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. The pH:SBE channel was removed from cast #19 because very low values suggest that the soaker bottle was left on. Downcast (CTD files) Oxygen:Dissolved:SBE data are considered, very roughly, to be: ±0.2 mL/L from 0 to 150db ±0.08 mL/L from 150db to 300db ±0.01 mL/L below 300db Warning: While the CTD fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples, particularly for casts far from shore. It is recommended that users check extracted chlorophyll values where available. Warning: The transmissometer used for casts #101 to #108 alternated between sampling at the normal rate and getting stuck on a single value for about a half second. These data are considered of lower quality than usual, though the general shape of profiles looks reasonable.
