The initial CO2?fluid was slightly oversaturated at the subsurface in-jectionpoint,andthustheplumewasexpectedtoinitiallydegasCO2beforeequilibratingatin-situconditions.Monitoring of carbonate system parameters in nearby observation wells helped define the evolution of theinjectedfluids,whilethenoblegastracerswereusedtoclearlydefinethephysicalbehavioroftheCO2plume(includinganestimateofdegassedCO2equalto0.9?3.1%).ThisstudydemonstratesthepotentialuseofnoblegasesformonitoringCO2leakageinshallowaquifers,constrainingmassbalanceandphasechangesofleakingfluids, and better understanding local flow pathways. Furthermore, breakthrough of noble gases in this studywas different from some previous experiments, suggestingthat monitoring efficiencyof these tracers may de-pendonleakageandsiteconditions.en_US
