velocity of the Cape Farewell section combined with numerical compu- 

 tation shows that this current here has a net volume of flow in a north- 

 westerly direction of 1.52 million cu. m./sec. with a mean temperature 

 of 3.93° C. This is after subtraction of a southeasterly flowing subsur- 

 face band which has a volume of flow of 1.59 million cu. m./sec. and a 

 mean temperature of 3.67° C. As this band of counter current hugs the 

 continental slope it is presumed to be composed largely of water which 

 crosses the section in a northwesterly direction adjacent and offshore 

 of it at similar or somewhat higher levels. 



Farther north, at the section extending from station 3727 across Fyllas 

 Bank to station 3736, we find a similar band of southerly current beneath 

 the surface. Here, however, the southerly current is somewhat offshore 

 of the continental slope and is presumed to be made up partly of a closed 

 eddy inshore of the counter current and partly of north-flowing water 

 crossing the section offshore of the counter-current and which also 

 crossed the Cape Farewell section. The volume of flow of the south- 

 erly current was 1.08 million cu. m./sec. with a mean temperature of 

 3.83° C. The closed eddy is probably conditioned by the bottom topog- 

 raphy in the vicinity of Fyllas Bank. The net northward volume of 

 flow past the complete Fyllas Bank section is 2.61 million cu. m./sec. 

 However, an additional half million cu. m./sec. cross the section north- 

 ward and recurve southward between stations 3727 and 3728. If this 

 be considered to be a part of the closed circulation in the central part of 

 the Labrador Sea, a comparison of the figure of 2.6 net northerly at the 

 Fyllas Bank section with the figure of 1.5 net north westerly' at the Cape 

 Farewell section requires that about 1.1 million cu. m./sec. enter the 

 Labrador Sea in the central part of the South Wolf Island-Cape Farewell 

 section either as a recurving part of the Labrador Current off South 

 Wolf Island or as a direct contribution to the Labrador Sea from the 

 outer margins of the Atlantic Current. Of these two, the latter seems 

 the more probable. 



The salinity distribution along the Fyllas Bank section is shown in 

 figure 32. The southward flowing band of current is centered near and 

 slightly inshore of station 3729. The valley and ridge just offshore of 

 Fyllas Bank are prominent features of the bottom topography here. 

 They bear the same relationship to the position of the southward flow- 

 ing band of current as was found during the occupation of similar sec- 

 tions in 1928, and it is considered they are at least a contributing cause 

 of that current. The southeasterly directed current band found in the 

 1948 occupation of the Cape Farewell section also has been present in 

 earlier occupations of that section. Although the Cape Farewell section 

 has been occupied during a greater number of years than has the Fyllas 

 Bank section, it is not possible to state with any degree of certainty 

 that the southeasterly flowing current band is tA'pical of the Cape 

 Farewell section.
