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.
The krill pump: transferring carbon across a layered ocean in a changing climate. Krill may have an important role in temperate oceanic ecosystems, and rise to the surface to feed at dusk, competing with other zooplankton and being eaten by commercial fish species. Their response to a rapidly warming ocean is a key unknown, especially with currents off eastern Australia warming 2.5 degrees Celsius by 2100.
Understanding multi-scale dynamics of eddies in the East Australian Current. This project aims to provide the first rigorous quantification of the complex dynamics of rotating eddies (the weather systems of the ocean) and fronts on scales ranging from metres to 100s of kilometres and hours to weeks in the East Australian Current System. This project is at the frontier of oceanographic research and will provide significant new understanding of the physical and biogeochemical dynamics of eddies an ....Understanding multi-scale dynamics of eddies in the East Australian Current. This project aims to provide the first rigorous quantification of the complex dynamics of rotating eddies (the weather systems of the ocean) and fronts on scales ranging from metres to 100s of kilometres and hours to weeks in the East Australian Current System. This project is at the frontier of oceanographic research and will provide significant new understanding of the physical and biogeochemical dynamics of eddies and their interactions across multiple spatio-temporal scales, revealing their impacts on productivity along Australia’s most populous coastline. This will provide significant benefits such as improved ocean forecasting and sustainable management of Australian marine industries and seafood sector, supporting economic growth. 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
A unique integrated approach to predicting fisheries recruitment. This projects plans to explore the causes of the worldwide decline in the highly lucrative spiny lobster fisheries that has occurred in recent decades. This decline has been attributed to ocean warming, however, the exact mechanism contributing to the demise of lobsters is not known. This project will use a hierarchy of oceanic models of increasing complexity combined with a unique spiny lobster data set to investigate the relatio ....A unique integrated approach to predicting fisheries recruitment. This projects plans to explore the causes of the worldwide decline in the highly lucrative spiny lobster fisheries that has occurred in recent decades. This decline has been attributed to ocean warming, however, the exact mechanism contributing to the demise of lobsters is not known. This project will use a hierarchy of oceanic models of increasing complexity combined with a unique spiny lobster data set to investigate the relationship between larval health, physiology and environmental variables and how this affects survival and successful recruitment into the fishery. An understanding of these complex relationships is expected to enable the first predictions of larval survival and settlement in a region of accelerated ocean warming, and provide critical information for sustainable fisheries management.Read moreRead less
Indian Ocean Climate Change: Ningaloo Reef, a litmus test for the survival of coral reefs. 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 simula ....Indian Ocean Climate Change: Ningaloo Reef, a litmus test for the survival of coral reefs. 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
Hydrodynamics of Intermittently Closing and Opening Lakes and Lagoons. Intermittently closing and open lakes and lagoons are shallow coastal water bodies that are connected intermittently to the ocean. Sixty of the 135 estuaries in New South Wales are considered to be ICOLL's. The closure of the Lake/Lagoon entrance to the ocean prevents water exchange that can lead to poor water quality. Detailed field and numerical model studies in two ICOLLS (Coila Lake and Wamberal Lagoon) are proposed us ....Hydrodynamics of Intermittently Closing and Opening Lakes and Lagoons.

Sixty of the 135 estuaries in New South Wales are considered to be ICOLL's. The closure of the Lake/Lagoon entrance to the ocean prevents water exchange that can lead to poor water quality. Detailed field and numerical model studies in two ICOLLS (Coila Lake and Wamberal Lagoon) are proposed using modern instrumentation. It is recognised that a fundamental understanding of the circulation and mixing characteristics of ICOLLs is imperative for the development of proper management strategies for these systems.Read moreRead less
Probing the response of Southern Ocean phytoplankton to changes in iron biogeochemistry, light and pH associated with climate change. Determining factors that influence the health and vitality of coastal and open-ocean regions is crucial to maintaining marine biodiversity and the Earth’s climatic balance. This research project will determine the role climate change and ocean acidification will have on the ability of Southern Ocean phytoplankton to flourish.
Transitions in wave breaking from deep to shallow water . The predominant impact on coastal geomorphology, marine safety and coastal structures is from breaking waves, especially from storms. This project will provide the first unified formulation of breaking wave effects from deep to shallow water, which will increase wave forecast model accuracy and hence improve coastal zone design and safety outcomes.

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
