  • On the propagation of free topographic Rossby waves near continental margins 

    Ou, Hsien Wang (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1979-04)
    Observational work by Thompson (1977) and others has demonstrated that free topographic Rossby waves propagate northward up the continental rise south of New England. To study the dynamical implications of these waves ...
  • Analysis and interpretation of tidal currents in the coastal boundary layer 

    May, Paul Wesley (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1979-05)
    Concern with the impact of human activities on the coastal region of the world's oceans has elicited interest in the so-called "coastal boundary layer"-that band of water adjacent to the coast where ocean currents ...
  • Observations of long period waves in the tropical oceans and atmosphere 

    Luther, Douglas S. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1980-02)
    The existence of resonant, baroclinic, equatorially-trapped inertia-gravity waves (discovered by Wunsch and Gill (1976)) is confirmed in the mid-Pacific by spectral analysis of long sea level records. The energy of the ...
  • Observations and models of inertial waves in the deep ocean 

    Fu, Lee-Lueng (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1980-02)
    The structure of the inertial peak in deep ocean kinetic energy spectra is studied here. Records were obtained from Polymode arrays deployed in the Western North Atlantic Ocean (40°W to 70°W, 15°N to 42°N). The results ...
  • Wintertime convection and frontal interleaving in the Southern Ocean 

    Toole, John M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1980-03)
    The Southern Ocean as defined here is the body of water between the Antarctic Continent and the Antarctic Polar Front, (APF). This ocean is considered important in the global thermodynamic balance of the ocean-atmosphere ...
  • Seasonal variability in the intermediate water of the eastern North Atlantic 

    Bray, Nancy Amanda (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1980-08)
    Observational evidence of seasonal variability below the main thermocline in the eastern North Atlantic is described, and a theoretical model of oceanic response to seasonally varying windstress forcing is constructed to ...
  • The dynamics and kinematics of the coastal boundary layer off Long Island 

    Pettigrew, Neal R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1980-12)
    Data from the COBOLT experiment, which investigated the first 12 km off Long Island's south shore, are analyzed and discussed. Moored current meter records indicate that the nearshore flow field is strongly polarized ...
  • The influence of the mid-Atlantic ridge upon the circulation and the properties of the Mediterranean water southwest of the Azores 

    Joyce, Terrence M. (Woods Hole Oceanographic Institution, 1981-06)
    The warm, salty water influenced by the Mediterranean outfow can be observed at mid-depth throughout the Central North Atlantic Ocean. Katz (1970) first noted that rather than a gradual salinity decrease away from the ...
  • The vertical structure of the wind-driven circulation 

    Young, William R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1981-08)
    This thesis consists of three loosely related theoretical studies. In chapters 1 - 3 the physical mechanisms which determine the three dimensional structure of the currents in the Sverdrup interior of a wind-driven gyre ...
  • The dynamics of mean circulation on the continental shelf 

    Shaw, Ping-Tung Peter (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1982-02)
    Mean long-isobath drift of the order 5 cm/sec has been observed on several continental shelves, e.g. in the Middle Atlantic Bight and in the Weddell Sea. A theoretical model is developed to explore the driving mechanism ...
  • 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 ...
  • Observed circulation and inferred sediment transport in Hudson Submarine Canyon 

    Hotchkiss, Frances Luellen Stephenson (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1982-05)
    Velocity and temperature time series from Hudson Submarine Canyon and hydrographic surveys of seven canyons of the Middle Atlantic Bight indicate that the effects of storms, tides, and incoming internal waves are intensified ...
  • The development of nonlinear surface and internal wave groups 

    Chereskin, Teresa K. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1982-08)
    The development of nonlinear surface and internal wave groups is investigated. Surface wave evolution was observed in an unusually long wave channel as a function of steepness and group length. Dissipation and frequency ...
  • Atmospheric interactions with Gulf Stream Rings 

    Dewar, William K. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1982-10)
    Four different problems concerning Gulf Stream Rings are considered. The first deals with the particle trajectories of, and advection-diffusion by, a dynamic model of a Ring. It is found that the streaklines computed ...
  • Algorithms for computation of fundamental properties of seawater 

    Fofonoff, Nick P.; Millard, Robert C. (Unesco, 1983)
    Algorithms for computation of fundamental properties of seawater, based on the practical salinity scale (PSS-78) and the international equation of state for seawater (EOS-80), are compiled in the present report for ...
  • The oceanographic and geoidal components of sea surface topography 

    Zlotnicki, Victor (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1983-02)
    Altimetric, gravimetric and oceanographic data over the North Atlantic are combined -using techniques of optimum estimation- to infer the surface expression of the time averaged circulation (ζ) and to estimate the ...
  • Inverse methods and results from the 1981 Ocean Acoustic Tomography Experiment 

    Cornuelle, Bruce D. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1983-04)
