The precision of the SBE dissolved oxygen channel is estimated on the basis of a comparison to bottle data to be, roughly: • ±0.5 ml/l from 0- 150db • ±0.25ml/l from 150-400db • ±0.06ml/l from 400-15000db • low by up to 0.1ml/l below 1500db For details on the processing see processing report: 2009-11-proc.doc *CALIBRATION $TABLE: CORRECTED CHANNELS !
