Description
Summary:Volume reverberation resulting from the deep scattering layers (DSL) is an important source of interference to acoustic systems in large areas of the world's oceans. Much is unknown about how volume reverberation varies, diurnally, seasonally, and geographically. Since it is a biological phenomenon that manifests itself acoustically, a multidiscipline approach is required in its investigation. Navy laboratories, their contractors, private industry, and academic and research institutions are engaged in basic and applied research involving the acoustic and biological characteristics of the DSL. In many investigations, sampling at sea has been conducted by either acousticians or biologists generally as independent operations, whereas a joint program would serve both fields to greater advantage. Furthermore, many studies of the DSL have not been adequately coordinated; that is, data have been obtained without any long-term goal in mind or, even more importantly, without standardized sampling methods and equipment. Experience has shown that the more fruitful studies of the DSL have been coordinated efforts between acousticians and oceanographers. Hence, the Navy Underwater Sound Laboratory initiated the Ocean Acre program in order to investigate the DSL from various aspects and viewpoints, employing expertise from many areas of acoustics and biology with the prime goal of understanding the biology, ecology, and acoustics of the DSL and how these factors relate to the needs of the Navy.
