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: • ±0.5 ml/l from 0– 50db • ±0.4 ml/l from 50–150db • ±0.2 ml/l below 150 db The salinity appears to have been low by about 0.012 units, but there were some problems with the salinometer, so no recalibration has been applied pending results of a post-cruise calibration of the temperature and conductivity sensors. UPDATE (April 2009): Post-cruise calibration reports indicate that the drifts in the T and C sensors were very low and that the combined effect on salinity would lead to errors of <0.001 for this cruise. So no recalibration is required. *CALIBRATION $TABLE: CORRECTED CHANNELS !
