CTDEDIT was used to remove records corrupted by shed wakes and to clean salinity. --------------------------------------------------------------------------------- Data Processing Notes: ---------------------- Transmissivity, Fluorescence and PAR data are nominal and unedited except that some records were removed in editing temperature and salinity. For details on how the transmissivity calibration parameters were calculated see the document in folder "\cruise_data\documents\transmissivity". 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. Downcast 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 300db ±0.1 mL/L from 300db to 800db ±0.02 mL/L below 800db There were 2 Biospherical/Licor PAR sensors. The one identified as PAR refers to a new sensor (S/N 70613) and PAR1 refers to an older sensor (S/N 4615). For details on the processing see document: 2016-47_Processing_Report.doc. --------------------------------------------------------------------------------- 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. --------------------------------------------------------------------------------- *CALIBRATION $TABLE: CALCULATED CHANNELS !
