Fig. 16. Areal distribution of "index groups" of assemblages in the northern nearshore shelf 

 environment. Station composition and range of ecological factors for each group can be found 

 in Table III. The boundaries of the groups are somewhat subjective, agreeing in general with 

 the bathymetry and sedimentary patterns. Station numbers shown are those with highest 

 affinity, although others were involved in determining the boundaries, but were much less 



important. 



common species were found, and also those species which were either 

 unique to or had the greatest percentage of occurrence within these sta- 

 tions. A map of the station locations resulting from this analysis is shown 

 on fig. 17.
