There were 2 WetLabs CStar transmissometers in use during this cruise: Channel Transmissometer refers to sensor #1185DR (650nm - red) Channel Transmissometer:Green refers to sensor #1883DG (530nm - green) For comparison with other Institute of Ocean Sciences cruises, note that the transmissometer wavelength is 650nm unless otherwise stated. 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 for are considered, very roughly, to be: ±0.7 mL/L from 0 to 10db ±0.4 mL/L from 10 to 125db ±0.1 mL/L from 125db to 300db ±0.08 mL/L from 300db to 500db ±0.03 mL/L below 500db For event #108 data from the primary channels were bad, so the secondary channels were chosen for the OSD Data Archive. The primary channels were selected for all other CTD casts. For details on the CTD data processing see document: 2019-023_Processing_Report.doc. *CALIBRATION $TABLE: CORRECTED CHANNELS !
