Method Description:
  • Total C02 Data:
    1. TCO2 Analysis Method: The DIC analytical equipment was set up in a seagoing container modified for use as a shipboard laboratory. The 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 (Single Operator Multiparameter Metabolic Analyzer) inlet system developed by Ken Johnson (Johnson et al., 1985,1987,1993; Johnson, 1992)
    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. The instruments were calibrated at the beginning, middle, and end of each station with a set of the gas loop injections.
      2. Sample Volume: 500-mL
      3. CRM Info:
        1. Correction Magnitude: NA
        2. Batch Number: Batch 65
        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 combined was 0.7+/-1.4 umol/kg respectively (n=154).
    3. Field Replicate Info: Over 2700 samples were analyzed for DIC; full profiles were completed at even numbered stations, with replicate samples taken from the surface, oxygen minimum, and bottom Niskin-type bottles. On the odd numbered stations, samples were drawn throughout the upper 1200m; on three occasions were only surface replicates drawn due to equipment problems, resulting in a backlog of samples. All replicate samples were run at different times during the station analysis for quality assurance of the integrity of the coulometer cell solutions. No systematic differences between the replicates were observed. In addition, samples were drawn from the underway seawater system, generally one to two times daily.

    5. Accuracy Info: The overall accuracy and precision for the CRMs on both instruments combined was 0.7+/-1.4 umol/kg respectively (n=154).
