Ciirrent at Cape Farewell is small enough to be completely masked by 

 the large year to year variations, its mean temperature does seem to 

 have a seasonal variation with a pronounced increase in mean tem- 

 perature during the months from June to September. As this period 

 of the year includes all but two of the recorded occupations of the Cape 

 Farewell section the data do not lend themselves to analysis by Fourier 

 series. Figure 37 shows the available observations. In it the values of

As the heat transfer of the West Greenland Current past Cape Fare- 

 well is usually the major source of water-borne heat entering the circu- 

 latory systems of the Labrador Sea and Baffin Bay, the section has
