  • Dynamics of the equatorial undercurrent and its termination 

    Wacongne, Sophie H. C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1988-01)
    This study focuses on the zonal weakening, eastern termination and seasonal variations of the Atlantic equatorial undercurrent (EUC). The main and most original contribution of the dissertation is a detailed analysis ...
  • The evolution of upper ocean thermal structure at 10°N, 125°W during 1997-1998 

    Farrar, J. Thomas (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2003-09)
    In this thesis I have endeavored to determine the factors and physical processes that controlled SST and thermocline depth at 10°N, 125°W during the Pan American Climate Study (PACS) field program. Analysis based on the ...
  • Impacts of double-diffusive processes on the thermohaline circulation 

    Zhang, Jubao (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1998-08)
    Double-diffusive processes are studied and parameterized, and their impacts on the oceanic thermohaline circulation are investigated by single-hemisphere numerical models and scaling analysis. Scaling analysis on the ...
  • The modern and glacial thermoclines along the Bahama Banks 

    Slowey, Niall C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1990-09)
    As a primary feature of ocean circulation and a key component of the global carbon cycle, changes in the thermocline must be accounted for if we are to understand the processes involved in Quaternary climatic fluctuation. ...
  • Rotating convection driven by differential bottom heating and its application 

    Park, Young-Gyu (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1996-09)
    A convection experiment was done with a rotating rectangular tank as a model of oceanic meridional overturning circulation. Heat flux was fixed at one bottom end of the tank using an electrical heater. Temperature was ...
  • Shear of small vertical scale observed in the permanent oceanic thermocline 

    Van Leer, John Cloud (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1971-01)
    Two shear experiments performed in the permanent thermocline are described and analyzed in this thesis. The first employed dye streak techniques to gain fractional meter vertical resolution. Shears with small vertical ...
  • Temporal evolution of tritium-³He age in the North Atlantic : implications for thermocline ventilation 

    Robbins, Paul E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1997-09)
    This thesis is a study of the physical mechanisms that ventilate the subtropical thermocline of the eastern North Atlantic. The starting point is an analysis of the existent historical database of natural and anthropogenic ...
  • The thermocline and current structure in subtropical/subpolar basins 

    Huang, Rui Xin (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1984-05)
    Part one of this thesis discusses the structure of the thermocline and the current pattern within a two-layer model. The corresponding flow field is explored as the amount of water in the upper layer is gradually reduced ...
  • Time-dependent ventilated thermocline 

    Liu, Zhengyu (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1991-09)
    In this thesis, I study the time-varying behavior of a ventila ted thermocline with basin scales at annual and decadal time scales. The variability is forced by three external forcings: the wind stress (chapter 3), the ...
