easterly of SE; section G, extending northeasterly from abont 47°10' 

 X., 4S°40' W.; section F2, an east-west section between the Grand 

 Banks and Flemish Cap along the parallel of 47°15' X.; section F, 

 similar to Fo but about 30 miles farther south (normals for G and F 

 published in Bulletin X^o. 42 of this series); section T, extending 

 southeasterly from about 46°20' X\, 49°00' W.; section U, extending 

 easterly from the Grand Banks at about 45° X".; and section W. 

 extending southerly from the Grand Banks at about 50°lo' W. 

 (normals for T, U and W published in Bulletin Xo. 46 of this series). 

 Data are still insufficient for the development of even tentative 

 normals for sections H and Fo. 



During the four surveys and postseason survey of 1961, there were 

 23 occupations of these sections. From these data, the volume trans- 

 port (given in millions of cubic meters per second), mean temperature 

 and minimum observed temperature (given in degrees Centigrade), 

 and heat transport (given in millions of cubic meter degrees Centi- 

 grade per second) have been derived and their values given in Table 

 1 in comparison with seasonal normal values where these are available. 

 An examination of Table 1 shows a preponderance of subnormal 

 volume transport figures and warmer than normal mean temperatures 

 and minimum observed temperatures. Since the heat transport is 

 the product of volume transport and mean temperature, the picture 

 derived from inspection of the table is not clear-cut with respect to 

 heat transport. The volume transport at the several sections have 

 been shown in figure 20, which is a schematic representation of the 

 circulation deduced from the volume transport and mean temperatures 

 given in Table 1. 



From Table 1, it is seen that at the beginning of the season the 

 Labrador Current was subnormal in volume transport, with the ab- 

 normality greater in the southern part of the area than in the more 

 northerly part. As the season progressed, the abnormalities were 

 reduced and approximately normal conditions were reached in the 

 latter part of June. The geographical distribution of the abnormalities 

 is illustrated by considering two occupations of the Bona vista triangle 

 which averaged 103 percent of normal volume with an average mean 

 temperature 0.02° warmer than normal; the average of all sections 

 G and F was 88 percent of normal volume and 0.31° above normal 

 mean temperature; and the average of all sections T, U and W was 

 64 percent of normal volume and 0.57° above normal mean temper- 

 ature. 



From the anonuilies of volume transport and mean temperature it 

 would appear that the deficiency in the volume of the Labrador 

 Current was in its colder, inshore component. This, in combination 

 with the nearly normal conditions found at the Bonavista triangle, 

 in turn suggests that a greater than usual proportion of tlie Labrador 

 Current followed the western branch along the Avalon Peninsula of
