The grab was usually filled when soft fine-grained 

 bottoms were sampled. In rocky bottoms it was less suc- 

 cessful, so either a biological dredge or a trawl was 

 used to obtain qualitative measures. Volumes of indivi- 

 dual grabs varied most in shallow water where sediments 

 were hard packed. Thus, differences from nearby stations 

 varied as much as 300%o For example, in sector I W-12c 

 at station 4325 with a medium to coarse green glauconite 

 sand bottom, 1,88 cubic foot was recovered, and in 

 I W-19a at station 4329 in silt and sand, 0,06 cubic 

 foot was recovered. 



Baited lobster traps were used in the vicinity of 

 the outfall to lure foraging animals not easily taken 

 by other means. At first, traps with copper and brass 

 fittings were lowered and found unsuccessful, perhaps 

 because of repellant metallic ions leached into the 

 seawater. Another time the entrance of the trap had 

 been clogged by a crab too large to enter or escape, 

 so that the entrance of other kinds of animals was impeded, 

 Other traps recovered various foraging animals such as 

 crabs, flounders, and snails, and smaller associated 

 animals. 



Beam-trawl fishing (Zone II-5) was incidental except 

 for the catch of certain kinds of fishes from water over 

 a shallow sandy bottom. 



Some human factors are probably reflected in the 

 sorting and analyses of the samples, which were done
