A high surface temperature, with 5° drop in 100 meters; 

 a low surface sahnity, rising 2 points in 100 meters. Nine 

 species only were found at the surface, 34 at 50 meters, and 

 38 at 100 meters. Twenty-seven species (52 per cent) were 

 each confined to a single tow and only 4 were present in all 

 three tows. The 100-meter tow contained the only record for 



Lucicutia grandis and the 50-meter tow one of two Atlantic 

 records for Corycaeus clausi. The small species of Corycaeus, 

 Farranula, Oithona, and Oncaea were especially abundant in 

 the two deeper tows. Again none of the 4 Oithona species, 

 only 1 of the 4 Farranula species, and 1 of the 3 Oncaea species 

 appeared at the surface.
