Melville ADCP Checklist

Cruise name: ______________________   Date:_____________________

The default is to start up with bottom track OFF. Any time the water is shallower than 500m, the ADCP Operator should taggle the settings to Bottom Track ON, and restart data acquisition. Usually, for most of the cruise, Bottom Track will be off. Although the OS75 can run in BB mode, we are choosing to only collect data in NB mode. Fill in the values used at the start of the cruise.
