Verification of a six-degree of freedom simulation model for the REMUS autonomous underwater vehicle
(Massachusetts Institute of Technology, 2001)
mproving the performance of modular, low-cost autonomous underwater vehicles (AUVs) in such applications as long-range oceanographic survey, autonomous docking, and shallow-water mine countermeasures requires improving the ...
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 ...
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 ...
Evaluation of transport relative to the tidal mixing front on Southern Georges Bank
(Massachusetts Institute of Technology, 2001)
As part of Phase III of the U.S. GLOBEC Georges Bank program, drogued drifters and dye tracer were released into the pycnocline on the southern flank of Georges Bank to measure advective and diffusive transport relative ...
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 ...
