above normal for all sections. 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. 



SUMMARY 



1. Five dynamic topographic charts resulting from the four surveys 

 made in the Grand Banks region during the season and the post- 

 season occupation of the Bonavista triangle have been presented. 



2. The temperature-salinity relationships in the different water 

 masses found in the Grand Banks region in 1963 have been discussed 

 and compared with the average relationships for the 16-year period 

 1948-63. 



3. The volume and heat transports and mean and minimum ob- 

 served temperatures found during the reoccupation of sections across 

 the Labrador Current in 1963 have been compared with tentative 

 seasonal normal values. 



4. The circulation at all levels across the Labrador Sea section has 

 been discussed concerning the distribution of temperature, salinity, 

 oxygen, volume, and heat transport observed during the 1963 post- 

 season survey.
