There are only 3 casts with titrated dissolved oxygen samples that could be compared to the SBE Dissolved Oxygen data for sensor #1438, and one of them looked significantly different in the comparison from the other 2. Recalibration of DO was based on the 2 casts that looked similar. There are insufficient data to make a precision estimate. For SBE Dissolved Oxygen sensor #1438 values below 2200db were replaced by pad values because there is evidence of significant hysteresis. The salinity from CTD #0443 showed evidence of flow rate problems in the top 200m; the 2-sided noise caused by that was minimized by bin-averaging. For details on the processing see processing report: 2010-14-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. The hysteresis noted in the original processing remains, and the quality of the data is still considered of lower quality than usual. 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 2010-14-proc.doc, along with detail about how the reprocessing was done. *CALIBRATION $TABLE: CORRECTED CHANNELS !
