The CTD deployment protocol varied through the cruise: For most casts the CTD was lowered to approximately 2-3m and held there for 1 to 2 minutes before the full cast began. For casts #71, 72, 86, 87, 88 and 89 the CTD was soaked for 30s at the surface, lowered to 10m for a 60s soak and then raised to 1.5-2m for another 30s soak; the full cast then followed. 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. 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. Much 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 this cruise are considered, very roughly, to be: ±0.30 mL/L from 0-100db ±0.20 mL/L from 100-200db ±0.04 mL/L from 200-500db ±0.02 mL/L below 500db For details on the processing see the report: 2021-069_Processing_Report.doc. *CALIBRATION $TABLE: CORRECTED CHANNELS !
