For details on how the transmissivity calibration parameters were calculated see the document in folder "\cruise_data\documents\transmissivity". 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. The CTD deployment method was to lower the CTD to about 2m with the pumps off. The pumps were turned on, there was a wait of 40 to 70s and then the full cast was run. For some casts the two salinity channels differ markedly near the surface after the pumps came on; this may be due to bubbles from the CTD system. Below 10m the two salinity channels track well. 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: ±0.4 mL/L from 0 to 100db ±0.2 mL/L from 100db to 200db ±0.1 mL/L from 200db to 500db ±0.04 mL/L below 500db For details on the processing see document: 2016-12_Processing_Report.doc. --------------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
