Brief description

The CSIRO archive of observed atmospheric CO2 concentrations at the Otway Basin Naylor Field (30km WNW of Peterborough) carbon-dioxide geo-sequestration site, measured with the CSIRO developed LOFLO Mk2 instrument. This study (the first of its kind in Australia) by the Cooperative Research Center for Greenhouse Gas Technologies (CO2CRC) is to monitor the trial geo-sequestration of CO2 into the depleted gas field (Naylor Field) and to observe the environmental effects to determine the viability and effectiveness of CO2 geo-sequestration. LOFLO is an analysis system built around a commercial LI-COR 6251 optical bench which utilizes NDIR (non-dispersive infrared) gas analysis technology to measure CO2 concentrations in sample air. Consuming smaller volumes of calibration gases (approx. 15ml/min) and requiring much less operator intervention, LOFLO measurements have significantly less bias than traditional NDIR measurement techniques.Measurements using LOFLO first began at Cape Grim in May 2000 and has since been expanded to other global stations with the newer improved LOFLO Mk2.
