As used here, "relative" indicates the spectra have been smoothed by the 

 three-dimensional surface drawing routine. Consequently, extremely high- 

 and low-energy density values are modified to produce a smooth surface. The 

 figures are not intended for quantitative measurements; however, they do pro- 

 vide the energy density as a function of frequency relative to the other spectra 

 for the month. 



Monthly and annual wave statistics for Gauge 630 for 1994 and for 1980 

 through 1994 are presented in Table B7. 



Figure B9 plots monthly time histories of wave height and period.
