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--- ---5---- --6--- --7-- -8-- !Pressu Temperat Fluores pH:SBE: Salinity Oxygen Oxyge Numb !re ure: cence: Nominal :T0:C0 : n: er_o !
