The dissolved oxygen data in the CTD files should be considered roughly • ±0.8 ml/l from 0 - 50db • ±0.3 ml/l from 50 –300db • ±0.1 ml/l from 300 - 1000db CTD Dissolved Oxygen data below 1000db are considered unreliable by the manufacturer, but fell within ±0.2ml/l in comparison to bottles. *CALIBRATION $TABLE: CORRECTED CHANNELS !
