Passive acoustic listening has been shown to be very effective and environmental friendly for remotely monitoring marine mammals. However, for better identification and tracking performance, it is important to incorporate complete sound propagation physics in the localization process and related design of an optimal acoustic receiving array for use in the field.
We have developed an acoustics normal-mode, back-propagation approach and technology that enables us to monitor the movement of individual marine mammals that vocalize at low frequencies (< 1000Hz) over large ranges and time scales from a single mooring location. This April, we will examine and evaluate this passive acoustic localization approach in Cape Cod Bay when North American right whales are known to be present.
