The temperature was high at the surface and fell 6?3 in 

 the 100 meters; the salinity diminished and the hydrogen-ion 

 concentration increased slightly. Ten species were taken at 

 the surface, 23 in the 50-meter tow, and 25 in the 100-meter 

 tow. Twenty-eight species (70 per cent) were each confined 

 to a single tow and 4 were present in all three tows. The two 



deeper tows were a little more than twice the length of the 

 surface tow and their volume was twice as large. Corycaeus 

 did not appear in the 100-meter tow, Farranula was confined 

 to the surface tow, Oithona was found only in the 100-meter 

 tow, and Candacia and Oncaea were distributed at all three 

 depths.
