      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 ...

      Six cruises were made from May, 1978 to May, 1979 to measure the regional distributions of chlorophyll, silicate, nitrate and nitrite, phosphate, temperature, and salinity in the vacinity of Nantucket Shoals on the New ...
    • 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 ...
    • 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 ...
    • 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 ...
