REPRESENTATIVE DIGITAL PRINTOUTS FROM 



SPECTRUM ANALYSES PERFORMED BY 



THE NOSC IDHACS FACILITY 



The following materials are copies of the digital printouts from the NOSC 

 IDHACS (Intelligent Data Handling and Control System). These data are 

 presented as representative examples of the hardcopy obtained from IDHACS on 

 each analysis performed. The example presented here is for a measurement 

 position approximating 50 feet from the bow structure of Ocean Bounty and 

 hydrophone depth of 50 feet. Two analyses are presented, each preceded by an 

 IDHACS status sheet. The first analysis is for 16 Hz analysis bandwidth on 

 the AM recording; the second, for 0.8 Hz analysis of the FM recording. 

 Graphic presentations of these same data are shown in Figures 1 and 2 of the 

 report.
