| Summary: | --- Public Summary from Project --- \nThe Southern Ocean is one the most significant regions on earth for regulating the build up of anthropogenic CO2 in the atmosphere, and the capacity for carbon uptake in the region could be altered by climate change. The project aims to establish a time series of anthropogenic carbon accumulation. The work will be used to identify processes regulating the CO2 uptake and to test models that predict future uptake.\n\n2001-2002 Season:\nData collection for this project was solely carried out on voyage three of the 2001/2002 season.\n\nTotal dissolved inorganic carbon (TCO2) and titration alkalinity (TA) measurements were made on the CLIVAR SR3 section between Hobart and Antarctica. The carbon samples were taken from a 24 bottle rosette and have an approximate horizontal resolution of 60nm with closer spacing in regions where horizontal gradients were large. Many of the stations sampled for carbon had multiple casts to improve vertical resolution.\n\nThe CRM analyses were used to calibrate the titration cell volume. Preliminary analysis of Certified Reference Material (CRM) Seawater from Scripps Institution of Oceanography show data quality was generally good. For TCO2 the measurements on Batch 52 CRM's the average concentration was 2005.65 +/- 1.36 micromol/kg (n=65; 1 s.d.). For TA the average CRM values were 2224.76 +/- 1.17 micromol/kg (n=45, 1 s.d.). The certified values for Batch 52 was 2005.57 +/- 0.39 and 2224.72 +/- 0.81 micromol/kg for TCO2 and TA, respectively.\n\nThe fields in this dataset follow standard WOCE naming practices.
