The volume transport, mean temperature and resulting heat 

 transport for all occupations of the sections across the Labrador 

 Current off South Wolf Island and the West Greenland Current 

 off Cape Farewell that have been considered in our discussions 

 are listed in table 2. For the most part these measurements were 

 made by the International Ice Patrol from the Marion in 1928, the 

 General Greene 1931 to 1941 and the Evergreen 1948 to 1956. 

 Two occupations of the Cape Farewell section, one by the Godthaab 

 in 1928 and one by the Meteor in 1935, are included. For the 

 section across the Labrador Current off South Wolf Island a 

 tabulation of the minimum observed temperature is included and 

 average values are presented. Averages are not listed for the 

 West Greenland Current since there appears to be seasonal varia- 

 tions in the volume transport of the parent components (Irminger 

 Current and East Greenland Current) having maximum rates of 

 change in the summertime. 



Figure 20 shows the dynamic topography in the vicinity of the 

 section from South Wolf Island, Labrador, to Cape Farewell, 

 Greenland found during the 1956 post season cruise. Figures 21 

 and 22 show the distribution of temperature and salinity along 

 this section for the same occupation. In figure 21 the Labrador 

 Current is to be seen with its characteristic temperature minimum 

 over the shelf and its horizontal temperature gradient above the 

 continental slope. The West Greenland Current also is recogniz- 

 able from its characteristic cold inshore water and warm offshore 

 band. In the intermediate water of the Labrador Sea the tempera- 

 ture minimum, which is considered to be a relic of the previous 

 winter's cooling, was less pronounced and was warmer than usual. 

 In figure 21 two small areas within which the temperature was 

 less than 3.3 indicate the location of this minimum. In earlier 

 bulletins of this series the different occupations of the section 

 have been described as warm years or cold years according to the 

 temperature found in the minimum and the cross sectional extent 

 of the minimum. By this method the 1956 occupation would be 

 classified as warm along with those of 1940, 41, 48, 49, 51, 52, 

 and 53 while the cold years were 1934, 35, 36, 38, 39, 50, 54 and 55. 



An attempt has been made to arrive at a more specific and 

 numerical characterization of the intermediate water by taking 

 the average of all temperatures observed between depths of 450 

 and 1,750 meters from all stations which lie offshore of the 

 Labrador Current and the warm water of the West Greenland 

 Current for each occupation. For 1956 this would include stations 

 6325-29. The averages of all the corresponding salinities for each 

 occupation were also computed. These average temperatures have 

 been plotted against their corresponding average salinities in
