How Does Sound Travel in High Energy Environments? Effectiveness of Acoustic Monitoring Systems and Turbine Audibility Assessment

2020-12-10 OERA Webinar JASCO Martin
December 10, 2020 1:00pm – 2:00pm AST

Dr. Bruce Martin, JASCO Applied Sciences (Canada) Ltd

The researchers are designing and implementing a long-term acoustic monitoring program to support tidal energy development in the Bay of Fundy. Specialized acoustic instrumentation was deployed for a two-month period in Grand Passage to advance understanding how turbulence affects the ability to detect marine mammals, and to what extent these species can detect a tidal turbine. State-of-the-art hydrophones were deployed together with an active source that generates dolphin-like whistles and clicks. Soundscape data was collected during the instrument deployment period and is being modeled to measure how low-frequency sounds (e.g. dolphin clicks) propagate through turbulent waters. The modeling results will help infer how the turbulent flow impacts on the ability to detect the presence of marine life. 

The OERA webinar series is hosted in Zoom.
