This report summarizes the findings of an Oceanographic Data Bank Survey. The survey was conducted in order to eliminate duplication of data base development and to aid the Data Base Manager in establishing the data banks for the Acoustic Environmental Support Detachment AESD. A key finding is that no one data bank exists that will satisfy the total needs of AESD. Data bases available from the National Oceanographic Data Center NODC, Fleet Numerical Neather Central FNWC and the U. S. Naval Oceanographic Office NAVOCEANO will be required to construct the initial AESD environmental data banks. None of the agencies surveyed has achieved an interactive graphics capability that approaches the state of development that AESD will probably require. Some sources of data AESD might use to construct its environmental data banks are presented, and the advantages and disadvantages of each source are discussed. Methods of structuring the AESD environmental data banks for both near term and longer range use are discussed.
