Presentation title: “The Application of Bayesian Methods in Ocean Acoustics and Geophysics”
Presenter: Prof. Stan Dosso
Time: 10:00 am, April 16, 2018
Location: Academic lecture hall on the 15th floor of the Underwater Acoustic Engineering Building
Short Bio of the presenter:
Stan Dosso received BSc and MSc degrees in Physics and Applied Mathematics from the University of Victoria and a PhD in Geophysics from the University of British Columbia (all in Canada) He worked as a Defense Scientist in Arctic Ocean Physics at the Defense Research Establishment Pacific in Victoria before taking up an Ocean Acoustics Research Chair in the School of Earth and Ocean Sciences at the University of Victoria, where he is currently a Professor and Director of the School.
Stan is a Fellow of the Acoustical Society of America (ASA) and a member of the American Geophysical Union and the Canadian Acoustical Association, which he served as President from 2003-2007. He was awarded the ASA Medwin Prize in Acoustical Oceanography and the Science Teaching Excellence Award by the University of Victoria. He has authored/coauthored more than 150 papers in peer-reviewed journals.
His research interests centre on the remote sensing of seabed geoacoustic properties and processes via the inversion of marine acoustic data. Related research interests include inverse problems in earthquake seismology, ocean acoustic localization and tracking, and marine-mammal acoustics. His focus in all areas is in the development and application of Bayesian (probabilistic) inversion methods which provide quantitative uncertainty analysis that yield insight into the properties/processes under investigation.
Abstract of the presentation:
This talk presents an overview of Bayesian (probabilistic) inversion methods used in ocean acoustics and geophysics. A series of illustrative examples include: (1) Trans-dimensional inversion of acoustic reflectivity data for seabed geoacoustic profiles; (2) Bowhead whale acoustic localization and environmental inversion via warping time-frequency analysis of modal dispersion; (3) Ambient seismic-noise inversion for earthquake hazard site assessment.
