Marine Mammal Monitoring on Navy Ranges (M3R): An Opportunistic Study of the Effect of Sonar on Marine Mammals on the Pacific Missile Range Facility (PMRF): FY14 Summary

About

With funding from the Living Marine Resources (LMR) Program, the Marine Mammal Monitoring on Navy Ranges (M3R) passive acoustic monitoring system has been installed at the Pacific Missile Range Facility (PMRF). The overall goal of the program is to provide tools and methodologies for long-term monitoring of marine mammal populations. The program is laying the groundwork needed to adapt combined passive acoustic, tagging, and visual monitoring methods for animals and conditions at PMRF. For sonar-sensitive Blainville’s beaked whales (Mesoplodon densirostris; Md), the short- and long-term distribution, density, and habitat can be measured provided basic behavioral data such as group size and dive rates at PMRF are known.
