Resolving the role of kelp in blue carbon cycles to enable management. We aim to uncover how kelp forests contribute to carbon storage, biodiversity enhancement and nutrient mitigation in Australia. We will combine mapping and modelling to identify local variation in kelp carbon stocks and sequestration potential and verify kelp carbon export to deep ocean sinks through genetic tracing in seawater and sediments. Co-benefits will be identified through nutrient experiments and reef surveys. We wil ....Resolving the role of kelp in blue carbon cycles to enable management. We aim to uncover how kelp forests contribute to carbon storage, biodiversity enhancement and nutrient mitigation in Australia. We will combine mapping and modelling to identify local variation in kelp carbon stocks and sequestration potential and verify kelp carbon export to deep ocean sinks through genetic tracing in seawater and sediments. Co-benefits will be identified through nutrient experiments and reef surveys. We will also assess the risk that calcification and production of halogenic gas within the kelp forest could offset its climate mitigation potential. Project outcomes will enable management to consider kelp ecosystem services broadly and optimize our capacity to meet current emission reduction and biodiversity commitments.Read moreRead less
Genomics and mixed source populations in wildlife translocations. Translocation is a conservation strategy to help the plight of endangered species, and is becoming increasing important to mitigate against climate change. However translocations often fail. Theory suggests mixing individuals from different source populations would benefit species' genomic diversity and potentially success rates, however this is untested in animals. Also unclear is what parts of the genome are important for mitiga ....Genomics and mixed source populations in wildlife translocations. Translocation is a conservation strategy to help the plight of endangered species, and is becoming increasing important to mitigate against climate change. However translocations often fail. Theory suggests mixing individuals from different source populations would benefit species' genomic diversity and potentially success rates, however this is untested in animals. Also unclear is what parts of the genome are important for mitigating against climate change. Using an endangered lizard model, this project aims to understand how to best start new populations by 1) providing the first empirical test in terrestrial vertebrates of using mixed source populations; and 2) uncovering regions of the genome important for considering in translocations.Read moreRead less

A balancing act: Resolving coastal wetland water, carbon and solute fluxes. Coastal wetlands offer an impressive capacity to regulate the Earth’s climate by altering the way carbon dioxide is extracted from the atmosphere and stored while simultaneously influencing the water cycle, thus providing ecosystem services such as carbon storage, abating flood waters, improving water quality and protecting the coastline from sea level rise. This project aims to address the current gaps in understanding .... A balancing act: Resolving coastal wetland water, carbon and solute fluxes. Coastal wetlands offer an impressive capacity to regulate the Earth’s climate by altering the way carbon dioxide is extracted from the atmosphere and stored while simultaneously influencing the water cycle, thus providing ecosystem services such as carbon storage, abating flood waters, improving water quality and protecting the coastline from sea level rise. This project aims to address the current gaps in understanding the critical exchanges of water and greenhouse gases (GHGs) combining field methodologies and hydrological models, under different climatic conditions. The intended outcomes will benefit management of GHG emissions, coastal flooding and vulnerable groundwater dependent habitats.Read moreRead less

There is an untapped potential to reduce greenhouse gas emissions from millions of Australian farm dams. This project aims to quantify the nation-wide carbon footprint of farm dams and develop low-cost strategies for “greener” practices. Contributing to Australia’s commitment to tackle climate change, this project aspires to empower farmers to significantly reduce the carbon footprint of their farm dams. It will also inform on the economic viability of alternative management strategies for mitigating farm dam emissions and provide recommendations for financial incentives. This project should enhance the capacity of Australia to meet its carbon reduction targets and mitigate anthropogenic climate change.Read moreRead less
Linking microstructural evolutions across the scales of granular failure. This project expects to transform the understanding of granular materials and their behaviour by establishing explicit links between the macroscopic responses of the materials and their evolving microstructural properties. This should lead to revolutionary constitutive models for granular materials that possess true mechanisms of evolving grain-scale structures.

This project expects to transform the understanding of granular materials and their behaviour by establishing explicit links between the macroscopic responses of the materials and their evolving microstructural properties. This should lead to revolutionary constitutive models for granular materials that possess true mechanisms of evolving grain-scale structures. The proliferation of these new models should allow development of reliable predictive computational tools for the modelling and assessment of field-scale failure involving granular materials, enhancing the capability to assess the integrity and stability of earth structures, and benefitting the Australian economy, environment and public safety.Read moreRead less
Proppant transport in non-Darcy fracture flow for reservoir integrity/yield. Hydro-fracking of a typical gas well in Australia consumes around 3000 tonnes of proppants to keep open the created fractures, costing over $1.5 million. This project investigates proppant transport behaviour in non-Darcy turbulent flow during fracking of underground reservoir rock by combining Hele-Shaw-cell experiments with Particle Image Velocimetry and conceptual/numeric modelling.

Hydro-fracking of a typical gas well in Australia consumes around 3000 tonnes of proppants to keep open the created fractures, costing over $1.5 million. This project investigates proppant transport behaviour in non-Darcy turbulent flow during fracking of underground reservoir rock by combining Hele-Shaw-cell experiments with Particle Image Velocimetry and conceptual/numeric modelling. The generating advanced proppant transport knowledge is expected to be more accurate than laminar flow-based theories currently relied on. Expected outcomes include more efficient/safer proppant-assisted fracking strategies to reduce wasteful proppant disposition and inform industry/government management of fracking based on the reservoir geological features.Read moreRead less
