Figure 3-1 la. Time series plot of surface wave and near-bottom current and turbidity data 



during storm 1 . The following data are presented on individual tiers starting from 

 the top: significant wave height and peak wave period, near-bottom water 

 temperature, 1-min averaged current speed, the standard deviation in current 

 speed over 1 -min periods at 1 0-min intervals, and turbidity at 8 1 cm (upper) and 

 33 cm (lower) above the seafloor.
