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



during storm 4. 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 10-min intervals, and turbidity at 81 cm (upper) and 

 33 cm (lower) above the seafloor.
