The structural biology of light capture: A molecular resolution 3D atlas of the photosynthetic machinery. This project underpins the development of carbon dioxide (CO2)-neutral fuels for the future. Fuels account for around sixty seven percent of the global energy market. The Solar-Biofuels Consortium (www.solarbiofuels.org) is targeting this market by developing high efficiency second generation microalgal biofuel systems for the production of bio-diesel, bio-methane and bio-hydrogen (shown on ....The structural biology of light capture: A molecular resolution 3D atlas of the photosynthetic machinery. This project underpins the development of carbon dioxide (CO2)-neutral fuels for the future. Fuels account for around sixty seven percent of the global energy market. The Solar-Biofuels Consortium (www.solarbiofuels.org) is targeting this market by developing high efficiency second generation microalgal biofuel systems for the production of bio-diesel, bio-methane and bio-hydrogen (shown on Catalyst 2007). The solar-powered microalgal bioreactors can be located on non-arable land (eliminating competition with food production) and be coupled to carbon sequestration. Closed systems also minimize water use. This technology differs from most others (that is, clean-coal, nuclear, solar, wind, geothermal) as these target the electricity market.Read moreRead less
Coral Reefs Sensing Our Changing Climate. Australia's Great Barrier Reef is a valuable national and community resource, supporting commercial and recreation fishing and extensive national and international tourism along the length of Queenslands coastline. However it is an environment that is under threat from changing climate. The impact of a degraded reef environment is broad reaching, with effects on the Australian and Queensland economy and way of life. A better understanding of how this va ....Coral Reefs Sensing Our Changing Climate. Australia's Great Barrier Reef is a valuable national and community resource, supporting commercial and recreation fishing and extensive national and international tourism along the length of Queenslands coastline. However it is an environment that is under threat from changing climate. The impact of a degraded reef environment is broad reaching, with effects on the Australian and Queensland economy and way of life. A better understanding of how this valuable environment will respond to its changing environment is imperative and will provide us with a more informed basis on which to predict its future sustainability.

Changing Seas at Cellular to Cross-Ocean Scales. Australia relies greatly upon its rich natural environmental resources for goods, services and for economic growth (tourism, fisheries, and recreational industries). Climate change is one of the biggest threats to the natural marine environment. As the climate warms and oceans become more acidic, corals, the framework builders of reefs, experience unfavourable conditions. This project aims to better understand the processes by which ocean acidifi ....Changing Seas at Cellular to Cross-Ocean Scales. Australia relies greatly upon its rich natural environmental resources for goods, services and for economic growth (tourism, fisheries, and recreational industries). Climate change is one of the biggest threats to the natural marine environment. As the climate warms and oceans become more acidic, corals, the framework builders of reefs, experience unfavourable conditions. This project aims to better understand the processes by which ocean acidification and climate change affect corals, and to develop management tools for the mitigation of, and acclimation to, climate change. By so doing, this project will enable managers of Australia's Great Barrier Reef to better respond to the threatening challenges that climate change poses. Read moreRead less
Modelling the impact of simulated warming on marine microbial production of dimethylsulphide on a global scale. The ultimate goal of Earth systems science is to understand the planet's functioning well enough to explain past changes (eg ice ages) and to predict future states of the system (eg the magnitude of greenhouse warming). This is possible only if the climate system can be accurately modelled. This project aims to examine the effect of simulated climate change on the global production of ....Modelling the impact of simulated warming on marine microbial production of dimethylsulphide on a global scale. The ultimate goal of Earth systems science is to understand the planet's functioning well enough to explain past changes (eg ice ages) and to predict future states of the system (eg the magnitude of greenhouse warming). This is possible only if the climate system can be accurately modelled. This project aims to examine the effect of simulated climate change on the global production of dimethylsulphide (DMS) by marine microbial ecosystems. DMS has been hypothesised as an important biogenic feedback on global warming.
This work will provide the first ecosystem modelling estimates of the
global radiative forcing due to DMS and thus decrease the uncertainty in current climate projections.Read moreRead less
Environmental fingerprints of biogeochemical cycles embedded in tree rings: Linking global climate change to local long-term forest productivity. Forests cover one-third of the Earth's land surface and account for 80-90% of plant carbon and 30-40% of soil carbon. Forest carbon stocks and dynamics respond to and interact with global climate change (GCC). Recent tree ring research highlights the worsening impact of GCC and acid deposition on long-term forest productivity in central Europe. This pr ....Environmental fingerprints of biogeochemical cycles embedded in tree rings: Linking global climate change to local long-term forest productivity. Forests cover one-third of the Earth's land surface and account for 80-90% of plant carbon and 30-40% of soil carbon. Forest carbon stocks and dynamics respond to and interact with global climate change (GCC). Recent tree ring research highlights the worsening impact of GCC and acid deposition on long-term forest productivity in central Europe. This project seeks to develop and apply novel tree ring technologies for linking biogeochemical cycles of carbon and nutrients to long-term forest productivity in different regions, and to provide a scientific basis for accounting for long-term forest productivity and carbon stocks in response to future GCC.Read moreRead less
The abundance and isotope composition of pyrogenic carbon in tropical savannas. Tropical savanna burning represents an important but poorly understood component of the global carbon cycle. This project will quantify the dynamics of pyrogenic carbon (charcoal, soot, biochar) production and dispersal during savanna fires. Pyrogenic carbon is important because it can persist in the environment for thousands of years. Hence it represents both a 'sink' for carbon and a source of information about pas ....The abundance and isotope composition of pyrogenic carbon in tropical savannas. Tropical savanna burning represents an important but poorly understood component of the global carbon cycle. This project will quantify the dynamics of pyrogenic carbon (charcoal, soot, biochar) production and dispersal during savanna fires. Pyrogenic carbon is important because it can persist in the environment for thousands of years. Hence it represents both a 'sink' for carbon and a source of information about past environments. The project will also assist in validating 'biochar' as a new tool for carbon sequestration, an enable a deeper understanding of the interactions between fire, humans, vegetation and climate.Read moreRead less

Climate change and ocean acidification are widely recognized as key threats to Australia's natural ecosystems, yet we are currently ill-equipped to respond due to poor knowledge of the scale/nature of the impacts. The Heron Island Climate Change Observatory will establish key infrastructure that will rapidly improve our understanding of the impacts of ocean acidification which is important to local communities and the nation given that coral reefs support over $6 billion in revenue (and employ 60,000 people) each year. This critically important information is essential to the management and protection of Australia's coral reefs, including the Great Barrier Reef.

450 Million year history of plant gas exchange capacity and the role of atmospheric carbon dioxide. Our planet faces an increase in atmospheric carbon dioxide that is unprecedented in human history, but has occurred in ancient times. By studying the relationship between past changes in atmospheric carbon dioxide, plant gas exchange and climate we will gain powerful global insight into future scenarios of continental carbon and water fluxes. This global perspective is essential for Australia to a ....450 Million year history of plant gas exchange capacity and the role of atmospheric carbon dioxide. Our planet faces an increase in atmospheric carbon dioxide that is unprecedented in human history, but has occurred in ancient times. By studying the relationship between past changes in atmospheric carbon dioxide, plant gas exchange and climate we will gain powerful global insight into future scenarios of continental carbon and water fluxes. This global perspective is essential for Australia to assess its vulnerability to global climate change in relation to other nations, thereby informing national planning of landscape resource use, including primary industry, water infrastructure and carbon trading.Read moreRead less
The impact of ocean acidification on the fertilization, larval development and recruitment of key Australian marine organisms. This work will define the potential vulnerability for Australian marine ecosystems that arises from the rapid acidification of Australia's coastal environments by rising atmospheric carbon dioxide. Our preliminary data suggest that the early life history stages of a wide range of marine species are very sensitive to the impact of ocean acidification. At present, almost ....The impact of ocean acidification on the fertilization, larval development and recruitment of key Australian marine organisms. This work will define the potential vulnerability for Australian marine ecosystems that arises from the rapid acidification of Australia's coastal environments by rising atmospheric carbon dioxide. Our preliminary data suggest that the early life history stages of a wide range of marine species are very sensitive to the impact of ocean acidification. At present, almost nothing is known about the impacts and implications of these changes. Without this knowledge, however, we are in a poor position as a nation to respond and adapt to these changes. We plan to explore this vulnerability for Australian marine organisms and develop a detailed understanding of its implications for Australia's marine ecosystems and associated industries.
