In fiscal year FY 2017 the SSC Pacific Detection, Classification, Localization, Tracking, and Density Estimate DCLTDE Laboratory San Diego, California utilized passive acoustic data recordings from bottom mounted range hydrophones at the Pacific Missile Range Facility PMRF to monitor for vocalizing marine mammals both during baseline periods and during U.S. Navy training activities.The overall goals of this ongoing effort are to 1 Collect raw acoustic data for detailed verification of automated processing results and to allow future processing with new marine mammal species detection, classification and localization algorithms 2 Understand occurrence and abundance for multiple marine mammal species 3 Estimate sound levels that marine mammals were exposed to during Navy training with hull mounted mid-frequency active sonar MFAS 4 Investigate behavioral responses to Navy training activities e.g. changescessation in calling, changes to animal kinematics, and overall changes in abundance and 5 Collaborate with researchers conducting other monitoring efforts e.g., tagging and visual surveys, along with other U.S. Navy laboratories, to fill data gaps and provide a more complete monitoring data product.
