CSA Deploys Real-Time Automated Sound Detecting System

On Tuesday, 2 July 2013, CSA Ocean Sciences Inc. (CSA) successfully deployed a real-time automated system that immediately displays the continuous spectrogram of a live audio stream to an interactive website.  In addition to the acoustic data stream, various sound monitoring analyses are readily available on the website.

Together, CSA, SeaRobotics Corporation, and members of the Technical University of Catalonia, BarcelonaTech (Spain) have linked the autonomous platform onboard automated acoustic monitoring system to the Internet from the SeaRobotics facility in Stuart, Florida, thus creating a live connection between subsea data acquisition and a user’s desktop via an un-cabled, unmanned observatory.  The resulting data can be monitored online via CSA’s website is a unique web-based real-time PAM application available for the offshore industry, anticipating the future broad use of acoustic data at large spatial and temporal scales.  This unique approach provides the opportunity for a significant impact on how applied acoustic-based research is currently conducted. is designed for ease of operation (non-expert) and provides a monitoring system that operates 24/7 continuously, automatically, and without the need for post processing.

CSA’s vision is to provide solutions that far exceed current acoustic monitoring technology, increase and highlight the benefit of acoustic measurements, and demonstrate industries’ concern for the marine environment.
