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). This will present new opportunities for research of significant national benefit, particularly into the effects of climate change, including linked sea-level change and me ....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). 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.

Summary
High Performance Computing Infrastructure Upgrade. The aim of the High Performance Computing Facility is to operate a world class facility as measured by both computational power and client satisfaction. This proposal seeks to increase the current computational power of the existing Victorian High Performance Compting Facility by doubling the current capacity. The combination of a large number of very fast processors and a very fast interconnect makes this facility ideal for modelling and solv ....High Performance Computing Infrastructure Upgrade. The aim of the High Performance Computing Facility is to operate a world class facility as measured by both computational power and client satisfaction. This proposal seeks to increase the current computational power of the existing Victorian High Performance Compting Facility by doubling the current capacity. The combination of a large number of very fast processors and a very fast interconnect makes this facility ideal for modelling and solving science and engineering problems beyond the scope of installed HPC systems. The facility will be linked to other HPC systems in Victoria and across Australia to create an evolving cluster computing "meta-centre" that links computing resources together.

Three-dimensional flow, temperature and melting distributions in mantle subduction zones. We will predict spatial distributions and time evolution of temperature and magma production in subduction zones, where cold oceanic plates sink into the Earth's mantle, recycle crust and sediments, and generate volcanic arcs. Three-dimensional laboratory experiments, including 3-D flow visualization and high-resolution temperature measurements, will model slab segments, different rates and modes of subduct ....Three-dimensional flow, temperature and melting distributions in mantle subduction zones. We will predict spatial distributions and time evolution of temperature and magma production in subduction zones, where cold oceanic plates sink into the Earth's mantle, recycle crust and sediments, and generate volcanic arcs. Three-dimensional laboratory experiments, including 3-D flow visualization and high-resolution temperature measurements, will model slab segments, different rates and modes of subduction and upward transport of melt. Ocean trench migration (?rollback? subduction) is of special interest because it gives patterns of temperature and vertical motion most conducive to melting. Results will be used to interpret geochemical and seismic data from the Tonga subduction zone in the South Pacific.Read moreRead less
