PAR data were removed from casts #31 to 75 since the signal was low and spiky. The precision of the SBE dissolved oxygen channel is difficult to estimate because the comparison with bottles was noisy, but roughly, the DO should be considered: • ±0.6ml/l from 0- 25 db • ±0.4ml/l from 25-125 db • ±0.2ml/l below 125db ************************************************************************************* The SBE Dissolved Oxygen sensor behaved oddly for casts 12-41, with data offset from those of the other casts when differences between bottles were plotted against DO values. Similar problems were noted during cruises 2010-36 and 2010-14 in July and August 2010. Using an appropriate recalibration brought those casts into reasonable agreement with the other casts. For casts without titrated dissolved oxygen sampling, a decision on how to recalibrate was based on the noise level in the raw oxygen voltage. The casts with the offset all had a higher noise level for all the cruises that had this problem. ************************************************************************************* For details on the processing see processing report: 2010-20-proc.doc. *CALIBRATION $TABLE: CORRECTED CHANNELS !
