Abstract
Three aerial marine-species monitoring surveys for an AN/AQS-20 sonar research, development, test, and evaluation (RDT&E) event occurred, with daily marine-species surveys from 05 July through 09 July 2011, 23 July through 26 July 2011, and 20 May through 26 May 2011 off the coast of Florida in the Naval Surface Warfare Center Panama City Division (NSWC PCD) Study Area in the Gulf of Mexico (GOM). The AN/AQS-20 is a high-frequency active sonar (HFAS) system used in mine countermeasures detection.
