Depth_mean and Range_mean
Range_mean (meters)
Let A be the set of samples s in the analysis domain being considered. Then:
where
= The mean range of samples in the domain, range_mean (m) rs= The range of sample s in the domain (m) = 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 samples1 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.
