Figure 6-12 Distribution of spectral parameters versus azimuth for con- 

 tinental slope/submarine canyon bathymetry shown in Figure 

 6-11. Spectral slope (above) has a mean value of -1.88, 

 although it maiy also contain a cyclical component not noted 

 in other examples. The intercept parameters (below) repre- 

 sent an intermediate level of both mean roughness and 

 anisotropy between those of the Gorda Rise and Continental 

 Rise examples. Model parameters are as follows: mean 

 amplitude = 0.87 m, amplitude of sinusoid - 0.23 m, azimuth 

 of maximum energy = 85*. Due to the direction of sampling, 

 true azimuth on the earth corresponds to 45°.
