Unravelling soil carbon response to warming in fire-affected ecosystems. This project aims to reveal the continental pattern of soil carbon (C) response to warming in fire-affected ecosystems across Australia and to unravel the biogeochemical mechanisms underlying fire’s role in shaping the temperature sensitivity of soil respiration. Fire has modified over 40% of the Earth’s land surface and wildfire frequency is predicted to increase under global warming. This project expects to generate new k ....Unravelling soil carbon response to warming in fire-affected ecosystems. This project aims to reveal the continental pattern of soil carbon (C) response to warming in fire-affected ecosystems across Australia and to unravel the biogeochemical mechanisms underlying fire’s role in shaping the temperature sensitivity of soil respiration. Fire has modified over 40% of the Earth’s land surface and wildfire frequency is predicted to increase under global warming. This project expects to generate new knowledge on how fire influences soil-to-atmosphere C fluxes in a warmer climate using a multi-disciplinary approach. Expected outcomes include an enhanced capacity to predict the terrestrial ecosystem-to-atmosphere C fluxes and their feedbacks to climate under increasing frequency of fire using Earth-system models.

Building insights of our largest terrestrial carbon sink: rangelands soils. Rangelands soils represent Australia’s largest carbon sink. Yet, little is known about their potential for carbon sequestration or their vulnerability to climate and environmental change. This project leverages investments in national terrestrial observation platforms and integrates previous research outputs to develop new methods to measure and build understanding of soil carbon composition and dynamics in rangeland eco ....Building insights of our largest terrestrial carbon sink: rangelands soils. Rangelands soils represent Australia’s largest carbon sink. Yet, little is known about their potential for carbon sequestration or their vulnerability to climate and environmental change. This project leverages investments in national terrestrial observation platforms and integrates previous research outputs to develop new methods to measure and build understanding of soil carbon composition and dynamics in rangeland ecosystems. Under a framework that connects detailed measurements and small-scale processes, with machine-learning, data-model assimilation and large-scale next-generation biogeochemical modelling, it’ll allow more accurate predictions of soil carbon change and better decision-making to guide sustainable rangelands management.Read moreRead less
Realistic models of permeation in ion channels. Ion channels are formed by proteins in cell membranes and provide pathways for fast and controlled flow of selected ions. This activity generates action potentials in nerves and muscles that forms the basis of all movement, sensation and thought processes. Recent determination of the crystal structure of channel proteins has enabled construction of models that can relate channel function to its structure--necessary for understanding their operati ....Realistic models of permeation in ion channels. Ion channels are formed by proteins in cell membranes and provide pathways for fast and controlled flow of selected ions. This activity generates action potentials in nerves and muscles that forms the basis of all movement, sensation and thought processes. Recent determination of the crystal structure of channel proteins has enabled construction of models that can relate channel function to its structure--necessary for understanding their operation and seeking cures for diseases caused by their malfunction. This project aims to develop accurate ion-protein-water interactions for permeation models based on stochastic and molecular dynamics simulations using both classical and quantum mechanical methods.Read moreRead less
The First Deep Infrared Study of the Nearby Galaxy Population. We will conduct two major near-infrared (IR) surveys: The Southern Galactic Cap near-IR survey, and the Local Sphere of Influence survey. These surveys will capitalise on the innovative and award winning Australian IRIS2 facility. The two surveys push the observational frontier by orders of magnitude. They will be used to explore the close connection between the near-IR global properties of a galaxy and its underlying physics and pro ....The First Deep Infrared Study of the Nearby Galaxy Population. We will conduct two major near-infrared (IR) surveys: The Southern Galactic Cap near-IR survey, and the Local Sphere of Influence survey. These surveys will capitalise on the innovative and award winning Australian IRIS2 facility. The two surveys push the observational frontier by orders of magnitude. They will be used to explore the close connection between the near-IR global properties of a galaxy and its underlying physics and provide a generic local reference for the upcoming next generation infrared space-telescope missions.

The research addresses fundamental issues in the nature of the Universe and how our present world came to be. The spirit of exploration is contagious, and Australia's successes in astronomy are a source of national pride.
Observations of hydrogen gas have long been recognised as a key to following galaxy formation and evolution, and they are a key driver for building the Square Kilometre Array telescope, a project which could be sited in Australia. The SKA project is a multi-billion dollar project, which would bring international recognition and prestige. Development of the scientific expertise to motivate this project is an important part of establishing Australia's leadership role.Read moreRead less
Galactic Archaeology: A Radial Velocity Experiment to Unveil the History of the Milky Way. The ambitious RAdial Velocity Experiment (RAVE) will measure velocities and chemical properties of 50 million stars in the period 2006-2010 - 2000 times the number measured throughout history. RAVE will use a new-technology Australian fiber spectrometer at the Siding Spring UK Schmidt Telescope. A key demonstrator for RAVE is our proposed pilot survey using existing instruments to measure 100,000 stars - a ....Galactic Archaeology: A Radial Velocity Experiment to Unveil the History of the Milky Way.

RAVE will use a new-technology Australian fiber spectrometer at the Siding Spring UK Schmidt Telescope. A key demonstrator for RAVE is our proposed pilot survey using existing instruments to measure 100,000 stars - already 20 times larger than any previous survey - providing unique chemical and kinematical fingerprints of our Galaxy's formation. This is critical for determining the optimum observing strategy, data management, and software pipeline, before embarking on the full survey in 2006.Read moreRead less
The Last 8 Billion Years of Cosmic Evolution. A key factor in Australia's international prominence in astronomy has been the development and use of innovative instrumentation on its telescopes to undertake major leading-edge surveys. This project will enhance this reputation by using the new AAOmega facility on the 3.9m Anglo-Australian Telescope to make the largest ever survey of galaxies in the distant universe. This will allow us to address the two most important issues in cosmology today - ....The Last 8 Billion Years of Cosmic Evolution.

This project will enhance this reputation by using the new AAOmega facility on the 3.9m Anglo-Australian Telescope to make the largest ever survey of galaxies in the distant universe. This will allow us to address the two most important issues in cosmology today - the nature of the "dark energy" that is causing the universe's expansion to accelerate, and the detailed role of dark matter in galaxy formation and evolution.
