Figure 6-10 Distribution of spectral parameters versus azimuth for con- 

 tinental rise bathymetry shown In Figures 6-8 and 6-9. 

 Spectral slope (above) shows no apparent functional rela- 

 tionship to azimuth and has a mean slope of -1.05. The 

 intercept parameter (below) reflects the relatively smooth. 

 Isotropic nature of the surface. Model parameters are as 

 follows: mean amplitude = 0.097 m, amplitude of sinusoid = 

 0.0063 m, azimuth of maximum energy * 120°. Due to the low 

 level of anisotropy, the azimuth direction Is not signif- 

 icant.
