Fin whale calls observed with submarine cabled observatories off Kushiro-Tokachi during ten years

摘要

In this research, the automatically analyzation method which detect acoustic events such as fin whale calls and its locations is embedded in cable observatory system. This system has detection method about fin whale calls using spectrogram correlation, and the localization of fin whale calls using two hydrophones and a three-axis seismometer. This observation at off Kushiro-Tokachi has been continuously performed for more than 10 years. The detection and tracking analysis for fin whale calls are carried out about the archive data in parallel with the real-time data. The results of the past 10 years including the latest information is reported.
