  • The dynamics of unsteady strait and sill flow 

    Pratt, Lawrence J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1982-04)
    The dynamics of steady and unsteady channel flow over large obstacles is studied analytically and numerically in an attempt to determine the applicability of classical hydraulic concepts to such flows. The study is motivated ...
  • Eddy generation at a convex corner by a coastal current in a rotating system 

    Klinger, Barry A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1992-03)
    Rotating baroclinic and barotropic boundary currents flowing around a corner in the laboratory were studied in order to discover the circumstances under which eddies were produced at the corner. Such flows are reminiscent ...
  • Estimating open-ocean boundary conditions : sensitivity studies 

    Gunson, James R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1995-08)
    The problem of estimating boundary and initial conditions for a regional open-ocean model is addressed here. With the objective of mimicking the SYNOP experiment in the Gulf Stream system, a meandering jet is modeled by ...
  • An experimental study on mixing induced by gravity currents on a sloping bottom in a rotating fluid 

    Ohiwa, Mitchihiro (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2002-09)
    Mixing induced by gravity currents on a sloping bottom was studied through laboratory experiments in a rotating fluid. The dense fluid on the sloping bottom formed a gravity current that could be in regimes where the ...
  • Geochemical and fluid dynamic investigations into the nature of chemical heterogeneity in the Earth's mantle 

    Hauri, Erik H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1992-09)
    Variations in the abundances of elements and radiogenic isotopes in mantle derived peridotites and volcanic rocks are chemical integrals over time, space, and process, which ultimately contain information about the role ...
  • Hydraulics and instabilities of quasi-geostrophic zonal flows 

    Ralph, Elise A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1994-09)
    The thesis addresses the applicability of traditional hydraulic theory to an unstable, mid-latitude jet where the only wave present is the Rossby wave modified by shear. While others (Armi 1989, Pratt 1989, Haynes et ...
  • Interaction of an eddy with a continental slope 

    Wang, Xiaoming (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1992-09)
    This study concerns the barotropic interactions between a mesoscale eddy and a straight monotonic bottom topography. Through simple to relatively complicated modeling effort, some of the fundamental properties of the ...
  • A laboratory study of localized boundary mixing in a rotating stratified fluid 

    Wells, Judith R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2003-02)
    Oceanic observations indicate that abyssal mixing is localized in regions of rough topography. How locally mixed fluid interacts with the ambient fluid is an open question. Laboratory experiments explore the interaction ...
  • A model of a Mediterranean salt lens in external shear 

    Walsh, David (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1992-04)
    A pair of simple models representing the interaction of a continuously stratified f-plane quasigeostrophic lens with a uniform external shear flow is examined. The study is motivated by the desire to understand the ...
  • Predicting eddy detachment from thin jets 

    Ralph, Elise A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1991-08)
    Using a semi-geostrophic, reduced gravity thin jet model, we analytically study the evolution of initial meanders into pinched-off rings. The model used is similar to the path equation developed by Flierl and Robinson ...
  • Response of a pendulum spar to 2-dimensional random waves and a uniform current 

    Rodenbusch, George (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1978-08)
    A linearized theory for the response of a circular pendulum spar in 2-dimensional waves and a uniform current is developed. The linear forces on the cylinder are predicted using an approximate potential flow theory for ...
