that the Antarctic intermediate layer can be recognized intact in the stations taken by 

 the 'Carnegie' near the coast. The isotherm of io° C. is found at a uniform depth of 

 about 320-340 m., both in mid-ocean and near land. As no vertical movement of water 



Table XVI. Measurement of upzvelling. Data used in constructing a standard curve 

 to which inshore surface temperatures in different latitudes may be compared 



Note. Data in heavy type appear to have been unduly influenced by upwelling and have been omitted 

 from reckoning. 



Figures in column A represent means of the original data given in the preceding column (unpaired data 

 excepted) and are plotted in curve A' , Fig. 64. 



Figures in column A' were obtained from curve A' , Fig. 64, by interpolation. 



Figures in column C are taken from Schott and Schu and include interpolated values, see curve C, Fig. 64. 



The standard temperature is the mean of A' and C 



can take place without disturbing natural stratification, he argues that the extreme depth 

 likely to be affected by upwelling is 300 m. Schott (1931) associates himself with this 

 conclusion.
