Southern Ocean productivity and carbon dioxide (CO2) exchange under current and future climate regimes. This project will contribute to Australian ocean science expertise in key areas of data synthesis, satellite oceanography and the understanding of marine ecosystems' response to climate change. Collaborations will be developed and strengthened among Australian research institutions, and between Australia and the United States.

This project will contribute to Australian ocean science expertise in key areas of data synthesis, satellite oceanography and the understanding of marine ecosystems' response to climate change. Collaborations will be developed and strengthened among Australian research institutions, and between Australia and the United States. The focus of the research is the Southern Ocean, which impacts global climate, and on which Australia's southern coastal ecosystems depend. The expertise and techniques developed will have application to other Australian regional seas.Read moreRead less
The ARC Earth System Science Research Network. The ARC Earth System Science Network incorporates data collectors, modellers and impacts researchers to address the impacts of climate change and variability on Human, biological and physical systems. Our capacity to adapt to changes in water availability, agricultural productivity, the likelihood of species extinctions, and risks to human health will be enhanced through the Network's use of frontier technologies. The enhanced capacity to use data a ....The ARC Earth System Science Research Network. The ARC Earth System Science Network incorporates data collectors, modellers and impacts researchers to address the impacts of climate change and variability on Human, biological and physical systems. Our capacity to adapt to changes in water availability, agricultural productivity, the likelihood of species extinctions, and risks to human health will be enhanced through the Network's use of frontier technologies. The enhanced capacity to use data and model the Earth System will allow policymakers to make more informed decisions with regard to water, biodiversity, human health, industry and agriculture sustainability; thereby enhancing the national capacity to respond to climate change and variability and securing our common interest.Read moreRead less
Iron in the Antarctic sea ice zone and its role in the past and future climate. The Antarctic sea ice environment has remained poorly investigated for decades as it is difficult to access. Recent scientific advances have revealed that melting sea ice may provide a significant amount of the plant micro-nutrient iron to the Southern Ocean. Given that polar waters are iron-deficient and seasonal sea ice affects ~14 million square kilometres of ocean, the importance of iron fertilisation from deca ....Iron in the Antarctic sea ice zone and its role in the past and future climate. The Antarctic sea ice environment has remained poorly investigated for decades as it is difficult to access. Recent scientific advances have revealed that melting sea ice may provide a significant amount of the plant micro-nutrient iron to the Southern Ocean. Given that polar waters are iron-deficient and seasonal sea ice affects ~14 million square kilometres of ocean, the importance of iron fertilisation from decaying sea ice and its effect on global climate urgently need to be evaluated. This proposal aims at improving our understanding of Earth's complex system, and will inform future climate change policy in Australia.

Summary
High performance computing for mathematics, chemistry, engineering and climate research. The aim of this proposal is to accelerate research across a range of disciplines using high performance computing which is currently limited by the present available computing power. These disciplines include: mathematical modelling of magnetic resonance imaging, computational chemistry, engineering fluid dynamics, climate system modelling including atmosphere, ocean and ice sheet simulations. The Univers ....High performance computing for mathematics, chemistry, engineering and climate research. The aim of this proposal is to accelerate research across a range of disciplines using high performance computing which is currently limited by the present available computing power. These disciplines include: mathematical modelling of magnetic resonance imaging, computational chemistry, engineering fluid dynamics, climate system modelling including atmosphere, ocean and ice sheet simulations. The University of Tasmania, the Antarctic CRC and Australian Antarctic Division are combining resources to share in a joint facility of much greater capability. The proposed new high performance computing facility will increase in the computational power (over a weighted average of our benchmarks) by 13, an 8 fold increase in memory, and a 10 fold increase in disk storage. This new facility will allow these research groups to maintain their internationally leading edge status in high performance computing.Read moreRead less
Impact of Metal - Reactive Oxygen Species (ROS) Interactions on Growth and Toxicity of Ichthyotoxic Algae in Australian Coastal Waters. Toxic algal blooms in estuarine and coastal waters can have devastating economic and ecological impacts but remarkably little is known about the factors that control either organism growth or toxin severity. Recent studies suggest that the interplay between delivery of the nutrient trace metals iron and copper and the method via which the organism acts to assimi ....Impact of Metal - Reactive Oxygen Species (ROS) Interactions on Growth and Toxicity of Ichthyotoxic Algae in Australian Coastal Waters. Toxic algal blooms in estuarine and coastal waters can have devastating economic and ecological impacts but remarkably little is known about the factors that control either organism growth or toxin severity. Recent studies suggest that the interplay between delivery of the nutrient trace metals iron and copper and the method via which the organism acts to assimilate these metals is critical to the generation and aggressiveness of the toxins produced. These processes will be investigated in this study and conceptual and mathematical models will be developed which will assist in assessing management options for estuarine and coastal environments.Read moreRead less
