This project aims to develop a numerical circulation model applicable to fringing reef systems, in particular, the Ningaloo reef, Western Australia. 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
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. A critical limitation in determining appropriate actions is a poor understanding of mechanisms driving productivity. Our project will p ....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. 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
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
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

This project aims to create a floating, mobile fisheries and oceanographic observing system for Eastern Australia. Australian oceanographic and fisheries research has been hampered by the lack of appropriately sized and equipped research vessels required to investigate continental shelf waters and beyond. The automated floating facility will provide data to support ongoing ARC-funded research programs in marine biogeochemistry, climate change, ocean acidification, coastal hydrology, biological oceanography, active acoustics, and fisheries resources and technology in the continental shelf and beyond. The expected outcome will bridge a major gap in fisheries and oceanographic research capacity to make observations in a critical region of the Australian marine estate and provide a stronger scientific basis for early detection of changes in seawater chemistry, biology and fisheries in priority waters experiencing rapid change.Read moreRead less

Coral reefs are at the frontline from the effects of rapidly rising levels of carbon dioxide that is causing both global warming and oceans to become more acid-like. Our research program will determine how the survival of one of the World’s most pristine and best preserved coral reefs, Ningaloo Reef, is linked to the response of Australia’s Indian Ocean to climate change. For the first time, we will simulate realistic ‘future’ conditions and see how actual coral reef systems respond. This will provide a ‘yardstick’ against which the best-case survival potential of the world’s coral reefs can be assessed, critical for underpinning the urgently needed action to reduce greenhouse gas emissions if we are to ensure the survival of coral reefs.Read moreRead less

Are corals able to control their calcification in a changing ocean? The project aims to develop a new understanding of fundamental mechanisms responsible for coral calcification and its ability to acclimate to global warming and ocean acidification. Mineral skeleton formation by coral is the key process controlling the creation of reef structures upon which entire ecosystems depend.

The project aims to develop a new understanding of fundamental mechanisms responsible for coral calcification and its ability to acclimate to global warming and ocean acidification. Mineral skeleton formation by coral is the key process controlling the creation of reef structures upon which entire ecosystems depend. Despite the importance of coral to the function of reef ecosystems, how calcification works mechanistically within coral itself, and why small modifications of their physical and chemical habitat can have large effects on growth is presently poorly understood. This project seeks to provide this basic knowledge to improve our ability to assess the future of corals and help policy-makers take adequate measures to preserve coral reefs.Read moreRead less
