Dr. Ross Chapman, School of Earth and Ocean Sciences, UVic 'A career in ocean acoustics in Canada' (Cosponsored by the IEEE OES Victoria Chapter)
Dr. Ross Chapman is recognized for his research on acoustic propagation modeling in the ocean and the interaction of sound with the ocean bottom. His work has fundamental importance in understanding the physics of sound propagation in marine sediments, and in applications for acoustic characterization of sea bottom materials and sonar performance prediction. Acousticians describe the interaction of sound with the ocean bottom by geoacoustic models, profiles of the depth variation of physical properties such as sound speed, that are used as inputs to numerical calculations of the acoustic field.
Dr. Chapman's research in the development and application of methods for estimating parameters of geoacoustic models from experimental data has stimulated work in this research field in naval, academic and applied research laboratories nationally and internationally. He has published over 100 refereed papers on ocean acoustic propagation and geoacoustic inversion, mostly in the IEEE Journal of Oceanic Engineering and the Acoustical Society of America, and has presented over 125 papers at conferences (~30 invited). Currently he is the acknowledged leader of the ocean bottom interaction group in the US Office of Naval Research (ONR) program in shallow water acoustics.
This talk follows the development of his career in ocean acoustics from the early days in Defence Research at the laboratory in Esquimalt before coming to the School of Earth and Ocean Sciences as the Senoir Chair and Professor of Ocean Acoustics at UVic in 1995. Over this time at UVic, his research expanded to include geoacoustic characterization of marine gas hydrates, and applications of acoustic sea bed classification for marine habitat assessment in collaborative projects with the local marine R&D industry, Quester Tangent Corporation.
