Linking River Health with Urban Drains: the Swan-Canning River Case Study. The continuous deterioration of the Swan-Canning estuary in WA has triggered the need to identify the effects of chronic contamination on biota. Contaminant entry points into the river have been identified as being urban drains and the Helena river. The aim of this research is to relate effects observed in 'drain fish' to effects observed in 'river fish'. Biomarkers of fish health such as EROD and ECOD activities, DNA dam ....Linking River Health with Urban Drains: the Swan-Canning River Case Study. The continuous deterioration of the Swan-Canning estuary in WA has triggered the need to identify the effects of chronic contamination on biota. Contaminant entry points into the river have been identified as being urban drains and the Helena river. The aim of this research is to relate effects observed in 'drain fish' to effects observed in 'river fish'. Biomarkers of fish health such as EROD and ECOD activities, DNA damage, stress proteins, biliary metabolites, etc. will be compared between drain and river fishes. Chemical analysis of contaminants will complement biomarker determinations. The outcomes will be applicable Australia wide, and provide information to better manage urban drain systems to reduce their impacts on native biota.Read moreRead less
Integration of Surface Water and Ground Water Processes in Coastal Catchments. The hydrologic processes which describe surface water and groundwater movement often occur at completely different temporal and spatial scales. These two distinct flow regimes, however, are intrinsically coupled in coastal catchments in Australia. The superposition of local flow systems on a regional groundwater framework results in complex interactions which are difficult to accurately predict with existing numeric ....Integration of Surface Water and Ground Water Processes in Coastal Catchments. The hydrologic processes which describe surface water and groundwater movement often occur at completely different temporal and spatial scales. These two distinct flow regimes, however, are intrinsically coupled in coastal catchments in Australia. The superposition of local flow systems on a regional groundwater framework results in complex interactions which are difficult to accurately predict with existing numerical models, and are not truly understood even at the conceptual level. This work aims to study a single catchment at a very detailed level to allow for the production of a new integrated approach to the simulation of the complete hydrologic systemRead moreRead less
Ocean-reef interactions as drivers of continental shelf productivity in a changing climate. Poor coastal management results in the irreparable destruction of reef systems' function and biodiversity, nationally and globally. To manage marine resources effectively we must implement sustainable practices, including forward planning in the context of climate change. A critical limitation in determining appropriate actions is a poor understanding of mechanisms driving productivity. Our project will p ....Ocean-reef interactions as drivers of continental shelf productivity in a changing climate. Poor coastal management results in the irreparable destruction of reef systems' function and biodiversity, nationally and globally. To manage marine resources effectively we must implement sustainable practices, including forward planning in the context of climate change. A critical limitation in determining appropriate actions is a poor understanding of mechanisms driving productivity. Our project will provide key information on the oceanographic mechanisms supporting Australia's coastal systems, linking nutrient supply, physical drivers and climate. By linking all these factors we will both assist in determining appropriate ecosystem management, and provide a knowledge base to support adaptation to future changes in Australia's climate.Read moreRead less
Hydrodynamics of Fringing Reef Systems. Ningaloo Marine Park is part of the National Representative System of Marine Protected Areas. Coral reefs are in a state of decline worldwide, yet Ningaloo Reef has remained in a relatively pristine state. However, its close proximity to land makes it particularly vulnerable to human activities, which are forecast to significantly grow in the near future. Results from this project will advance our ability to predict circulation on reefs and other similar c ....Hydrodynamics of Fringing Reef Systems. Ningaloo Marine Park is part of the National Representative System of Marine Protected Areas. Coral reefs are in a state of decline worldwide, yet Ningaloo Reef has remained in a relatively pristine state. However, its close proximity to land makes it particularly vulnerable to human activities, which are forecast to significantly grow in the near future. Results from this project will advance our ability to predict circulation on reefs and other similar coastal systems. This will provide insight into various ecological processes that are linked to hydrodynamics (e.g. recruitment), and will provide a foundation for conducting risk analysis of processes that threaten the integrity of nearshore environments (e.g. contaminant spills).Read moreRead less

The Great Barrier Reef is a World Heritage Area, home to over 1 million species and provides Australia with $6 billion in annual revenue. The capacity to monitor Australia’s natural resources and changes in condition are integral components of a sustainably and adaptively managed resource. By providing key synoptic tools to comprehensively monitor water quality and ecosystem status, the project will contribute directly to an Environmentally Sustainable Australia and improve national capacity for responding to climate change and variability in coral reef environments. It will enable Australian remote sensing scientists to contribute knowledge and tools to the international community for application to coral reef and coastal waters globally. Read moreRead less

Quantifying eco-geomorphic linkages to enhance marine park management . This project aims to develop a novel framework for predicting the future resilience of reef-fronted coastal habitats within marine parks. Through innovative observations of reef-fronted coastal dynamics, it will quantify the relationships between coastline evolution, physical drivers, reef geomorphology, sediment supply and reef ecology. Expected outcomes include new practical tools and transferable knowledge that can identi ....Quantifying eco-geomorphic linkages to enhance marine park management . This project aims to develop a novel framework for predicting the future resilience of reef-fronted coastal habitats within marine parks. Through innovative observations of reef-fronted coastal dynamics, it will quantify the relationships between coastline evolution, physical drivers, reef geomorphology, sediment supply and reef ecology. Expected outcomes include new practical tools and transferable knowledge that can identify coastal regions that are sensitive to changing environmental conditions and/or reef ecology. These tools will enable marine managers to identify areas that are most vulnerable or resilient to change, allowing prioritisation of resources, conservation efforts, restoration activities, and management interventions.Read moreRead less

Understanding the impacts of different fire regimes (frequency, intensity, patchiness, size of fires) on high diversity shrublands will help CALM (the land managers) develop fire management prescriptions that ensure the conservation of rare and threatened flora, and maintain biodiversity. The research will identify relationships between weather, fuel and fire behaviour that is currently lacking for shrubland vegetation types. It offers advances in our understanding of ecosystem structure and function, with applied value in fire management for conservation and asset protection. The project contributes to development of ecological theory, and provides a scientific basis for improved management of Australia's unique natural heritage.Read moreRead less

This project aims to create new science that will enable the development of low-cost, miniaturised electrochemical sensors based on poly-ionic liquids. The chemistry of the materials will be tuned to selectively detect hazardous pollutants to enable trace concentration detection at analytically relevant levels. Fundamental behaviour of gases and solid contaminants dissolved in poly-ionic liquid/ionic liquid membranes will be uncovered, and their performance for sensing in real environments will be examined. It is expected that these advances will transform detection methods by taking sensing out of the lab and in to the hands of the everyday person, giving rapid and accurate knowledge about the concentration of hazards in the environment.Read moreRead less
