We propose a truly innovative project to address head on the problem of determining GVFCO2. We will create new, compact instruments, utilising cutting-edge laser technologies, which will allow us to measure volcanic CO2, H2O, SO2 and HCl fluxes from aircraft. By flying below and through the volcanic plumes created by ~50 active volcanoes (~10% of all active volcanoes) of the Banda-Sunda arc in Indonesia, the majority of which have never been measured before, we will dramatically increase our understanding of GVFCO2 and geochemical cycles for all these species.
Measuring the volcanic emissions from an entire subduction arc is an unprecedented experiment, providing insight into the slab and mantle heterogeneity and volatile mass balance. Perhaps the most important breakthrough that we will pursue will be the determination of the 37Cl/35Cl ratio from HCl emitted from each volcano. This ratio reflects the mantle/slab source proportion, and allows the input rate of volatiles to the mantle to be measured.
The application of innovative new technology we propose here will produce ground-breaking insights into volcanology, isotope and gas geochemistry, volatile cycles, subduction and climate change.
