A numerical model and data base study was designed to install an environmental data base for the South Atlantic Ocean and for use in conducting a limited scope acoustic transmission loss and ambient noise model study. The data base framework has been installed and tested. The model study has been conducted and several tentative conclusions have been reached regarding the acoustic nature of the South Atlantic. The limited adequacy of the current data base to provide accurate predictions of the acoustic sensitivity of the region is discussed. Recommendations for data base and model improvements are provided with an eye toward modeling support of future exercise planning in the region. (Author)
