The first 4321 records so that DELETE would select the best surface data. CTDEDIT was used to remove records from the surface and from the bottom 5db of the cast; salinity was cleaned. --------------------------------------------------------------------- The fluorescence data were frequently offscale (>5mg/m3). 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 !
