The use of navy range bottom-mounted, bi-directional transducers for long-term, deep-ocean prey mapping
Abstract
In response to mid-frequency active sonar (MFAS), beaked whales appear to move from an area and return once the disturbance has diminished. It is presumed these animals occupy areas of high prey concentration, but the relative distribution of prey at depths below 1,000m is little understood. This project will evaluate using existing bottom-mounted transducers for mapping of relative prey availability over broad spatial and temporal scales by leveraging bidirectional nodes found on the Navy s undersea acoustic ranges including the Southern California Offshore Range (SCORE), the Atlantic Undersea Test and Evaluation Center (AUTEC), and the Pacific Missile Range Facility (PMRF).
