    Geoscience Australia and the CO 2 CRC operate a greenhouse gas controlled release facility at an experimental agricultural station maintained by CSIRO Plant Industry in Canberra, Australia. The facility is designed to simulate surface emissions of CO 2 and other greenhouse gases from the soil into the atmosphere. Over 10 different near surface monitoring tcchniqucs were trial led at the Ginninderra controlled release site during 2012-2013. These included soil gas, soil CO 2 flux, soil analysis, eddy covariancc, CO 2 laser, noble gas traccrs, airborne hyperspectral, in-field phenotyping (thermal, hyperspectral and 3D imaging), and microbial soil genomics. Result highlights arc presented. Different climatic conditions for the early 2012 release experiment (wet) and late 2013 release experiment (dry) resulted in markedly different sub-surface plume behaviour and surfacc expression of CO 2 . The differences between the years arc attributed to changes in groundwater levels and drier conditions leading to a larger vadose zone during the 2013 experiment.
