TABLE 107. THE WIND FACTORS OF ICEBERGS OF VARIOUS DISPLACEMENTS 



Now let us assume that the iceberg actually drifts in the wind current. Of course, an ice- 

 berg will be carried along by this current at an average velocity corresponding to its underwater 

 and above-water contours. 



The velocity of the wind current, as follows from Ekman's theory, decreases very rapidly 

 with depth and in the high and middle latitudes at a depth of 50 to 100 m it reverses its direction, 

 becomes practically zero. Thus, the deeper an iceberg sits in the water, the slower will be the 

 drift speed imparted by the current and the more it will be deflected to the right.
