Figure 4-4 Spectral estimates collected by T. H. Bell (1975b) from 

 various sources. The linear distribution of the data 

 illustrates the power law form of submarine topography 

 spectra for a wide range of scales. Notice that this spec- 

 trum is plotted versus power (amplitude squared) which 

 results in a doubling of the ordinate and the slope of an 

 amplitude spectrum. Refer to Bell (1975b) for data 

 sources.
