Summary
Rapid climate change, early modern human dispersal, and Neanderthal demise. Why are we the only surviving human species? This project aims to investigate whether seasonal environmental changes associated with rapid climate change events played a role in the expansion of our own species and the demise of Neanderthals between 60,000-30,000 years ago. The project will generate quantitative, sub-seasonal records of past climate variability using novel multi-proxy analyses from key archaeological sit ....Rapid climate change, early modern human dispersal, and Neanderthal demise. Why are we the only surviving human species? This project aims to investigate whether seasonal environmental changes associated with rapid climate change events played a role in the expansion of our own species and the demise of Neanderthals between 60,000-30,000 years ago. The project will generate quantitative, sub-seasonal records of past climate variability using novel multi-proxy analyses from key archaeological sites, offering a framework for understanding early human responses to extreme climate fluctuations. This may inform our strategies for coping with future extreme scenarios. These unparalleled records will also provide data to test and refine climate models, enabling a better understanding of Earth’s climate system. Read moreRead less
Single-sample unmixing with machine learning: a rock magnetic frontier. Magnetic rock-forming minerals can record important information about Earth’s magnetic field and climatic changes. In rock magnetism, we seek to quantify magnetic property variations in geological materials. Existing quantification methods are limited and provide bulk characterisation of all magnetic particles in a material rather than diagnostic information concerning individual mineral components. This Project aims to deve ....Single-sample unmixing with machine learning: a rock magnetic frontier. Magnetic rock-forming minerals can record important information about Earth’s magnetic field and climatic changes. In rock magnetism, we seek to quantify magnetic property variations in geological materials. Existing quantification methods are limited and provide bulk characterisation of all magnetic particles in a material rather than diagnostic information concerning individual mineral components. This Project aims to develop a machine-learning framework to “unmix” and quantify each magnetic mineral component in single natural samples, and will unlock a new quantitative era in rock magnetism. It is expected to have impact beyond Earth science by enabling magnetic characterisation in physics, materials science, and industry.Read moreRead less
The mighty ape’s last stand. This project aims to study the fate of primates in southern Asia, where evidence for megafaunal extinction is rare. Why Gigantopithecus blacki, the largest ever primate, disappeared is unknown, while humans in the region survived. This project will model dating techniques across sites to identify a precise extinction window and compare behaviour and past environmental conditions to determine why the ape failed and man persevered. Outcomes will generate a new understa ....The mighty ape’s last stand. This project aims to study the fate of primates in southern Asia, where evidence for megafaunal extinction is rare.

This project will model dating techniques across sites to identify a precise extinction window and compare behaviour and past environmental conditions to determine why the ape failed and man persevered. Outcomes will generate a new understanding of past environmental change as a driver of megafaunal extinction in comparison with human adaption and survival.Read moreRead less

This project aims to provide critical new information on the archaeology and natural history of one of the world’s largest unregulated desert river systems. Mithaka country incorporates the highly significant Channel Country on the eastern edge of Australia's arid centre. Preliminary research has identified more than 70 large site complexes that provide critical insights on how the Mithaka people adapted to this unique environment and took part in Australia's most extensive long distance trade systems. The project will study the archaeological landscape, artefacts and an extensive in-situ skeletal record in the context of a detailed palaeoenvironmental study. It will provide a new cultural-environmental history of this landscape and provide the Mithaka with multiple strands of connection to their ancestral land and culture and support their aspirations to create employment through rangers programs, education and cultural tourism.Read moreRead less
Long range toxic metal pollution in Australia and the Southern Ocean. This project aims to investigate how environmental change and human activities since industrialisation have impacted toxic metal transport and deposition on the south coast of Australia, Tasmania and Southern Ocean islands.

This project aims to investigate how environmental change and human activities since industrialisation have impacted toxic metal transport and deposition on the south coast of Australia, Tasmania and Southern Ocean islands. This project expects to fill gaps in understanding of the global mercury cycle using a state-of-the-art multidisciplinary methodology including the role of sea salt aerosols and hemispheric-scale wind patterns . Anticipated outcomes involve a novel palaeo-atmospheric model that can be applied in other parts of the world. This should provide significant benefits, such as science-based evidence to ratify the Minamata Convention on Mercury and guide new regulations to reduce environmental/health risks from metal pollution.

Global climate change and coastal landscape evolution in southern Australia. This project aims to reconstruct environmental changes that occurred in southern Australia during a geologically recent time interval termed the Early-Middle Pleistocene Transition (1.2 million to 700 thousand years ago) and an interglacial period some 400,000 years ago. Using innovative geochronological, geochemical and modelling techniques, the environmental changes that shaped modern Australian coastal landscapes, in ....Global climate change and coastal landscape evolution in southern Australia. This project aims to reconstruct environmental changes that occurred in southern Australia during a geologically recent time interval termed the Early-Middle Pleistocene Transition (1.2 million to 700 thousand years ago) and an interglacial period some 400,000 years ago. Using innovative geochronological, geochemical and modelling techniques, the environmental changes that shaped modern Australian coastal landscapes, including the intensification of aridity and their timing will be examined. The project will yield new knowledge about the sensitivity of landscapes to current and ongoing environmental changes and derive explanatory models of the rates and characteristics of landscape response to assist future coastal environmental management.Read moreRead less

This project aims to understand the impacts of water stressed environments for early modern human behaviour through state-of-the-art excavation techniques and palaeoenvironmental reconstruction at two new archaeological sites in the Kalahari. How humans mitigated water stress during a major technological transition is significant because adaptability to arid environments was crucial for humans expanding beyond Africa and into Australia. The expected outcome of this project is creation of new knowledge on the origins of human resilience to water stress. The benefit lies in the potential to gain insights into meeting future climate challenges by exploring the adaptive strategies developed by early modern humans in the southern Kalahari.Read moreRead less

Characteristics and controls of ice sheet loss on centennial timescales. This project aims to unearth the characteristics and controls of Antarctic ice sheet loss on timescales of 100s to 1000s of years. The polar ice sheets are getting smaller at an accelerating rate in response to a warming climate, but modern observations are not yet sufficient to determine whether current ice sheet loss marks the start of irreversible retreat.

This project aims to unearth the characteristics and controls of Antarctic ice sheet loss on timescales of 100s to 1000s of years. The polar ice sheets are getting smaller at an accelerating rate in response to a warming climate, but modern observations are not yet sufficient to determine whether current ice sheet loss marks the start of irreversible retreat. Through a combination of novel geological approaches and numerical ice-flow modelling, this project expects to generate new knowledge on the rates and magnitudes of ice sheet loss, and the processes that will dictate the amount of ice loss in this century and beyond. This work should be beneficial for managing the societal, economic and environmental impacts of future sea-level rise.Read moreRead less
