It is often desirable to express the velocities at the various levels 

 of observation graphically in the form of a current diagram, in which 

 case it is customary to measure the velocity units along the abcissa 

 and the depths along the ordinate. The graphic representation of 

 the current between stations 205 and 206 is shown by Figure 13. 



Table VI is a copy of a table (Table 12), which first appeared in 

 a contribution by Sandstrom and Helland-Hansen, in "Report on 

 Norwegian Fishery and Marine Investigations," Volume II, No. 4, 

 Bergen, 1903. It contains the computed values of 2 w sin <^ 10^ for 

 each degree of latitude.

Since the value of i, the distance between stations, is expressed in 

 kilometers, a conversion table of nautical miles to kilometers is 

 included herewith :
