Abstract
The solution of acoustic wave propagation in the ocean is a well established component in the toolset for the detection and identification of underwater sound sources. However, in order to carry out such computations, detailed information is required on ocean bathymetry as well as a variety of acoustic properites of the ocean and of the sediments under the ocean bottom. In this report, we describe a prototype Environmental Database (EDB) that has been built to provide this information. Designed around a Relational Database Management System (RDBMS), this EDB is shown to be faster and more efficient than one based on a flat file system. The report concludes with some recommendations for the next phase of the EDB development.
