Standard for acoustic metadata for passive acoustic monitoring
The Journal of the Acoustical Society of America, 2019Passive acoustic monitoring often relies on data collected with various instrumentation, by multiple research groups in different locations, under diverse conditions, and with a variety of data analysis methods. To make the output comparable and to preserve data for long time-series analysis, metadata needs to be reported in a standardized way.

Harbor passive acoustic monitoring systems
Journal of the Acoustical Society of America, 2016The feasibility of detecting quiet moving targets (e.g., unmanned undersea vehicles) in harsh harbor environments by using passive acoustic bottom-mounted hydrophone arrays, combined with advanced signal processing detection systems tuned to the target’s radiated noise signature characteristics is presented.

On the detection of impulsive and tonal events in passive acoustics monitoring
2017 22nd International Conference on Digital Signal Processing (DSP), 2017Anthropogenic underwater sound is now recognized as a world-wide problem. Shipping, seismic surveys and pile driving, among some other human activities, have shown a broad range of negative effects in a variety of species. It is thus important to control, register and characterize these activities in order to establish policies that mitigate its ...

Passive acoustic monitoring using random matrix theory
2012 IEEE Statistical Signal Processing Workshop (SSP), 2012Cross-correlating ocean noise is a potential alternative to using active sources to monitor and study ocean environments. However, directional sources in the medium (usually ships) often introduce a bias in the cross-correlations, making the travel time estimates unreliable. Here, we use recent results in random matrix theory for the eigenvalue density

Passive Acoustic Monitoring of Surface Vessel Activity
Volume 4: Ocean Engineering; Ocean Renewable Energy; Ocean Space Utilization, Parts A and B, 2009Monitoring human activity in remote marine areas is a challenging problem to which acoustic methods present a promising solution. This paper develops and demonstrates automated passive acoustic methods to estimate ranges to surface vessels using a single seafloor-mounted hydrophone.

Passive acoustic monitoring of haddock in the Gulf of Maine
The Journal of the Acoustical Society of America, 2017We have conducted several studies of haddock sounds in the Gulf of Maine (GOM) with mixed results. An analysis of an archival recording from captive haddock brood stock made in 1970 found that the “spawning rumble” sound occurred variously at the end of short thump trains, in the middle of thump trains, or in isolation.

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 ...
