Source - receptor analysis of lignin and lipid macromolecules in karst to quantify stalagmite biomarker proxies of vegetation and temperature change. Cave stalagmites are archives of past climate and environmental changes. This project seeks to develop two novel biomarkers, lignin and bacterial membrane lipids, from which we will generate new records of historic and prehistoric vegetation and temperature change.

Innovative isotopic techniques to study the response of soil and water resources to modern and past climate change: The emergence of innovative isotopic tools has provided unprecedented opportunities to improve our understanding of the processes that shape the earth's resources and environment. The plasma-source mass spectrometer will be dedicated to applying these techniques to earth surface processes, and establishing unique capabilities to decipher how soil and water resources respond to modern and past climate change in Australia.Read moreRead less
To what extent does fire affect karst processes? Burning questions for fire management. Fire management is of crucial importance for both asset protection and ecosystem management. However, the effects of fire in karst systems is poorly understood. This project will undertake experiments to determine the effects of fire on surface and subsurface processes, including stalagmite formation, that can be used to improve fire management policy.

Summary
A coupled high temperature elemental analyser - gas chromatograph - mass spectrometer for climate, water and ecological research. A coupled high temperature elemental analyser - gas chromatograph - mass spectrometer for climate, water and ecological research: This project is for a high temperature, elemental analysis, gas chromatography, isotope mass spectrometry facility. This would permit the analysis of the isotopes of up to four elements in a range of environmental samples such as tree cell ....A coupled high temperature elemental analyser - gas chromatograph - mass spectrometer for climate, water and ecological research. A coupled high temperature elemental analyser - gas chromatograph - mass spectrometer for climate, water and ecological research: This project is for a high temperature, elemental analysis, gas chromatography, isotope mass spectrometry facility. This would permit the analysis of the isotopes of up to four elements in a range of environmental samples such as tree cellulose, ecological samples and dissolved nutrients in surface and ground waters. Results will help improve our understanding of climate - surface water - ground water interactions, ecosystem function, and past climate and environmental change. The new facility will meet the need for organic isotope analyses to better understand the underlying physical processes.Read moreRead less
Landscape evolution, environmental change and human occupation history of Lake George - an outstanding natural archive. This project will study the environmental and human history of Lake George, where sand and gravel are mined to supply the Canberra region's construction industry. The project will investigate past vegetation and climate changes, lake level fluctuations, groundwater flow, sediment deposition, archaeology and sustainable resource management outcomes.
From ancient to modern environments in southeastern Australia: evidence from the unique natural archives of Lake George. Lake George is an outstanding natural archive - it contains the longest continuous sedimentary record of any Australian lake and has a long, unresolved human occupation history. It also supplies 80 per cent of sand used in the Canberra region construction industry. This multidisciplinary study aims to determine the sedimentary, vegetation, climatic, hydrological, tectonic and ....From ancient to modern environments in southeastern Australia: evidence from the unique natural archives of Lake George. Lake George is an outstanding natural archive - it contains the longest continuous sedimentary record of any Australian lake and has a long, unresolved human occupation history. It also supplies 80 per cent of sand used in the Canberra region construction industry. This multidisciplinary study aims to determine the sedimentary, vegetation, climatic, hydrological, tectonic and archaeological history of the area, including application of cutting-edge dating methods. Project outcomes aim to increase knowledge of landscape evolution and human history in eastern Australia from an improved understanding of the responses of Lake George to past and future climate change and human impact, as well as optimising sustainable extraction of sand and gravel.Read moreRead less
