    • Insights into vitamin B12 production, acquisition, and use by marine microbes 

      Bertrand, Erin M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2012-02)
      The distribution and magnitude of marine primary production helps determine the ocean's role in global carbon cycling. Constraining factors that impact this productivity and elucidating selective pressures that drive the ...
    • Mechanisms of metal release from contaminated coastal sediments 

      Kalnejais, Linda H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2005-09)
      The fate of trace metals in contaminated coastal sediments is poorly understood, yet critical for effective coastal management. The aim of this thesis is to investigate and quantify the mechanisms leading to the release ...
    • N2 fixation by subsurface populations of Trichodesmium : an important source of new nitrogen to the North Atlantic Ocean 

      Heithoff, Abigail (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2011-02)
      Trichodesmium, a genus of diazotrophic cyanobacteria, is an important contributor to the marine nitrogen (N) and carbon (C) cycles. The extent to which Trichodesmium dinitrogen (N2) fixation contributes to the marine N ...
    • Probabilistic evaluation of tankship damage in collision events 

      Crake, Kurtis W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1998-06)
      An analytical method for precidicting the extent of damage in ship collisions is developed. The method calculates both the longitudinal and transverse extents of damage for the struck ship as a function of collision ...
    • Seismic scattering of low-grazing-angle acoustic waves incident on the seafloor 

      Greaves, Robert J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1998-06)
      The goal of this thesis is to develop a methodology to interpret sound scattered from the seafloor in terms of seafloor structure and subseafloor geological properties. Specifically, this work has been directed towards ...
