  • 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 ...
  • On the flow induced in a thermally stratified fluid by a source of heat 

    Knox, Robert A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1971-06)
    The flow produced by an infinitely long horizontal heated strip in a thermally stratified fluid is examined theoretically. For strong stratification a long flat convection cell or tongue results. Profiles of velocity and ...
  • Experiments in a rotating source-sink annulus 

    Ingram, Richard Grant (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1971-08)
    An experimental investigation of the different flow regimes in a rotating source-sink annulus is described. Both the steady and transient velocities are measured over a large range of Ekman Reynolds number and Rossby number. ...
  • Drag coefficients of vibrating synthetic rope 

    Charnews, Daniel Paul (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1971-09)
    The drag, amplitude, frequency tension, diameter and length of synthetic ropes vibrating because of vortex-induced forces, and net vibrating at different tensions were measured. Photographs were taken of the vortices. Drag ...
  • The relationship between microscales and wind-wave spectral development 

    Dorman, Craig E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1971-10)
    The objective of this study was to describe the mechanics of wind wave generation and spectral development. Intermittency, high frequency microstructure in wind and wave fields, and strong nonlinear coupling involving a ...
  • The gravity field and plate boundaries in Venezuela 

    Folinsbee, Robert Allin (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1972-01)
    Free-air and simple Bouguer anomaly maps of the Venezuelan continental margin (from 60°W to 72°W and from 7°N to 13°N) are presented. The major features of the free-air map are: the large lows associated with the deep ...
  • On the calculation of wind stress curl over open ocean areas from synoptic meteorological data with application to time dependent ocean circulation 

    Welch, Christopher Slocombe (Woods Hole Oceanographic Institution, 1972-02)
    The method used by N. P. Fofonoff for estimating wind stress curl from surface atmospheric pressure maps is developed for use with the National Meterological Center analysis grid. A formula is developed relating the wind ...
  • Motion sensitivity of flame ionization detectors 

    Gularte, Ronald Carl (Woods Hole Oceanographic Institution, 1972-05)
    A portable gas chromatograph, using a single flame ionization detector, was constructed. The unit was tested for response to surge, sway and heave accelerations up to 0.3g. Also the detector's response was studied for ...
  • Nonlinear interactions among standing surface and internal gravity waves 

    Joyce, Terrence M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1972-06)
