It is crucial that Australia remains a world leader in marine biology and ecology and continues to preserve the uniqueness of its marine environment through the development of integrated inter-disciplinary research projects. This project will open a new area of research at both the national and international levels through the first integrated approach of the behavioural mechanisms that rule the base of the ocean food web structures and functions. The present work is also expected to open new perspectives in fields such as biological oceanography, microbial ecology, plankton ecology, behavioural ecology through the exploration of previously untapped areas of research.Read moreRead less
Three-dimensional mapping and bio-physical coupling in the plankton microenvironment. The fate of carbon in the marine environment, and potential modification of global climate, is driven by organisms ranging in size from 0.1 to 100 µm interacting at mm to cm scales. This research will provide the first high-resolution 3D measurements of distributions, diversity and dynamics of these key organisms. Australia provides the unique opportunity to study these microscale patterns and processes in arch ....Three-dimensional mapping and bio-physical coupling in the plankton microenvironment. The fate of carbon in the marine environment, and potential modification of global climate, is driven by organisms ranging in size from 0.1 to 100 µm interacting at mm to cm scales. This research will provide the first high-resolution 3D measurements of distributions, diversity and dynamics of these key organisms. Australia provides the unique opportunity to study these microscale patterns and processes in archetypical examples of environments representative of the world's most significant marine ecosystems. These results will maintain Australia at the cutting-edge of marine environmental science, and provide the first application of novel sampling, analysis and modelling techiques to environments of the Australian economic exclusion zone.Read moreRead less

Summary
Assimilation of ocean wave interactions with sea ice into climate models. Contemporary climate models do not accurately portray ocean or atmosphere interactions where the open ocean meets the expanses of floating sea ice within the polar regions, as they lack a component to determine the size of ice floes. This project will tackle the omission directly, developing from modelling advances made in recent years.
Sediment transport in upwelling currents and its relevance to an active petroleum system in the Morum Sub-basin, South Australia. Australia had a trade deficit of $3.5 billion in petroleum products in 2005 and this is forecast to increase dramatically in the future. Giant oil fields may exist in the Morum Sub-basin and their exploitation could significantly reduce Australia's trade deficit in petroleum products. It would also reduce Australia's reliance on oil form politically unstable parts of ....Sediment transport in upwelling currents and its relevance to an active petroleum system in the Morum Sub-basin, South Australia. Australia had a trade deficit of $3.5 billion in petroleum products in 2005 and this is forecast to increase dramatically in the future. Giant oil fields may exist in the Morum Sub-basin and their exploitation could significantly reduce Australia's trade deficit in petroleum products. It would also reduce Australia's reliance on oil form politically unstable parts of the globe. Any exploration activity and subsequent exploration success would have a significant effect on the rural economy based around Portland, the main port in the area, through which most of the logistics would flow.Read moreRead less
Microscale insights into ocean-scale processes: microbial behaviour as a driver of ocean biogeochemistry. Microscopic plankton regulate the ocean's chemical cycles, which ultimately support life on earth. However, the ecological interactions driving these processes are poorly understood. This project will use novel approaches to decipher the behaviours of marine microbes, providing a more complete perception of how ocean ecosystems operate and influence climate.

Australian national facility for noble-gas radio-isotope measurements:
This facility is designed to provide researchers with the ability to accurately date water and ice cores using the natural radio-isotopes in the sample. Radiocarbon dating has been a revolutionary tool in providing answers to a range of questions in anthropology, archaeology and the earth sciences. However, radiocarbon dating has a strong limitation in that it can only date periods from 1000–50 000 years: the use of radioactive noble-gas isotopes can extend this range out to 1 year to 1 million years. This capability in the new facility is expected to support new understanding of processes in artesian reservoirs, ocean currents and geology that may affect questions of water availability, climate and environmental change.Read moreRead less
MICROSCALE PLANKTON AND PARTICLE DYNAMICS: COMPARING AND CONTRASTING AUSTRALIAN AND INTERNATIONAL SEAS. Microscopic phytoplankton are the basis of ocean ecosystems, but most predictions and measurements focus on processes that occur over kilometres.

Microscopic phytoplankton are the basis of ocean ecosystems, but most predictions and measurements focus on processes that occur over kilometres. Our recent work shows that definite and regular submetre seascape topography exists. This grant will test the extent to which this seascape topography is the fundamental organisational unit of marine ecosystems and the extent to which it characterises Australian coastal waters and open ocean water masses. This research takes a leadership role in defining and advancing our understanding of how marine ecosystems function. The project will bring over $200 million of Japanese infrastructure to Australia for 3 years.Read moreRead less
The role of pulsed water events in structuring marine benthic communities along the southern Australian coastline. Marked differences in benthic community structure have been observed that are associated with pulsed cold-water events, possibly driven by internal wave phenomena. Such events have the potential to act as very important controls on both regional and local patterns of benthic biodiversity. To date, however, their effects and mechanisms of action have never been examined in Australi ....The role of pulsed water events in structuring marine benthic communities along the southern Australian coastline. Marked differences in benthic community structure have been observed that are associated with pulsed cold-water events, possibly driven by internal wave phenomena. Such events have the potential to act as very important controls on both regional and local patterns of benthic biodiversity. To date, however, their effects and mechanisms of action have never been examined in Australia. The fundamental outcome from this project will be the first assessment of the occurrence, geographical extent and ecological consequences of pulsed water phenomena along the southern Australian coastline.Read moreRead less

This work will open a new area of research within Australian habitats, which will improve our understanding of how the base of the ocean food web functions, and build a new perspective from which to look at the microscopic plankton that influence fisheries yield and species invasions. Appreciating how microbial communities respond to environmental perturbations will provide an improved vantage-point to predict future changes to the Australian marine environment. Leading international scientists will provide conceptual and technical expertise in an Australian based project, applying novel analytical tools not currently employed within oceanographic surveys within Australian waters.Read moreRead less
