On the use of time-frequency methods in a passive acoustic monitoring system

2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010
A modern method for discrete underwater channel characterization is the passive tomography concept which takes advantage of the generated signals by the natural sources (opportunity sources). The main difficulty which appears in this field is due to the lack of any information about the received signals.

Feeding behavior of wild dugongs monitored by a passive acoustical method

The Journal of the Acoustical Society of America, 2006
Little is known about feeding behavior of wild dugongs (Dugong dugon) because direct measurements of feeding events in the water were scarcely feasible. In this study, the authors achieved the first successful feeding sound monitoring in a seagrass area using a full-band underwater recording system (called automatic underwater sound monitoring system ...

Beta Testing of Persistent Passive Acoustic Monitors

2010
Abstract : Long-endurance oceanographic sampling platforms such as gliders and profiling floats provide a new opportunity for acquiring acoustic signals from marine animals with immediate applications in conservation and mitigation. Our objective is to produce a reliable system for persistent passive acoustic monitoring of marine animals.

The benefits and challenges of passive acoustic monitoring of fish

The Journal of the Acoustical Society of America, 2014
While is it widely known that numerous families of fish produce sound for communication, discerning when, where, and who is more difficult. Recent developments in passive acoustic technologies have facilitated marine bioacoustic studies to effectively monitor soniferous fishes.

Passive acoustic monitoring (putting it all together)

2011
After presenting the tools required to carry out PAM, the third part of this book discusses the operational aspect of how PAM may be used. PAM is a rather new direction in cetacean research, which so far has mostly been visually oriented. However, with the availability of affordable instrumentation and the increasing cost of human-operated ship-based ...
