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 there are dolphin in the specific area and using unmanned
載具整 合之研 究 水面無人 聲學監 被動水下 慧型 測與智 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.

Keywords: Passive acoustic monitoring, unmanned surface vehicle, real-time
whistle detector, MOOS-IvP
