Frequency of occurrence was low with only 1 % of the 

 samples in each of the three sediment types containing 

 specimens (Table 20). 



Relation to Water Temperature 



Cephalopods were found only where the annual range 

 in temperature was less than 12°C. Density showed a 

 positive correlation with increasing temperature range 

 from <0.1 individuals/ m 2 in the narrowest (0-3. 9°C) 



range to 1.1 individuals/m 2 in the broadest (8-11.9°C) 

 range in which they occurred (Table 21; Fig. 133). 



Biomass was stable (0.02 g/ur) in the ranges be- 

 tween 4° and 11.9°C, and low (<0.01 g/m 2 ) in the 

 narrowest range (Table 23; Fig. 133). 



Less than 1% of the samples in the 0-3.9° and 8- 

 1 1 ,9°C range groupings contained cephalopods, whereas 

 2% of the samples in the 4— 7.9°C grouping yielded 

 specimens (Table 25).
