  • Bayer, Skylar R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2011-06)
    The colonization dynamics and life histories of pioneer species are vital components in understanding the early succession of nascent hydrothermal vents. The reproductive ecology of pioneer species at deep-sea hydrothermal ...
  • Rodenbusch, George (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1978-08)
    A linearized theory for the response of a circular pendulum spar in 2-dimensional waves and a uniform current is developed. The linear forces on the cylinder are predicted using an approximate potential flow theory for ...
  • Zhai, Ping (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2011-09)
    Remote sensing and in situ observations are used to investigate the ocean response to the Tokar Wind Jet in the Red Sea. The wind jet blows down the pressure gradient through the Tokar Gap on the Sudanese coast, at about ...
  • Escartin Guiral, Javier E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1996-08)
    Two-thirds of the Earth's surface is oceanic crust formed by magmatic and tectonic processes along mid-ocean ridges. Slow-spreading ridges, such as the Mid-Atlantic Ridge, are discontinuous and composed of ridge segments. ...
  • Harrington, Stephanie A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1997-06)
    Second-class wave propagation along mid-ocean ridges is investigated in an effort to explain subinertial peaks found in the velocity spectra over the Juan de Fuca Ridge (JdFR, 4 days) and the Iceland-Faeroe Ridge (IFR, ...
  • Gieleghem, Ryan T. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2012-09)
    Signal detection and synchronization in the time varying ocean environment is a difficult endeavor. The current common methods include using a linear frequency modulated chirped pulse or maximal length sequence as a detection ...
  • Sigman, Daniel M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1997-09)
    This dissertation contributes to the search for a cause of glacial/interglacial variations in atmospheric carbon dioxide. The hypotheses addressed involve changes in low and high-latitude biological export production. A ...
  • Brownawell, Bruce J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1986-04)
    Polychlorinated biphenyls (PCBs) were used as model hydrophobic organic compounds (HOC) to study physical~chemical processes which affect the speciation and fate of HOC in coastal environments. The focus of this study ...
  • Hamersley, Michael R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2001-12)
    I used direct measurements of nitrogen gas (N2) fluxes and a 15N stable isotope tracer to determine the contribution of denitrification to salt marsh sediment N cycling. Denitrification in salt marsh tidal creekbottoms ...
  • Caron, David A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1984-06)
    The distribution and feeding behavior of bacterivorous micro flagellates (2-20 μm protozoa) and their ingestion by copepods were examined in an attempt to assess the importance of these protozoa as a trophic link ...
  • Howarth, Robert W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1979-02)
    The rate of sulfate reduction in stands of dwarf Spartina alterniflora in the Great Sippewissett Salt Marsh is approximately 75 moles S04 m2 year-1. This is the highest rate reported for any natural ecosystem. Sulfate ...
  • Park, Young-Gyu (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1996-09)
    A convection experiment was done with a rotating rectangular tank as a model of oceanic meridional overturning circulation. Heat flux was fixed at one bottom end of the tank using an electrical heater. Temperature was ...
  • Halliday, Elizabeth (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2012-09)
    The marine fecal indicator Enterococcus is measured at beaches to detect fecal contamination events, and beaches are closed to bathers when Enterococcus is found to exceed the federally mandated limit. This dissertation ...
  • Wolfteich, Carl M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1994-02)
    Planktonic foraminiferal flux was collected at four sediment trap locations spanning a 34° latitude range in the North Atlantic during 1988-1990. Satellite-derived sea surface temperature (SST) and CTD data were integrated ...
  • Green, Rebecca E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2002-06)
    Predictions of chlorophyll concentration from satellite ocean color are an indicator of phytoplankton primary productivity, with implications for foodweb structure, fisheries, and the global carbon cycle. Current models ...
  • Wilkin, John L. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1988-09)
    A study is conducted of the scattering of freely-propagating subinertial frequency coastal-trapped waves (CTWS) by large variations in coastline and topography using analytical and numerical techniques. Particular attention ...
  • Bowers, Colleen Marie (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2006-09)
    Recent studies have shown that the presence of sand ripples on the seabed improves sonar detection of buried mines at sub-critical angles. Sidescan sonar data of ripples on the west Florida shelf were collected as part ...
  • Collins, John A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1988-10-06)
    The results of numerous seismic refraction and reflection experiments have shown that the seismic structure of the oceanic crust can be usefully parameterized by a small number of locally horizontal layers within which ...
  • Burian, Erik A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1996-07-18)
    The continuing development of the autonomous underwater vehicle as an oceanographic research tool has opened up the realm of scientific possibility in the field of deep ocean research. The ability of a vehicle to travel ...
  • Rykova, Tatiana A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2010-06)
    The Labrador Sea, as one of a few places of deep water formation, plays an important role in the Meridional Overturning Circulation. While the interior of the Labrador Sea, where the deepest convection takes place, is ...
