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 ...
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 ...
Advances in integrating autonomy with acoustic communications for intelligent networks of marine robots
(Massachusetts Institute of Technology, 2013)
Autonomous marine vehicles are increasingly used in clusters for an array of oceanographic tasks. The effectiveness of this collaboration is often limited by communications: throughput, latency, and ease of reconfiguration. ...
Uncertainty Quantification in ocean state estimation
(Massachusetts Institute of Technology, 2013)
Quantifying uncertainty and error bounds is a key outstanding challenge in ocean state estimation and climate research. It is particularly difficult due to the large dimensionality of this nonlinear estimation problem and ...
