Recalibration of SBE Dissolved Oxygen: The SBE sensor calibration drifted significantly during the cruise, so the data were divided into 2 sections for recalibration. Where there were insufficient data to enable reliable recalibration the channel was removed. The dissolved oxygen data in the CTD files should be considered, roughly • ±0.8ml/l from 0 – 75db • ±0.4ml/l from 75 – 175db • ±0.1ml/l below 175db • The manufacturer considers the sensor unreliable below 100db ---------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
