Lecture Title: Passive Acoustic Monitoring for Marine Biodiversity and Arctic Climate Change Studies.
The event kicked off with a warm welcome from Prof. V. Sriram, Chair of IEEE OES Madras Chapter, followed by an introduction to our esteemed speaker by Mr. Sridhar Krishnamoorthy, Chair of IEEE OES IIT Madras Student Branch Chapter.
About the Speaker:
Dr. Hari Vishnu, a distinguished Senior Research Fellow at the Acoustic Research Laboratory, National University of Singapore, specializes in underwater acoustic signal detection and localization. He earned his Ph.D. from Nanyang Technological University and has since made significant contributions to the fields of machine learning for underwater applications, bio-acoustics, and signal processing in impulsive noise. His work spans various underwater scenarios, from biodiversity studies and defense applications in tropical waters to mineral exploration and Arctic ice sheet research. Dr. Vishnu has also served as a Visiting Scholar at the Scripps Institution of Oceanography and is the current Chief Editor of the IEEE Oceanic Engineering Society’s magazine, Earthzine, as well as the society’s Secretary.
Dr. Vishnu’s captivating lecture delved into the fascinating world of passive acoustic monitoring (PAM), highlighting its crucial applications:
Marine Mammal Monitoring:
Dr. Vishnu discussed the monitoring of marine mammals, such as dolphins, in Singapore waters through their vocalizations, which are vital for foraging, navigation, and communication. He explained the development of a machine-learning-based PAM system designed to handle the unique challenges of Singapore’s noise environment, including biological and shipping noise. This system helps detect and quantify marine mammals amidst complex acoustic backgrounds.
Climate Change and Glacial Studies:
The second part of the lecture focused on utilizing PAM to study climate-induced ice-loss mechanisms at marine-terminating glaciers in the Arctic and Antarctic. Dr. Vishnu highlighted the importance of remote sensing in these hazardous and inaccessible regions to understand glacier melt activity and the challenges faced in this endeavor.
The lecture was truly enriching, highlighting innovative applications of passive acoustics in marine biodiversity and climate change research. Students and research scholars engaged in a stimulating interaction with the speaker, fostering insightful discussions. We eagerly anticipate organizing more thought-provoking events like this in the future.
The session was followed by a detailed Q&A session in which both faculties and students participated.
Prof. S. Nallayarasu, Head of the Department, presented our esteemed speaker with a commemorative memento, acknowledging the lecture’s profound impact on ocean engineering. He expressed his strong support for such student-led initiatives within our institute.
