The Navys interest in the lower region of the acoustic frequency domain has increased the need for more definitive models of the oceans subbottom as a transmission media that refracts, diffracts, diffuses and dissipates, as well as reflects, acoustic energy. A multi-channel array system towed near the bottom in the deep ocean provides the capability to determine the detailed geophysical character of the subbottom structure and thus provides the high resolution geoacoustic input parameters required for modeling. This report presents the progress during FY78 on the development of a deep-towed system. The report reviews progress on the development of a system performance prediction model, interval velocity measurement considerations, and deep tow sound source requirements. Author
