This project aims to be the first to develop new methods which will allow accurate study of light propagation effects. These methods remove the “noise” (light propagation effects) from observational data, resulting in unprecedented accuracy of the analyses and new insight into properties of dark energy. At the same time these methods use the “noise” as the actual signal to measure properties of the Universe, especially the mass distribution inside cosmic voids (places in the Universe avoided by galaxies), which will solve the problem of dark matter distribution inside cosmic voids. The project aims to use light propagation effects to test Einstein's theory of gravity at cosmological scales.Read moreRead less

This project aims to advance our ability to assess and monitor climate change across the Antarctic ocean/sea-ice system. Ocean/sea-ice interactions have a critical role in the global climate and there is an urgent need to determine how these are responding to climate change. This project will overcome gaps in existing observational datasets that currently limit our understanding of spatiotemporal variability and change in ocean around Antarctica. This study will use two new approaches, biotagging and autonomous platforms, to greatly improve our capacity to model and predict the impacts of climate change on the Antarctic ocean/sea ice system and beyond.Read moreRead less
The puzzle of landfast sea ice: ‘Fast’ ice and near-term climate impacts. Sea ice which is held motionless against the Antarctic coastline (so-called landfast, or 'fast' ice) is hugely important for global climate and Southern Ocean ecosystems but its extent has recently plummeted. This project will address major knowledge gaps by providing novel satellite-based mapping and analysis of fast ice extent, towards enabling incorporation of fast ice into Australia’s new sea ice-ocean Earth system mod ....The puzzle of landfast sea ice: ‘Fast’ ice and near-term climate impacts. Sea ice which is held motionless against the Antarctic coastline (so-called landfast, or 'fast' ice) is hugely important for global climate and Southern Ocean ecosystems but its extent has recently plummeted. This project will address major knowledge gaps by providing novel satellite-based mapping and analysis of fast ice extent, towards enabling incorporation of fast ice into Australia’s new sea ice-ocean Earth system model for the first time – to allow assessment of its impacts on global ocean circulation and ice shelf melt. Outcomes also include new automated capability for monitoring fast ice extent, analysis of its variability and drivers, and first maps of its thickness and roughness.Read moreRead less
Distribution of ocean heat uptake and its implications for sea level and climate change. Increasing sea levels and ocean temperatures provide critical evidence of long term warming of the climate system.

This project aims to analyse a 2000-year palaeoclimate record of single event and complex climate extremes to provide a long-term context for observed changes in climate extremes over recent decades. This project expects to generate new knowledge about long-term variability in the frequency and magnitude of climate extremes that occur on seasonal - decades time-scales. It also expects to provide information about complex extremes that involve multiple types of impacts (e.g. drought followed by flood, simultaneous drought and fire). Expected benefits of the project include improved understanding of climate extremes and improved risk estimates for the impacts of climate extremes on Australian government and industry infrastructure.Read moreRead less

The Antarctic Slope Current in a warming climate. Melting Antarctic ice sheets are responsible for 28% of global sea level rise in recent decades, and can contribute more than 1 metre of sea level rise by year 2100, and a staggering 15 metres by 2500. Increased glacial melt rates are best understood by studying changes in the circulation of water around the Antarctic coastline. The combination of physical processes that must be resolved in this region places a high demand on ocean observations a ....The Antarctic Slope Current in a warming climate. Melting Antarctic ice sheets are responsible for 28% of global sea level rise in recent decades, and can contribute more than 1 metre of sea level rise by year 2100, and a staggering 15 metres by 2500. Increased glacial melt rates are best understood by studying changes in the circulation of water around the Antarctic coastline. The combination of physical processes that must be resolved in this region places a high demand on ocean observations and modelling systems. This project uses a series of high-resolution ocean and ice experiments, cross-validated with observations, to provide a deeper understanding of how waters at the Antarctic margin respond to both anthropogenic and natural climate forcing.Read moreRead less
Environmental and behavioural approaches for parasite resistant aquaculture. In modern fish aquaculture, parasite infections threaten efficient production. Ecological problems also arise when fish farms amplify parasite populations and cause outbreaks in surrounding wild fish populations. Present control methods rarely integrate the behaviour of the host fish. This project aims to assess the behaviours of hosts and the mechanisms that lead to parasite outbreaks. It will develop behavioural appro ....Environmental and behavioural approaches for parasite resistant aquaculture. In modern fish aquaculture, parasite infections threaten efficient production. Ecological problems also arise when fish farms amplify parasite populations and cause outbreaks in surrounding wild fish populations. Present control methods rarely integrate the behaviour of the host fish. This project aims to assess the behaviours of hosts and the mechanisms that lead to parasite outbreaks. It will develop behavioural approaches that separate host and parasite, reduce infection, and altering host behaviour to improve the effectiveness of treatments and minimise their environmental impacts. This project aims to create novel methods to control parasites in ways that limit their ability to evolve resistance.Read moreRead less
