Vessel-based Marine Mammal Survey on the Navy Range Off Kauai in Support of Passive Acoustic Monitoring and Satellite Tagging Efforts, 1-9 February 2014

About

HDR vessel-based visual monitoring for marine mammals was conducted 1–9 February 2014 in conjunction with Cascadia Research Collective (CRC) satellite-tagging and real time acoustic monitoring by the Marine Mammal Monitoring on Navy Ranges (M3R) team. These efforts were to aid species-validation projects conducted in and around the Pacific Missile Range Facility (PMRF) instrumented range, northwest of Kauai in the Hawaii Range Complex (HRC). The monitoring survey was conducted prior to the commencement of the U.S. Navy’s Submarine Commanders Course (SCC) that took place 17–21 February 2014, which included the use of mid-frequency active sonar.
