The precision of the SBE dissolved oxygen channel is difficult to estimate because the comparison with bottles was complex and noisy, but roughly, for the inshore casts DO should be considered: • ±0.4ml/l from 0-50 db • ±0.2ml/l from 50-125 db • ±0.02ml/l below 125db *************************************************************************** WARNING: THE data in the OXYGEN:DISSOLVED:SBE channel is of lower quality than usual. The membrane was found to be torn when it was examined at the factory in December 2010. For this cruise it did a poor job of tracking DO in areas of high variability. The worst effects were seen between 50db and 300db in the offshore casts beyond the 200m contour. This was an inshore cast so the effects were less severe. *************************************************************************** For details on the processing see processing report: 2010-15-proc.doc. ********************************************************************* In June 2011 it was discovered that the wrong information was used for conversion of the SBE Dissolved Oxygen sensor data for CTD #0443. Sensor #1483 was actually used for this cruise. The SBE Dissolved Oxygen channel was reprocessed. A new recalibration scheme was found by rerunning the bottle comparison. The files were then merged with all the other channels from the original processing. Previous warnings about the quality of the SBE Dissolved Oxygen remain valid. Note that the calibration information in the SeaBird headers for the DO sensor refers to the wrong sensor. The correct information can be found at the end of the processing report 2010-15-proc.doc, along with detail about how the reprocessing was done. *********************************************************************** *CALIBRATION $TABLE: CORRECTED CHANNELS !
