Ocean heat content change and its impact on sea level. This project aims to improve projections of possible sea level changes. Sea level rise is among the most significant potential impacts of transient climate change around the world. Poor understanding of the way in which heat is absorbed at the sea surface and distributed by ocean circulation is a leading source of uncertainty in projections of global surface temperature and regional sea level rise by the end of this century. This project aim ....Ocean heat content change and its impact on sea level. This project aims to improve projections of possible sea level changes. Sea level rise is among the most significant potential impacts of transient climate change around the world. Poor understanding of the way in which heat is absorbed at the sea surface and distributed by ocean circulation is a leading source of uncertainty in projections of global surface temperature and regional sea level rise by the end of this century. This project aims to apply novel observational methods, complimented by numerical modelling, to quantify the drivers of recent change. This project expects to transform our ability to predict how ocean temperature and sea level will change in the future.Read moreRead less
The Southern Ocean boundary layer: winds, turbulence, sea spray and clouds. Both satellite products and climate models have large biases in the energy and water budgets over the Southern Ocean (SO). This is a direct consequence of a poor understanding of the structure and dynamics of the SO atmospheric boundary layer, which has arisen from an inability to make the necessary observations in this harsh environment. Due to the availability of new Australian research infrastructure, large steps forw ....The Southern Ocean boundary layer: winds, turbulence, sea spray and clouds. Both satellite products and climate models have large biases in the energy and water budgets over the Southern Ocean (SO). This is a direct consequence of a poor understanding of the structure and dynamics of the SO atmospheric boundary layer, which has arisen from an inability to make the necessary observations in this harsh environment. Due to the availability of new Australian research infrastructure, large steps forward are now possible with modest investment. This project will conduct and combine observations from the recently acquired marine vessel, RV Investigator, and the collocated airborne and surface observations to understand the structure and evolution of the unique, pristine SO boundary layer and to evaluate satellites and climate models.Read moreRead less
Multi-proxy fingerprinting, absolute dating, and large-scale modelling of Quaternary climate-volcano-environment impacts in southern Australasia. The discovery of Homo floresiensis (the Hobbit) revealed the surprising diversity of early humans and opened new ways for Australians and Indonesians to make tremendous scientific advances.

The discovery of Homo floresiensis (the Hobbit) revealed the surprising diversity of early humans and opened new ways for Australians and Indonesians to make tremendous scientific advances. Deployment of world-best analytical capabilities to untapped speleothem resources in Indonesia will put us at the forefront in understanding global climate change, volcanic catastrophes, and environmental impacts on deep-time cultures shared by our nations. Our findings will extend to the modern world, where humans modify climates and landscapes at unprecedented rates. Integration of Australian and Indonesian research strengths will showcase bilateral science, education, and training, and engage the public in the excitement of scientific discovery.Read moreRead less
Getting smaller as temperatures rise? Body size responses of Australian birds to climate change. Many animals appear to be declining in size as climate change occurs, but why this is so is unclear. Using historical records and museum specimens we will determine the factors underlying body size reductions in Australian birds, and especially the role of changing temperature and ecosystem productivity.
Australian savannah landscapes: past, present and future. Australian savannahs are productive and culturally and biologically significant landscapes but are vulnerable to climate change. The project will determine savannah function (carbon and water balance) for the present and assess how sensitive they have been to past climate variability. The project will then address how they may respond to future climate change.

This project aims to produce a multifaceted history of the eastern Tibetan Plateau's rivers, focusing on the increasing human impacts during the Anthropocene. It will combine data from archival, cultural and oral sources in multiple languages with the results of scientific studies of river flow, water quality, and sediment, ice, and tree-rings analysis. The project will produce both historical narratives and graphic representations that model past land and water usage. The results of the project will underpin environmental policy for this hydrologically and ecologically crucial region, including the development of a paradigm of care based on the region's indigenous cultural resources.Read moreRead less
Predicting environmental extremes in a period of climate change. This project has the potential to reduce the uncertainty in the predictions of extreme winds and waves used to design and operate coastal and offshore facilities. Predictions are typically achieved by extrapolating recorded data to predict probable extremes. The uncertainties associated with this approach are very large. This project aims to develop a new approach called ‘large ensemble aggregate’ analysis, which brings together da ....Predicting environmental extremes in a period of climate change. This project has the potential to reduce the uncertainty in the predictions of extreme winds and waves used to design and operate coastal and offshore facilities. Predictions are typically achieved by extrapolating recorded data to predict probable extremes. The uncertainties associated with this approach are very large. This project aims to develop a new approach called ‘large ensemble aggregate’ analysis, which brings together data from alternative model predictions or alternative measurement locations to expand the effective data and avoid the necessity for statistical extrapolation. This approach may significantly reduce the uncertainty in estimating extreme values. This would reduce the cost of constructing coastal and offshore facilities and decrease the risk of catastrophic failure.Read moreRead less
