shown by its extreme coldness, especially below the surface (0° to 

 — 1.9°). Such temperatures never could be produced locally during 

 the ice season and are comparable only with those of the discharge 

 from the far north, the salinity of which corresponds to that found 

 along the continental edge of the Grand Bank. Such water, there- 

 fore, must have been transported to the Grand Banks region from 

 elsewhere. 



There is a cold, icy current flowing clockwise around the Atlantic 

 faces of the Grand Bank, more clearly defined along the east side 

 and around the Tail than elsewhere, which we call an extension of 



the Labrador Current in the absence of a better name. But it does 

 not follow a continuous stream flow (riverlike) from its source, the 

 Arctic, to the Tail of the Bank at all times throughout the year. 

 In summer, when this current becomes weak, the continental edge 

 fi'om the Labrador coast to the 43d parallel is the seat of regional 

 icircuits of circulation. The well-known augmentation occurring in 

 the northern current every spring results in a more continuous 

 flow made visible by the transference of Arctic freight in the form of 

 icebergs. 



It is well established that the water masses from the north flood 

 the northern part of the Grand Bank, where the current forms two
