Synopsis

The isotopic compositions of lake carbonate sediments can provide important information for radiocarbon dating and paleoenvironmental reconstructions. This project will use carbonate d13C and d18O, clumped (D47), and 14C compositions to better understand the carbonate isotope system in closed-basin lakes and to trace the past hydrology and temperature evolution over the Last Glacial/Holocene transition (approximately 12,000 years ago). This will integrate three isotopic methods and radiocarbon dating using the CHRONOS facility for the first time. The project will be undertaken in our state-of-the-art laboratory [interactive tour], in collaboration with Macquarie University and the Thermo Fisher 253+ Clumped Isotope mass spectrometer.

Aims

Produce a climate reconstruction using lake carbonate sediments.

Student benefits

Through this project, you will learn how to design and carry out experiments, analyse and interpret data, and how to write a scientific paper. You will also have the opportunity to learn each step of the radiocarbon process, including sampling, pretreating and graphitisation. You will also be integrated within the CHRONOS 14Carbon-Cycle Facility as well as the Earth and Sustainability Science Research Centre, with opportunities for training and career development.
