The high surface temperature dropped almost SO per cent 

 at a depth of 100 meters, but the salinity remained practically 

 the same and the hydrogen-ion concentration dropped 0.4 

 of a point. Sixteen species were found at the surface and 19 



at the 100-meter level, and only 4 species were present in both 

 tows. The 100-meter tow contains the second Atlantic record 

 of Microcalanus pygmaeus, the two thus occurring at adjacent 

 stations. 



Station 26

Towing was done at the surface onl\-, with temperature omitted. This is a smaller record than that for station 10, 



27?6, salinity 36 o/oo, and hydrogen-ion concentration 8.30. but this is one tow only, taken under very adverse conditions, 



Owing to very bad conditions, hea\y tide rips, strong cross- whereas at station 10 all three tows were taken under good 



currents, and a rolling sea, the two deeper tows had to be conditions.
