Depth_mean and Range_mean

Range_mean (meters)

Let A be the set of samples s in the analysis domain being considered. Then:

where

r̄	=	The mean range of samples in the domain, range_mean (m)
rs	=	The range of sample s in the domain (m)
εs	=	0 if sample s is: above an Exclude above line and/or below an Exclude below line and/or a no-data sample and Include the volume of no-data samples is not selected Note: No-data samples may occur in a number of ways (no-data samples, samples within applied bad data (no data) regions and samples in pings with a bad line status). For further information refer to About analysis domains: Analysis based on regions and samples. 1 otherwise, including below threshold data.

Depth_mean (meters)

Depth_mean is the projection of Range_mean onto the vertical axis taking transducer geometry into account. For a vertically mounted transducer pointing directly downwards, Depth_mean and Range_mean differ by the transducer draft only.
