The temperature, salinity, and hydrogen-ion concentration 

 were high and did not change in the 50 meters. Twenty-three 

 species appeared at the surface and 39 in the 50-meter tow. 

 Thirty-two species (70 per cent) each were present in one tow 

 and not in the other, and 15 were found in both tows. Again 

 the Eucalanus species, EiicliireUa. Ilelerorhahdus, Luhhnckia, 



Megacalanus, and Rhincalanus were confined to the deeper 

 tow, and Corycaeus, Farranula, Oithona, and Oncaea were 

 well divided between the two tows. One species of Candacia 

 was abundant in both tows; the other 3 species did not appear 

 at all at the surface. Clausocalanus was found only at the 

 surface.
