The coefficients of -0.29, -0.27, and -0.33 in February, March, 

 and May appear quite liijrh, but the precipitation at Upernivik in- 

 volves other factors such as the distribution of the pressure, and of 

 course, attending winds. The last variate considered was the tem- 

 perature durin<r tlie summer months at Upernivik, (&) givinir the 

 followiuir correlation coefficients:

These values are so small that we may discard any effect of summer 

 temperatures along the ice-fjord coast of west Greenland, so far as 

 any effect of the iceberg distribution is concerned.

Icebergs and Atmospheric Pressures 



FicruE 117. — The graph olearly shows a definite relation between the annual nuni- 

 lier o£ icebergs south of Ninvfounclland (the ordinate scale 0-10), and the depar- 

 tures from the normal atmospheric pressure conditions over the northwestern North 

 Atlantic. The abscissa values were obtained by substitution of the pressure data 

 in the regression equation on p. 18S. The numbers on the graph indicate the par- 

 ticular year investigated. 



The correlation coefficients determined by the foregoing methods 

 indicate that of all tlie variates considered, the atmospheric pressure 

 difference between Ivigtut. Greenland, and Belle Isle. Newfound-
