Hydrogen: an overlooked intermediate during anoxia in permeable sediments. This project aims to quantify the respiratory pathways and the importance of hydrogen as an intermediate during anoxia in permeable (sand) sediments which dominate our coastline. It is anticipated the findings of this project will enable more accurate fundamental understanding of sediment diagenetic processes which control nutrient regeneration and loss pathways in the marine environment.

This project aims to quantify the respiratory pathways and the importance of hydrogen as an intermediate during anoxia in permeable (sand) sediments which dominate our coastline. It is anticipated the findings of this project will enable more accurate fundamental understanding of sediment diagenetic processes which control nutrient regeneration and loss pathways in the marine environment. This will enable better management of these environments in the face of increasing coastal population growth.Read moreRead less
Advanced micro analysis systems for environmental monitoring. 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 perfo ....Advanced micro analysis systems for environmental monitoring. 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.

Summary
A fisheries and oceanographic observing system for the continental shelf. This project aims to create a floating, mobile fisheries and oceanographic observing system for Eastern Australia. Australian oceanographic and fisheries research has been hampered by the lack of appropriately sized and equipped research vessels required to investigate continental shelf waters and beyond. The automated floating facility will provide data to support ongoing ARC-funded research programs in marine biogeochemi ....A fisheries and oceanographic observing system for the continental shelf. This project aims to create a floating, mobile fisheries and oceanographic observing system for Eastern Australia. Australian oceanographic and fisheries research has been hampered by the lack of appropriately sized and equipped research vessels required to investigate continental shelf waters and beyond. The automated floating facility will provide data to support ongoing ARC-funded research programs in marine biogeochemistry, climate change, ocean acidification, coastal hydrology, biological oceanography, active acoustics, and fisheries resources and technology in the continental shelf and beyond. The expected outcome will bridge a major gap in fisheries and oceanographic research capacity to make observations in a critical region of the Australian marine estate and provide a stronger scientific basis for early detection of changes in seawater chemistry, biology and fisheries in priority waters experiencing rapid change.Read moreRead less
Unravelling the nature of secular global climatic change on the Precambrian Earth. Ancient sedimentary rocks record evidence of major climate change and variations in the composition of the atmosphere. By applying novel isotopic and geochemical techniques, this project aims to document when and how the Earths atmosphere and climate changed prior to the evolution of complex lifeforms. Curiously, such dramatic climate changes have controlled both the rate of evoutionary process and the formation o ....Unravelling the nature of secular global climatic change on the Precambrian Earth. Ancient sedimentary rocks record evidence of major climate change and variations in the composition of the atmosphere. By applying novel isotopic and geochemical techniques, this project aims to document when and how the Earths atmosphere and climate changed prior to the evolution of complex lifeforms. Curiously, such dramatic climate changes have controlled both the rate of evoutionary process and the formation of world class mineral deposits.Read moreRead less
