There was a problem with the salinometer used to analyze samples for this cruise. Tests were run and are described in document “Salinometer-68572 study_20Mar2019.xlsx”. They established a linear correction to be applied to all salinity analyzed on salinometer #68572 between January and March 2019. Based on those corrected bottle values and the history of the sensors, the CTD salinity values are believed to be within +/-0.002psu. Dissolved oxygen was calibrated using the method described in SeaBird Application Note #64-2, June 2012 revision, except that a small offset in the fit was allowed. 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, so the following statement likely underestimates SBE DO accuracy. Downcast (CTD files) Oxygen:Dissolved:SBE data are considered, very roughly, to be: ±0.40 mL/L from 0 to 10db ±0.20 mL/L from 10 to 75db ±0.10 mL/L from 75 to 200db ±0.06 mL/L below 200db WARNING: The pH:SBE:Nominal data should be used with caution; no field calibration data are available. Calibration is required for each cast to get absolute values, although general trends within a cast are likely real.
