    • 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 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 ...

      Reactive oxygen species (ROS) are key players in the health and biogeochemistry of the ocean and its inhabitants. The vital contribution of microorganisms to marine ROS levels, particularly superoxide, has only recently ...
    • 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 ...
    • The dynamics of geometrically compliant mooring systems 

      Gobat, Jason I. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2000-06)
      Geometrically compliant mooring systems that change their shape to accommodate deformations are common in oceanographic and offshore energy production applications. Because of the inherent geometric nonlinearities, ...
    • 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 ...
    • Dynamics of myosin, microtubules, and Kinesin-6 at the cortex during cytokinesis in Drosophila S2 cells 

      Vale, Ronald D.; Spudich, James A.; Griffis, Eric R. (Rockefeller University Press, 2009-08)
      Signals from the mitotic spindle during anaphase specify the location of the actomyosin contractile ring during cytokinesis, but the detailed mechanism remains unresolved. Here, we have imaged the dynamics of green fluorescent ...
    • Dynamics of N removal over annual time periods in a suburban river network 

      Wollheim, Wilfred M.; Peterson, Bruce J.; Thomas, Suzanne M.; Hopkinson, Charles S.; Vorosmarty, Charles J. (American Geophysical Union, 2008-09-23)
      River systems are dynamic, highly connected water transfer networks that integrate a wide range of physical and biological processes. We used a river network nitrogen (N) removal model with daily temporal resolution to ...
