points near the end portions of the curves are a common feature. 

 The lower left inversion with an approximate value of temperature 

 of —1.75° C, and 33.14%o salinity, represents typical Arctic water, 

 and the upper right inversion is representative of west Greenland 

 water. Along the straighter part of the curves fall the correlation 

 points indicative of the Labrador Current.

ANNUAL VARIATIONS 



The question whether or not the oceanographic conditions in the 

 American sector already described in this chapter as existing in 

 1928 prevail during most summers can best be answered by the 

 U. S. Coast Guard's surveys made there in 1931, 1933, and 1934. , 



In can be seen by comparing figures 67, 68, and 69 with figure 47 

 that the surface extent of the Labrador Current remains fairly con- • 

 stant summer to summer. The previously described sinuous form
