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 +/-0.004psu. Two different fluorometers were used during this cruise but both malfunctioned producing very low values compared to extracted chlorophyll samples. The fluorescence channel was removed for both sensors since values are <50% of extracted chlorophyll values for 3ug/L < CHL < 6ug/L range and <25% for CHL > 6ug/L. Most data were well below both criteria. 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: ±0.4 mL/L from 0 to 50db ±0.25 mL/L from 50 to 150db ±0.10 mL/L from 150db to 300db ±0.02 mL/L below 300db WARNING: The pH:SBE:Nominal data should be used with caution; no field calibration data were available at the time of processing. Calibration is required for each cast to get absolute values, although general trends within a cast are likely real. Channel pH:SBE was removed from cast #52 because the buffer bottle was left on during the cast.
