3 represented 31% and 237f, respectively (stress=16.3). 

 Temperature, depth and salinity best explained the ordi- 

 n;it ion of stations, representing a cross shelf gradient from 

 nearshore high levels of salinity to increasing temperature 

 and depth offshore. Ordination of August stations (Fig. 

 8B) represented 42' i of the variance in the data, and 23% 



of the variance was loaded on axis 2 and 19% on axis 3 

 (stress=19.4). As with June, salinity increased toward the 

 coast and temperature and depth increased off the shelf. 

 The groups derived from the cluster analysis tended to 

 group together in multivariate space, with the exception 

 of group B in the June cruise (triangles in Fig. 8A).
