Project Description

Understanding future climate, and understanding carbon sequestration strategies, requires that we enhance our understanding of how carbon behaves in the Earth System. One area that has been comparatively overlooked is the flow of carbon through karstlands, where geologically stored carbon is released from limestone and converted into atmospheric CO2, alkalinity supplied to the ocean and into new limestone deposited as continental microbialites (“tufa”). Rough estimates of carbon fluxes in freshwater carbonate streams globally are at least 40Tg a-1, but this value is built on minimal field data and poor understanding of the processes. A critical part of the problem is that we don’t really know how carbon coming into karst rivers from soils and dissolved limestone is partitioned between gas, aqueous and sediment inventories. We aim to provide this data, by constraining the carbon fluxes occurring in a key karst river and through unique laboratory experiments. An exciting part of these experiments will be to investigate how changing the CO2 in the air above the river will change the partitioning. This means we will be able to understand how carbon flux in these rivers was different during the last glacial, and will be different as human activity continues to emit CO2.
