The Reference PAR sensor produced no useful data. Channel pH:SBE data were removed from events #1 to #42 as the data looked bad. The SBE DO sensor has a fairly long response time so data accuracy is not as high when it is in motion as it is during stops for bottles. This will be especially true when vertical DO gradients are large. To get an estimate of the accuracy of the SBE DO data during downcasts (after recalibration) a rough comparison was made between downcast SBE DO and upcast titrated samples. Some of the difference will be due to problems with flushing of Niskin bottles and/or analysis errors and small mismatches in depth in the presence of large DO gradients, so the following statement likely underestimates SBE DO accuracy. Downcast (CTD files) Oxygen:Dissolved:SBE data for this cruise are considered, very roughly, to be: ±0.15 mL/L from 0-100db ±0.05 mL/L below 100db WARNING: The pH:SBE:Nominal data should be used with caution; no field calibration data were gathered. Calibration is required for each cast to get absolute values, although general trends within a cast are likely real.
