Acoustic observation can complement visual observation to more effectively monitor occurrence and distribution of marine mammals. For effective acoustic censuses, calibration methods must be determined by joint visual and acoustic studies. Research is still needed in the field of acoustic species identification, particularly for smaller odontocetes ...

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.

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 ...

Passive acoustic monitoring (putting it all together)
2011After 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 ...

Passive acoustic monitoring of head disc interface interactions
Microsystem Technologies, 2009A hard disc drive (HDD) recording head thermal protrusion is monitored by the passive acoustic characterization technique where adaptive discrete wavelet (ADW) filtering has been introduced to declare the contact. A phenomenological model is built to demonstrate detectability of the passive acoustic monitoring.

Passive acoustics for monitoring bottom contact of dredge
2017 IEEE/OES Acoustics in Underwater Geosciences Symposium (RIO Acoustics), 2017In Argentina, stock assessment of Patagonian scallop (Zygochlamys patagonica) is carried out applying the swept area method using a dredge. Hence, for the accuracy of the biomass estimation contact of the dredge with the bottom is critical. Generally during these surveys the dredge contact with the bottom is determined by taking into account warp ...
