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° fbr 
each degree of latitude.

Since the value of Z, the distance between stations, is expressed in 
kilometers, a conversion table of nautical miles to kilometers is 
included herewith:
