SUMj\rARY 



A wide band of low-salinity water associated with a coastal con- 

 nection lay in the surface layers south of Cape Race, June 25. whil.' 

 in the lower depths frigid Arctic water bathed the " gulley " and 

 crept southward as a thin film over the bottom of the Grand l^ank 

 100 miles offshore from Cape Race. East, oil Cape Race, the Arctic 

 water flooded all depths, surface to bottom, but as we proceeds 

 toward the liank the Arctic influence grew less and less, until at the 

 outer station, 479, it was confined solely to the bottom 25 meters ( 1 1 

 fathoms). On the other hand the influence of the fresh coast;! 

 water in the surface la3'ers became increasingly effective, reaching 

 a maxMuuiii in the midseason.
