Figure 28. — Current diagram 1 was made from the three stations taken across the temperature wall 

 on March 21, 1930. Apparent disagreement is seen between the currents indicated by dynamic 

 observations and by actual berg drift along the temperature wall. The dynamic currents probably 

 actually existed superposed upon the rapid general drift indicated by the movement of the ice
