Fluorescence:URU:Seapoint – The data are uncalibrated and unedited. Transmissivity: The data are nominal and unedited. Based on post-cruise calibrations of temperature and conductivity, the salinity data are considered to be within 0.001. No recalibration was applied to the salinity. The dissolved oxygen data were recalibrated based on comparison with bottles. The SBE dissolved oxygen data in the CTD files appear to be, roughly, within: • ±0.6ml/l from 0 - 200m • ±0.2ml/l from 200 - 500m • ±0.1ml/l from 500 - 1500m • ±0.02ml/l below 1500m *CALIBRATION $TABLE: CORRECTED CHANNELS !
