Figure B-2 An example of uniformly distributed random noise Is shown 1n 

 upper profile. Its corresponding amplitude spectrum (1n 

 lower profile) shows the flat (zero slope) form Indicative 

 of white noise. Notice the high degree of scatter In ampli- 

 tude estimates. The same computer software was used as that 

 used for bathymetric data.
