Salinity calibration is based on calibration sampling during 2006-10 Leg 1. Dissolved oxygen calibration is based on the results of 2005-32 for which errors were estimated to be ±0.5ml/l between 0 and 50m, ±0.3ml/l between 50 and 150m and ±0.1ml/l below 50m. There are likely to be significant differences for this cruise due to calibration drift and a lower descent rate for the CTD. Transmissivity and fluorescence are nominal and unedited except that some records were removed in editing temperature and salinity. It was noted in the log book that the syringe was dry; no problems were noted in the salinity data. *CALIBRATION $TABLE: CORRECTED CHANNELS !
