Sightings for Airborne Mine Neutralization System Vessel Monitoring in the NSWC PCD Study Area from December 2011

The U.S. Navy Marine Species Monitoring Program

Vessel-based marine species monitoring occurred during 5 through 10 December 2011 for an
Airborne Mine Neutralization System (AMNS) live-inert explosives research, development, test,
and evaluation (RDT&E) 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 (GOM). The AMNS is a mine countermeasures device that includes an explosive
charge.
