Processing Steps
  • Parameter or Variable: Dissolved Inorganic Carbon; Abbreviation: DIC; Observation type: discrete; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Calculated; Replicate information: Greater than 10% of these samples were taken as replicates as a check of our precision. These replicate samples were typically taken from the surface, oxygen minimum, and bottom bottles. The replicate samples were interspersed throughout the station analysis for quality assurance and integrity of the coulometer cell solutions and no systematic differences between the replicates were observed. The absolute average difference from the mean of these replicates is 0.8 μmol/kg.; Standardization description: Secondary standards were run throughout the cruise (at least one per station) 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). Their accuracy is determined manometrically on land in San Diego. DIC data reported to the database have been corrected to the batch 117 CRM value. The reported CRM value for this batch is 2009.99 μmol/kg. The average measured values (in μmol/kg during this cruise) were 2010.36 for PMEL-1 and 2010.47 for PMEL-2.; CRM batch number: Batch 117.
