Standard for acoustic metadata for passive acoustic monitoring

The Journal of the Acoustical Society of America, 2019
Passive 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, 2016
The 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), 2017
Anthropogenic 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), 2012
Cross-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 haddock in the Gulf of Maine

The Journal of the Acoustical Society of America, 2017
We 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.

Using passive acoustics for monitoring seagrass beds

OCEANS 2016 MTS/IEEE Monterey, 2016
This 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
