Supplemental Information

The full method is described in Roberts, J.J., Leplastrier, A., Feitz, A., Bell, A., Karolyte, R., Shipton, Z.K. Structural controls on the location and distribution of CO2 leakage at a natural CO2 spring in Daylesford, Australia. IJGHGC. Bubble locations were determined using an Altus APS3G high precision GNSS survey system for Real Time Kinematic (RTK) position measurements. The UTM coordinates of the feature are relative to a base station at Tipperary. CO2 flux measurements were obtained using a West Systems portable flux system with attached accumulation chamber (type B) and LI-840A CO2/H2O gas analyser. A hollow 50mm PVC pipe frame was attached to the base of the accumulation chamber as a floatation device in order to facilitate flux sampling at the water surface. The base of the accumulation chamber was therefore slightly submerged in water and this change in volume was accounted for when applying the ACK (a conversion factor between ppm/sec (instrument unit) and g/m2/day). ACK temperature and pressure corrections (see Annex A) were made using meteorological measurements recorded at the nearby Ballarat Airport at 10 min intervals. The maximum bubble rate was determined using the West Systems Software (Flux Revision 3.99.4) and optimizing the flux integration for the maximum slope over 20 seconds (bubbles) and 60 seconds (background).
