Summary
Mass spectrometry for next generation isotope analysis of silicate minerals. This project aims to establish a facility for mass spectrometry and sample preparation to enhance Australian capacity to analyse the stable isotope composition of silicate minerals. The project seeks to implement innovations that will greatly enhance the use of stable isotopes in silicate minerals by increasing analytical throughput and reducing cost.

This project aims to establish a facility for mass spectrometry and sample preparation to enhance Australian capacity to analyse the stable isotope composition of silicate minerals. The project seeks to implement innovations that will greatly enhance the use of stable isotopes in silicate minerals by increasing analytical throughput and reducing cost. This will provide better understanding of the trajectories of environmental change, formation of mineral deposits and identifying trade networks in prehistoric societies.Read moreRead less
Unravelling the drivers of greenhouse gas emissions in estuaries. The aim of this project is to understand and quantify the factors controlling the emission of carbon dioxide, methane and nitrous oxide from estuaries. Coastal systems play a disproportionately large role in the global emissions of greenhouse gases, but this is poorly quantified. The project plans to use a combination of continuous concentration and stable isotope measurements, process measurements and advanced numerical modelling ....Unravelling the drivers of greenhouse gas emissions in estuaries. The aim of this project is to understand and quantify the factors controlling the emission of carbon dioxide, methane and nitrous oxide from estuaries. Coastal systems play a disproportionately large role in the global emissions of greenhouse gases, but this is poorly quantified. The project plans to use a combination of continuous concentration and stable isotope measurements, process measurements and advanced numerical modelling across a range of undisturbed to disturbed systems. It is intended that this project will provide information for conceptualising, calibrating and verifying models, including green-house gas production. Good models, and the data that support them, such as that provided by this study, are critical for the efficient allocation of management resources in Australian coastal systems, including by our partners. The findings from this project will have direct implications to the management, rehabilitation and protection of waterways (including biodiversity) in Australia.Read moreRead less
Unravelling the cycling of nitrogen along a subtropical freshwater-marine continuum using a multi-isotope, multi-tracer and modelling approach. This project will significantly advance our understanding of the sources, cycling and pathways of nitrogen along a sub-tropical catchment-river-estuary. As such, the findings from this research will have direct implications to the management, rehabilitation and protection of waterways (including biodiversity) in Australia.
Electron flow in iron hyper-enriched acidifying coastal environments: reaction paths and kinetics of iron-sulfur-carbon transformations. Iron hyper-enriched acidifying coastal lowlands have a direct social, economic and environmental impact on communities in many parts of Australia. This project will determine how iron transforms and accumulates. The new knowledge will be of immediate relevance for the remediation of coastal plains.
Fish fingerprints - signatures of oil contamination. The project aims to integrate chemical characterisation of crude oil with inorganic and organic markers in living organisms. Linking harmful effects on ecosystems with exposure to spilled crude oil remains a major challenge due to the ever-changing nature of oil in the environment. This project will expose fish to a range of fresh/weathered oils to mimic various exposure scenarios. The transition of oil to metabolites will be characterised in ....Fish fingerprints - signatures of oil contamination. The project aims to integrate chemical characterisation of crude oil with inorganic and organic markers in living organisms. Linking harmful effects on ecosystems with exposure to spilled crude oil remains a major challenge due to the ever-changing nature of oil in the environment. This project will expose fish to a range of fresh/weathered oils to mimic various exposure scenarios. The transition of oil to metabolites will be characterised in a suite of environmental and biological matrices using multi-dimensional chromatography/mass spectrometry, trace metals and compound-specific isotope analyses. This project will provide significant benefits by providing an improved capacity to link source oil with specific markers in living organisms.Read moreRead less
Unravelling how aquatic coastal networks regulate nitrogen removal . The aim of this project is to determine the nitrogen removal pathways of the coastal zone using a number of innovative field and modelling approaches. Little is known about how the complex coastal landscape controls trade-offs that maximise nitrogen removal but minimise nitrous oxide (a potent greenhouse gas) emissions. The outcomes of this study will significantly advance our understanding of the coastal zone in regional and g ....Unravelling how aquatic coastal networks regulate nitrogen removal . The aim of this project is to determine the nitrogen removal pathways of the coastal zone using a number of innovative field and modelling approaches. Little is known about how the complex coastal landscape controls trade-offs that maximise nitrogen removal but minimise nitrous oxide (a potent greenhouse gas) emissions. The outcomes of this study will significantly advance our understanding of the coastal zone in regional and global nitrogen budgets. This will provide significant benefits such as a new science-based quantitative framework to facilitate best practice management to reduce terrestrial nitrogen loads and associated downstream impacts such as eutrophication, and reduce nitrous oxide emissions and associated global warming.

Interpreting the molecular record in extraordinarily preserved fossils. This project aims to unlock a hidden record of our planet’s past and the life it supported, using a novel approach with benefits for environment and industry. Soft tissues preserved in sedimentary concretion fossils will be analysed, extending the traditional inorganic fossil framework of major evolutionary events. Understanding the biofilm entombment and preservation mechanisms responsible for this unique organic fossil arc ....Interpreting the molecular record in extraordinarily preserved fossils.

Soft tissues preserved in sedimentary concretion fossils will be analysed, extending the traditional inorganic fossil framework of major evolutionary events. Understanding the biofilm entombment and preservation mechanisms responsible for this unique organic fossil archive will extend our knowledge of microbial functionality. Expected outcomes from this new way of interpreting our planet’s past, include improved understanding of extinction events, environmental change and adaptation, with potential benefits in ecosystem management, resource exploration and biofilm uses.Read moreRead less

This project aims to determine how non-conventional lithium and silicon isotopes can be used to understand groundwater processes using an innovative source-to-target approach. The project aims to apply these isotope tracers to trace the water cycle within a well constrained system: an island aquifer with a dense borefield which has been analysed using traditional isotopic techniques. Supporting hydrochemical data will be used to determine the relationship of the isotopes with environmental processes. The project impact will be the development of new methods to help understand our groundwater resource. The improved process understanding will be translated to groundwater management in general. The projects' focus on carbonate aquifer systems typical of coastal regions of southern, eastern and western Australia will have relevance to groundwater management in urban areas such as Perth and in rural areas for tourism and viticulture, and for management of natural resources in National Parks.Read moreRead less
The recovery of life recorded at the end-cretaceous impact crater. This project aims to provide new insights into how the Earth and its ecosystems respond to catastrophic events and dramatic shifts in climate. Sharp changes in climate and ocean circulation can place ecosystems under severe stress.
