Broadband and statistical characterization of echoes from random scatterers : application to acoustic scattering by marine organisms
(Massachusetts Institute of Technology, 2013)
The interpretation of echoes collected by active remote-sensing systems, such as sonar and radar, is often ambiguous due to the complexities in the scattering processes involving the scatterers, the environment, and the ...
Hydrodynamics of a multiple tidal inlet system : Katama Bay, Martha's Vineyard, MA
(Massachusetts Institute of Technology, 2015)
Observations, theoretical models, and a numerical model (ADCIRC) are used to investigate the effects of tides, waves, bay bathymetry, and changing inlet geometry on the hydrodynamics of the multiple-inlet Katama system, ...
Passive wake detection using seal whisker-inspired sensing
(Massachusetts Institute of Technology, 2015)
This thesis is motivated by a series of biological experiments that display the harbor seal's extraordinary ability to track the wake of an object several seconds after it has swum by. They do so despite having auditory ...
Wave-, wind-, and tide-driven circulation at a well-mixed ocean inlet
(Massachusetts Institute of Technology, 2017)
The effects of waves, wind, and bathymetry on tidal and subtidal hydrodynamics at unstratified, shallow New River Inlet, NC, are evaluated using field observations and numerical simulations. Tidal flows are ebb-dominated ...
Effects of internal waves on low frequency, long range, acoustic propagation in the deep ocean
(Massachusetts Institute of Technology, 2007)
This thesis covers a comprehensive analysis of long-range, deep-ocean, low-frequency, sound propagation experimental results obtained from the North Pacific Ocean. The statistics of acoustic fields after propagation through ...
Laboratory evaluation of laser-induced breakdown spectroscopy (LIBS) as a new in situ chemical sensing technique for the deep ocean
(Massachusetts Institute of Technology, 2007)
Present-day expeditionary oceanography is beginning to shift from a focus on short-term ship and submersible deployments to an ocean observatory mode where long-term temporally-focused studies are feasible. As a result, a ...
