The transmissometer data alternated between sampling at the normal rate and getting stuck on a single value for about a half second. While these data are considered of lower quality than usual, the general shape of profiles look reasonable and downcasts and upcasts are in reasonable agreement. NOTE: 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. 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: ±0.2 mL/L from 0 to 100db ±0.1 mL/L from 100db to 250db ±0.04 mL/L from 250db to 400db ±0.02 mL/L below 400db For details on the processing see document: 2017-23_Processing_Report.doc. --------------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
