Abstract:

Beginning in 2003 SAIC formerly AETC developed the Marine Towed Array for underwater geophysical investigations. The underwater towed platform is a 5 meter wide array containing 8 Cesium vapor magnetomers. It is towed by a 60 foot cable by a pontoon boat. The attitude and depth of the sensor platform is controlled by an autopilot. The inputs to the autopilot include a tactical grade IMU, depth sensors and digital magnetic compasses, and a dual GPS system based upon the tow vessel. The survey products include digitally geo-referenced magnetic anomaly maps of metallic objects buried in the sediment and spreadsheet tables reporting the results of analyses of individual anomalies. The system has been used to conduct six extensive underwater surveys. In this report we discuss the actual site conditions, how they affected the system operation, and how the system was adapted during the demonstrations in response to new environmental challenges that were encountered.
