The temperature was high and e.xactly the same at both 

 depths; the salinity and h5drogen-ion concentration increased 

 slightly at the lower depth. Twenty-three species were found 

 at the surface and 41 in the 50-meter tow. Thirty-four species 

 (70 per cent) were found in one tow and not in the other, and 



15 were common to both tows. Corycaeus, Farranula, and 

 Oncaea were more abundant at the surface, but 3 of the 4 

 Oithona species did not appear at all in the surface tow. The 

 2 Euchaeta species were recorded as constituting 75 per cent 

 of the 50-meter tow.
