the central tendency of the directional spread parameter appears to be about 

 the same for all energy levels. Though there are not many high-energy cases, 

 the few existing points are scattered, rather narrowly, about a spread of 

 40 deg. The same clustering is seen at the lowest energies. 



197. This behavior is also seen in the correlation of A^j^g with 



Tp jFs (Figure 20). Excepting a few outliers, directional spread characteris- 

 tics appear to be roughly the same for all values of peak period. The large 

 spreads at low Tp jpg are likely the result of waves from light, irregular 

 winds and coexisting swell. These correspond to the large spreads at low 

 energy shown in Figure 19 . 



198. The same tendency is shown in Figure 21 where directional spread 

 is correlated with peak direction ^p.ios • Though the overall scatter in 

 spread values is slightly lower for shore-normal peak directions (0 deg) , the 

 most common spread tends to be around 40 deg for all peak directions. 



199. Figure 22 shows directional spread correlated with bulk steepness. 

 Here, again, the characteristic directional spread appears relatively
