  • Lima, Ana Lucia Cessel de (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2004-06)
    The most ubiquitous source of polycyclic aromatic hydrocarbons (PAHs) to the environment is incomplete combustion. This study generated a high-resolution historical record of pyrogenic PAH emissions since pre-industrial ...
  • Amaral-Zettler, Linda A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1996-09)
    The Acantharea and the Polycystinea are two classes of sarcodines (Sarcodina) which are exclusively planktonic and occur strictly in oligotrophic marine environments. Although these protists have been the topic of research ...
  • Waldbauer, Jacob R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2010-02)
    Biological activity has shaped the surface of the earth in numerous ways, but life’s most pervasive and persistent global impact has been the secular oxidation of the surface environment. Through primary production – the ...
  • Wurch, Louie L. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2011-09)
    Recurrent brown tide blooms caused by the harmful alga Aureococcus anophagefferens have decimated coastal ecosystems and shellfisheries along the Eastern U.S. and South Africa. The exact mechanisms controlling bloom ...
  • Passamaneck, Yale J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2003-09)
    DNA sequencing and phylogenetic analyses were conducted to investigate evolutionary relationships between taxa within the metazoan clade Lophotrochozoa. Chapter 1 presents an introduction to phylogenetics of the Metazoa ...
  • Kloepper-Sams, Pamela J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1988-12)
    Induction of the aryl hydrocarbon hydroxylase (AHH) P450IA1 occurs in many organisms following exposure to polycyclic aromatic hydrocarbons (PAH). Regulation of induction of P450IA 1 (called P-450E) was examined in the ...
  • Bryden, Harry L. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1975-07)
    The local dynamics of low-frequency motions in the MODE region are investigated from three arrays of moored measurements of current and temperature. Tests for lowest-order balances of horizontal momentum, mass, heat, heat ...
  • Sweeney, Erin N. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2001-05)
    A comparison of monthly biogeochemical measurements made from 1993 to 1995, combined with hydrography and satellite altimetry, was used to observe the impacts of nine eddy events on primary productivity and particle flux ...
  • von Appen, Wilken-Jon (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2013-02)
    Two high-resolution mooring arrays extending from the outer shelf to the mid continental slope are used to elucidate shelf-basin exchange at the inflow to and the outflow from the Arctic Ocean. Pacific Water entering the ...
  • Marsh, Sarah Elizabeth (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2001-08)
    Pinniped (seal and sea lion) auditory systems operate in two acoustically distinct environments, air and water. Piniped species differ in how much time they typically spend in water. They therefore offer an exceptional ...
  • Gularte, Ronald Carl (Woods Hole Oceanographic Institution, 1972-05)
    A portable gas chromatograph, using a single flame ionization detector, was constructed. The unit was tested for response to surge, sway and heave accelerations up to 0.3g. Also the detector's response was studied for ...
  • Briggs, Michael Jeffrey (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1981-06)
    The multichannel Maximum Entropy Method (MEM) of spectral analysis is developed and applied in the dynamic analysis of offshore structures. Two different algorithms are implemented and compared with the conventional ...
  • Wortham, Cimarron J. L. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2013-02)
    Efforts to monitor the ocean for signs of climate change are hampered by ever-present noise, in the form of stochastic ocean variability, and detailed knowledge of the character of this noise is necessary for estimating ...
  • Primeau, Francois W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1998-06)
    The steady states of two models of the double-gyre wind-driven ocean circulation are studied. The link between the steady state solutions of the models and their time-mean and low-frequency variability is explored to ...
  • Stewart, W. Kenneth (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1988-07-05)
    This thesis develops an approach to the construction of multidimensional stochastic models for intelligent systems exploring an underwater environment. The important characteristics shared by such applications are: ...
  • Kuo, Alan J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1994-12)
    The marine symbiotic bacterium Vibrio fischeri is striking for its ability both to emit light and to dramatically regulate light emission using a cell-to-cell signalling mechanism called autoinduction. The latter is ...
  • 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 ...
  • Griffith, David R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2013-09)
    Steroidal estrogens are potent endocrine disrupting chemicals that are naturally excreted by vertebrates (e.g., humans and fish) and can enter natural waters through the discharge of treated and raw sewage. Because ...
  • Shih, John Shai-Fu (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1979-12)
    Bathymetric profiles of mid-ocean ridges show that the morphology of ridge crests and the roughness of sea-floor relief created there is commonly related to the spreading rate. To study the creation of fine-scale sea-floor ...
  • Johnson, Gregory C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1990-09)
    Theory and observations of deep circulation in the near-equatorial Atlantic, Indian and Pacific Oceans are reviewed. Flow of deep and bottom water in the near-equatorial Indian and Pacific oceans, the two oceans with ...
