NO. 4 TEMPERATURE \ ARIATIONS IN THE NORTH ATLANTIC 



47 



The march of temperatures found by Liepe for his eight stations 

 gives the impression that he obtained more accurate values than 

 those of Petersen for the single stations since the curves for the 

 different stations agree better (see fig. 15). Compared with 

 our curves for the years common to the two series of observa- 

 tions, that is from 1898 to 1903, there is a good correspondence 

 in the curves for our eastern and southeastern fields concerning

which we shall speak again. This was to be expected, because the 

 hydrographic relations in the region investigated by Liepe are much 

 more regular than in the greater part of the region investigated by 

 Petersen, and in this respect Liepe's region is similar to our eastern 

 and southeastern one. 



The principal conclusion of Liepe in relation to the causes of the 

 variations agrees with Petersen's view that they are to be referred 

 to the winds.
