CTDEDIT was used to remove records near the top and bottom of the cast. --------------------------------------------------------------------------------- Data Processing Notes: ---------------------- Transmissivity, Fluorescence, Turbidity, PAR and PAR:Reference data are nominal and unedited, except that some records were removed in editing temperature and salinity. Salinity:T1:C1 values compared well with bottle samples. There was no dissolved oxygen calibration sampling, but post-cruise calibration of the sensor suggests calibration errors are <1%.
