      Wang, Jinbo (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2011-06)

    • Instability and energetics in a baroclinic ocean 

      Kim, Kuh (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1975-08)
      This thesis is made of two separate, but interrelated parts. In Part I the instability of a baroclinic Rossby wave in a two-layer ocean of inviscid fluid without topography, is investigated and its results are applied ...

    • An integrated modal approach to surface and volume scattering in ocean acoustic waveguides 

      Tracey, Brian H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1996-01)
      Acoustic propagation in the ocean can be strongly affected by small random variations in ocean properties, including rough surfaces and volume fluctuations in the ocean or seabed. Such inhomogeneities scatter part of the ...
    • Integrating bioenergetics and foraging behavior : the physiological ecology of larval cod (Gadus morhua) 

      Ruzicka, James J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2004-06)
      How do larval cod, Gadus morhua, balance foraging effort against the high cost of swimming in a viscous hydrodynamic regime? A respirometry system was developed to measure the activity metabolism of individual larvae. ...
    • Inter-annual variability of acoustic ray travel times in the northeast Pacific 

      Furgerson, John A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1990-09)
      An acoustic tomography experiment consisting of a source near Hawaii and seven receivers along the west coast of North America was conducted from November 1987 to May 1988 and from February 1989 to July 1989. In this ...
    • Interacting populations : hosts and pathogens, prey and predators 

      Klepac, Petra (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2007-06)
      The interactions between populations can be positive, neutral or negative. Predation and parasitism are both relationships where one species benefits from the interaction at the expense of the other. Predators kill their ...
    • Interaction of an eddy with a continental slope 

      Wang, Xiaoming (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1992-09)
      This study concerns the barotropic interactions between a mesoscale eddy and a straight monotonic bottom topography. Through simple to relatively complicated modeling effort, some of the fundamental properties of the ...
    • Interaction of high frequency internal waves and the boundary layer on the continental shelf 

      Sanford, Lawrence P. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1984-08)
      Intermittent, shoreward propagating packets of high frequency first mode internal waves are common on the continental shelf when the water column is stratified and may induce large fluctuations in near bottom velocity. ...
    • The interaction of metal ions at the hydrous manganese dioxide-solution interface 

      Murray, James W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1973-06)
      An experimental study of the interaction of metal ions with the surface of hydrous manganese dioxide has been completed. The results of these experiments have greatly improved our qualitative understanding of the adsorption ...
    • Interactions between calanoid copepod hosts and their associated microbiota 

      Almada, Amala A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2015-02)
      Copepods are highly abundant environmental reservoirs of many bacterial pathogens. This thesis investigates whether copepod physiology influences the abundance and community structure of its microbiome. To this end, we ...
    • Interactions between mantle plumes and mid-ocean ridges : constraints from geophysics, geochemistry, and geodynamical modeling 

      Georgen, Jennifer E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2001-09)
      This thesis studies interactions between mid-ocean ridges and mantle plumes using geophysics, geochemistry, and geodynamical modeling. Chapter 1 investigates the effects of the Marion and Bouvet hotspots on the ultra-slow ...
    • Interactions of cadmium, zinc, and phosphorus in marine Synechococcus : field uptake, physiological and proteomic studies 

      Cox, Alysia D. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2011-06)
      A combination of uptake field studies on natural phytoplankton assemblages and laboratory proteomic and physiological experiments on cyanobacterial isolates were conducted investigating the interactions of cadmium (Cd), ...
    • Interannual variability of the Pacific Water boundary current in the Beaufort Sea 

      Brugler, Eric T. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2013-09)
      Between 2002 and 2011 a single mooring was maintained in the core of the Pacific Water boundary current in the Alaskan Beaufort Sea near 152° W. Using velocity and hydrographic data from six year-long deployments during ...
    • Internal hydraulic jumps with upstream shear 

      Ogden, Kelly A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
      Internal hydraulic jumps in flows with upstream shear are investigated numerically and theoretically. The role of upstream shear has not previously been thoroughly investigated, although it is important in many oceanographic ...
    • Internal tide generation by tall ocean ridges 

      Echeverri Mondragon, Paula (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2009-09)
      Internal tides are internal waves of tidal period generated by tidal currents flowing over submarine topography. Tall ridges that are nominally two-dimensional (2-D) are sites of particularly strong generation. The ...

      Amrhein, Daniel E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2014-02)
      Observations suggest that during the last deglaciation (roughly 20,000-10,000 years ago) the Earth warmed substantially, global sea level rose approximately 100 meters in response to melting ice sheets and glaciers, and ...
