REAL-TIME PROCESSING OF ACOUSTIC AND OCEANOGRAPHIC DATA AT SEA.
Abstract
A data acquisition and analysis system was developed and installed aboard the oceanographic research vessel USNS SANDS 9AGOR-6) to provide a capability for comprehensive data analysis at sea, including the ability to perform data processing in real time. The system is built around the UNIVAC 1230 computer. Peripheral equipment permits up to 64 channels of data to be fed to the computer through a 50-kHz A/D multiverter. The processed output is displayed on a high-speed on-line printer-plotter. Four tape decks for data storage and read-out permit continuous operation with no off-line time required for changing tape or data read-out. The system was used extensively during a 3-1/2 month cruise devoted to oceanographic and acoustic studies on a track from New London, Connecticut, to Hawaii and return. The processing system was also required to be on line continuously for a three-week period for acoustic propagation studies conducted in the North Pacific. These tests proved highly successful and demonstrated the desirability of at-sea data processing by permitting scientists aboard ship the opportunity to collect, process, and evaluate results during the course of the experimental exercise.
