September. Seasonal increases were smallest at JC as reflected by the very 

 gradual slope of the species curve. 



The cumulative curves over the last several years at both GN and IN 

 were generally parallel and the relationship among annual totals over the 

 last four years was identical to the relationship among the September 

 collections. In contrast, curves generated for EF and JC bisected one 

 another and despite the often large disparity in the numbers of species 

 collected in September, the annual totals were generally quite similar. 

 The JC curve for 1983 was an exception to this pattern and the absence of a 

 large June species complement (as observed in the previous year) resulted 

 in a relatively low 1983 total. 



Cluster Analysis 



The cluster analysis of subtidal community data from 1980-1983 

 produced four groups (I-IV) , each containing all years from a particular 

 station (Fig. 15). Group T contained IN sampling years, and because of low
