Passive Acoustic Monitoring of Cetaceans
2011Passive acoustic monitoring is increasingly used by the scientific community to study, survey and census marine mammals, especially cetaceans, many of which are easier to hear than to see. PAM is also used to support efforts to mitigate potential negative effects of human activities such as ship traffic, military and civilian sonar and offshore ...

The possibility of passive acoustic monitoring of a Scuba Diver
Doklady Earth Sciences, 2016The problem of controlling the state and location of scuba divers is of importance. This work consider the possibility to use for this purpose a low-frequency noise of a scuba diver. The noise of a scuba diver under a dry swimming suite near the trachea and in the water at a distance of 50 m was recorded.It wa shown that both sygnals are characterized ...

Using passive acoustics for monitoring seagrass beds
OCEANS 2016 MTS/IEEE Monterey, 2016This paper discusses the ambient noise acquired during the period of one week, from May 8 to 15, 2013 over a Posidonia oceanica bed in the Bay of la Revellata, Calvi, Corsica. The acoustic receivers were moored at 3 locations with water depth ranging from 2 to 20 m. Simultaneously with acoustic measurements, the dissolved O2 was measured by an array of

Glider-Based Passive Acoustic Monitoring in the Arctic
Marine Technology Society Journal, 2014AbstractPersistently poor weather in the Arctic makes traditional marine mammal research from aircraft and ships difficult, yet collecting information on marine mammal distribution and habitat utilization is vital for understanding the impact of climate change on Arctic ecosystems.

Passive Acoustic Detection and Monitoring of Schools of Herring
The Journal of the Acoustical Society of America, 2008Passive acoustic detection and monitoring of various marine fishes has recently received much attention in the literature. It has been recognized that passive acoustic techniques have the potential to complement traditional active acoustic surveys and to significantly increase their overall efficiency, if the acoustic signatures of the considered ...

Beta Testing of Persistent Passive Acoustic Monitors
2010Abstract : 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.

On the use of time-frequency methods in a passive acoustic monitoring system
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010A 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.

The benefits and challenges of passive acoustic monitoring of fish
The Journal of the Acoustical Society of America, 2014While 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.
