Summary
Accelerated solvent extractor and evaporator for molecular and stable isotope analyses of sedimentary organic matter. The accelerated solvent extractor (ASE) uses pressurised liquid extraction to obtain the bitumen fraction easily measurable for molecular and isotopic composition of organic sediments in just a few minutes. This compares favourably to traditional extraction procedures, which can take two to three days. Our projects often require the analyses of large numbers of sediment extracts ....Accelerated solvent extractor and evaporator for molecular and stable isotope analyses of sedimentary organic matter. The accelerated solvent extractor (ASE) uses pressurised liquid extraction to obtain the bitumen fraction easily measurable for molecular and isotopic composition of organic sediments in just a few minutes. This compares favourably to traditional extraction procedures, which can take two to three days. Our projects often require the analyses of large numbers of sediment extracts to obtain chemical data at high geological resolution. The ASE/Evaporator will greatly assist these endeavours which aim to improve our understanding of Australian environments (incorporating the effects of natural and human-related processes) and identify source rocks offering good petroleum reserves.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.

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.Read moreRead less
Characteristics of organic matter formed in toxic, sulfide-rich modern and ancient environments. 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 petrol ....Characteristics of organic matter formed in toxic, sulfide-rich modern and ancient environments.

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.

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

Summary
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
