Underwater Acoustics
Marine bioacoustics and underwater sound source localization
Overview
Our underwater acoustics research spans two independent directions: marine bioacoustics and underwater sound source localization.
Marine Bioacoustics
We acoustically monitor Indo-Pacific bottlenose dolphins (Tursiops aduncus) around Jeju Island using long-term passive hydrophone recordings. Dolphin whistles are automatically detected with deep-learning detectors and analyzed to build whistle repertoires and identify signature whistles, and to compare vocal patterns across populations. This work also extends to photo-identification of individuals from dorsal fins and to multi-modal monitoring (acoustic, CCTV, and drone) of interactions between wild and rehabilitating dolphins.
