PACKAGE DESCRIPTION: This dataset includes discrete sample and profile data collected from MELVILLE in the South Pacific Ocean and Tasman Sea from 2009-11-21 to 2010-02-11 and retrieved during cruise CLIVAR_P06_2009. These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-113 (CFC-113), CHLOROFLUOROCARBON-12 (CFC-12), DELTA CARBON-13, DELTA CARBON-14, DELTA HELIUM-3, DISSOLVED INORGANIC CARBON (DIC), DISSOLVED ORGANIC CARBON, DISSOLVED OXYGEN, HELIUM, HYDROSTATIC PRESSURE, NEON, NITRATE, NITRITE, Potential temperature (theta), SALINITY, SULFUR HEXAFLUORIDE (SF6), TOTAL ALKALINITY (TA), Tritium (Hydrogen isotope), WATER TEMPERATURE, pH, phosphate and silicate. The instruments used to collect these data include Alkalinity titrator, CTD, Coulometer for DIC measurement, bottle and spectrophotometer.
These data were collected by Robert M. Key of Princeton University; Department of Geosciences; Program in Atmospheric and Ocean Sciences, Frank J. Millero of Rosenstiel School of Marine and Atmospheric Science, Rik Wanninkhof of NOAA Atlantic Oceanographic and Meteorological Laboratory and Craig A. Carlson of University of California - Santa Barbara as part of the CLIVAR_P06_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.

Observation type: |
discrete |
In-situ / Manipulation / Response variable: |
In-situ observation |
Measured or calculated: |
Calculated |
Detailed sampling and analyzing information: |
Acid Extraction with displacement of CO2 into a coulometer. Two coulometer were used AOML#3 and AOML#4 |
Standardization description: |
Modified SOMMA called DICE (pumped acid, pletier cwater trap) |

Observation type: |
discrete |
In-situ / Manipulation / Response variable: |
In-situ observation |
Measured or calculated: |
Measured |
Type of titration: |
Potentiometric titrations of seawater |
Cell type (open or closed): |
The water-jacketed cell is similar to the cells used by Bradshaw and Brewer (1988) |
Curve fitting method: |
Multi-point hydrochloric acid titration of seawater. Titration systems consist of a Metrohm 665 Dosimat titrator, an Orion 720A pH meter and a custom designed plexiglass water-jacketed titration cell |
Uncertainty: |
Calibrations of the burette of the Dosimat with water at 25C indicate that the systems deliver 3.000 ml (the approximate value for a titration of 200 ml of seawater) to a precision of +/- 0.0004 ml, resulting in an error of +/- 0.3 μmol/kg in TAlk. |
