Biography

Jaroslaw J. Tegowski received the M.Sc. degree in physics from the University of Gdansk, Poland, in 1981 and Ph.D. degree in physical oceanography from Institute of the Oceanology, Polish Academy of Sciences, in 1995. Since 1983 he has been a Scientist at the Institute of the Oceanology, Polish Academy of Sciences. His research interests include the acoustical investigations of the sea bottom properties, signal processing, numerical modeling of sound scattering on rough surfaces, plankton and fish detection, research of sound generation by breaking waves. After receiving the Ph.D. degree he continuing his research as a Post - Doctoral Fellow at the Scripps Institution of Oceanography, University of California, San Diego on the problem of the effects of intermittent of air bubbles by breaking wind waves on ocean reflectance and underwater light field. He is now in charge of a research program on acoustical investigations of the gas bubble concentrations with nonlinear methods, his current interests being both in physics of seabed backscattering and in sonar signal processing.
