Not Available Navy Submarine Towed Acoustical Array Systems are experiencing loss and damage due to attacks from marine life such as sharks and other fish. During the period of 1993 to1995, over 20 TB-16 Kings Bay Georgia based arrays were replaced due to suspected marine life attack, costing millions of dollars. Research into the cause of these attacks is needed, along with solutions and/or countermeasures the can be implemented without reducing performance. Texas Research Institute Austin, Inc. will team with Dr. Philip Motta of the University of South Florida and Dr. Timothy Tricas of the Florida Institute of Technology to investigate this problem. Information acquired from NAVSEA will be used to determine possible features of the array that attract fishbite. Array segment test articles will be prepared and exposed to sharks during static and towed tests. An underwater projector will be used to introduce acoustic signals to the sharks and their response observed. Attraction by odor will be investigated using static test articles fabricated from array materials. Damaged test articles will be analyzed to identify the responsible marine species. A Phase II test plan will be prepared that includes attractant masking and active deterrents during actual towed array field tests.
