Figure 3-9. Time series plot of near-bottom current data and surface wave data during the 3- 

 month measurement period. The following data are presented on individual tiers 

 starting from the top: hourly current speed, hourly current direction, hourly speed 

 after the mean current vector has been removed from each of the three deployment 

 records, hourly current direction after the mean current vector has been removed, 

 current vectors after the mean has been removed, significant wave height, and 

 peak wave period.
