PACKAGE DESCRIPTION: This dataset includes discrete sample and profile data collected during the R/V Roger Revelle cruise along CLIVAR Repeat Section I06S (EXPOCODE 33RR20080204) in the Indian and Southern Oceans from 2008-02-04 to 2008-03-17. These data include the measurements of dissolved inorganic carbon (DIC), total alkalinity, pH on seawater scale, CTD temperature, salinity, dissolved oxygen, nutrients, chlorofluorocarbons (CFC-11, CFC-12, CFC113), tritium, tritier, neon, helium, delta C13, delta C14, and delta O18. These data were collected by Rik Wanninkhof of NOAA Atlantic Oceanographic and Meteorological Laboratory, Andrew Dickson of University of California - San Diego; Scripps Institution of Oceanography and Craig A. Carlson of University of California - Santa Barbara as part of the CLIVAR_I06S_2008 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.
CITE AS: Wanninkhof, Rik; Dickson, Andrew G.; Carlson, Craig A. (2013). Dissolved inorganic carbon (DIC), pH on seawater scale, total alkalinity, partial pressure of carbon dioxide (pCO2), temperature, salinity and other variables collected from discrete samples and profile observations during the R/V Roger Revelle cruise along the CLIVAR Repeat Section I06S (EXPOCODE 33RR20080204) in the Indian and Southern Oceans from 2008-02-04 to 2008-03-17 (NCEI Accession 0108118).

| In-situ / Manipulation / Response variable: |

| In-situ / Manipulation / Response variable: |

| Measured or calculated: |
Measured |
| Type of titration: |
potentiometric |
| Cell type (open or closed): |
Open |
| Curve fitting method: |
The total alkalinity analyses performed during I6S, were performed using a two-stage, potentiometric, opencell titration and coulometrically analyzed hydrochloric acid. |
| Uncertainty: |
Preliminary data indicate that the samples are approximately 2 units higher than the certified alkalinity value for Batch 86. After rejecting 6 of 166 CRM runs, the standard deviation was about 1 umole/kg-sol. The duplicates typically agreed within 0 to 2 umoles/kg of each other, with most of the duplicates within 1 umole/kg of the first run. |

| Abbreviation: |

| pH scale: |
Seawater scale |
| Observation type: |
discrete |
| In-situ / Manipulation / Response variable: |
In-situ observation |
| Measured or calculated: |

| Temperature of pH measurement: |
20 |
| Detailed sampling and analyzing information: |
Measurements were made using a modified version of the procedure described in Clayton and Byrne 1993 with spectrophotometric measurements of pH-sensitive m-cresol purple dye added to seawater. Measurements were made relative to 20C for stations numbered 1-24, and at 13C for all subsequent stations. |
| Uncertainty: |
For stations 25-73, the precision is estimated to be 0.001. For all remaining stations the precision is estimated at 0.0005 |
