Acoustic Scattering from Compact Bubble Clouds.
Abstract : In this study, a simple model describing the low frequency scattering properties of high void fraction bubble clouds in both the free field and near the ocean surface is developed. ThisExpand

Evaluation of Relative Entropy for Distributed Passive Detection of Weak Acoustic Signals
Passive detection of weak signals in noise is formulated without assuming a parametric distribution of the received signal statistics. A binary likelihood-ratio test as to whether the probabilityExpand

Acoustic observations of internal tides and tidal currents in shallow water.
Significant acoustic travel-time variability and frequency shifts of acoustic intensity level curves in broadband signal spectrograms were measured in the East China Sea during the summer of 2008.Expand

Tower‐based breaking wave noise measurements
A tower‐based sea surface noise experiment began collecting data January 2006 in the shallow waters (25 m) approximately 75 km off the coast of Savannah, Georgia. A 32‐phone, three nested‐aperture,Expand
Acoustic recordings and modeling under seasonally varying sea ice
Acoustic data from the Canada Basin Acoustic Propagation Experiment are discussed. These recordings were obtained under seasonally varying sea ice to the north of Alaska during a period of 154 days.Expand

Breaking wave noise measurements at frequencies below 400 Hz
A sea surface noise experiment was conducted in shallow water (200 m) near San Clemente Island in March/April 1995 using a vertical array deployed from the RP/FLIP. Measurements of the time‐frequencyExpand

Combined passive acoustic and video monitoring of coral reefs to better understand reef soundscapes and multi-species interactions
A detailed understanding of ecological soundscapes provides a window into ecosystem state that might otherwise go undetected. Rather than consider acoustic emissions of a particular species, a topExpand
A real-time acoustic drifter for active and passive sonar applications
A low-cost, long-duration acoustic drifter has been developed to measure directional ambient noise and man-made acoustic signals in both shallow and deep oceans. Traditional acoustic andExpand
