Data Processing Notes: ---------------------- The SBE data are considered of lower quality than normal because 24 scans were averaged in acquisition. These averages may contain spikes that would normally be removed in processing and might be systematic in nature. Fine-tuning of alignment settings and CELLTM correction are also less sensitive with smoothed data. Unfortunately the same error was made on several other cruises using the same equipment, so we can not rely on settings determined from those data sets. Given the area is in protected waters and the CTD is believed to have worked well with few spikes, it is likely the errors caused by this problem are small. Fluorescence, PAR and Transmissivity data are nominal and unedited. For details on how the transmissivity calibration parameters were calculated see the document in folder "\cruise_data\documents\transmissivity". SBE DO calibration was done using the method described in the SeaBird Application Note #64-2. The tests for accuracy of Oxygen:Dissolved:SBE data are less reliable than usual, but the data are considered, very roughly, to be: ±1mL/L from 0 to 20db ±0.4mL/L from 20 to 100db ±0.1mL/L below 100db For details on the processing see processing report: 2011-10-proc.doc. *CALIBRATION $TABLE: CORRECTED CHANNELS !Name Units Fmla Pad Coefficients !------------------------------ -------- ---- ------ ------------ Fluorescence:Wetlabs:ECO-AFL mg/m^3 10 -99 () (0.61E-01 1) $END !--1--- ---2---- --3-- ---4--- --5--- --6--- ---7---- --8--- --9-- -10- !Pressu Temperat Trans Fluores PAR PAR: Salinity Oxygen Oxyge Numb !re ure: missi cence: Refere :T1:C1 : n: er_o !
