Dynamic Current Charts. 



The following table gives the mean densities {at\ of the water between 

 the depth of 200 metres and different levels, at all stations north of Spits- 

 bergen (and Stat. 16 west of northern Spitsbergen) that are deeper than 

 150 metres, or in a few cases than 100 metres (see Figs, i and 6). These 

 mean values were computed graphically, by means of the planimeter, from 

 the curves of density drawn for each station similarly to those of Fig. 55. 



Where the greatest depths of observation were less than 200 metres, 

 the curve of density had to be drawn hypothetically down to 200 metres, 

 and thus the values of density were estimated for the deepest layers. 



Where there were several vertical series of observations at the same 

 stations, the mean values of the most complete series were taken. 



The horizontal distribution of density at 200 metres and greater depths, 

 indicates that there is very little current at these levels. Assuming the 

 motion of the vater at the depth of 200 metres to be practically negligible, 

 Prof. Helland-Hansen and I have constructed the dynamic current charts
