92 INTERNATIONAL ICE OBSERVATION AND ICE PATROL SERVICE. 

 PROFILE NO. 14. STATIONS 239 TO 243. 



This section runs from station "('" (see Chart "A") southwesterly 

 into dee]) water. It was occupied June 16 to 17, and is the last of the 

 oceanographic station observations for 1922. 



Salinity. — Atlantic water >35.0 "/oo is present at the outer end of 

 the section in large volume. Bank water < 33.0 "/oo spreads unusually 

 far southward from the bank in a thin surface la3"er to station 241. 

 In over the bank we find 32.30 7oo to 32.96 "/qo water, which is slightly 

 Salter on the bottom than two weeks earlier. 



Temperature. — Warm water > 10° C. occupies station 242 down to 

 300 meters, and extends northward on tlie surface to station 241. 

 Solar warming of the surface layers is noticeable; for example, the 

 bank station, 239, registers 6.7° C, where in March it was 0.2° C. 

 A minimum of 3.2° C. below the surface at the slope station, 240, 

 might suggest the Labrador Current, and although this temperature 

 is too high for the latter unadulterated, the negative temperatures 

 on the bottom of the bank point to a drainage of polar water down the 

 slope as the cause of the subsurface minimum at station 240, for the 

 source of tlie icy water on the banks is undoubtedly the Labrador 

 Current which has si)read in over the bottom from the northeast. 



Comparing profile No. 14 with i)rofiles Nos. 7 and 10, in the same 

 locality, we may state developments as follows: On April 25 there 

 was a well-defined Labrador Current bathing the southwest slope of 

 the bank. This had ceased to flow by May 23, but the effects of its 

 low tem])erature remained on the slope where it had been observed 

 in great volume a month earlier. 



Since Arctic water brought to the slope of the bank at this place in 

 April has been engulfed by warm, salty water working northward 

 toward the slope, it is fair to assume that the icy cold layer on the 

 bank would have been warmed had it not a source of constant supply, 

 this necessarily being the Labrador Current to the north and east.
