The causes and effects of mortality in tropical Australian trees. Drought can cause the widespread death of tropical trees resulting in large emissions of carbon dioxide to the atmosphere, but predictions of tree death during drought remain rudimentary. This project will combine new data and modelling on how Australian tropical trees respond to drought to improve estimates of tree mortality risk and its impacts.
Drought effects on soil carbon and nitrogen cycling mediated by rhizosphere processes. There is much uncertainty about how drought caused by global warming will affect agricultural sustainability in Australia. This project will provide new knowledge about plant-soil interactions affecting carbon and nutrient cycling and will make predictions about long-term soil carbon storage and agricultural productivity in response to drought.
Improved theory and practice in econometric modelling of nonlinear spatial time series. Modern Australia faces many challenges in economic and global climate changes, which require advanced statistical technologies in modeling and forecasting of econometric spatial time series data. This project will provide flexible models and methods that enable practitioners to more accurately measure and manage economic and climatic risks.
Dynamics of the Southern Ocean. The Southern Ocean is critically important to future global climate: it controls the natural global carbon cycle and the distribution of heat and nutrients around the ocean. This project will investigate key uncertainties in the Southern Ocean's response to climate change, and thereby improve our capacity to predict future climate.
Physical processes in complex coastal reef environments: the dynamics of wave- and tide-dominated systems. Coastal reefs are ubiquitous features of Australia's coastline, yet the dynamics controlling water motion on reefs still remain poorly understood. This project will significantly advance our understanding of coastal processes within reef environments, thus improving predictions of the impacts of extreme storms and climate change on our coasts.
Integrating biomechanics and ecology: moving from an individual- to population-level understanding of the effects of environmental change. Coral reefs, a key Australian resource, face an uncertain future due to environmental change. Up to now, environmental change research has focused on the individual level, severely limiting our predictive capacity. This project will develop a novel 'first principle' approach to solve this shortcoming and make population-level predictions possible.
How will climate change affect sub-daily precipitation? This project will examine changes in sub-daily precipitation due to climate change. It will improve our understanding of the mechanisms that cause the changes at regional and local scales. Regional climate change projections produced will be freely available, and at a spatial and temporal scales suitable for impacts and adaptation studies.
New laser-based approaches for remote sensing of water properties. New approaches for remote sensing of water properties such as temperature and salinity will be developed. Outcomes such as rapid vertical profiling of water temperature and salinity will contribute to environmental issues such as climate change and waterway health, while the ability to measure tissue temperature will contribute to human health.
What caused abrupt climate change events in the past and what can they tell us about the future? This project will improve our understanding of abrupt climate change in the past, present and future. It will dramatically enhance Australia's capacity to use climate models to assess the probability and associated consequences of abrupt climate change in the future.
Oceanic gateways: a primary control on global climate change? The opening and closing of oceanic gateways, narrow passageways facilitating exchange between ocean basins, has been linked to major changes in Earth’s climate. This project will link the disparate fields of geodynamics and palaeo-climatology, for the first time, through an innovative methodology that models the changing width and depth of ocean gateways through time. It will address the role of gateways in modulating Earth’s climate ....Oceanic gateways: a primary control on global climate change? The opening and closing of oceanic gateways, narrow passageways facilitating exchange between ocean basins, has been linked to major changes in Earth’s climate. This project will link the disparate fields of geodynamics and palaeo-climatology, for the first time, through an innovative methodology that models the changing width and depth of ocean gateways through time. It will address the role of gateways in modulating Earth’s climate at key periods during the planet’s transition from a “Greenhouse” to “Icehouse” World.Read moreRead less
