PACKAGE DESCRIPTION: This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, temperature, salinity, dissolved oxygen, nutrients and chlorofluorocarbons (CFC-11, CFC-12, CFC113) obtained during the R/V Aurora Australis cruise AA0301, CLIVAR_SR03_2001 (EXPOCODE 09AR20011029) in the Southern Ocean from 2001-10-29 to 2001-12-13. These data were collected by Bronte Tilbrook and Stephen R. Rintoul of Commonwealth Scientific and Industrial Research Organization and Christopher Sabine of US DOC; NOAA; OAR; Pacific Marine Environmental Laboratory as part of the CARINA/09AR20011029, CLIVAR_SR03_2001 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.

| Uncertainty: |
Accuracy and precision estimated to be ± 1.23 micromol/kg CRM's were used to calibrate the cell volume. Acid density was measured with an Anton Parr density meter. Acid concentrations were calibrated coulometrically. A total of 45 CRM samples were analysed for titration alkalinity during the cruise, and the standard deviation of the measurements was 1.23 micromol/kg. Duplicate samples analysed during the cruise showed an absolute difference of 0.79 ± 0.62 micromol/kg (1 s.d.; n = 151). |
