Operational Processing of Hydroacoustics at the Prototype International Data Center

The Portotype International Data Center(PIDC) has designed and implemented a system to process data from the International Mjonitoring Systemʹs hydroacoustic netwrok. The automatic systm detects and measures various signal characteristics that are hten used to classify the signal into one of three categories. The detected signals are combined with the seismic and infrasonic detections to automatically form event hypotheses the automatic results are reviewed by guman analysts to from the Reviewed Event Bulletin(REB). Continuous processing of hydroacoustic data has been in place since May 1997 and during that time a large database of hydroacoustic signals has been accumulated.
