Method Description:
  • Total C02 Data:
    1. TCO2 Analysis Method: The TCO2 analysis was done by coulometry with two analytical systems (PMEL-1 and PMEL-2) used simultaneously on the cruise. Each system consisted of a coulometer (UIC, Inc.) coupled with a SOMMA.
    2. Standardization Technique:
      1. Technique Description: The coulometers were each calibrated by injecting aliquots of pure CO2 (99.995%) by means of an 8-port valve outfitted with two sample loops (Wilke et al.,1993). The instruments were calibrated at the beginning of each station with a set of the gas loop injections. Subsequent calibrations were run either in the middle or end of the cast if replicate samples collected from the same Niskin, which were analyzed at different stages of analysis, were different by more than 2 umol kg-1.
      2. Sample Volume: 300 mL
      3. CRM Info:
        1. Correction Magnitude:
        2. Batch Number: 67
        3. CRM Analysis Info: Secondary standards were run throughout the cruise on each analytical system; these standards are Certified Reference Materials (CRMs) consisting of poisoned, filtered, and UV irradiated seawater supplied by Dr. A. Dickson of Scripps Institution of Oceanography (SIO), and their accuracy is determined shoreside manometrically. On this cruise, the overall accuracy and precision for the CRMs on both instruments was -1.7+/-0.8 umol kg-1 (n=63) and -2.4+/-0.7 umol kg-1 (n=64) for PMEL-1 and PMEL-2 respectively.
    3. Field Replicate Info: Duplicate samples were drawn from 256 bottles and interspersed throughout the station analysis for quality assurance of the coulometer cell solution integrity. The average of the absolute value of the difference between duplicates was 1 umol kg-1 for both systems. No systematic differences between the replicates were observed.
    4. Poisoning Info: Samples were corrected for the addition of poison by a factor of 1.00066 0.2 mL of 50% saturated solution
      1. Poisoning Correction Description: Samples were corrected for the addition of poison by a factor of 1.00066
      2. Poison Volume: 0.2 mL of 50% saturated solution
    5. Accuracy Info: the overall accuracy and precision for the CRMs on both instruments was -1.7+/-0.8 umol/kg (n=63) and -2.4+/-0.7 umol/kg (n=64) for PMEL-1 and PMEL-2 respectively.

  • Alkalinity:
    1. Curve Fitting Method: Samples for total alkalinity were collected in glass bottles made from Schott Duran® glass. They were preserved by the addition of 0.02% by volume of a saturated mercury (II) chloride solution (DOE, 1994 SOP 01), and analyzed â�â�œ typically within 24 hours on board ship.
