has been established and is underway through the Strategic Environmental 

 Research and Development Program (SERDP). 



Dual use of the Integrated Undersea Surveillance System provides similar 

 opportunities for the civilian community in a number of important scientific and 

 environmental applications, and we have been working with NOAA specifically 

 to demonstrate capabilities in marine mammal monitoring, marine seismology, 

 and fisheries law enforcement. 



Whales '93 : Since whales vocalize loudly and frequently, lUSS receivers can 

 detect whales every day on practically every acoustic beam in the system; 

 however, since these sounds are interfering noise sources when looking for 

 submarines it was necessary to remove them by signal processing. By treating 

 whale sounds as the signal, it is possible for the first time to develop a real- 

 time, basin-wide synoptic view of whale locations and tracks from shore 

 without disturbing the whales. 



Whales '93 is a six month test begun in November 1 992 to utilize lUSS 

 to monitor and track several species of whales in the Western North Atlantic. 

 In the first three and a half months of Whales '93 a phenomenal number of 

 discoveries have been made about deep water whales. According to the 

 civilian scientists involved, more detections of blue, finback, and minke whales 

 have been made than are contained in data bases for all previous coastal whale 

 studies. Already, more new sound types have been recorded and patterns of 

 vocalization documented than there are in all past scientific literature combined. 

 The world's knowledge of whales is being redefined.
