CTD Data Processing Notes: -------------------------- Conductivity, Transmissivity and Fluorescence are nominal and unedited except that some records were removed in editing temperature and salinity. NOTE: While the 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. 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. 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 this cruise are considered, very roughly, to be: <0.08mL/L for pressure <200db <0.04mL/L for pressure between 200-300db <0.02mL/L for pressure >300db For details on the processing see the report: 2024-019_Processing_Report.doc. --------------------------------------------------------------------------------- *CALIBRATION $TABLE: CALCULATED CHANNELS !
