3.3 KILL PROBABILITY CALCULATIONS . These were done by the 

 method presented in Reference 1. Basically, this consists of 

 calculating the damped oscillatory response (radial oscillations) 

 of a spherical air bubble corresponding to the fishes' swimbladder. 

 This oscillatory response supplies the calculated damage parameter 



Z = X + Y (3.3.1) 



where 



X = -100 In AMIN/A. (3.3.2) 



Y = 10 In AMAX/A. (3.3.3) 



Where In is the natural logarithm, A. is the initial at-rest bubble 

 radius, and AMIN and AMAX are the smallest and largest radii during 

 the oscillatory response.* Note, that we choose not to combine 

 Equations 3.3.1,2,3 into Z = 100 In AMAX/AMIN in order to emphasize 

 the fundamental independence of the damage parameter components, 

 X and Y. 



*ln this study AMAX occasionally occurred prior to AMIN, and this was permitted 

 even though this has not happened under the testing conditions studied to date, 

 (However, had we not used the occasional AMAX values occurring prior to AMIN 

 the results of this study would still he, for practical purposes, identical , )
