Abstract:
In the past, the measurement of underwater noise in the surrounding waters of Taiwan and the passive acoustic monitoring of marine mammals were conducted by the commissioning units in accordance with their business and financial resources. Lack of long-term and extensive investigations, the acoustic database and the complete system have not been established, which has caused the complexity of the use of related resources. Thus, we hope we can build a passive acoustic monitoring network in the near future, measure and analyze the ocean soundscape, and evaluate the information in the marine environment. It has the necessity and positive benefits for marine conservation, and the results will serve as the basis for the establishment of underwater noise and passive acoustic monitoring networks in the surrounding waters of Taiwan. This article provides a process for checking if here are dolphin in the specific area and using unmanned surface vehicle to track the source and find the area they are. This process has 4 main parts, including real-time dolphin whistle detection, real-time shore side monitoring system, underwater acoustic source localization and the behavior of the surface vehicle.
