Summary
The geodynamics of past sea level changes. This project is designed to quantify the effect of flow deep within Earth’s interior on past sea-level changes and on the flooding history of Australia over the last 550 million years. The rise and fall of sea level has shaped our planet over time. This project plans to combine recent advances in tectonic reconstructions and dynamic Earth models with the global and Australian rock record. The intended outcome is to understand how the Earth’s surface is ....The geodynamics of past sea level changes. This project is designed to quantify the effect of flow deep within Earth’s interior on past sea-level changes and on the flooding history of Australia over the last 550 million years. The rise and fall of sea level has shaped our planet over time. This project plans to combine recent advances in tectonic reconstructions and dynamic Earth models with the global and Australian rock record. The intended outcome is to understand how the Earth’s surface is shaped by flow within its interior, and how these processes explain the sedimentary record. Project results have the potential to be used as an exploration tool to maximise Australia’s competitive advantage in exploring onshore sedimentary basins.Read moreRead less

Precise global time scale for the oxidation of Earth's atmosphere between 2.6 and 2.0 billion years ago. The rock record from 2600 to 2000 million years ago preserves evidence for dramatically fluctuating greenhouse and icehouse climates at the same time as, and possibly caused by, change from an oxygen-deficient to an oxygen-rich atmosphere. Although the global changes are well-documented, correlation of their timing and duration between continents is poorly constrained. This project aims to re ....Precise global time scale for the oxidation of Earth's atmosphere between 2.6 and 2.0 billion years ago. The rock record from 2600 to 2000 million years ago preserves evidence for dramatically fluctuating greenhouse and icehouse climates at the same time as, and possibly caused by, change from an oxygen-deficient to an oxygen-rich atmosphere. Although the global changes are well-documented, correlation of their timing and duration between continents is poorly constrained. This project aims to redress that problem by producing a precise calibration of the global changes by analysis of the rock records in Australia, Canada and South Africa. It will provide a much needed time framework within which long-term feedback between atmospheric composition and climate can be understood.Read moreRead less
Murray Basin: A unique archive of late Neogene global change. Salinization, soil erosion, groundwater depletion and surface water degradation are but a few of the inter-related environmental problems facing the Murray-Darling Basin. These problems require an understanding of the way in which shallow groundwater, salts and surface water interact with near-surface sediments. This project is aimed at a better understanding the nature of those near-surface sediments in the Murray Basin and how th ....Murray Basin: A unique archive of late Neogene global change. Salinization, soil erosion, groundwater depletion and surface water degradation are but a few of the inter-related environmental problems facing the Murray-Darling Basin. These problems require an understanding of the way in which shallow groundwater, salts and surface water interact with near-surface sediments. This project is aimed at a better understanding the nature of those near-surface sediments in the Murray Basin and how they were formed. If we can understand how the basin came to be the way it is (in the modern setting), we may better understand the way it might behave when subject to man-made changes like increased groundwater usage, etc.Read moreRead less

A walk on the wild side: understanding disease resistance across plants. Plants are in constant battle with pests and pathogens. Wild species host genetic diversity, providing sources of disease resistance, while the narrow genetic base of crop varieties leads to an increasing reliance on the unsustainable application of chemical fungicides. Here I will apply the latest genomics approaches to characterise disease resistance gene diversity across the plant kingdom. Comparison of gene diversity wi ....A walk on the wild side: understanding disease resistance across plants. Plants are in constant battle with pests and pathogens. Wild species host genetic diversity, providing sources of disease resistance, while the narrow genetic base of crop varieties leads to an increasing reliance on the unsustainable application of chemical fungicides. Here I will apply the latest genomics approaches to characterise disease resistance gene diversity across the plant kingdom. Comparison of gene diversity within and between plant families will improve our understanding of resistance gene evolution in wild species and the impact of domestication and breeding on resistance gene diversity. Translation of this knowledge will support breeding for crop resilience, leading to durable resistance and more sustainable crop productionRead moreRead less
PAST EAST ANTARCTIC ICE SHEET AND GLOBAL SEA-LEVEL VARIATIONS. Unique fossil-bearing, open marine sediments occur inland from the modern Antarctic coastline. These were deposited when a now-glaciated Antarctic basin became a marine embayment, during intervals of significantly reduced ice sheet volume and elevated global sea-level in the past.

Unique fossil-bearing, open marine sediments occur inland from the modern Antarctic coastline. These were deposited when a now-glaciated Antarctic basin became a marine embayment, during intervals of significantly reduced ice sheet volume and elevated global sea-level in the past. Urgent palaeontological, sedimentological and geochemical research on these sediments are vital to provide: directly datable in situ evidence for major ice sheet retreat and global sea-level rise in the past; and quantifiable data concerning the environment during such events; an innovative opportunity to improve predictions of Antarctica's response to global warming and answer international debate about past Antarctic Ice Sheet stability.Read moreRead less

Sand-filled canyons may be excellent petroleum reservoirs, however, interpretation of formation and sediment filling of these major deep marine features is controversial. This project seeks to elucidate the origin of canyons and associated basin floor fans by combining sedimentological data with seismic interpretation and modelling to generate new insights into the history of the Exmouth Sub-basin during the Latest Jurassic. In particular, this project provides an opportunity to explore the role of tectonism in canyon formation, the results of which will be of international interest. Geological models developed in this project will enhance our understanding of deep marine systems.Read moreRead less

Plants are in a constant battle with insect pests and there is an increasing reliance on chemical inputs for control. However there are incoming bans on some pesticides, and new approaches are required for pest management. The aim of this project is to develop a new strategy which exploits the dependence of herbivorous insects on phytosterols. Here, we will apply the latest genomics technologies in plants to produce non-utilizable sterols which will not support insect growth and reproduction, but will still allow the plant to function normally. We will demonstrate this in the important crop canola. Translation of this knowledge will support breeding for crop resilience, leading to durable resistance and more sustainable crop production.Read moreRead less
