Ocean Acidification in a Rapidly Increasing CO2 World. Carbon dioxide not only acts as a greenhouse gas but is being dissolved at increasing rates into the surface waters of the world's oceans, causing ocean acidity. We will examine how the rapidly increasing trend towards acidity in the oceans surrounding Australia is effecting the ability of marine organisms to calcify and determine the rate at which the world's ocean sink for CO2 is being reduced. New constraints will be placed on the critica ....Ocean Acidification in a Rapidly Increasing CO2 World. Carbon dioxide not only acts as a greenhouse gas but is being dissolved at increasing rates into the surface waters of the world's oceans, causing ocean acidity. We will examine how the rapidly increasing trend towards acidity in the oceans surrounding Australia is effecting the ability of marine organisms to calcify and determine the rate at which the world's ocean sink for CO2 is being reduced. New constraints will be placed on the critical threshold limits of CO2 emissions for sustainable calcification in both shallow tropical and deep-water marine ecosystems of the Southern Oceans.Read moreRead less
Ocean response to tropical cyclone forcing on the Australian North West Shelf. Tropical cyclones are a major hazard for the offshore oil and gas industry. This project will develop the ability to predict the ocean response to tropical cyclones, leading to a paradigm shift in the way industry designs and operates both present and future offshore projects.

The Centre will revolutionise predictions of the future of East Antarctica and the Southern Ocean. Changes in the Antarctic will be profoundly costly to Australia, including sea-level and fisheries impacts; but the speed and scale of future change remains poorly understood. A new national-scale and interdisciplinary Centre is required to understand the complex interactions of the ocean, ice sheets, atmosphere and ecosystems that will govern Antarctica’s future. The Centre will combine new field data with innovative models to address Australia’s Antarctic science priorities, train graduate students, develop leaders, engage the public, and enable major economic benefit as Australia adapts to climate change in the coming years and beyond.Read moreRead less

The model will include the effects of tides, winds, surface gravity waves and density. The model results will be compared to field measurements collected by the Australian Institute of Marine Science. After the model has been developed and validated, it will be used to investigate processes such as water exchange between lagoons and open sea, effects of contaminant spills and recruitment within the reef systems. An understanding of these processes is essential for the sustainable management of these systems.Read moreRead less

This project aims to develop new technology for measuring ocean surface currents at unprecedented fine resolution using aerial imagery and theory that describes how surface waves are refracted by currents. The project will generate new knowledge on ocean surface current processes and variability across a range of scales, and critically, improve our understanding of surface current uncertainty through application of advanced statistical analysis techniques. The outcomes of this project will deliver Australian capability to leverage the enhanced spatial and temporal resolution of next generation Earth observations to directly benefit search and rescue, offshore industry operations, defence, and pollution response in Australian waters.Read moreRead less
Hydrodynamics of Fringing Reef Systems. Ningaloo Marine Park is part of the National Representative System of Marine Protected Areas. Coral reefs are in a state of decline worldwide, yet Ningaloo Reef has remained in a relatively pristine state. However, its close proximity to land makes it particularly vulnerable to human activities, which are forecast to significantly grow in the near future. Results from this project will advance our ability to predict circulation on reefs and other similar c ....Hydrodynamics of Fringing Reef Systems. Ningaloo Marine Park is part of the National Representative System of Marine Protected Areas. Coral reefs are in a state of decline worldwide, yet Ningaloo Reef has remained in a relatively pristine state. However, its close proximity to land makes it particularly vulnerable to human activities, which are forecast to significantly grow in the near future. Results from this project will advance our ability to predict circulation on reefs and other similar coastal systems. This will provide insight into various ecological processes that are linked to hydrodynamics (e.g. recruitment), and will provide a foundation for conducting risk analysis of processes that threaten the integrity of nearshore environments (e.g. contaminant spills).Read moreRead less
Tidal generation of internal waves and currents. The North West Shelf (NWS) is a region of great significance to Australia, due mainly to the presence of the multi-billion dollar oil and gas industry, but also for fishing and national defense issues.

Holding coral reefs together with soluble cement. This project aims to characterise and understand cement formation in coral reefs. Coral reefs are constructed by cementing together aragonite building blocks made by corals. The main cementing agent is high-magnesium calcite, the most soluble carbonate mineral and susceptible to ocean acidification. High-magnesium calcite cements are best developed on the high energy margins of coral reefs. This project will quantify how crustose coralline algae ....Holding coral reefs together with soluble cement. This project aims to characterise and understand cement formation in coral reefs. Coral reefs are constructed by cementing together aragonite building blocks made by corals. The main cementing agent is high-magnesium calcite, the most soluble carbonate mineral and susceptible to ocean acidification. High-magnesium calcite cements are best developed on the high energy margins of coral reefs. This project will quantify how crustose coralline algae produces high-magnesium calcite and controls the dissolution and reprecipitation of high-magnesium cements. This project intends to quantify rates of reef cementation, susceptibility to ocean acidification and warming, and possible mitigating effects of alkalinity addition.Read moreRead less
Ocean-reef interactions as drivers of continental shelf productivity in a changing climate. Poor coastal management results in the irreparable destruction of reef systems' function and biodiversity, nationally and globally. To manage marine resources effectively we must implement sustainable practices, including forward planning in the context of climate change.

Poor coastal management results in the irreparable destruction of reef systems' function and biodiversity, nationally and globally. To manage marine resources effectively we must implement sustainable practices, including forward planning in the context of climate change. A critical limitation in determining appropriate actions is a poor understanding of mechanisms driving productivity. Our project will provide key information on the oceanographic mechanisms supporting Australia's coastal systems, linking nutrient supply, physical drivers and climate. By linking all these factors we will both assist in determining appropriate ecosystem management, and provide a knowledge base to support adaptation to future changes in Australia's climate.Read moreRead less
