How warm and how wet? New perspectives on paleoclimate records and hydrological regimes in arid zones of Australia. This project will develop a new and precise palaeotemperature record for southern Australia, and will investigate the hydrologic dynamics of inland Australia. Together, this research will lead to new discoveries in the way Australian ecosystems respond to climate variability and will enable better understanding of its impacts.
Deep-sea coral ocean-climate records of the last glacial and recent eras. The project aims to predict the ocean carbon dioxide sink’s long-term capacity and future trajectories of global warming and increasing carbon dioxide. This project will use geochemical proxies encoded in the skeletons of deep-sea corals in the Perth Canyon, Tasman seas, and Antarctica, in the heart of the ocean-climate system, to reveal continuous long-term records of environmental change at annual-decadal resolution for ....Deep-sea coral ocean-climate records of the last glacial and recent eras. The project aims to predict the ocean carbon dioxide sink’s long-term capacity and future trajectories of global warming and increasing carbon dioxide. This project will use geochemical proxies encoded in the skeletons of deep-sea corals in the Perth Canyon, Tasman seas, and Antarctica, in the heart of the ocean-climate system, to reveal continuous long-term records of environmental change at annual-decadal resolution for our recent past (hundreds to thousands of years) and the Last Glacial Maximum. These records are expected to provide a more accurate understanding of Earth’s long-term responses to anthropogenic carbon dioxide emissions and global warming.Read moreRead less
Chemostat experiments to mimic toxic environments associated with mass extinction events. This project will help scientists understand past climate changes and understand the mechanisms of global warming. This in turn will improve our ability to forecast future climate change, and help Australia manage current threats to its biodiversity. Importantly, this project will enable students and young professionals to be trained in state-of-the-art technologies, leading to quality scientists ready for ....Chemostat experiments to mimic toxic environments associated with mass extinction events.

Unravelling how aquatic coastal networks regulate nitrogen removal . The aim of this project is to determine the nitrogen removal pathways of the coastal zone using a number of innovative field and modelling approaches. Little is known about how the complex coastal landscape controls trade-offs that maximise nitrogen removal but minimise nitrous oxide (a potent greenhouse gas) emissions. The outcomes of this study will significantly advance our understanding of the coastal zone in regional and g ....Unravelling how aquatic coastal networks regulate nitrogen removal . The aim of this project is to determine the nitrogen removal pathways of the coastal zone using a number of innovative field and modelling approaches. Little is known about how the complex coastal landscape controls trade-offs that maximise nitrogen removal but minimise nitrous oxide (a potent greenhouse gas) emissions. The outcomes of this study will significantly advance our understanding of the coastal zone in regional and global nitrogen budgets. This will provide significant benefits such as a new science-based quantitative framework to facilitate best practice management to reduce terrestrial nitrogen loads and associated downstream impacts such as eutrophication, and reduce nitrous oxide emissions and associated global warming.

Summary
A new paradigm for quantifying the resilience of marine calcifiers to ocean acidification and global warming. This multi-disciplinary research project will determine the future of coral reefs and marine calcifiers in response to rising carbon dioxide and ocean acidification. This will enable best-practice adaptive management at local and regional-scales for marine-dependent industries, and provide new hope for some of our greatest natural assets, coral reefs.
Aqueous fluids in the deep earth. This project aims to improve our understanding of the role of fluids in controlling exchanges between the deep Earth, shallow rocks, and atmosphere. The project expects to investigate some of the key weaknesses in the thermodynamic models that are used to predict the behaviour of sulphur, carbon and metals in fluids at high pressure and temperature by using recent advances in computational and experimental (geo)chemistry. Integrated in large-scale geodynamic mod ....Aqueous fluids in the deep earth. This project aims to improve our understanding of the role of fluids in controlling exchanges between the deep Earth, shallow rocks, and atmosphere. The project expects to investigate some of the key weaknesses in the thermodynamic models that are used to predict the behaviour of sulphur, carbon and metals in fluids at high pressure and temperature by using recent advances in computational and experimental (geo)chemistry. Integrated in large-scale geodynamic models, the more reliable predictions will provide a more realistic assessment of the role of sulphur in controlling metal endowment and atmospheric chemistry through geological times. This should provide a useful guide for mineral exploration and planetary science.Read moreRead less
The Impact of Changing Climatic Conditions inferred from the Isotope Abundances of Trace Metals in Global Ice Sheets and Glaciers. In this project Greenland and Antarctic ice-cores more than 3 km long will be used to investigate climatic variation extending back more that 4 complete glacial cycles. Some of these ice-cores include sections of refrozen water formed from sub-glacial Antarctic lake water. This project will use naturally occurring lead and strontium isotopic tracers to fingerprint ....The Impact of Changing Climatic Conditions inferred from the Isotope Abundances of Trace Metals in Global Ice Sheets and Glaciers. In this project Greenland and Antarctic ice-cores more than 3 km long will be used to investigate climatic variation extending back more that 4 complete glacial cycles. Some of these ice-cores include sections of refrozen water formed from sub-glacial Antarctic lake water. This project will use naturally occurring lead and strontium isotopic tracers to fingerprint impurities in the ice, because they have the potential to simultaneously signal the timing and location of past episodes of climate change. This will lead to an improvement in our understanding of the processes that cause these changes.Read moreRead less

Stable-isotope variations of elements such as oxygen, carbon, and sulphur, preserve the most profound records of environmental conditions during the geological, biological, and climatic evolution of Earth and planets. We will build a stable isotope ion microprobe (SHRIMP SI) to examine extraterrestrial and terrestrial systems in unprecedented detail. In terrestrial applications, the main issue is accuracy at the 0.01 percent level for 20-micron spots, which we can apply to studies of development of life on Earth, climatic records, weathering, and formation of ore bodies. Sample return missions of solar wind and comets will provide unique samples related to the formation of our solar system.Read moreRead less
