Data Processing Notes: ---------------------- The length of the surface soaks varied greatly, with some not being long enough for the pumps to come on and equilibration of pumped channels to be achieved. Dissolved Oxygen and pH:SBE data are nominal and unedited, except that some records were removed in editing temperature and salinity and some bad near-surface dissolved oxygen data were removed. Channel Fluorescence:URU:Wetlabs was removed from casts #1001-1035 because the protective cap had not been removed. The data that remain are nominal. Some small negative values in fluorescence were set to 0 using program Calibrate. There was no calibration sampling available from this cruise. An inter-ship comparison of 2 casts from a June 2017 cruise using these sensors with a cast from a cruise that did include calibration sampling, suggested that the salinity values from this CTD were accurate but that dissolved oxygen values were likely low by up to 4%. WARNING: The pH:SBE:Nominal data should be used with caution; no field calibration data were available at the time of processing. Calibration is required for each cast to get absolute values, although general trends within a cast are likely real. For details on the processing see processing report: 2017-42-Processing_Report.doc. *CALIBRATION $TABLE: CORRECTED CHANNELS !Name Units Fmla Pad Coefficients !---------------------------------- -------- ---- ------ ------------ Fluorescence:URU:Wetlabs:ECO-AFL mg/m^3 10 -99 () (0 0) $END !--1--- --2--- ---3---- ---4--- ---5---- --6--- --7-- -8-- !Pressu Depth Temperat pH:SBE: Salinity Oxygen Oxyge Numb !re ure: Nominal :T0:C0 : n: er_o !
