Figure 42. Graphs showing time series of optical backscatter, transmissometer attenuation, and ADV mean echo intensity from the OBS mounted 0.23 meters above the bottom of the array, the 5-centimeter transmissometer mounted 1.20 meters above the bottom, and the ADV sample volume 0.24 meters above the bottom.


Figure 42. Graphs showing time series of optical backscatter, transmissometer attenuation, and ADV mean echo intensity from the OBS mounted 0.23 meters above the bottom of the array, the 5-centimeter transmissometer mounted 1.20 meters above the bottom, and the ADV sample volume 0.24 meters above the bottom. Dashed line marks time when tripod tipped over by strong waves and currents. Dotted lines mark times when optical sensors were cleaned by divers. Refer to the Abbreviations and Symbols section.
