Where available, the value entered is that taken when the CTD was at the bottom of the cast; otherwise, the reading from the beginning of the cast was used. 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. *CALIBRATION $TABLE: CORRECTED CHANNELS !
