Defining the relationship between microscale wave breaking and enhanced air-water interfacial exchange rates of low solubility gases. Accurate parameterisations of absorption rates of low-solubility gases (e.g. oxygen, carbon dioxide) across open air-water interfaces are important to industry and the environmental sciences, e.g. for estimating carbon dioxide transfer rates in industry and the global environment as well as rates of the re-aeration of nutrient-enriched water. Recent studies show t ....Defining the relationship between microscale wave breaking and enhanced air-water interfacial exchange rates of low solubility gases. Accurate parameterisations of absorption rates of low-solubility gases (e.g. oxygen, carbon dioxide) across open air-water interfaces are important to industry and the environmental sciences, e.g. for estimating carbon dioxide transfer rates in industry and the global environment as well as rates of the re-aeration of nutrient-enriched water. Recent studies show that at open air-water interfaces under moderate wind forcing, absorption rates are primarily determined by microscale wave breaking. This project will determine the dependence of gas flux rates on the scale, strength and intermittency of microscale wave breaking and, by incorporating this key process, produce substantially improved predictive schemes.Read moreRead less
Nano- and micro-scale engineering of MoS2-based catalyst for conversion of syngas to ethanol. Domestic production of ethanol to provide a 10% blend in petrol (E10) can be achieved from waste methane gas that Australia currently vents or flares to atmosphere. This project aims to develop a conversion process for making ethanol from syngas (the product of coal or methane gasification). Small scale, modularised plants would make ethanol locally to the methane emission source. The benefits of local ....Nano- and micro-scale engineering of MoS2-based catalyst for conversion of syngas to ethanol. Domestic production of ethanol to provide a 10% blend in petrol (E10) can be achieved from waste methane gas that Australia currently vents or flares to atmosphere. This project aims to develop a conversion process for making ethanol from syngas (the product of coal or methane gasification). Small scale, modularised plants would make ethanol locally to the methane emission source. The benefits of local E10 production would be a reduction in the oil trade deficit of $1 billion per year, $500 million per year in lower carbon imposts to industry and government, 25 million tonnes per year of reduced CO2e release to atmosphere and significantly improved urban air through reduced emissions from car transport, with attendant human health benefits.Read moreRead less
Quantifying the role of the Southern Ocean for anthropogenic CO2 uptake. Carbon dioxide (CO2) is the most important greenhouse gas contributing to global warming and climate change. Climate change is likely to have dramatic economic and environmental consequences for Australia. Knowledge and understanding of the complex carbon cycle is fundamental for predicting future atmospheric CO2 levels and managing climate change. The aim of the work proposed here is to quantify and improve our understan ....Quantifying the role of the Southern Ocean for anthropogenic CO2 uptake. Carbon dioxide (CO2) is the most important greenhouse gas contributing to global warming and climate change. Climate change is likely to have dramatic economic and environmental consequences for Australia. Knowledge and understanding of the complex carbon cycle is fundamental for predicting future atmospheric CO2 levels and managing climate change. The aim of the work proposed here is to quantify and improve our understanding of the oceans role in controlling atmospheric CO2 levels. This will be done by combining modeling and observational expertise among UNSW and CSIRO (Marine Research) researchers. Our work will be the first to assess the extent of which the Southern Ocean (and Australian waters) acts as a carbon sink. This will reduce modeling uncertainties in predicting future atmospheric CO2 levels and will also be valuable to the federal government in future international negotiations on climate change.Read moreRead less
Development of Environmental Health Indicators in the Context of Sustainable Development. Protecting and promoting community well-being and population health is an essential aspect of sustainable development (SD). It is critical, therefore, to develop rigorous environmental health indicators (EHIs) to provide solid bases for the planning of SD and environmental management decision-making. However, a framework for the development of EHIs has not been attempted.

Protecting and promoting community well-being and population health is an essential aspect of sustainable development (SD). It is critical, therefore, to develop rigorous environmental health indicators (EHIs) to provide solid bases for the planning of SD and environmental management decision-making. However, a framework for the development of EHIs has not been attempted. This research aims to increase fundamental knowledge on the relationship between EHIs and SD, to identify a core and extended set of EHIs, and to assess implications of EHIs in the planning of SD and environmental management. A framework for identification and application of EHIs will be developed.Read moreRead less

The project helpins students in Australia more deeply understand the sciences that underlie environmental sustainability. Learning with modelling and visualization technologies will help students learn important scientific knowledge and prepare them for the use of frontier technologies that are becoming infused into the practices of scientists and professionals in many fields. This project also directly contributes to the national Digital Education Revolution initiative.Read moreRead less
Managing Ecosystem Change in the Greater Blue Mountains World Heritage Area. Protected areas are the primary mechanism for conserving Australia's unique biodiversity. Of added significance are areas of biodiversity recognised as World Heritage Areas, such as the GBMWA. Climate, pest species and altered fire regimes potentially diminish their ecological values but some of these anthropogenic threats can be managed. Effective management depends on spatially-explicit understanding that allows prior ....Managing Ecosystem Change in the Greater Blue Mountains World Heritage Area. Protected areas are the primary mechanism for conserving Australia's unique biodiversity. Of added significance are areas of biodiversity recognised as World Heritage Areas, such as the GBMWA. Climate, pest species and altered fire regimes potentially diminish their ecological values but some of these anthropogenic threats can be managed. Effective management depends on spatially-explicit understanding that allows priorities to be set and management objectives identified and tested. This research will develop a model for determining management priorities for large protected areas, meeting State, National and International obligations. Significant conservation benefits will accrue along with social, economic and human well-being benefits.Read moreRead less
Science and Citizenship: Democracy in the age of science-mediated risk. This community-based project in the Goulburn Valley focuses on citizens' negotiation of scientific expertise, perceptions of risk and participation in policy formation.

The project will produce an environmental history drawn from citizens' experience of transforming the landscape for irrigation and agribusiness, and of scientific advice ov ....Science and Citizenship: Democracy in the age of science-mediated risk. This community-based project in the Goulburn Valley focuses on citizens' negotiation of scientific expertise, perceptions of risk and participation in policy formation. It asks: 'how can democracy work in a world of proliferating cultures of expertise?' The project will produce an environmental history drawn from citizens' experience of transforming the landscape for irrigation and agribusiness, and of scientific advice over time. It will explore how citizens deal with conflicting scientist-generated scenarios around climate change and environmental flows in the light of their historical experience, and trial new modes of public policy formation.Read moreRead less
