Computational imaging and automated identification for aqueous environments
(Massachusetts Institute of Technology, 2011)
Sampling the vast volumes of the ocean requires tools capable of observing from a distance while retaining detail necessary for biology and ecology, ideal for optical methods. Algorithms that work with existing SeaBED AUV ...
Three-dimensional acoustic propagation through shallow water internal, surface gravity and bottom sediment waves
(Massachusetts Institute of Technology, 2011)
This thesis describes the physics of fully three-dimensional low frequency acoustic interaction with internal waves, bottom sediment waves and surface swell waves that are often observed in shallow waters and on continental ...
Understanding and utilizing waveguide invariant range-frequency striations in ocean acoustic waveguides
(Massachusetts Institute of Technology, 2011)
Much of the recent research in ocean acoustics has focused on developing methods to exploit the effects that the sea surface and seafloor have on acoustic propagation. Many of those methods require detailed knowledge of ...
Performance analysis for lateral-line-inspired sensor arrays
(Massachusetts Institute of Technology, 2011)
The lateral line is a critical component of the fish sensory system, found to affect numerous aspects of behavior including maneuvering in complex fluid environments, schooling, prey tracking, and environment mapping. This ...
