    Cetacean–habitat modeling, although still in the early stages of development, represents a potentially powerful tool for predicting cetacean distributions and understanding the ecological processes determining these ...
  • Techniques for studying vocal learning in bottlenose dolphins, Tursiops truncatus 

    Fripp, Deborah R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1999-02)
    The objective of this thesis is to develop the methods necessary for evaluating the role of learning in the natural whistle development of bottlenose dolphins. Bottlenose dolphins provide a unique opportunity to study ...
  • Tectonic evolution and midplate volcanism in the South Pacific 

    Jordahl, Kelsey A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1999-02)
    Changes in morphology of the Marquesas Fracture Zone are correlated with small changes in Pacific-Farallon relative motion. The simple flexural signal of a locked fracture zone may be obscured by tectonic effects, and ...
  • The tectonic evolution of the North Central Caribbean plate margin

    The results of a detailed geophysical survey are used in conjunction with all available information in a study of the tectonic development of the Cayman Trough and the Greater Antilles Ridge. This development is connected ...
  • The tectonics and three-dimensional structure of spreading centers : microearthquake studies and tomographic inversions 

    Toomey, Douglas R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1987-09)
    Two-thirds of the Earth's surface has been formed along a global system of spreading centers that are presently manifested in several different structural forms, including the classic rift valley of the Mid-Atlantic ...
