Passive Acoustic Monitoring

Working alongside MMO’s, Passive Acoustic Monitoring (PAM) Operators use static or towed hydrophones and real-time monitoring software to detect marine mammals acoustically during industrial operations. Use of PAM is not always compulsory, but New Zealand’s Seismic Code stipulates that two PAM Operators must be present during Level 1 seismic surveys. Incorporation of PAM technology is becoming increasingly more common in other areas as well. OSC-NZ caters for all your PAM needs including logistics, equipment and Operators.

OSC-NZ’s PAM systems are configured with the latest versions of PAMGuard software, and they meet all the necessary requirements for New Zealand and the Asia-Pacific region, including the ability to detect high-frequency cetaceans such as Hector’s and Maui’s dolphins.

OSC-NZ PAM Operators are DOC accredited, knowledgeable, and well equipped to deal with issues that may arise in the field, which is particularly advantageous when implementing the New Zealand Seismic Code, as breaks in PAM exceeding two hours can prevent operations continuing. All our PAM Operators have an understanding of acoustics and marine mammal vocalisations, which coupled with the ability to optimise PAM set-up for the area they are working, gives them the best chance of detecting marine mammals.

All our systems are dispatched with 100% redundancy.
