CTDEDIT was used to remove surface records to 2.6db and records corrupted by shed wake around 30db and a few records from the bottom of the cast; salinity was cleaned lightly. --------------------------------------------------------------------- Transmissivity and fluorescence are nominal and unedited except that some records were removed in editing temperature and salinity. The dissolved oxygen data in the CTD files should be considered: • ±0.8ml/l from 0 – 50db • ±0.4ml/l from 50 to 200db • ±0.2ml/l below 200db • data below 1200db are considered unreliable by the manufacturer. *CALIBRATION $TABLE: CORRECTED CHANNELS !
