The entry in the headers is based on the position of cast #93 at the same station. CTDEDIT was used to remove surface records to 1.6db. ******************************************************************* The water depth in the header was taken from the log book where available, but there were often large differences between the readings at the beginning and end of casts. 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 !
