Dong Guk Paeng is a professor at Jeju National University. He was educated in Ocean Engineering at MIT for M.S. and Acoustics at Pennsylvania State University for Ph.D. He was a Research Associate in Biomedical Engineering at the University of Southern California, and a Research Associate Professor in Radiation Oncology at the University of Virginia during his sabbatical years. He was the 1st Merkin Fellow at Focused Ultrasound Foundation (FUSF) and has been an Asian Ambassador of FUSF since then. His current research interests are marine bioacoustics, diagnostic ultrasound of arterial blood flow and wall motion, and therapeutic ultrasound in applications of brain diseases such as Parkinson’s disease and Alzheimer’s disease. He published over 100 peer reviewed papers and book chapters.
Presentation title: Bioacoustic monitoring of Indo-Pacific Bottlenose Dolphins around Jeju Island
Abstract: Interest in marine bioacoustics is growing to better understand marine mammals and the ecosystems they inhabit. Approximately 120 to 150 Indo-Pacific bottlenose dolphins (Tursiops aduncus) are known to inhabit the waters surrounding Jeju Island. They use click sounds for echolocation and whistle sounds for communication. Machine learning techniques were employed to extract whistle sounds from the high ambient noise in the coastal waters of Jeju. Additionally, a bottlenose dolphin, previously held in captivity for 17 years for entertainment purposes, underwent in situ training to readapt to its native marine environment before release. Sound data from hydrophones installed at the site were synchronized with CCTV and drone surveillance to analyze interactions with wild bottlenose dolphins. This comprehensive approach sheds light on the complicated communicative behaviors of these marine mammals, contributing insights towards their conservation and understanding of them.
