    • Modeling wind forcing in phase resolving simulation of nonlinear wind waves 

      Kalmikov, Alexander G. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2010-02)
      Wind waves in the ocean are a product of complex interaction of turbulent air flow with gravity driven water surface. The coupling is strong and the waves are non-stationary, irregular and highly nonlinear, which restricts ...

      Slowey, Niall C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1990-09)
      As a primary feature of ocean circulation and a key component of the global carbon cycle, changes in the thermocline must be accounted for if we are to understand the processes involved in Quaternary climatic fluctuation. ...

      The modern depositional environment of the northern epicontinental Barents Sea varies from proximal to distal glaciomarine. The regional surface sediment distribution is controlled by erosion of shallow banks of the ...
    • Molecular and isotopic records of combustion inputs to the environment over the last 250 years 

      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 ...
    • A molecular approach to questions in the phylogeny of planktonic sarcodines 

      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 ...
    • Molecular biogeochemistry of modern and ancient marine microbes 

      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 ...
    • Molecular determination of marine iron ligands by mass spectrometry 

      Boiteau, Rene M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-02)
      Marine microbes produce a wide variety of metal binding organic ligands that regulate the solubility and availability of biologically important metals such as iron, copper, cobalt, and zinc. In marine environments where ...
    • Molecular insights into the niche of harmful brown tides 

      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 ...
    • Molecular phylogenetics of the Metazoan clade Lophotrochozoa 

      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 ...
    • Molecular regulation of the induction of cytochrome P-450E in the estuarine fish Fundulus heteroclitus 

      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 ...
    • Momentum, mass, heat, and vorticity balances from oceanic measurements of current and temperature 

      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 ...
