      The mixed layer is an important component of the oceanic circulation system. Recent progress in energetics of the oceanic circulation suggests that the amount of external mechanical energy available for mixing is directly ...
    • 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 ...
    • Dynamics in the deep Canada Basin, Arctic Ocean, inferred by thermistor chain time series 

      Timmermans, Mary-Louise; Melling, Humfrey; Rainville, Luc (American Meteorological Society, 2007-04)
      A 50-day time series of high-resolution temperature in the deepest layers of the Canada Basin in the Arctic Ocean indicates that the deep Canada Basin is a dynamically active environment, not the quiet, stable basin often ...
    • Dynamics of an idealized Beaufort Gyre : 1. The effect of a small beta and lack of western boundaries 

      Yang, Jiayan; Proshutinsky, Andrey; Lin, Xiaopei (John Wiley & Sons, 2016-02-12)
      The Beaufort Gyre in the Arctic Ocean differs from a typical moderate-latitude gyre in some major aspects of its dynamics. First, it is located in a basin without a western boundary, which is essential for closing midlatitude ...
    • 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 ...
    • Dynamics of circular arrangements of vorticity in two dimensions 

      Vilasur Swaminathan, Rohith; Ravichandran, S.; Perlekar, Prasad; Govindarajan, Rama (2016-06)
      The merger of two like-signed vortices is a well-studied problem, but in a turbulent ow, we may often have more than two like-signed vortices interacting. We study the merger of three or more identical co-rotating ...
    • Dynamics of downwelling in an eddy-resolving convective basin 

      Spall, Michael A. (American Meteorological Society, 2010-10)
      The mean downwelling in an eddy-resolving model of a convective basin is concentrated near the boundary where eddies are shed from the cyclonic boundary current into the interior. It is suggested that the buoyancy-forced ...
    • Dynamics of freshwater plumes : observations and numerical modeling of the wind-forced response and alongshore freshwater transport 

      Fong, Derek A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1998-06)
      A freshwater plume often forms when a river or an estuary discharges water onto the continental shelf. Freshwater plumes are ubiquitous features of the coastal ocean and usually leave a striking signature in the coastal ...
    • Dynamics of global ocean heat transport variability 

      Jayne, Steven R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1999-02)
      A state-of-the-art, high-resolution ocean general circulation model is used to estimate the time-dependent global ocean heat transport and investigate its dynamics. The north-south heat transport is the prime manifestation ...
    • Dynamics of Greenland’s glacial fjords 

      Jackson, Rebecca H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-06)
      Glacial fjords form conduits between glaciers of the Greenland Ice Sheet and the North Atlantic. They are the gateways for importing oceanic heat to melt ice and for exporting meltwater into the ocean. Submarine melting ...
    • Dynamics of Langmuir circulation in oceanic surface layers 

      Gnanadesikan, Anand (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1994-09)
      This work investigates whether large-scale coherent vortex structures driven by wave-current interaction (Langmuir circulation) are responsible for maintaining the oceanic mixed layer. Langmuir circulations dominate the ...
    • Dynamics of marine zooplankton : social behavior ecological interactions, and physically-induced variability 

      Verdy, Ariane (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2008-02)
      Marine ecosystems reflect the physical structure of their environment and the biological processes they carry out. This leads to spatial heterogeneity and temporal variability, some of which is imposed externally and ...
    • 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 ...
