A 140,000 year insight into the imprint of climate and humans on Australia. Before the arrival of Europeans, two events shaped Australia's current landscapes and biota more than any others: climate change during the glacial cycle and the arrival of humans on the continent. However, the full scale of these events is not well understood. High resolution analyses of two continuous 140 000 year old sediment deposits will be used in this project to fill this void and answer fundamental questions abou ....A 140,000 year insight into the imprint of climate and humans on Australia.

Fire and rain: Drivers of deep-time ecosystem assembly in Australia. This project aims to investigate the influence of bushfires and shifting rainfall patterns on the development of Australia’s dominant ecosystems. By combining a range of novel geochemical, isotopic and palaeontological techniques, this research seeks to reveal the causes and consequences of Australia’s transformation from a forested to mainly open landscape of grassland, shrubland and savannah. The expected outcome is detailed ....Fire and rain: Drivers of deep-time ecosystem assembly in Australia. This project aims to investigate the influence of bushfires and shifting rainfall patterns on the development of Australia’s dominant ecosystems. By combining a range of novel geochemical, isotopic and palaeontological techniques, this research seeks to reveal the causes and consequences of Australia’s transformation from a forested to mainly open landscape of grassland, shrubland and savannah. The expected outcome is detailed knowledge of how changes in fire and rain shaped the ecology and evolution of plants and animals. This knowledge is key to understanding how Australian ecosystems function and to protecting their cultural, economic and environmental values, especially as climate and fire regimes continue to change into the future.Read moreRead less
From prehistory to history: landscape and cultural change on the South Alligator River, Kakadu National Park. This project explores the archaeology, history and palaeoecology of the Kakadu floodplains to better understand social and environmental changes that have taken place in this landscape from the mid-Holocene to historical times. The outcome will be a contextualised understanding of potential climate change impacts against a history of past change.
Archaeological investigations at ancient sites in Kakadu National Park. This project aims to re-examine two well-known sites (Malangangerr and Ngarradj) in Kakadu, an iconic World Heritage area and home to some of the oldest and richest archaeology in Australia. Little excavation has been carried out there in recent decades, and almost none using modern high resolution recovery techniques. This project will re-excavate Malangangerr and Ngarradj to determine whether other sites have a similar ant ....Archaeological investigations at ancient sites in Kakadu National Park. This project aims to re-examine two well-known sites (Malangangerr and Ngarradj) in Kakadu, an iconic World Heritage area and home to some of the oldest and richest archaeology in Australia. Little excavation has been carried out there in recent decades, and almost none using modern high resolution recovery techniques. This project will re-excavate Malangangerr and Ngarradj to determine whether other sites have a similar antiquity and record of early complex behaviour. This project could enhance understanding of Aboriginal culture in Kakadu, Australia's unique cultural heritage, the nature and timing of modern human dispersal, and how early Indigenous peoples responded to social and environmental change.Read moreRead less

Summary
Investigating the synchroneity of global atmospheric shifts in the Holocene. The austral mid-latitude westerly winds dominate Southern Hemisphere climate variability today (including the Australasian region) and are tightly coupled to the Southern Ocean, modulating the air-sea CO2 flux. However, short instrumental records in the south make future climate projections uncertain. This Project will develop the first highly-detailed reconstructions of westerly airflow from targeted Southern Ocean isl ....Investigating the synchroneity of global atmospheric shifts in the Holocene. The austral mid-latitude westerly winds dominate Southern Hemisphere climate variability today (including the Australasian region) and are tightly coupled to the Southern Ocean, modulating the air-sea CO2 flux. However, short instrumental records in the south make future climate projections uncertain. This Project will develop the first highly-detailed reconstructions of westerly airflow from targeted Southern Ocean islands during key periods of change, representing a range of climate states over the Holocene (the last 11,650 yrs). Intensive radiocarbon dating will allow precise alignment to a network of palaeoclimate records to test the timing, drivers and impacts of circulation change across Australia and globally.Read moreRead less

This project aims to produce the first long-term (100,000 year), replicated, high-resolution terrestrial records of environmental change before, during and after the arrival of humans in Australian savannas. These records will be the first in the world to extract, from the same material, independent, cutting-edge organic and isotope geochemical records of ch ....What is natural?

This project aims to produce the first long-term (100,000 year), replicated, high-resolution terrestrial records of environmental change before, during and after the arrival of humans in Australian savannas. These records will be the first in the world to extract, from the same material, independent, cutting-edge organic and isotope geochemical records of changes in water balance, vegetation type and fire activity. This will enable natural and human drivers of change in northern Australia's climate and biodiversity to be disentangled on two timescales: millennial: before, during and after Aboriginal arrival in northern Australia and centennial: before, during and after European arrival in northern Australia.Read moreRead less
Unlocking the environmental archives of the Kimberley’s past. This project aims to reconstruct the environmental history of Australia’s Kimberley region spanning the past 60,000 years.

The archaeology of Thailand and Myanmar: A Strategic Region for Understanding Modern Human Colonization and Interactions Across our Region. At a crossroads between India, Australia and the Pacific, this project recognises western mainland Southeast Asia as critical to understanding the human history of the region over the past 50 000 years. Thailand and Myanmar are strategically positioned to test competing models of initial modern human expansion, and subsequent trajectories of cultural change ....The archaeology of Thailand and Myanmar: A Strategic Region for Understanding Modern Human Colonization and Interactions Across our Region. At a crossroads between India, Australia and the Pacific, this project recognises western mainland Southeast Asia as critical to understanding the human history of the region over the past 50 000 years. Thailand and Myanmar are strategically positioned to test competing models of initial modern human expansion, and subsequent trajectories of cultural change and interaction. This project aims to produce multiple data sets for reconstructing palaeoclimate. This data will assist in testing projections for future climate, making a significant contribution in responding to climate change and variability.Read moreRead less
Environmental Transformations linked to Early Human Occupation in Northern Australia. How have interactions between climatic change, human activities and other disturbances over thousands of years shaped the landscapes we know today in Australia? Existing lines of evidence from palaeoecological and archaeological sources point to significant changes to biodiversity, vegetation cover, and fire frequency since the arrival of people into Australia sometime between 50000 to 40000 yr BP. The extent t ....Environmental Transformations linked to Early Human Occupation in Northern Australia. How have interactions between climatic change, human activities and other disturbances over thousands of years shaped the landscapes we know today in Australia? Existing lines of evidence from palaeoecological and archaeological sources point to significant changes to biodiversity, vegetation cover, and fire frequency since the arrival of people into Australia sometime between 50000 to 40000 yr BP. The extent to which humans influenced or overrode natural processes through time remains unclear. High-resolution, multi-proxy data in an innovative vegetation and megafaunal reconstruction will provide the first quantitative assessment of the response of Australian tropical savannas to a range of natural and anthropogenic influences.Read moreRead less
