Wecoma ADCP Checklist

Cruise name: ______________________   Date:_____________________

In the OS75 Instrument Setup table, the first column contains the deep water (> 500 m) setup defaults and the second column contains the shallow water setup. The only difference between the two is Bottom Track, which is toggled on in shallow water. 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. For the WH300, BT is just a toggle, turn ON when water depth is < 500 m.
