CTDEDIT was used to remove surface records and records corrupted by shed wakes; salinity was cleaned. --------------------------------------------------------------------- Transmissivity and fluorescence are nominal and unedited except that some records were removed in editing temperature and salinity. The precision of the SBE dissolved oxygen channel is estimated on the basis of a comparison to bottle data to be, roughly: • ±0.5 ml/l from 0- 150db • ±0.25ml/l from 150-400db • ±0.06ml/l from 400-15000db • low by up to 0.1ml/l below 1500db For details on the processing see processing report: 2009-11-proc.doc *CALIBRATION $TABLE: CORRECTED CHANNELS !
