Method Description:
  • Total C02 Data:
    1. TCO2 Analysis Method: TCO2 analysis was performed by extracting the inorganic carbon in the sea water samples by acidification and subsequent displacement of the gaseous CO2 into a coulorimeter cell. Two coulorimeters were used: LDEO Chipman system and AOML SOMMA system.
    2. Standardization Technique:
      1. Technique Description:
      2. Sample Volume: 500 mL
      3. CRM Info:
        1. Correction Magnitude:
        2. Batch Number: 6 = 2304.74 +/- 0.94 umol/kg
        3. CRM Analysis Info: Av. value of RM run on Chipman system was 2306.18 +/- 1.47 umol/kg (n=30)Av. value of RM run on SOMMA system was 2304.58 +/- 1.5 umol/kg (n=100)
