Forty-four species were present at the surface, 37 in the 50- 

 meter tow, and 49 in the 100-meter tow. The surface tow of 

 0.5 mile yielded more than six times the volume of plankton 

 that was obtained in the 100-nieter tow of 0.8 mile, but the 



latter contained 5 more copepod species than the former. 

 The three tows totaled 75 species, of which 38 (51 per cent) 

 were each confined to a single depth, and 15 were found at all 

 three depths.
