Remotely sensed forest water use in space and time. This project aims to develop and apply new methods to scale forest water use from plot to catchment-level, using relationships between plot-level annual evapotranspiration and biophysical and biochemical properties of stands detectable by unmanned aircraft systems and other remote sensing platforms. Australia's water security depends on understanding how changes in forests from disturbance and climate change influence catchment water yields. This project will estimate water yields over time and space in ungauged catchments with disturbed eucalypt forests. This research is expected to enable more effective risk mitigation and planning for augmentations; improved fire management strategies; and better water management of the Murray Darling Basin.Read moreRead less

Eddy-resolving global ocean-sea ice modelling. This project aims to develop a world-class global ocean-sea ice model framework through a nationwide consortium. The resulting high resolution models are expected to provide the foundation for the next decade of Australian ocean-sea ice modelling capacity. This research should lead to improved ocean and sea ice prediction, ocean reanalyses, and climate projections, enhancing Australia's capacity to predict the ocean state on timescales of days to decades. This is expected to yield efficiencies in shipping, marine search and rescue and naval operations, and increase the accuracy of projected future changes in climate, sea level, ocean ecosystems and the cryosphere.Read moreRead less

A novel top-down approach to ecosystem management using multivariate foraging strategies of an iconic marine top-predator. Understanding predator aggregation patterns in relation to marine productivity is critical in designing ecosystem-level conservation plans for protecting marine habitats and species. The project aims to develop a new approach to measure prey abundance and availability in the marine ecosystem for the management of resources of top-predators. This will be of specific benefit i ....A novel top-down approach to ecosystem management using multivariate foraging strategies of an iconic marine top-predator. Understanding predator aggregation patterns in relation to marine productivity is critical in designing ecosystem-level conservation plans for protecting marine habitats and species. The project aims to develop a new approach to measure prey abundance and availability in the marine ecosystem for the management of resources of top-predators. This will be of specific benefit in areas where a strong need exists for conservation of prey species with economic importance too low to justify expensive at-sea research.Read moreRead less
Are coastal wetlands vulnerable to bushfires? The ‘Black Summer’ fires burned extensive areas of coastal wetland not typically associated with fire impact. These wetlands rely upon plant growth and sediment delivery to respond to sea-level rise, processes which may be impacted by fire. This project aims to quantify the distribution and severity of fire impact, and establish post-fire vegetation and surface elevation trajectories. By integrating fire ecology and wetland science approaches, this p ....Are coastal wetlands vulnerable to bushfires? The ‘Black Summer’ fires burned extensive areas of coastal wetland not typically associated with fire impact. These wetlands rely upon plant growth and sediment delivery to respond to sea-level rise, processes which may be impacted by fire. This project aims to quantify the distribution and severity of fire impact, and establish post-fire vegetation and surface elevation trajectories. By integrating fire ecology and wetland science approaches, this project will ascertain the resilience of coastal wetlands to the cumulative impacts of fire and sea-level rise. Expected outcomes of this project include new, spatially-explicit fire management tools which will aid the sustainable, long-term management of coastal wetlands in a changing climate.Read moreRead less
Threats to the water quality and ecosystem of Coffin Bay, South Australia. Coffin Bay (South Australia) is experiencing worsening environmental conditions despite its major economic and ecological importance.

Coffin Bay (South Australia) is experiencing worsening environmental conditions despite its major economic and ecological importance. Research is needed to understand the cause of this decline, particularly in light of a recent bacterial outbreak that impacted the aquaculture industry. This multidisciplinary project aims to deliver world-leading scientific advice based on novel field techniques and innovative models of this complex inverse estuary system and its surrounding catchment. The new understanding of the sources, fluxes and fate of nutrients within the bay and the surrounding catchment, arising from this project, is expected to benefit management decision-making and establish a new standard in estuarine water quality investigation.Read moreRead less

Understanding of the behaviour of the nutrients controlling nuisance algae in water bodies is currently limited by the cost and logistics of collecting and analysing the large numbers of samples required.
This proposal describes the development and evaluation of portable multiparameter micro analysis systems that will be capable of high frequency measurements from a sampling vessel. This will enable environmental agencies to perform rapid on-site mapping of nutrients and other water quality parameters in large water bodies, intensive scale mapping of effluent mixing and dispersal zones, quick assessment of the impact of dredging and aquaculture, and compliance monitoring in effluent streams.

The recovery of seagrass beds: the role of catchments and options for management responses. Seagrass beds once dominated tidal flats but are disappearing at an increasing rate due to human actions, both in Australia and around the world. This project will develop an understanding of the processes that cause these losses, the factors that prevent seagrass-bed re-establishment, and provide a framework for evaluating alternative management options.
Anthropogenic influences on the source, transformation and fate of carbon and nitrogen in coastal waters: a case study of the Derwent Estuary. Ninety five percent of Australia's population live in the coastal zone on the shores of our major bays and estuaries. These water bodies are valuable resources for recreation, boating, fishing, marine transport and industry, but some activities, particularly the release of nitrogen, impose an environmental and economic cost. This project will significant ....Anthropogenic influences on the source, transformation and fate of carbon and nitrogen in coastal waters: a case study of the Derwent Estuary. Ninety five percent of Australia's population live in the coastal zone on the shores of our major bays and estuaries. These water bodies are valuable resources for recreation, boating, fishing, marine transport and industry, but some activities, particularly the release of nitrogen, impose an environmental and economic cost. This project will significantly advance our understanding of the natural processes that control the transformation and fate of nitrogen in coastal waters. As such the outcomes of this study will provide key information for managers on the environmental outcomes of nutrient management strategies.Read moreRead less
