A GPS enabled, low impact, minimally percutaneous electronic transmitter LIMPET tag for the in-situ study of cetaceans was developed. The tag is dart attached to individual animals at-sea using a neumatic rifle. The tag provides GPS and dive data in real-time via the Argos satellite system. The tag was successfully developed and deployed on a number of species including Cuviers beaked whales Ziphius cavirostris on the Southern California Offshore Range SCORE. A generic sonar detector was also developed and tested in-situ at SCORE with mid-frequency active sonar. The detector was integrated into the Marine Mammal Monitoring on Navy Ranges M3R signal processor and is capable of monitoring over 200 hydrophones in real-time. It is currently being used on the three major Navy ranges including the Atlantic Undersea Test and Evaluation Center AUTEC in the Bahamas, SCORE, and the Pacific Missile Range Facility PMRF in Hawaii.
