Figure 30. — Potential temperature-salinity relationship found beneath the 

 Atlantic Current south of the Grand Banks 23-26 May 1958 (solid line) 

 compared with the relationship reported by the Woods Hole Ocean- 

 ographic Institution for the deep water west of Bermuda (broken line). 

 Last two digits of station number identify location of observation. 



Woods Hole Oceanographic Institution, as mentioned in the dis- 

 cussion of methods of measurement. 



An inspection of figure 29 will show the components indicated 

 in figure 26. The southernmost easterly flowing current is A in 

 figure 26. This was computed to have a volume transport (ex- 

 pressed in millions of cubic meters per second) of 48.6. South 

 of this is the westerly return toward Bermuda, B. The section 

 did not completely cross B. By computation the part that is on 

 the section is 7.6 and it is estimated that another 2.2 lies south 

 of the section for an estimated total B of 9.8. Northward of A 

 a westerly flowing band represents the part of A which recurves 

 to the northwestward as D. By computation this amounted to 

 5.6. By subtraction of D and B from A the southerly contribution 

 to the eastward, C, was 33.2. The northernmost band of current, 

 flowing westward, is the Labrador Current, F. Some uncertainty
