Echosounder Noise Suppression

Applies to ASL data products.

This option only applies to the ASL Zooplankton Acoustic Profiler (ZAP) echosounder, but does appear as option for all ASL echosounders (due to a limitation on how we can display the option). It will have no effect on echosounders other than the ASL ZAP. An ONC-customized noise suppression algorithm is applied to the ZAP data by default, this option allows the user to switch it off and reproduce ASL's standard processing of the data.
