Passive Acoustic Monitoring (PAM)
Passive acoustic monitoring is a technique that can be used to augment visual observations, greatly enhancing the likelihood of accurately detecting the presence of marine mammals in the vicinity of a seismic survey vessel or similar operation. Typical PAM systems are comprised of a short towed array of hydrophones spanning the full frequency range of cetacean species and a PC running software for the interpretation of acoustic data enabling species recognition and location estimation.
OceanEar is heavily involved with the development of the next generation of PAM system; in order to ensure that animals are accurately detected and located and that the deployment of the system has minimal impact upon survey operations.
