Method Description:
  • Total C02 Data:
    1. TCO2 Analysis Method: To measure the TCO2 concentration in seawater, a coulometric analysis system was used during all cruises. This system has been described by Chipman et al. (1993) and consists of a coulometer (Model 5011), manufactured by UIC, Inc. (Jolliet, Ill.), and a sample introduction/CO2 extraction system of LDEO design.
    2. Standardization Technique:
      1. Technique Description:
      2. Sample Volume: 250 mL
      3. CRM Info:
        1. Correction Magnitude:
        2. Batch Number: 1213
        3. CRM Analysis Info: 758 determinations were made at sea for 260 bottles of the Certified Reference Material (CRM) (batch nos. 12 and 13) yielding an average value of 1983.0 ± 1.5 µmol/kg for 166 analyses during leg P16A/P17A.
    3. Field Replicate Info: The replicate samples from 16 Niskin bottles at 8 stations were collected for shore-based reference analyses during Section P16A/P17A. The analyses were performed at the laboratory of Dr. C. D. Keeling of SIO.
    4. Poisoning Info: Immediately after sample collection, 200 �ul of 50% saturated mercuric chloride solution was added to prevent biological alteration of the TCO2 200 uL
      1. Poisoning Correction Description: Immediately after sample collection, 200 �ul of 50% saturated mercuric chloride solution was added to prevent biological alteration of the TCO2
      2. Poison Volume: 200 uL
    5. Accuracy Info: The overall precision of all TCO2 measurements is estimated to be ~±2 µmol/kg.
