The fluorometer values drifted during the previous cruise that used this equipment. That drift continued starting with dark values early in the cruise of about 0.2ug/L and rising to about 0.4 ug/L by cast #177. At that point the tubing and pump were cleaned and dark values then returned to the normal range. A time-dependent correction was applied to casts #2 to #177 based on values at 2000m with a small adjustment to ensure there would be no negative values. The correction was an offset that was applied to the whole profile. 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: ±0.5 mL/L from 0 to 125db ±0.1 mL/L from 125db to 500db ±0.05 mL/L from 500db to 1000db ±0.02 mL/L below 1000db For details on the processing see document: 2017-09_Processing_Report.doc. --------------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
