FY17 Annual Report on PMRF Marine Mammal Monitoring
Abstract
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. changes/cessation 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.
