  • Pascual-Dunlap, Maria M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1995-06)
    In marine ecology, the variability of the physical environment is often considered a main determinant of biological pattern. A common approach to identifying key environmental forcings is to match scales of variability: ...
  • Sikora, Joseph J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2005-09)
    This thesis develops and utilizes a method for analyzing data from the North Pacific Acoustic Laboratory's (NPAL) Basin Acoustic Seamount Scattering Experiment (BASSEX). BASSEX was designed to provide data to support the ...
  • DiPerna, Daniel T. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1993-10)
    This thesis investigates a new method for predicting the farfield scattered pressure of a plane wave due to an infinite cylinder of noncircular cross section. Both impenetrable and penetrable :fluid boundary condi tions ...
  • Nowacek, Douglas P. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1999-09)
    Odontocetes are assumed to use echolocation for navigation and foraging, but neither of these uses of biosonar has been conclusively demonstrated in free-ranging animals. Many bats are known to use echolocation throughout ...
  • Mazloff, Matthew R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2008-09)
    A modern general circulation model of the Southern Ocean with one-sixth of a degree resolution is optimized to the observed ocean in a weighted least squares sense. Convergence to the state estimate solution is carried ...
  • Zang, Xiaoyun (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1998-01-18)
    We have contrived a regional model Φ(K, ω, η, φ, λ) for the distribution of low frequency variability energy in horizontal wavenumber, frequency, vertical mode and geography. We assume horizontal isotropy, Φ(K, ω, η, φ, ...
  • Walter, Matthew R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2008-02)
    This thesis formulates an estimation framework for Simultaneous Localization and Mapping (SLAM) that addresses the problem of scalability in large environments. We describe an estimation-theoretic algorithm that achieves ...
  • Cheney, Jerry (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1982-08)
    Zooplankton samples were collected with the MOCNESS (Multiple Opening/ Closing Net and Environmental Sensing System) on six cruises in the western North Atlantic Ocean during the period from August 1975 to November 1977 ...
  • Fusaro, Abigail Jean (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2008-09)
    Ecological processes at deep-sea hydrothermal vents on fast-spreading mid-ocean ridges are punctuated by frequent physical disturbance. Larval dispersal among disjunct vent sites facilitates the persistence of sessile ...
  • Engel, Patricia Ann (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2009-09)
    Mechanisms for the tidal component of salt flux in the Hudson River estuary are investigated using a 3D numerical model. Variations with river discharge, fortnightly tidal forcing, and along channel variability are ...
  • Hill, M. Forrest (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2000-09)
    The distribution of organisms in space has important consequences for the function and structure of ecological systems. Such distributions are often referred to as patchy, and a patch-based approach to modeling ecosystem ...
  • Thompson, Christine M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2011-02)
    Larval supply is an important process linking reproductive output to recruitment of benthic marine invertebrates. Few species-specific studies of bivalve larvae have been performed due to the lack of suitable methods for ...
  • Zang, Xiaoyun (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2000-02)
    A simple dynamic model is used with various observations to provide an approximate spectral description of low frequency oceanic variability. Such a spectrum has wide application in oceanography, including the optimal ...
  • Zhang, Yanwu (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2000-06)
    The thesis develops and demonstrates methods of classifying ocean processes using an underwater moving platform such as an Autonomous Underwater Vehicle (AUV). The "mingled spectrum principle" is established which concisely ...
  • Barth, John A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1987-10)
    A two-layer shallow water equation model is used to investigate the linear stability of a coastal upwelling front. The model features a surface front near a coastal boundary and bottom topography which is an arbitrary ...
  • Hristova, Hristina G. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2009-06)
    My thesis covers two general circulation problems that involve the stability of largescale oceanic flows and the importance of non-local effects. The first problem examines the stability of meridional boundary currents, ...
  • Libes, Susan M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1983-01)
    Isotope studies of nitrogen and carbon were undertaken to investigate the fate of particulate organic matter (POM) during its residence in the water column and after deposition on the seafloor. The processes focused on ...
  • Goldner, Daniel R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1998-06)
    Efforts to understand the Arctic system have recently focused on the role in local and global circulation of waters from the Arctic shelf seas. In this study, steady-state exchanges between the Arctic shelves and the ...
  • Singleton, Thomas W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1995-09)
    This thesis describes the steps necessary to develop an acoustic vorticity meter for the atmosphere. The analysis is based on Benthic Acoustic Stress Sensor (BASS) technology that is currently used for similar acoustic ...
  • Jakuba, Michael V. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2007-02)
    This thesis presents a stochastic mapping framework for autonomous robotic chemical plume source localization in environments with multiple sources. Potential applications for robotic chemical plume source localization ...
