NANTES, France – Sercel has launched QuietSea, its new passive acoustic monitoring (PAM) system designed to detect the presence of marine mammals during seismic operations.
Unlike other separate antenna PAM systems, Sercel says QuietSea is seamlessly integrated as an add-on within the Sercel Sentinel seismic streamer (Sentinel, Sentinel RD, and Sentinel MS). This allows for enhanced marine mammal detection capabilities in a wide frequency listening range that covers a large variety of vocalizing cetacean species. QuietSea also benefits from synergies with Sercel’s Seal 428 marine seismic recorder and SeaPro Nav navigation system to accurately locate marine mammal positions.
While enabling marine seismic contractors to comply with marine mammal monitoring regulations worldwide, QuietSea also helps to optimize the productivity of marine seismic operations. QuietSea’s integrated architecture allows for easy and safe deployment.
QuietSea is a tool for complementing the work of marine mammal observers (MMOs) during seismic operations. Its patented advanced and automated mammal detection and localization algorithms provide an additional, objective source of information for decision-making, particularly during night-time operations.
