FiGUKE 58. — Temperature at 400 meters July 19-September 11, 1928. 



At. a depth of 100 meters water colder than —1.0° C. transported 

 by the Labrador Current was found throughout the length of the 

 American shelf except in the offing of Hudson Strait and the Strait 

 of Belle Isle. These interruptions in the otherwise uniform distribu- 

 tion of the Arctic water north of the Grand Banks indicate a dis- 

 ; iiuptive effect of the warmer discharges from both of these openings.
