SOIL CO2 FLUX MONITORING EXPERIENCES FROM A LARGE-SCALE CARBON SEQUESTRATION DEMONSTRATION PROJECT
Overall, the monitoring network was successful in documenting the highly dynamic soil CO2 fluxes during the project. However, data collection and analysis were challenged by: 1) equipment malfunctions during periods of extended deployment, 2) physical disturbances to the network by local industrial activities, 3) physical damage from wildlife and weather, 4) personnel turnover, and 5) the significant investment of time and resources required to establish, maintain, and measure the network.
The IBDP experience indicates that an intensive soil flux monitoring network is not viable on a commercial scale. Further, recent leak studies at the Zero Emission Research and Technology Center, Ginninderra, and Latera Caldera suggest that surface leaks are unlikely to be detected by a point flux network. While some targeted soil CO2 flux monitoring may be useful to projects in order to establish an understanding of general soil flux conditions, soil flux monitoring may be best suited for establishing baseline information and used for field quantifications if surface leaks were present.
