tively high in group-2 and group-4 stations and low 

 in group- 1 and group-3 stations (Table 3). 



Station groups showed little correspondence with 

 the environmental variables examined. Distance 

 from shore was the only variable that showed a clear 

 relationship to the station groups (Table 4). Group 3 

 (offshore) and group 4 (inshore) were clearly differ- 

 entiated from the remaining two midshelf groups. 

 Although group 4 was the closest to shore, it also 

 showed the greatest average bottom depth. Group 2 



exhibited the shallowest mean depth and warmest 

 mean surface temperature of the four station group- 

 ings (Table 4). Among the six variables examined, 

 only distance from shore (P<0.001) and water tem- 

 perature at 50 m depth (P=0.048) showed significant 

 differences among the four groupings. In addition, 

 the group closest to shore (group 4) had the warmest 

 temperatures at 50 m ( 3c=7.1°C) and the one farthest 

 from shore (Group 3) was colder ( x=6.4°C) at 50 m 

 than the intermediate groupings (Fig. 11).
