model ...

    • Trends in extreme precipitation and the influence by meteorological parameters following the RCP8.5 scenario over 2 catchments in India 

      Soldal, Ingri Halland (The University of Bergen, 2015-06-02)
      The Historical1 simulation (1960-2000) and the RCP8.5 scenario (2060-2100) from the NorESM are used to investigate trends in extreme precipitation, as well as the impact from vertical velocity, specific humidity, divergence ...

    • Turbulent diffusion and transport from a CO2 lake in the deep ocean 

      Haugan, Peter Mosby; Alendal, Guttorm (American Geophysical Union, 2005-09-21)
      If liquid CO2 is stored as a dense ‘‘lake’’ on the deep ocean floor, it is expected to dissolve in seawater. Ocean currents and turbulence can increase the net rate of CO2 release by several orders of magnitude compared ...
