The temperature was high at the surface but dropped 2° 

 at 50 meters and 9° at 100 meters; the salinity and hydrogen- 

 ion concentration were high, with httle variation at the three 

 depths. Fourteen species were found at the surface, 23 in the 



50-meter tow, and 21 in the 100-meter tow. Sixteen (47 per 

 cent) were confined to a single tow and only 6 were present in 

 all tows. The small species of Corycaeus, Farranula, and Oncaea 

 were abundant in the surface tow, but Oithona was absent.
