5203 |a"To respond to the needs of continuously monitoring North Atlantic Right Whales (NARW) in real time over large areas of the Gulf of St. Lawrence, performance studies using simulations of in situ conditions have concluded that the optimal passive acoustic monitoring (PAM) systems were large circular hydrophone arrays. To accomplish this PAM challenge and position the whales in their habitat, two prototypes of such circular hydrophone arrays, 20 m in diameter, were designed, built, and tested off the Gaspé peninsula in the summer of 2021. This report presents the characteristics of this new PAM technology, used for the first time to track low frequency calling whales over large-scale sensitive areas of their habitats. These large apparatus were positioned on the seafloor, at significant distances from the coast, and depths exceeding human diver ranges. The deployment techniques, involving coordinated boats, are detailed. The approach used is discussed and recommendations for further improvements are provided. Examples of preliminary results confirming the performance studies are presented for several species of baleen whales and a transiting merchant ship. Further steps for real-time implementation will be detailed in further contributions from this research project "--Abstract, page vi.
