Groundwater and the Environment: Understanding the role of groundwater in the maintenance of sustainable ecosystems in Australia.
. 97% of freshwater on earth is groundwater. Despite this, it is undervalued, largely unexplored and poorly understood. In Australia, groundwater plays a critical role in our salinity problem and sustains our ecosystems. It will be a critical water supply in the future, especially in times of drought when surface water is scarce. Our nation's groundwater resources ....Groundwater and the Environment: Understanding the role of groundwater in the maintenance of sustainable ecosystems in Australia.

In Australia, groundwater plays a critical role in our salinity problem and sustains our ecosystems. It will be a critical water supply in the future, especially in times of drought when surface water is scarce. Our nation's groundwater resources require the same unresounding commitment to preservation that we now see in the Murray-Darling basin. This network develops foundations for a desperately needed National Groundwater Centre to provide research to ensure win-win outcomes for this country's water resources and the users that rely on them.

Understanding interglacial diversity. This project intends to improve our understanding of interglacial processes. Interglacials, the relatively brief warm intervals of Quaternary ice-age cycles, have varied significantly over the last 800 000 years in terms of their duration, timing, intensity and complexity. The reason for such diversity has eluded palaeoclimatologists for decades. This is because of the difficulty of dating marine and ice records, which best preserve interglacial histories.

The reason for such diversity has eluded palaeoclimatologists for decades. This is because of the difficulty of dating marine and ice records, which best preserve interglacial histories. The projects plans to compile precisely dated time series of past interglacials that can be linked directly to these records, allowing robust comparisons between interglacial properties and changes in Earth's astronomical parameters. This would advance palaeoclimate theory and provide a new perspective on the future evolution of the climate system.Read moreRead less

Summary
A mass spectrometer to analyse carbonate isotope records of Australia's climate, soil and groundwater history. Water is a critical resource in Australia, yet there is a fundamental lack of knowledge about the causes and timing of groundwater recharge in the past. This facility will allow researchers to better understand climate and groundwater interactions through high resolution isotope analysis of deposits, such as cave stalagmites and marine corals.
An integrated investigation of nutrient generation and delivery processes and pathways from paddock to small catchment scales. Improving water quality, primarily through reducing nutrient concentrations, remains a massive challenge for effective catchment management in Australia.

Improving water quality, primarily through reducing nutrient concentrations, remains a massive challenge for effective catchment management in Australia. Through a multidisciplinary approach including soil science, hydrology and aquatic chemistry, this project will develop an integrated catchment system understanding of water quality behaviour. This understanding will greatly improve the scientific underpinning of catchment water quality management and prediction, thus supporting improvements in the sustainability of Australia's water management. The work will focus on catchments with high intensity livestock grazing, which tend to be located in high rainfall areas near coasts where significant issues of water quality management exist.Read moreRead less

Summary
The further back we look, the further forward we can see: 1,000 years of past climate to help predict future climate change in Australia. Reconstructing 1,000 years of Australia's past climate will greatly extend our understanding of natural climate variability currently estimated from weather observations. For the first time, Australian climate variations over the last millennium will be used to assess the accuracy of climate model simulations for our region.
Optimisation of catchment management: stable isotope studies of water storage and yield. Focusing on the Cotter catchment, this project will establish how the water content of soils and tree stems regulates the amount of water used by trees in sub-catchments, and thus how much reaches streams and dams. Small areas supply most of the water yield and this project will help identify where managers should focus efforts to increase yield.
Quantifying near-surface diffuse discharge from the southwest Great Artesian Basin. Groundwater from the Great Artesian Basin (GAB) supplies one of Australia's largest mining operations and many pastoral enterprises. The GAB is the only significant water resource through much of arid central Australia and supports unique environmental values in this region. This project will provide vital data on natural, near-surface leakage rates from the GAB that can be used to gain a greater understanding of ....Quantifying near-surface diffuse discharge from the southwest Great Artesian Basin. Groundwater from the Great Artesian Basin (GAB) supplies one of Australia's largest mining operations and many pastoral enterprises. The GAB is the only significant water resource through much of arid central Australia and supports unique environmental values in this region. This project will provide vital data on natural, near-surface leakage rates from the GAB that can be used to gain a greater understanding of the amount of water available for sustainable extraction. This will assist in the improved management of the GAB resource and in doing so contribute to greater certainty for the mining and pastoral users of the GAB groundwater and provide greater protection for unique ecosystems associated with natural discharge springs.Read moreRead less

Isotope analyser with delta-17-O capability to examine water fluxes: This project aims to investigate a range of processes, including quantifying evaporative losses, moisture recycling, groundwater-surface water interactions, and records of past climate in ice cores using novel capabilities for continuous measurement of triple oxygen isotopes (16-O, 17-O, 18-O) in water vapour. Enhanced understanding of water cycles is critical for understanding the discrete changes occurring in water regimes under changing climates and land use to efficiently manage our limited freshwater resources. The instrumentation is intended to put Australia at the forefront of new and emerging research in d17O analysis of water, an area that has potential to greatly improve our understanding of the water cycle within arid climates including Antarctica.Read moreRead less
Climate-related regime shifts in inland semi-arid ecosystems through ecohydrological proxies. This project will investigate the dynamics of climate, especially rainfall, of the northwest of Australia over the last few thousand years. Our findings will increase understanding of climate variability and contribute to sustainable management of water and biodiversity in semi-arid Australia.
Sedimentary processes on sandy coasts in southern Australia. This project aims to reconstruct sedimentary processes and evolution of key coastal plains in southern Australia. These low-lying coasts, and the settlements and infrastructure on them, are vulnerable to inundation and shoreline erosion. Past behaviour of different types of coasts will be determined by combining innovative geospatial techniques to map morphology and past changes, geophysical imaging of stratigraphy and geochronology.

These low-lying coasts, and the settlements and infrastructure on them, are vulnerable to inundation and shoreline erosion. Past behaviour of different types of coasts will be determined by combining innovative geospatial techniques to map morphology and past changes, geophysical imaging of stratigraphy and geochronology. The outcome will be models that explain responses to sediment availability, past storm history and sea-level changes. This will benefit sustainable coastal planning and management, providing geomorphological evidence to support erosion hazard assessments of these and adjacent coasts.Read moreRead less
