14CHRONOS (Chronologies from High-ResolutiON Organic Separations): a centre for radiocarbon dating of specific compounds for the environmental and archaeological sciences. Accurate timekeeping is central to the environmental and archaeological sciences. Radiocarbon dating is the leading geochronological technique for events of the past 50,000 years, but the issue for sample contamination remains a major source of concern.

Accurate timekeeping is central to the environmental and archaeological sciences. Radiocarbon dating is the leading geochronological technique for events of the past 50,000 years, but the issue for sample contamination remains a major source of concern. Avoidance of contaminants can be achieved through the identification of specific biomolecular compounds that unambiguously formed part of the original sample, and the isolation of these biomolecules for radiocarbon dating using accelerator mass spectrometry. Here we request funds to establish Australia's first compound-specific radiocarbon dating facility, to obtain ages of high accuracy for key studies of climate and landscape change, evolutionary biology and archaeology.Read moreRead less
Non-CO2 greenhouse gas emissions in afforested ecosystems in southeastern Australia - fluxes, processes and regional budget. There are no data available about the extent of emissions of the non-CO2 greenhouse gases nitrous oxide and methane from soils of forest ecosystems in Australia and the current methodolgy to quantify these emissions contains high uncertainties. Using the latest technology available we propose to i) measure emission rates of afforested ecosystems for non-CO2 greenhouse gase ....Non-CO2 greenhouse gas emissions in afforested ecosystems in southeastern Australia - fluxes, processes and regional budget. There are no data available about the extent of emissions of the non-CO2 greenhouse gases nitrous oxide and methane from soils of forest ecosystems in Australia and the current methodolgy to quantify these emissions contains high uncertainties. Using the latest technology available we propose to i) measure emission rates of afforested ecosystems for non-CO2 greenhouse gases in relation to previous land-use in southeastern Australia, ii) identify the processes controlling the emissions, iii) use the obtained data to calibrate a biogeochemical model, and iv) use the model to estimate regional inventories for non-CO2 greenhouse gas emissions in southeastern Australia.Read moreRead less

Summary
A high-resolution isotope facility for low cost analysis of water, plant, and soil/sediment samples to understand environmental change. The most significant environmental challenges facing Australia include ensuring sustainable management of our water resources and conservation of both terrestrial and marine biodiversity, particularly in the face of our changing climate and land-use.

The most significant environmental challenges facing Australia include ensuring sustainable management of our water resources and conservation of both terrestrial and marine biodiversity, particularly in the face of our changing climate and land-use. The new instruments will accelerate progress across a number of projects aimed at understanding the development of groundwater resources, the relative dependency of ecosystems on groundwater versus soil and surface water, and an assessment of the likely impacts of altered hydrology, especially dewatering and salinisation, on ecosystems. In addition, they will also be used to extend our knowledge of climate variability in the recent past and increase understanding of critical marine resources.Read moreRead less
