Abstract

Aerial surveys for marine species monitoring occurred 10 through 12 December 2013 for an AN/AQS-20 (Q-20) sonar system test event. These surveys were conducted off the west coast of Florida in the Naval Surface Warfare Center Panama City Division (NSWC PCD) Study Area in the Gulf of Mexico. The Q-20 is a high-frequency active sonar (HFAS) system used in mine detection and countermeasures.
