Figure '2-2 shows the location of the oceanographic stations occupied 

 in the Labrador Sea, Davis Strait, and Baffin Bay on the postseason 

 cruise. Figure 23 shows the dynamic topography of the sea surface 

 rehitive to the 1,500-decibar surface based on these stations. Only 

 the major features of the current pattern are shown since the dis- 

 tances between the different sections are too great to develop the 

 details. The shoal on the Labrador shelf off Hamilton Inlet is prob- 

 ably responsible for the irregular course of the dynamic isobaths of 

 1454.78 and 1454.79. The total Labrador Current passing the South 

 Wolf Island section from the beach out to station 3943 was computed 

 at 5.16 million cubic meters per second with a mean temperature of 

 about 2.3° C. Of this amount 1.45 million cubic meters per second 

 are to be seen recurving northeastward between stations 3943 and 

 3947. By difference, this leaves 3.7 continuing southward. Tliis 

 ligure is about 0.7 less than the volume of flow found at the northern 

 section of the second occupation of the triangle about 2 weeks earlier, 

 so it is presumed that about half of the 1.45 moving northeastward 

 between stations 3943 and 3947 came from the vicinity of Flemish 

 Cap and some of this probably represents a contribution from the 

 outer margins of the North Atlantic eddy. 



Station 3951 seems to be the center of a closed eddy. The volume of 

 flow between stations 3947 and 3951 is computed as 2.63, which is 1.18 

 million cubic meters per second greater than the 1.45 found between 

 stations 3943 and 3947, whence 1.18 has been deducted from the 3.70 

 found to be flowing northwestward between station 3951 and the 

 beach at Cape Farewell to give 2.52 million cubic meters per second 

 as the volume of flow of the West Greenland Current continuing 

 northwestward along the Greenland coast. Of this 2.52 about 1.45 

 has been contributed from the southwestward, some of it from the 

 closed circulation in the Labrador Sea and some of it as a direct con- 

 tribution from the outer margins of the Atlantic Current, leaving 

 only about 1.07 as the contribution to the West Greenland Current 

 from the east of Cape Farewell. The mean temperature of this con- 

 tribution from east of Cape Farewell was computed to be 3.22° C. and 

 that of the West Greenland Current 3.62° C. 



Farther north along the west coast of Greenland the section run- 

 ning from the deep water of the Labrador Sea to Fyllas Bank was 

 occupied again. This section has again presented difficulties in the 

 reconciliation of the results obtained there with other observations. 

 This time the volume of flow computed between station 3966 and the 

 beach, 3.95 million cubic meters per second, is about 1.5 larger than 

 would have been expected from the results obtained off' Cape Fare- 

 well, and is about 1.0 larger than the volume of flow southward past 

 the Loks Land section between station 3956 and the beach. The most 

 reasonable picture consistent with the other observations would re-
