A new approach to the U-series dating of fossil molluscs - a major advance for the earth and archaeological sciences. The development of a reliable method for accurately determining the age of fossil shells represents a breakthrough in the ability to date marine shoreline, lake, and other shell-bearing deposits (e.g. middens).

The development of a reliable method for accurately determining the age of fossil shells represents a breakthrough in the ability to date marine shoreline, lake, and other shell-bearing deposits (e.g. middens). This will present new opportunities for research of significant national benefit, particularly into the effects of climate change, including linked sea-level change and melting of ice sheets, the impact of sea-level change on coastal zones, and shifts in the amount and variability of rainfall in different regions. The method may also be used to estimate the frequency and size of large storm and tsunami events, earthquake risk, and the timing of prehistoric human migration and associated environmental impacts.

The Southern Ocean's role in determining atmospheric CO2 levels: new insights from novel biogenic silica records of seawater pH. About half the emissions from the burning of fossil fuel since the Industrial Revolution have been absorbed by the oceans. However, considerable uncertainty surrounds the consequences of and the extent to which the oceans will continue to sequester CO2 into the future. This research will improve existing limited knowledge of the key biological and related ocean process ....The Southern Ocean's role in determining atmospheric CO2 levels: new insights from novel biogenic silica records of seawater pH. About half the emissions from the burning of fossil fuel since the Industrial Revolution have been absorbed by the oceans. However, considerable uncertainty surrounds the consequences of and the extent to which the oceans will continue to sequester CO2 into the future. This research will improve existing limited knowledge of the key biological and related ocean processes that transfer CO2 between the surface and depth, and the poorly understood effects on marine ecosystems of increasing ocean acidity due to CO2 absorption. This knowledge will contribute to predicting the course of future climate change and gauging the impacts on marine life and production systems.Read moreRead less
Reconstruction of anoxic and toxic conditions in Australian lakes and ancient oceans. Sustainable water quality is a critically important issue for Australia's economic and social development.

Sustainable water quality is a critically important issue for Australia's economic and social development. To be able to predict and plan the future of Australia's lakes and estuaries, it is crucial to understand their ecological past and to determine their state prior to and post-European settlement. This project develops and applies novel methodologies to reconstruct the history of cyanobacterial blooms, eutrophication and anoxia in Australian waterways. It will help to identify human impact on water quality. The new methodologies, applied to ancient sedimentary rocks, will also yield information about the effect of environmental changes on early life on Earth, enforcing Australia's position in the study of global geochemical cycles.Read moreRead less
MILLENIAL-SCALE INSTABILITY OF SEA LEVEL AND THE CLIMATE SYSTEM: NEW ANALYSIS OF CORAL TERRACES IN PAPUA NEW GUINEA. Northern hemisphere climates switched repeatedly and abruptly between cold and warm states during the ice ages. This unexplained finding poses uncertainties about future climate. The exact chronology of past sea level and climatic changes is a key to the problem: this project aims to establish precise chronology through re-analysis of coral terraces at Huon Peninsula, PNG.

Northern hemisphere climates switched repeatedly and abruptly between cold and warm states during the ice ages. This unexplained finding poses uncertainties about future climate. The exact chronology of past sea level and climatic changes is a key to the problem: this project aims to establish precise chronology through re-analysis of coral terraces at Huon Peninsula, PNG. New U-series dating methods will give an accurately-timed record of sea level changes, which will be tightly locked to marine-sediment records of climatic change, by using sharp changes in atmospheric radiocarbon as universal marker horizons.Read moreRead less

Maintaining the quality of water and soil is a critically important issue for Australia's economic and social development. To be able to predict and plan the future of our natural assets, it is critical to understand their ecological past and their state before and after European settlement. We will utilize the new instrument to develop and apply innovative technologies providing Australia with new knowledge about the causes and effects of toxic cyanobacterial blooms, eutrophication, and contamination of reservoirs by bush-fires. The new facility will also supply advanced oil fingerprinting techniques to the petroleum industry minimizing exploration risk and increasing the chance of the discovery of new oil deposits.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

Summary
A new paradigm for quantifying the resilience of marine calcifiers to ocean acidification and global warming. This multi-disciplinary research project will determine the future of coral reefs and marine calcifiers in response to rising carbon dioxide and ocean acidification. This will enable best-practice adaptive management at local and regional-scales for marine-dependent industries, and provide new hope for some of our greatest natural assets, coral reefs.
