FiGUEH 60.— Temperature at 600 meters July lO-Septeraber 11, 1928. 



Strait Ridge might be reflected later along the course in a corre- 

 spondingly warmer and saltier Labrador Current. 

 ^The p?eLnce of frigid water of -1.5° C, at a depth of 100 meters 

 over the Newfoundland shelf in September clearly emphasizes the 

 small interchange of heat of subsurface waters on journeys as great 

 as 2,000 miles in length.
