CCS - MV Bluefin 2017 V01 TCO2 and TA

Full description

Project Overview: A range of solutions will be required to reach globally agreed emissions reductions targets for carbon dioxide (CO2). Carbon capture and storage (CCS) is part of the suite of technologies that will contribute to lowering atmospheric emissions of CO2 from Australia's energy system. There are a wide variety of technologies at various stages of technical and commercial readiness, with more development underway for cost effective CO2 capture and storage. Our research will provide new knowledge to inform cost-efficient measurement, monitoring and verification (MMV) of the environment of CCS projects in coastal waters.

Total carbon dioxide (TCO2) and total alkalinity (TA) measurements on seawater samples from CTD and underway samples. Samples analysed in Hobart after voyage.

Calibration Information:

TCO2 Standard deviation of 6 replicate certified reference materials (CRMs) was 1.52 µmol/kg The average value of these 6 measurements was 2070.35 µmol/kg compared to the certified value of 2071.47 µmol/kg. Data were corrected for the difference from the certified CRM value of the daily average of CRMs run at the beginning and end of the day.

TA The standard deviation of 9 replicate CRMs measurements was 0.84 µmol/kg.
The average value of the 0 measurements was 2196.19 µmol/kg compared to the certified value of 2207.64 µmol/kg. All data were corrected by multiplying by 1.005214, being the certified value divided by the average value.
