Technology & Innovation

Effective monitoring of mitigation zones is essential to minimise impacts to marine mammals, reduce unnecessary delays to activities and ensure regulatory compliance. However, designing effective systems is challenging, particularly where mitigation zones are large. We describe a passive acoustic monitoring (PAM) buoy system with real-time detection, classification and localisation capabilities and present a system validation case study. This includes a tool to optimise performance, considering the influence of detection range, ambient noise and instrument configurations. This tool provides a means for effective PAM system design in advance of operations, to help to provide confidence to regulators and clients
