the winds along the Labrador Coast will have a decided effect on the 

 crop of berg ice appearing in the Grand Banks region. Quantitative 

 correlations between these two phenomena or betw^een any of the asso- 

 ciated intermediate steps between cause and effect have yet to be 

 determined. 



On the post-season cruise the section from South Wolf Island, Lab- 

 rador, to Cape Farewell, Greenland, which has been occupied in other 

 years, was repeated. Figure 30 shows the temperature distribution 

 along this section. As pointed out above, the Labrador Current was 

 shifted slightly offshore by abnormal wind conditions. The most

noticeable feature of figure 30 is the large area in the intermediate 

 water having temperatures of less than 3.2°. This is a characteristic 

 of this part of the Labrador Sea and is interpreted by Smith, Soule, 

 and Mosby ^ as being a relic of the previous winter's chilling not com- 

 pletely erased by the mixing processes which follow with the advent 

 of warmer weather. 



Off the Greenland coast the warm water of the Irminger Current and 

 the colder water nearer shore have a more complicated pattern than 

 usual. This apparently is the result of part of the colder East Green- 

 land Current water having been separated offshore from its main body. 

 It win be noted that stations 3069 and 3070 are plotted as a single 

 station in figure 30. After station 3069 was occupied it was necessary
