22. Comparison between the "Michael Sars" station 90 (in 1910) at 46° 58' N., 19° 6' W. and tlie 

 "Armauer Hansen" station 42 (in 1922) at 46° 56' N., 18° 54' W. 



When we consider that /^S, at the depths in ques- 

 tion in the eastern part of the North Atlantic, gets rela- 

 tively high positive values where there is an admixture 

 of water from the Mediterranean, while water from the 

 northwestern part has negative values (cf. the ciiarts p. 

 97*) we may venture to infer that practically no water 

 from the Mediterranean was present at the "Armauer 

 Hansen" station at 800 metres, though such water exerted 



quite an apreciable influence at this depth at the "Mi- 

 chael Sars" station some few miles to the north-west. 

 This can hardly be explained by local variations; it must 

 probably be attributed to annual variations. At 1000 

 metres hardly any difference exists between the two sta- 

 tions as regards the effect of water from the Mediter- 

 ranean, though some difference appears in the absolute 

 values of temperature and salinity. 



Turning to Fig. 22, we have to make proper allow- 

 ance for the uncertainty in the construction of the curves, 

 which is due to the fact that the depths of observation 

 (below 600 metres) are relatively few and more unequal 

 at the two stations than in the cases illustrated by Figs. 

 21 and 23. We find, nevertheless, that there are prob-
