Coastal Acoustic Tomography begins with the specifics required for designing a Coastal Acoustic Tomography (CAT) experiment and operating the CAT system in coastal seas. Following sections discuss the procedure for data analyses and various application examples of CAT to coastal/shallow seas (obtained in various locations). These sections are broken down into four kinds of methods: horizontal-slice inversion, vertical-slice inversion, modal expansion method and data assimilation. This book emphasizes how dynamic phenomena occurring in coastal/shallow seas can be analyzed using the standard method of inversion and data assimilation. The book is relevant for physical oceanographers, ocean environmentalists and ocean dynamists, focusing on the event being observed rather than the intrinsic details of observational processes. Application examples of successful dynamic phenomena measured by coastal acoustic tomography are also included. - Provides the information needed for researchers and graduate students in physical oceanography, ocean-fluid dynamics and ocean environments to apply Ocean Acoustic Tomography (OAT) to their own fields - Presents the benefits of using acoustic tomography, including less disturbance to aquatic environments vs. other monitoring methods - Includes the assimilation of CAT data into a coastal sea circulation model, a powerful tool to predict coastal-sea environmental changes

Professor Kaneko started his academic career as a research associate in Kyushu University. In 1980, during his time as a research associate in the Research Institute for Applied Mechanics (RIAM), Kyushu University, he was awarded Doctor of Engineering. In 1981, he was promoted as an associate professor in RIAM. After that, he shifted research field from the nearshore fluid dynamics to open-ocean fluid dynamics and started a challenging structural observation of ocean currents such as the Kuroshio Current and Tsushima Warm Current, using a newly-developed towed-type acoustic Doppler current profiler (ADCP). From 1985 to 1986, Professor Kaneko worked at Woods Hole Oceanographic Institution, extending his research to ocean acoustic tomography (OAT). In 1991, he moved to the Graduate School of Engineering, Hiroshima University, as a full professor. At this time Kaneko set up a lab studying OAT and began exploring the now well-established technology and method of applying OAT to coastal sea study, with more acoustic complexity. The coastal acoustic tomography (CAT) group, which was established in Hiroshima University and composed of research staff and graduate students educated in Kaneko's laboratory, have visualized (mapped) variable coastal currents with methods combined by inversion and data assimilation in the last two decades and results have been released to the international oceanographic community
