Acoustics of Pelagic Fish Schools”
Prof. Thomas R. Hahn, PhD

For many decades, acoustics has proven to be the remote sensing technique of choice in assessing fish over multiple spatial and temporal scales. Commonly employed high-frequency fisheries acoustic techniques, as implemented in commercial and scientific fish finding sonars, allow biomass estimation based on known scattering characteristics of the target species but suffer from a series of economic and scientific limitations. More recently, applications of low-frequency acoustic methods have received much attention in the community. These techniques probe the dynamics of fish schools at larger ranges and potentially allow unique insights into the physics and biology of these targets. The author will, from a physics perspective, present a series of theoretical and practical developments in active and passive low-frequency acoustics of pelagic fish, and help explore applications to Great Lakes research.
