There was no salinity or dissolved oxygen calibration sampling and no other information available upon which to base a recalibration. Pumped channels were removed from casts #91 to 110 because the data were bad likely due to clogged plumbing. The quality of data from CTD #0404 is lower than usual for this cruise due to low resolution in the pressure. 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 the report: 2016-31-proc.doc. --------------------------------------------------------------------------------- !--1--- ---2--- ---3--- -4-- !Pressu Fluores pH:SBE: Numb !re cence: Nominal er_o !
