Exposure dating with manganese-53, neon-21 and beryllium-10: a new toolkit for studying long-term landscape evolution. Australia today is the driest inhabited continent but this was not always the case. Tens of millions of years ago the climate of Australia was considerably wetter. Then, several million years ago, aridity in Australia developed producing most of the desert features of the red Centre that we see today. The age of our deserts and other arid features are not, however, well known.

Australia today is the driest inhabited continent but this was not always the case. Tens of millions of years ago the climate of Australia was considerably wetter. Then, several million years ago, aridity in Australia developed producing most of the desert features of the red Centre that we see today. The age of our deserts and other arid features are not, however, well known. This project will determine the age of desertification in Australia, thereby enhancing our understanding of such processes and the response of our landscape to changing climate.

Testing the Australian Megatsunami Hypothesis. More than 300000 lives and property worth more than $150bn on the NSW coast are vulnerable to large tsunamis but at present we do not have a clear idea about how often such tsunamis occur and how big they might be. This project will identify and date evidence for past tsunamis on the coasts of NSW and west New Zealand which will help us understand regional tsunami risk. This will provide knowledge that will guide tsunami risk management practice in ....Testing the Australian Megatsunami Hypothesis.

This project will identify and date evidence for past tsunamis on the coasts of NSW and west New Zealand which will help us understand regional tsunami risk. This will provide knowledge that will guide tsunami risk management practice in vulnerable areas of NSW and help underpin the developing Australian Tsunami Warning System. Read moreRead less
Landscape evolution and palaeoclimates in Indonesia: environmental, faunal and archaeological implications. The influence of environmental and climatic changes on faunal (including human) populations is a pressing issue for Australian communities in environmentally sensitive areas. This project will address this issue by documenting how certain flora and fauna in Indonesia, our nearest northern neighbour, responded to environmental challenges. Revealing when humans first dispersed through the re ....Landscape evolution and palaeoclimates in Indonesia: environmental, faunal and archaeological implications. The influence of environmental and climatic changes on faunal (including human) populations is a pressing issue for Australian communities in environmentally sensitive areas. This project will address this issue by documenting how certain flora and fauna in Indonesia, our nearest northern neighbour, responded to environmental challenges. Revealing when humans first dispersed through the region and how they adapted to changing environmental conditions will also contribute to our understanding of the cultural heritage of Australia's indigenous settlers. This project will build on established collaborations with Indonesian researchers and pioneer new dating methodologies to further enhance Australia's place at the forefront of geochronology.Read moreRead less
