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 SBE 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. Channel Salinity:T1:C1 was found to be lower than bottles by approximately 0.003psu, but delayed analysis and incomplete flushing of Niskin bottles is likely to result in bottle values being higher than ambient salinity values by roughly 0.005psu, so the CTD salinity was likely high by roughly 0.002psu. During use in the previous cruise the secondary salinity was considered to be low by about 0.0005psu. No recalibration was applied due to the uncertainty in the comparisons. Salinity is likely within 0.002psu. 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: ±0.40 mL/L from 0-20db except in areas of very large DO gradients ±0.15 mL/L from 200db-500db ±0.04 mL/L below 500db For details on the processing see the report: 2021-012_Processing_Report.doc. ------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
