Advanced Wide Aperture Cluster for Surveillance (AWACS)

Abstract

This project involved making concurrent acoustic propagation & physical oceanographic measurements to determine environmental factors affecting low-frequency acoustic propagation in the shelfbreak front in the Middle Atlantic Bight. Autonomous Underwater Vehicles (AUVs) were used within the front to determine frontal structure as well as the impact of sound speed variability within the front on transmission loss. Successful AUV operations were conducted in three separate cruises. A list of environmental keys were determined which were simple means of determining the impact of shelfbreak frontal structure on acoustic propagation through adaptive sampling via mobile acoustic sources and sonobuoys.
