How iron is cycled in Southern Ocean waters. This project aims to probe the Southern Ocean phytoplankton’s ability to take up and retain iron, using iron isotope tracer techniques. The Southern Ocean regulates Earth's climate, but the supply of iron to Southern Ocean surface waters is low, restricting the ability of phytoplankton to flourish and draw down carbon dioxide. The results are expected to reveal survival strategies of phytoplankton in this iron-poor environment and their potential abil ....How iron is cycled in Southern Ocean waters. This project aims to probe the Southern Ocean phytoplankton’s ability to take up and retain iron, using iron isotope tracer techniques. The Southern Ocean regulates Earth's climate, but the supply of iron to Southern Ocean surface waters is low, restricting the ability of phytoplankton to flourish and draw down carbon dioxide. The results are expected to reveal survival strategies of phytoplankton in this iron-poor environment and their potential ability to adapt to environmental change. This knowledge could be used to develop models to manage this climate-sensitive region.Read moreRead less
Eddies: The key to understanding Southern Ocean carbon cycling. This project plans to observe an eddy in the Southern Ocean for three weeks, to understand how its circulation affects ocean productivity and the exchange of carbon dioxide between the ocean and atmosphere. Ocean eddies are like small high and low pressure weather systems which spin either clockwise or anticlockwise, are about 100–200 kilometres across and several hundred metres deep. Eddies are important because they generate verti ....Eddies: The key to understanding Southern Ocean carbon cycling. This project plans to observe an eddy in the Southern Ocean for three weeks, to understand how its circulation affects ocean productivity and the exchange of carbon dioxide between the ocean and atmosphere. Ocean eddies are like small high and low pressure weather systems which spin either clockwise or anticlockwise, are about 100–200 kilometres across and several hundred metres deep. Eddies are important because they generate vertical currents that move nutrients and carbon dioxide up and down. Expected project outcomes will include a better understanding of carbon cycling in an ocean region that is central to the climate of Australia and the rest of the planet.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

The researchers will integrate studies of zooplankton biodiversity from the tropics to the Southern Ocean with an optical plankton counter to quickly measure zooplankton size and approximate shape. This new technology, together with a resurgence in collaborative marine science through the Integrated Marine Observing System and the Sydney Institute of Marine Science, will enable Australian researchers to understand changes in the plankton in freshwater or in estuaries, as well as in the East Australian Current. This current has already strengthened and is predicted to be the area of greatest warming in the Southern Hemisphere. The response of plankton communities to these changes will have profound effects on Australian fisheries and livelihoods.Read moreRead less

There is strong public interest in both the Arctic and Antarctica and global climate change. By better understanding how these polar ecosystems function in winter and the likely effects of increasing temperatures we will be able to keep the public informed on likely impacts. There are large fishing industries in the Arctic and growing finfish and krill fisheries in the Southern Ocean. This project will contribute to a better understanding of how these stocks will be affected (together with seals, penguins and whales) and how they should be managed to ensure sustainable fisheries and maximum biodiversity.Read moreRead less
Robotic investigation of water optical properties in the Southern Ocean. The project aims to improve our understanding of light–matter interactions in the waters of the Southern Ocean (SO), in particular the role of phytoplankton and associated material of biological origin. Phytoplankton are the energy source for the food web and a critical component of carbon cycling in the SO. However, their dynamics in the SO cannot be quantified using satellite observations because bio-optical data processi ....Robotic investigation of water optical properties in the Southern Ocean. The project aims to improve our understanding of light–matter interactions in the waters of the Southern Ocean (SO), in particular the role of phytoplankton and associated material of biological origin. Phytoplankton are the energy source for the food web and a critical component of carbon cycling in the SO. However, their dynamics in the SO cannot be quantified using satellite observations because bio-optical data processing algorithms perform poorly due to a lack of field data. This project seeks to remedy this by improving understanding of SO bio-optics, and by providing novel algorithms of known uncertainty, based on in situ data.Read moreRead less
Coupled physical and biogeochemical dynamics on the Australian North West Shelf. Information regarding the natural function of the Australian North West Shelf is urgently required to sustainably manage the often conflicting uses of the region. This project will study the role of ocean processes in driving ocean productivity on the North West Shelf and determine the impact of projected climate variability.
Hot iron: Are submarine volcanoes important for Southern Ocean iron supply? The scarcity of iron limits biological productivity and carbon uptake in the nutrient rich waters of the Southern Ocean. This project will explore for the first time the role of undersea "hot spot" volcanoes in supplying iron to surface waters, thus linking the solid earth and the biosphere. The project will measure iron abundance, reactivity and nutritional value in buoyant plumes emanating from vents near Heard/McDonal ....Hot iron: Are submarine volcanoes important for Southern Ocean iron supply? The scarcity of iron limits biological productivity and carbon uptake in the nutrient rich waters of the Southern Ocean. This project will explore for the first time the role of undersea "hot spot" volcanoes in supplying iron to surface waters, thus linking the solid earth and the biosphere. The project will measure iron abundance, reactivity and nutritional value in buoyant plumes emanating from vents near Heard/McDonald Islands, Australia's only active volcanoes. The project aims to estimate the hydrothermal contribution to regional biological productivity and extrapolate to the whole Southern Ocean. Successful outcomes will benefit Australia by identifying iron sources that govern productivity and carbon uptake of an economically important ecosystem.Read moreRead less
