Biogeochemical drivers of uranium isotope fractionation in regolith and groundwater. Water and soil resources are critical to Australia's present and future health and wealth. This project provides necessary data to increase our understanding groundwater recharge, flow and quality, weathering rates and uranium behaviour in soil and water. It will help delineate the impacts of agricultural activities and climate change. It may also trigger the development of new mineral exploration strategies for ....Biogeochemical drivers of uranium isotope fractionation in regolith and groundwater.

Summary
A stable-isotope mass spectrometer for novel determinations of past temperatures. Much of the Australian landscape is subject to a dry and evaporative climate, making it very difficult to use conventional geochemical techniques to estimate past temperatures, even on short timescales of tens to hundreds of years. The application of a new isotopic technique to preserved carbonate minerals (soil carbonate, shells in rivers, lakes and the ocean) avoids the difficulty of this variable evaporation, an ....A stable-isotope mass spectrometer for novel determinations of past temperatures. Much of the Australian landscape is subject to a dry and evaporative climate, making it very difficult to use conventional geochemical techniques to estimate past temperatures, even on short timescales of tens to hundreds of years. The application of a new isotopic technique to preserved carbonate minerals (soil carbonate, shells in rivers, lakes and the ocean) avoids the difficulty of this variable evaporation, and directly measures past temperatures. This will have a profound effect on our understanding of environmental changes on both short and long time scales, and permit a better understanding of the hydrological balances within the landscape.Read moreRead less

Summary
Mobile Australian field isotope alliance. This project will enable a quantum leap in capacity to undertake, real-time, field-based studies of environmental processes using the natural isotope tracers of carbon, oxygen and hydrogen. This will enable the project to address a range of fundamental research questions in climate change, water resources, ecology and human impact in tropical Australia.
