Blyth, Alison - Curtin University - Department of Chemistry

研究领域

Alison's research spans several disciplinary areas, including chemistry, geology, environmental science, physical geography, palaeontology, ecology and archaeology, with the common aim of applying chemical techniques to gaining a better understanding of how climate and the environment function. Research projects include: The use of biomarkers and stable isotopes in cave sediments and speleothems to identify past changes in climate and the associated environmental response. The use of compound specific isotopes to identify ecosystem interactions such as carbon source or trophic level, and their response to environmental peturbations. Low abundance radiocarbon dating to resolve the timing of different source inputs to terrestrial palaeo-records. The development of new ways to measure isotopes in mammalian fossils, particularly micro-mammals.
