CLEAN was run afterwa CTDEDIT was used to remove surface records to 5.6db and records corrupted by shed wakes around 7db and 25db and a few from near 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 fluorometer was unpumped which may reduce the data quality for those casts with highly variable descent rates. See file 2008-04-proc.doc for details on how the Oxygen:Dissolved:SBE data were recalibrated. The Dissolved:Oxygen:SBE calibration can at best be considered ±2%, with possible systematic errors of ±0.2ml/l near the surface and ±0.12ml/l below 200m. Non-systematic errors in the SBE Dissolved Oxygen due to such factors as poor time response and variations in transit time cannot be assessed due to problems with calibration bottle analyses, but typically such errors are found to range from ±0.5ml/l near the surface to ±0.1ml/l below 200m. Salinity data were not recalibrated; the calibration is considered to be ±0.001. *CALIBRATION $TABLE: CORRECTED CHANNELS !
