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 very close to bottle samples. The SBE DO sensor hysteresis setting and calibration appeared to change suddenly between casts #128 and #133. This might be related to problems encountered in the previous cast at the same site as #133. The change was small and principally affected low oxygen values. The later casts were reconverted with different hysteresis parameters. Separate recalibration schemes were applied to the 2 groups of casts. 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 Dissolved Oxygen and upcast titrated samples. Some of the difference will be due to incomplete flushing of Niskin bottles and imperfect matches in levels from the two data sets as well as errors in sample analysis/collection, 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: ±0.60 mL/L from 0-100db except in areas of very large DO gradients ±0.20 mL/L from 100db-500db ±0.04 mL/L below 500db For details on the processing see the report: 2022-022_Processing_Report.doc. ------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
