are tabulated below for the Labrador Current off South Wolf Island, 

 Labrador, and for the West Greenland Current off Cape Farewell, 

 Greenland, for all available occupations of these sections. 



From comparison of the results of the measurements made in 1950 

 with those of earlier occupations it is seen that the circulation in the 

 Labrador Sea was abnormally active in 1950. The abnormal activity 

 was not confined to the Labrador Sea, since the estimate of the vol- 

 ume of flow of the East Greenland Current contribution to the West 

 Greenland Current of 3.2 is more than three times the seasonal normal 

 for early August. While the mean temperatures of both the Lab- 

 rador Current oft' South Wolf Island and the West Greenland Current 

 off Cape Farewell were close to average values, the unusually vig- 

 orous circulation resulted in outstandingly large rates of heat trans- 

 port both in the Labrador Current and in the West Greenland Current. 



In 1948 an aerial ice census was made in Baffin Bay with the bergs 

 being counted by direct visual observation. Another such census 

 was made in 1949 and in this census the bergs again were counted by 

 direct visual observation and also were photographed and the number 

 of bergs determined from the photographs. In the areas of great 

 concentrations of bergs and where the l)ergs were in the vicinity of 

 bays and fjords the photographs indicated that many bergs were 

 missed in direct visual observation. In areas away from land and 

 where concentrations were not as great, however, the direct visual 

 count was in good agreement with the photographic count. It was 

 hoped that additional censuses could be made in succeeding years so 

 that a series of at least three successive annual censuses would be 

 available for the study of the number of years which elapse from the 

 summer a berg is calved in northwest Greenland to the summer it 

 appears in the Grand Banks region, and for the study of mortality 

 rates during the different phases of this journey. No census could 

 be made in 1950 and so our series consists of the two censuses taken 

 in the summers of 1948 and 1949.
