Dissolved inorganic carbon, alkalinity, temperature, salinity and other variables collected from discrete sample and profile observations using Alkalinity titrator, CTD and other instruments from RRS JAMES COOK in the South Atlantic Ocean from 2009-03-07 to 2009-04-21 (NCEI Accession 0108214)

PACKAGE DESCRIPTION: This dataset includes discrete sample and profile data collected from RRS JAMES COOK in the South Atlantic Ocean from 2009-03-07 to 2009-04-21 and retrieved during cruise CLIVAR A9.5 2009 and JC032. These data include DISSOLVED INORGANIC CARBON (DIC), DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, SALINITY, TOTAL ALKALINITY (TA), WATER TEMPERATURE, phosphate and silicate. The instruments used to collect these data include Alkalinity titrator, CTD, Coulometer for DIC measurement and bottle. These data were collected by Brian A. King of National Oceanography Centre, Southampton as part of the CLIVAR_A9.5_2009 data set. The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.

VARIABLES / PARAMETERS:

Dissolved Inorganic Carbon
Abbreviation: DIC
Observation type: discrete
In-situ / Manipulation / Response variable: In-situ observation
Measured or calculated: Calculated
Detailed sampling and analyzing information: Coulometry. Two different instruments were used during JC032 for this analysis. Firstly a stand-alone DIC analyser consisting of a coulometer and a CO2 extraction unit based on the Single Operator Multiparameter Metabolic Analyzer (SOMMA), developed by Kenneth Johnson (Johnson et al., 1993; Johnson et al., 1985; Johnson et al., 1987, Johnson and Wallace, 1992), and modified at UEA (called hereafter refurbished SOMMA); and secondly a coulometer with a Versatile Instrument for the Detection of Titration Alkalinity (VINDTA), combined DIC/alkalinity instrument (version 3C, serial number #007, (Mintrop, 2004)).
CRM batch number: 90 (1985.61 +/- 0.89 μmol kg-1)
Total alkalinity
Abbreviation: TA
Observation type: discrete
In-situ / Manipulation / Response variable: In-situ observation
Measured or calculated: Measured
Curve fitting method: Ootentiometric titration with two VINDTA instruments (#004 and #007, version 3C, Mintrop, 2004).
Uncertainty: alkalinity CRM values recorded by (a) VINDTA #004 and (b) VINDTA #007, showing a whole-cruise variation of +/- 9.3 μmol kg-1 on VINDTA #004 and +/- 5.2 μmol kg-1 on VINDAT #007 after preliminary data quality control during the cruise.
