Real time detection and localization system for underwater acoustic signal with cable observatories in the west Pacific Ocean

摘要

A previous research reported that the cable system off Kushiro-Tokachi was detected low frequency calls of fin whales. In this research, as an application using cable observatories about “development of remote species identification technologies for marine organisms”, we developed a real-time processing system for underwater acoustic signal with cable observatory. This paper reports the results of automatically detection and localization from continues observation using hydrophones and seismometers of the cable observatory. The applied system in cable observatories visualizes the number and position of fin whales.
