E. Longitudinal Relative Flow Velocity Spectra 



Figures 18 through 21 present energy spectra of longitudinal relative flow velocity 

 for Runs 3 to 6, respectively. Each figure, except Figure 20, contains four spectra 

 corresponding to a different relative heading. 



Relative headings for the first two recordings in Figure 18 are designated with 

 respect to sea because these relative headings associated with sea waves had values 

 that could result in larger longitudinal flow components, even though swell was greater 

 in height and period bandwidth (Table 1). In the last two recordings, relative headings 

 with respect to swell are considered most important, although the choice is arbitrary. 

 The extreme peak in Run 3-1, however, probably was caused by the joint contribution 

 of both sea and swell. 



In Run 3-4, both sea and swell components were from abeam of the submarine, 

 and this results in the lowest spectral values throughout the run because the longitudinal 

 component is smallest.
