GEOGRAPHICAL DISTRIBUTION OF TEMPERATURE— SEA-LEVEL.

Ross Sea it was actually on the Barrier and appears to have experienced in consequence 

 true Barrier temperature.s as will be seen from the following table : — 



Table 12. 



Ti'mperiUnre at Framheim 1911-12. 



It will be shown later that Framheim shares with other parts of the Barrier a large 

 daily range of temperature. Now at Framheim temperature observations were made three 

 times a day at 8 hours, 14 hours and 20 hours. The 14 hours' observations fell at the 

 time of the daily maximum temperature and as there were no corresponding observations 

 taken at or near the minimum, the mean of the observations spaced as these are must be 

 too high. Hence in calculating the mean temperatures given in the above table the 14 hours' 

 observations have been rejected and the observations at 8 hours and 20 hours only consi- 

 dered. There can be no doubt that the mean temperatures calculated in this way are nearer 

 the true values than if all three observations had been taken into account. 



Temperatures at Cape Adare.— T^\i'i observations available for determining the mean tem- 

 peratures at Cape Adare will be discussed later (page 83), we will use here the mean 

 values which will be then derived. 



Table 13. 



Temperature at Cape Adare. 



The most interesting and important conclusion to be drawn from this table is that during 

 the winter from June to Augu.st there is practically no difference between the mean tem- 

 perature at Cape Adare and at Cape Evans although they are separated by more than six 

 degrees of latitude. The difference is greatest during the three months February, March, and 

 April, being then about 15°F.
