This dataset includes discrete bottle measurements of dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, partial pressure of CO2, dissolved organic carbon (DOC), CFCs, temperature, salinity, oxygen, nutrients, and other variables measured during R/V N.B. Palmer cruise in the South Pacific Ocean on GO-SHIP/CLIVAR/SOCCOM Repeat Hydrography Sections P06W (EXPOCODE 320620170703) and P06E (EXPOCODE 320620170820) from 2017-07-03 to 2017-09-30. The Pacific Ocean P06 repeat hydrographic line was reoccupied for the US Global Ocean Carbon and Repeat Hydrography Program. Reoccupation of the P06E transect occurred on the RVIB Nathaniel B Palmer from August 20, 2017 to September 30, 2017. The survey of P06 2017 consisted of CTDO, rosette, LADCP, chipod, water samples and underway measurements. The ship departed from the port of Papeete on the island of Tahiti, French Polynesia and completed the cruise in the port of Valparaiso, Chile.

Processing Steps
  • Parameter or Variable: Dissolved Inorganic Carbon; Abbreviation: TCARBN; Unit: UMOL/KG; Observation type: Discrete, bottle; Measured or calculated: Measured; Sampling instrument: CDT Bottles; Analyzing instrument: Coulometric measurement system (SOMMA); Detailed sampling and analyzing information: The analysis was done by coulometry with two analytical systems (PMEL 1 and PMEL2) used simultaneously on the cruise. Each system consisted of a coulometer (CM5015-O UIC Inc) coupled with a Dissolved Inorganic Carbon Extractor (DICE). DICE system was developed by Esa Peltola and Denis Pierrot of NOAA/AOML and Dana Greeley of NOAA/PMEL to modernize a carbon extractor called SOMMA ([Johnson1985], [Johnson1987], [Johnson1993], [Johnson1992], [Johnson1999]).; Standardization description: Injection of 2 pairs of sample loops of known volume of pure CO2 bracketing the expected values of TCO2 and analysis of Certified Reference Materials supplied by Dr. A Dickson of SIO. TCO2 values were corrected for the addition of mercuric chloride and for the offset from the CRM value.; CRM manufacturer: Andrew Dickson Laboratory at SIO; CRM batch number: B165, B166; Preservation method: mercuric chloride solution; Preservative volume: 100 mL; Uncertainty: The accuracy of the DICE measurement is determined with the use of standards (Certified Reference Materials (CRMs), consisting of filtered and UV irradiated seawater) supplied by Dr. A. Dickson of Scripps Institution of Oceanography (SIO). The CRM accuracy is determined manometrically on land in San Diego and the DIC data re- ported to the data base have been corrected to this batch 165 CRM value. The CRM certified value for this batch is 2064.33 μmol/kg.; Quality flag convention: WOCE quality control flags are used: 2 = good value, 3 = questionable value, 4 = bad value; Method reference: Johnson, K., Wills, K., Butler, D., Johnson, W., and Wong, C.: Coulometric total carbon dioxide analysis for marine studies: maximizing the performance of an automated gas extraction system and coulometric detector, Mar.
