In United States Coast Guard Bulletin No. 26 the seasonal variation 

 in the Labrador Current in the Grand Banks sector was discussed 

 and evidence presented tending to show that there was a seasonal 

 maximum volume of flow occurring during the month of May. 

 Measurements made during 1937 confirmed this. The sections 

 involved are as follows: Section T, running southeasterly from about 

 latitude 46°20' N., longitude 49°00' W.; section U, running east and 

 west at about 45° N.; and section W, running south off the Grand 

 Banks in about 50° W. Section T was reoccupied May 1, June 1-2, 

 and June 30; section U was reoccupied April 10, May 3, June 4, and 

 June 29; and section W was reoccupied April 3-4, May 7-8, and June 

 21-22. The volume of flow, mean temperature, and minimum observed

temperature was investigated for each occupation of these sections 

 and the results are tabulated below along with similar results for all 

 occupations of these sections during 1934, 1935, and 1936. 



In figure 37 is shown grapliically the seasonal variation in the 

 volume of flow of the Labrador Current past sections T, U, and W 

 during the 1937 season. 



There is some evidence that the unusual activity of the West 

 Greenland Current rounding Cape Farewell in 1935 was still making 

 its effect on the Labrador Current felt. The immediate effect of this 

 1935 flood seems to have been the sweeping of the American side 

 clean of bergs with the result that a greater than expected number of 

 bergs arrived in the Banks region that year. The next effect was the 

 warming of the offshore part of the Labrador Current through the
