3. Mean curves representing the T-S relationship for Labrador 

 Current water, mixed water and Atlantic Current water have 

 been derived for the period 1948-56 and compared with similar 

 curves for the period 1934-41 and the conditions found during 

 1956 have been compared with the means. 



4. Tentative normal seasonal variation relationships have been 

 presented for the volume transport, mean temperature and mini- 

 mum observed temperature of the Labrador Current at sections 

 F and G, located near the northeastern shoulder of the Grand 

 Banks. 



5. The temperature and salinity of the intermediate water of 

 the Labrador Sea have been examined for each of the 16 occupa- 

 tions of the South Wolf Island-Cape Farewell section since 1934. 

 While year to year variations have been large the average tem- 

 perature for the period 1948-56 was the same as for the period 

 1934-41 but the salinity has been lower in the later period. 



6. Examination of the deep water of the Labrador Sea for the 

 same periods showed a slight warming and freshening at 2,000 

 meters, an isothermal freshening at 2,500 meters and a freshening 

 accompanied by a cooling at 3,000 meters. The combined effects 

 result in about the same decrease in density at each level.
