  • The design of a surface launch and recovery fender for DSRV "Alvin" 

    O'Sullivan, James Francis (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1973-09)
    Surface recovery of small submersibles could be made safer for personnel and hardware with the installation on the submersible of an inflatable, pneumatic bumper which acts also as main surface buoyancy. Tne use of such ...

    Forsyth, Donald W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1973-09)
    The dispersion of Love and Rayleigh waves in the period range 17-167 sec. is used to detect the change in the structure of the upper mantle as the age of the sea-floor increases away from the mid-ocean ridge. Using the ...
  • The dynamics of bottom boundary currents in the ocean 

    Smith, Peter C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1973-09)
    This thesis presents an investigation of the dynamics of bottom boundary currents in the ocean. The major emphasis is to develop simple mathematical models in which various dynamical features of these complex geophysical ...
  • Sedimentary processes on the continental slope off New England 

    MacIlvaine, Joseph Chad (Woods Hole Oceanographic Institution, 1973-09)
    A detailed study of a small (5000 km2) area of the continental slope south of Cape Cod, Massachusetts, was conducted. Bathymetry, 3.5 kHz profiles, seismic profiles, suspended sediment analysis, bottom photographs, television ...
  • Late quaternary sedimentation in the Eastern Angola Basin 

    Bornhold, Brian D. (Woods Hole Oceanographic Institution, 1973-11)
    Recent sedimentation in the eastern Angola Basin includes calcareous oozes in the north and south (Guinea Rise and Walvis Ridge) and hemipelagic lutites and terrigenous turbidites on the Congo Cone and on the Angola rise ...
  • The history of sedimentation and abyssal circulation on the Greater Antilles outer ridge 

    Tucholke, Brian E. (Woods Hole Oceanographic Institution, 1974-01)
    The Greater Antilles Outer Ridge is an 1800 km long, submarine sedimentary ridge which lies below 5000 m in the southwestern North Atlantic Ocean. Seismic reflection profiles and core data indicate that the ridge is ...
  • Heat loss and hydrothermal circulation due to sea-floor spreading 

    Williams, David Lee (Woods Hole Oceanographic Institution, 1974-07)
    Lithospheric cooling along the Galapagos Spreading Center at 86°W longitude, as determined by surface heat-flow measurements, appears dominated by hydrothermal circulation. This same phenomena apparently exists on the ...
  • Analysis of a high resolution deep ocean acoustic navigation system 

    Durham, James Leighton (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1975-01)
    A high resolution acoustic navigation system for ocean use is being developed at the Woods Hole oceanographic Institution. The system can yield navigation fixes with respect to a bottom moored reference net with accuracies ...
  • Structural evaluation of fixed offshore platforms 

    Vandiver, J. Kim (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1975-01)
    In fixed offshore structures, damage incurred below the waterline is often difficult to detect, but significant enough to be the source of a subsequent massive failure. A technique is described that can be used to detect ...
  • Creep buckling of shells of revolution loaded under uniform external pressure 

    Sullivan, Paul Francis (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1975-01)
    A theoretical investigation is undertaken into the creep instability of two common shells of revolution, the infinitely long cylinder and the complete sphere. The linear and non-linear visco-elastic material idealizations ...
  • The generation, energetics and propagation of internal tides in the western North Atlantic Ocean 

    Hendry, Ross MacRae (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1975-04)
    This thesis reports on an investigation into the structure, energetics and propagation of tidal frequency internal waves. Data from Site D, near the New England continental slope, Muir Seamount northeast of Bermuda, and ...
  • The relationship between cupric ion activity and the toxicity of copper to phytoplankton 

    Sunda, William (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1975-04)
    The purpose of this investigation is to quantify the relationship between cupric ion activity and the toxicity of copper to phytoplankton and further to study the effect on copper toxicity of naturally occurring organic ...
  • Transient structure in benthic communities : the effects of oxygen stress, burial and high rates of sedimentation 

    Nichols-Driscoll, Jean (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1975-04)
    The influence of natural short-term fluctuations in environmental parameters on three components of transient benthic invertebrate community structure: abundance of individuals and species, biomass of individuals, ...
  • The vertical propagation of inertial waves in the ocean 

    Leaman, Kevin Douglas (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1975-06)
    A set of vertical profiles of horizontal ocean currents, obtained by electro-magnetic profilers in the Atlantic Ocean southwest of Bermuda in the spring of 1973, has been analyzed in order to study the vertical structure ...
  • Distribution of hydrocarbons in a salt marsh ecosystem after an oil spill and physiological changes in marsh animals from the polluted environment 

    Burns, Kathryn A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1975-06)
