Performance bounds on matched-field methods for source localization and estimation of ocean environmental parameters
(Massachusetts Institute of Technology, 2001)
Matched-field methods concern estimation of source location and/or ocean environmental parameters by exploiting full wave modeling of acoustic waveguide propagation. Typical estimation performance demonstrates two fundamental ...
Relating behavioral context to acoustic parameters of bottlenose dolphin (Tursiops truncatus) vocalizations
(Massachusetts Institute of Technology, 2001)
This thesis presents methods to analyze the function of vocalizations of the bottlenose dolphin, Tursiops truncatus. The thesis uses the social interaction as the basic unit of analysis, and maintains a deliberate focus ...
Experimental visualization of the near-boundary hydrodynamics about fish-like swimming bodies
(Massachusetts Institute of Technology, 2001)
This thesis takes a look at the near boundary flow about fish-like swimming bodies. Experiments were performed up to Reynolds number 106 using laser Doppler velocimetry and particle imaging techniques. The turbulence in ...
Physiological and behavioral diagnostics of nitrogen limitation for the toxic dinoflagellate Alexandrium fundyense
(Massachusetts Institute of Technology, 2001)
Interactions between mantle plumes and mid-ocean ridges : constraints from geophysics, geochemistry, and geodynamical modeling
(Massachusetts Institute of Technology, 2001)
This thesis studies interactions between mid-ocean ridges and mantle plumes using geophysics, geochemistry, and geodynamical modeling. Chapter 1 investigates the effects of the Marion and Bouvet hotspots on the ultra-slow ...
The aggregation of clay minerals and marine microalgal cells : physicochemical theory and implications for controlling harmful algal blooms
(Massachusetts Institute of Technology, 2001)
In recent years, the use of clay minerals has emerged as one of the most promising strategies for directly controlling harmful algal blooms (HABs). Its principle is based on the mutual aggregation of algal cells and mineral ...
Estimating Gulf of Maine zooplankton distributions using multiple frequency acoustic, video and environmental data
(Massachusetts Institute of Technology, 2001)
This thesis develops methods useful for estimating zooplankton distributions in the field by combining acoustic scattering models and an integrated set of field data. The accuracy of existing scattering models for fluid-like ...
