both surveys. The occupation of the Bonavista triangle during the 

 postseason cruise was not very satisfactory from the standpoint of 

 equating horizontal inflow past the northwest side to outflow past the 

 southwest and southeast sides. Thus the volume transport into the 

 triangle was found to be 5.15, whereas the sum of the outflow past the 

 other sides was 5.82. The volume transport anomalies were positive 

 at all three sides. The mean temperatures were above normal at the 

 two sides where the greatest transports exist and below normal along 

 the southwest side. The resulting heat transport was hence correspond- 

 ingly greater than normal with the above mentioned discrepancy of 

 inflow and outflow being repeated and giving the inflowing heat at 

 10.23 and the outflowing heat at 12.84 for an average positive anomaly 

 of 4.86. The minimum observed temperatures were near normal at the 

 northwest and southwest sides and about a quarter of a degree above 

 normal at the southeast side. 



Farther north, off South Wolf Island, Labrador, the volume transport 

 of the Labrador Current was found to be 10.22 which is some two times 

 the average value for the 20 occupations of this section. The mean 

 temperature was about a half degree warmer than average and the 

 minimum observed temperature of —1.70 was near the coldest recorded 

 for the 20 occupations (-1.72 in 1940 and -1.70 in 1949) and 0.2° 

 colder than average. Because of the large volume transport and high 

 mean temperature the positive anomaly of heat transport was very 

 large. As the South Wolf Island section was occupied only a few days 

 after the occupation of the Bonavista triangle and the volume transport 

 found was about twice that past the Bonavista triangle a volume trans- 

 port of 4.7 has been indicated in figure 24 as moving off to the eastward 

 between the South Wolf Island section and Bonavista. 2 



At the Greenland end of the section across the Labrador Sea the West 

 Greenland Current off Cape Farewell was also found to be unusually 

 vigorous with a volume transport of 9.74 which is more than twice its 

 seasonal normal of 4.41. Although the mean temperature of 4.15 was 

 about three quarters of a degree below the seasonal normal of 4.89 the 

 resulting heat transport of 40.39 was very large compared to its normal 

 value of 21.56. If the mean temperatures of the East Greenland Current 

 and Irminger Current components of the West Greenland Current are 

 taken as constant at 3.2 and 5.5 respectively the computed volume 

 transports of the components may be derived as 5.73 for the East Green- 

 land Current component for a positive anomaly of 4.56 and 4.01 for the 

 Irminger Current component for a positive anomaly of 0.77. As the 

 mean temperatures have been assumed constant the anomalies of heat 

 transport are proportional to those of volume transport and are com- 

 puted as 14.60 and 4.23 respectively.
