The data from these sections, while not numerous, have per- 

 mitted the development of some tentative normal seasonal varia- 

 tion relationships for a part of the year. Those for the West 

 Greenland Current off Cape Farewell were published in bulletin 

 35 of this series. These data for the section across the Labrador 

 Current off South Wolf Island, Labrador, have so far been treated 

 as of a common date and average values are used for comparison 

 with those for an individual occupation. Tentative normal seasonal 

 variation curves for sections T, U and W have been published in 

 bulletin 36 and those for the Bonavista triangle appear in bulletin 

 39. Data from sections H and F 2 are still insufficient for the de- 

 velopment of even tentative normals. Figure 18 gives the approxi- 

 mate normal seasonal variation relationships at sections F and G. 

 The seasonal increase in volume transport for section F does not 

 agree with the seasonal decrease found for section G. All three 

 sections of the Bonavista triangle show a seasonal increase in 

 volume transport. It is to be expected that section F would show 

 either a seasonal decrease or a smaller seasonal increase than 

 that at the Bonavista triangle. These curves are therefore looked 

 upon with suspicion and additional data may show that the sea- 

 sonal decrease at section G is less than shown in figure 18 and 

 that the volume transport at section F normally has a seasonal 

 decrease.
