These data were collected by Frank J. Millero of Rosenstiel School of Marine and Atmospheric Science, Rik Wanninkhof of NOAA Atlantic Oceanographic and Meteorological Laboratory and Richard A. Feely of US DOC; NOAA; OAR; Pacific Marine Environmental Laboratory as part of the CLIVAR_A16S_2005 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.

Type of titration: |
The method utilizes a multi-point hydrochloric acid titration of seawater according to the definition of total alkalinity (Dickson, 1981). |
Cell type (open or closed): |
Closed |
Curve fitting method: |
The titration system used consists of a Metrohm 665 Dosimat titrator, an Orion 720A pH meter and a custom designed plastic water-jacketed titration cell (Millero et al., 1993b). |
Uncertainty: |
CRM: Standard Deviation: ± 3.5 µmol/kg Duplicates: Instrument 1: ± 1.6 µmol/kg Instrument 2: ± 1.3 µmol/kg Between Systems: ± 2.9 µmol/kg |

pH |
Abbreviation: |
pH |
pH scale: |
Sea Water Scale (SWS) |
Observation type: |
discrete |

In-situ observation |
Measured or calculated: |
Measured |
Temperature of pH measurement: |
25C |
Detailed sampling and analyzing information: |
Measurements of the pH of seawater on the total hydrogen ion concentration pH scale (pHt) were made using the multi-wavelength spectrophotometric techniques of Clayton and Byrne (1993). |
Uncertainty: |
A precision of better than 0.001. Batch #59: pHsws @ 25C 7.9048 +/- 0.0007 (n = 19) |
pCO2 (fCO2) discrete |
Abbreviation: |
fCO2 |
Observation type: |
discrete |
In-situ / Manipulation / Response variable: |
In-situ observation |
Measured or calculated: |
Measured |
Storage method: |
Poisoned with 0.3 ml HgCl2 and stored upside down in coolers up to 12-hours |

Detailed sampling and analyzing information: |
Headspace analysis using a LICOR infrared analyzer |
Sample replicate information: |
0.2+/- 0.2% or 2.3 +/- 1.5 ppm (n=90) |
Temperature correction method: |
waterbath was always within 0.03 C from 20 C. The small correction to 20 C was done by dpCO2/dt = 0.0423 |
Uncertainty: |
Internal consistency calculations with DIC and TAlk showed TAlk-measured-Talk(DIC,fCO2) of -2 and a st dev of 4.1 μmol/kg (n=768). If error is distributed evely between all parameters the fCO2 accuracy would be about 3 uatm. |
