Abstract:

Deep ocean moored thermistor string buoys were constructed to obtain vertical temperature profiles at depths down to 1500 meters. A requirement for data acquisition in near real time was met by means of on-board signal conditioning and prompt radio transmission to a computer equipped shore station for automatic processing and subsequent use in relating acoustic propagation to temporal variations along designated acoustic paths. Two such buoy systems were launched. One was successfully implanted in about 4800 meters of water providing some 1000 hours of real time on-station temperature, environmental and housekeeping data while the second was lost during the final stage of deployment. A complete description of the equipment along with design considerations and techniques utilized is appended. Author
