      In the Arctic Ocean, limited measurements indicate that the strongest mixing below the atmospherically forced surface mixed layer occurs where tidal currents are strong. However, mechanisms of energy conversion from tides ...
    • Tidally induced internal motion in an Arctic fjord 

      Støylen, Eivind; Fer, Ilker (Peer reviewed; Journal article, 2014-01-10)
      The internal response in a stratified, partially enclosed basin subject to semi-diurnal tidal forcing through a narrow entrance is investigated. The site is located above the critical latitude where linear internal waves ...
    • Tides and shallow water dynamics near Tromsø 

      Espenes, Håvard (Master thesis, 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 (Master thesis, 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 Coast ...
    • Tilpasning av elektronisk innsprøytningssystem, type Common Rail, for en én-sylindret dieseldrevet laboratoriemotor 

      Tingstad, Jarle (Master thesis, 2017-06-23)

    • Time Scales and Sources of European Temperature Variability 

      Årthun, Marius; Kolstad, Erik Wilhelm; Eldevik, Tor; Keenlyside, Noel (Peer reviewed; Journal article, 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 (Peer reviewed; Journal article, 2015-11)

    • 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 ...
