Swarming in Shallow Waters

An Oil Fate Model for Shallow-Waters

We introduce a model for the dynamics of oil in suspension, appropriate for shallow waters, including the nearshore environment. This model is capable of oil mass conservation and does so by evolving the oil on the sea surface as well as the oil in the subsurface. The shallower portion of the continental shelf poses compounding unique modeling challenges. Many of these relate to the complex nat...

Predictions of Time Reversing Array Performance in Shallow Ocean Waters

The long term goals of this project are: i) to predict and understand the characteristics of active and passive time reversing array (TRA) performance in shallow water ocean waters, ii) to deduce the effectiveness of using a TRA for underwater communication and for surveillance of the acoustic characteristics of known or unknown environments, and iii) to determine how to exploit the generic pro...

Light in shallow waters: A brief research review

Until recently, optical processes in shallow water, where a large portion of solar photons penetrate to the ocean floor, has received little attention outside of a relatively small number of modeling and remote sensing investigations. In the open ocean, scales of variability in relation to optical attenuation length often permit the treatment of the inwater light field as a one-dimensional, dep...

Predicting Time Reversing Array Performance in Shallow Ocean Waters

This project seeks to quantitatively predict TRA performance in shallow ocean environments. Here performance includes: retrofocus field amplitude, location, size, and longevity; and the correlation of the retrofocused signal with the original signal. The intent is to predict these quantities as a function of signal frequency and bandwidth, source-array range, array orientation, noise level, sou...
