Continental shelf waters connecting terrestrial with oceanic systems are acknowledged to be major, but under investigated, components of the global carbon cycle. Long term sequestration of terrestrial and marine carbon requires that carbon travels across the shelf, sinks into the deep ocean, and/or is buried in sediments. Given the importance of shelf waters for fisheries and other ecosystem services, and their lack of representation in global models, it is crucial to understand and quantify the factors regulating shelf carbon fluxes and how they affect the global carbon budget. The Barefoot team is working on constraining the fate and fluxes of carbon on the continental shelf in northern NSW and in the Great Barrier Reef using a combination of radioactive tracers and carbon observations.
