Data products to quantify the variability and long-term trends in biogeochemical properties (e.g. carbon, oxygen, nutrients) from around Australia and the Southern Ocean. Detection of ocean acidification and the quantification of the processes driving change across coastal-shelf-offshore scales and ranging form tropical to high latitude shelf systems. Determinations of the role of the current systems around Australia (i.e. East Australian Current, Leeuwin Current, Antarctic Circumpolar Current) in controlling carbon uptake and the potential for change. Improved understanding of controls on productivity and biological carbon export from the surface ocean, and the sensitivity to changing environmental conditions. Quantification of the role of Australian regional seas and the Southern Ocean in the uptake and storage of anthropogenic CO2, and the processes driving shifts in the uptake efficiency that may alter the global carbon budget and our future climate. Assessments of the role of the Southern Ocean in oxygenating the and supplying nutrients to support primary production in tropical and subtropical regions. Improved understanding of coast-offshore interaction and the role of shelf processes and feedbacks in influencing biogeochemical cycles. A biogeochemical modelling system working across multiple domains (coastal, reef, shelf, offshore, atmosphere and land) for a range of time and space scales to diagnose controls on biogeochemical cycling and predict future change. Improved projections by employing better models guided by new process understanding and observations Better assessment of the risk of ocean acidification to ecosystem services and marine ecosystems A system to examine and test mitigation options to reduce future impacts of climate change and acidification on marine systems.
