Thus, on the basis of temperature, the abnormally high volume 

 transport of the West Greenland Current was being contributed 

 to more by the Irminger Current than by the East Greenland 

 Current; although the salinity maximum in the West Greenland 

 Current, as shown by figure 35, was about 0.06 °/ 00 fresher than 

 found in the occupations prior to 1949. The vigorous circulation 

 in the Labrador Sea indicated by the positive anomalies in volume 

 transport of the West Greenland Current off Cape Farewell and 

 of the Labrador Current off South Wolf Island points to the 

 greater amounts of warm West Greenland Current crossing to 

 the American side as the reason for the higher than normal 

 mean temperature of the Labrador Current off South Wolf Island. 

 This is not consistant with the results obtained for the post- 

 season occupation of the Bonavista triangle and casts further 

 doubt on the triangle results. The previously mentioned disagree- 

 ment between inflowing and outflowing heat combined with the 

 foregoing indicate that the source of the discrepancy was section 

 NW of the triangle. 



In figure 34 the frigid part of the Labrador Current over the 

 shelf is recognizable as is the West Greenland Current with its 

 cold inshore and warm offshore components. On the Labrador 

 side the tongue of maximum temperature which characteristically 

 inclines downward toward the beach at intermediate depths on 

 the offshore side of the Labrador Current is interrupted and 

 colder water was found between the warm upper layers and the 

 tongue (defined by the 3.5° isotherm in fig. 34) during this occu- 

 pation of the section. In the central part of the section is to be 

 seen the temperature minimum of the intermediate water and 

 the corresponding temperature maximum below it. The warm 

 water in the upper 1,000 meters between stations 6881 and 6883 

 is associated with the return southeastward of some of the West 

 Greenland Current. 



The fresher water over the Labrador and Greenland shelves, 

 associated with the colder parts of the Labrador and West Green- 

 land Currents, is evident in figure 35. The salinity maximum 

 core of the Irminger Current component of the West Greenland 

 Current is shown by the isohaline enclosing water of greater than 

 34.95°/ 00 . The deep salinity maximum layer between 2,000 and 

 3,000 meters was slightly fresher than usual and while thus not 

 as well defined by the 34.90% isohaline it can be traced by 

 inspection of the numerals showing the individual observations. 



The analysis of the intermediate water and the deep water of 

 this section as described in bulletin 42 of this series was continued 

 for the 1958 occupation with the following average values of 

 temperature and salinity resulting :
