Evaluating a biogeochemical mechanism for soil anomaly formation using diffusive thin-film samplers in geochemical exploration. We expect to develop new and effective technology for geochemical exploration for gold and base metals. This technology will take the form of: (i) increased understanding of, and a new conceptual model for, biogeochemical formation of soil geochemical anomalies in transported overburden; (ii) new chemical analysis techniques for soils and groundwater in mineralised area ....Evaluating a biogeochemical mechanism for soil anomaly formation using diffusive thin-film samplers in geochemical exploration. We expect to develop new and effective technology for geochemical exploration for gold and base metals. This technology will take the form of: (i) increased understanding of, and a new conceptual model for, biogeochemical formation of soil geochemical anomalies in transported overburden; (ii) new chemical analysis techniques for soils and groundwater in mineralised areas. Improved models for anomaly formation will provide a clearer frame work for exploration in terrain under transported cover. New methodology has the potential to enhance anomaly detection for buried mineralisation, especially if the anomaly has formed biogeochemically.Read moreRead less

Summary
A highly sensitive mass spectrometer for trace analysis of biomarker molecules to study changes in recent and ancient environments. Maintaining the quality of water and soil is a critically important issue for Australia's economic and social development. To be able to predict and plan the future of our natural assets, it is critical to understand their ecological past and their state before and after European settlement.

Maintaining the quality of water and soil is a critically important issue for Australia's economic and social development. To be able to predict and plan the future of our natural assets, it is critical to understand their ecological past and their state before and after European settlement. We will utilize the new instrument to develop and apply innovative technologies providing Australia with new knowledge about the causes and effects of toxic cyanobacterial blooms, eutrophication, and contamination of reservoirs by bush-fires. The new facility will also supply advanced oil fingerprinting techniques to the petroleum industry minimizing exploration risk and increasing the chance of the discovery of new oil deposits.Read moreRead less
Hyper-accumulations of monosulfidic sediments: Exploring a biogeochemical extreme to resolve fundamental sulfur biomineralisation pathways. The hyper-accumulation of monosulfidic sediments has a directsocial, economic and environmental impact on communities in many parts of Australia, including highly valued wetland systems such as the Ramsar wetlands of the lower Murray Darling Basin and internationally recognised Peel-Harvey Estuary of WA.

The hyper-accumulation of monosulfidic sediments has a directsocial, economic and environmental impact on communities in many parts of Australia, including highly valued wetland systems such as the Ramsar wetlands of the lower Murray Darling Basin and internationally recognised Peel-Harvey Estuary of WA. Maintenance dredging of these materials alone costs the nation millions of dollars annually. The hyper monosulfidic sediments are also linked to severe environmental impacts. This project will inform how these materials develop and accumulate. This new knowledge will be of immediate relevance for the management of eutrophic estuaries.Read moreRead less
Unraveling the nitrogen cycle in a periodically anoxic estuary. Climate change is likely to lead to reduced river inflows to estuaries which can lead to oxygen depletion and major changes in nutrient cycling. This project will help inform the public and policy makers about the role of environmental flows in maintaining estuarine function, and thus guide future decisions on environmental flow requirements in the Yarra River Estuary. The benefits of this understanding will also flow on to improv ....Unraveling the nitrogen cycle in a periodically anoxic estuary.

This project will help inform the public and policy makers about the role of environmental flows in maintaining estuarine function, and thus guide future decisions on environmental flow requirements in the Yarra River Estuary. The benefits of this understanding will also flow on to improved understanding and management of nitrogen loads to Port Phillip Bay. This project will form a close collaborative partnership between Monash University, Melbourne Water and the EPA. This collaboration will ensure the integration of cutting edge science with innovative management regimes Read moreRead less

SHRIMP SI - Microscale stable-isotope analysis in the Earth Sciences. 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 ....SHRIMP SI - Microscale stable-isotope analysis in the Earth Sciences. 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
Reduction of risk in exploration for petroleum liquids. Australia has an urgent need to establish additional reserves of crude oil. A feature of petroleum exploration in recent decades has been discovery of vast reserves of natural gas but an inability to replace our diminishing reserves of crude oil. Clearly new technology is required to enhance our capability to recognise crude oil-prone rather than gas-prone source rocks. The proposed project will establish the fundamental geochemical pro ....Reduction of risk in exploration for petroleum liquids. Australia has an urgent need to establish additional reserves of crude oil. A feature of petroleum exploration in recent decades has been discovery of vast reserves of natural gas but an inability to replace our diminishing reserves of crude oil. Clearly new technology is required to enhance our capability to recognise crude oil-prone rather than gas-prone source rocks. The proposed project will establish the fundamental geochemical processes that will support the potential exploration techniques, developed with Woodside Energy Limited support.Read moreRead less

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. Furthermore, this research involving Australia's major petroleum rocks will increase the ability to identify crude oil sources, to the benefit of petroleum exploration in Australia and world-wide. Importantly, this project will enable students and young professionals to be trained in state-of-the-art technologies, leading to quality scientists ready for employment in geoscience industries, and raising the profile of science careers in Australia.

Unravelling the cycling of nitrogen along a subtropical freshwater-marine continuum using a multi-isotope, multi-tracer and modelling approach. This project will significantly advance our understanding of the sources, cycling and pathways of nitrogen along a sub-tropical catchment-river-estuary. As such, the findings from this research will have direct implications to the management, rehabilitation and protection of waterways (including biodiversity) in Australia.
