Class of Data:  Surface ocean carbon dioxide concentrations

Dataset Identifier:  EX1038

Expocode: 33KF20101028

Measurement platform identifier:  EX1038/Explorer

Data quality issues:

     STD1 analyses were not used in the calibration due to lack of data points.

     Standard Gases and Reference Gas:  The three standard gases come from CMDL
     in Boulder and are directly traceable to the WMO scale.  The zero gas
     is a non-calibrated gas from a commercial company.  Any value outside the
     range of the standards should be considered approximate (5 ppm).
     While individual data points above 550 or below 300 may less accurate,
     the general trends should be indicative of the seawater chemistry.  
     The standards used on the cruise are:

         STANDARD            TANK #       CONCENTRATION       VENDOR
           STD1                                 0.00         Commercial
           STD2              CA07952          549.89           CMDL
           STD3              CA02040          319.82           CMDL  
           STD4              CA02030          377.14           CMDL                          

     Units:  All xCO2 values are reported in parts per million (ppm) and fCO2
     values are reported in microatmospheres (uatm) assuming 100% humidity at the
     equilibrator temperature.
