Table 2. — Average velocity of the drift and the percentage of ship's ob- 

 servation reported towards each of the cardinal and inter- 

 cardinal points of the compass in the area east of the Hawaiian 

 Islands computed from data given in the Atlas of Surface Currents 

 of the Northeastern Pacific (H. 0. 570). Average drift was taken 

 from H. 0. 1401 



To show the short-period fluctuations in the currents incident to the 

 islands that could have been expected if the effect of the wind were assumed to be 

 Instantaneous, tables of daily wind and current (tables 3-5) were computed for the 

 week preceding and for the period of the cruises. The choice of the 1-week period 

 before the cruise was purely arbitrary, and the data are merely included as back- 

 ground. The winds were computed from the pressure gradients indicated by the U. S. 

 Weather Bureau Synoptic Weather Maps and in turn were used to compute the currents.
