STATION 431 



This station was taken on the northwestern part of the Grand 

 Banks, near the edge of the " gulley," May 2, and it is of interest

The temperatures ranged from 2.5° on the surface to 0.2° on the

 Voo near the bottom. Compared with the record taken there in April 

 we found that cooler and considerablv Salter water had been en-
