SACLANTCEN sponsored an environmental acoustic measurement in the Ligurian Sea in August 1999. The objectives of this cruise were to detect, localize and track marine mammals using passive acoustic techniques. During this cruise, the R.V. Alliance passively operated several advanced sonar arrays near Corsica. Acoustic techniques were used to localize and track several species of cetaceans in position and depth over time from their vocalizations only. The acoustic results are compared to ground truth provided by visual observations and data from several radio tags with time‐depth recorders. Statistics on whale vocalizations and behavior are tabulated. At the time of this abstract submission, it is anticipated that data on Fin, Sperm and other cetaceans will be available. |
