The U. S. Naval Oceanographic Office (NAVOCEANO) received an urgent requirement in November of 1966 to conduct reconnaissance hydrographic surveys of the rivers and canals in the Mekong Delta of South Vietnam. A prototype hydrographic digital positioning and depth recording system (HYDRA Survey System), compatible with existing electronic positioning systems and capable of data acquisition at speeds in excess of 20 knots, has been developed by the Research and Development Department of the U. S. Naval Oceanographic Office. This system is especially designed for military survey area applications. Results of experimental test surveys conducted with the prototype HYDRA Survey System (HYDRA I) at AUTEC Site 1 in the Bahamas, and the modified HYDRA Survey System (HYDRA II) near Ft. Walton Beach, Florida, are highlighted with special emphasis given to future applications.
