Iron in the Antarctic sea ice zone and its role in the past and future climate. The Antarctic sea ice environment has remained poorly investigated for decades as it is difficult to access. Recent scientific advances have revealed that melting sea ice may provide a significant amount of the plant micro-nutrient iron to the Southern Ocean. Given that polar waters are iron-deficient and seasonal sea ice affects ~14 million square kilometres of ocean, the importance of iron fertilisation from deca ....Iron in the Antarctic sea ice zone and its role in the past and future climate. The Antarctic sea ice environment has remained poorly investigated for decades as it is difficult to access. Recent scientific advances have revealed that melting sea ice may provide a significant amount of the plant micro-nutrient iron to the Southern Ocean. Given that polar waters are iron-deficient and seasonal sea ice affects ~14 million square kilometres of ocean, the importance of iron fertilisation from decaying sea ice and its effect on global climate urgently need to be evaluated. This proposal aims at improving our understanding of Earth's complex system, and will inform future climate change policy in Australia.

Targeting organically-complexed iron species in seawater using selective solid-phase adsorbent resins. Iron limits primary productivity in 40% of the oceans. Its accurate determination is thus critical to understanding the functioning of marine ecosystems and their role in moderating Earth's climate. Recent findings indicate that serious discrepancies exist in iron concentrations obtained using different analytical methods. These discrepancies are believed to be due to the lability of organic ....Targeting organically-complexed iron species in seawater using selective solid-phase adsorbent resins. Iron limits primary productivity in 40% of the oceans. Its accurate determination is thus critical to understanding the functioning of marine ecosystems and their role in moderating Earth's climate. Recent findings indicate that serious discrepancies exist in iron concentrations obtained using different analytical methods. These discrepancies are believed to be due to the lability of organic and colloidal iron species to extraction by adsorbent preconcentration resins. This project will design and synthesise a range of functionalised resins for the selective extraction of iron species from seawater, advancing our knowledge of its bioavailability and leading to the generation of class-specific analytical methodologies.Read moreRead less

This project aims to investigate the relationship between dust deposition and marine productivity. This project will quantify dust deposition to the ocean and its chemical and ecological impact by using new geochemical techniques and novel approaches with autonomous ocean sensors. Expected outcomes of this project include improved estimates of dust deposition to the ocean and the development of globally-applicable methods for quantifying the link between dust and biology using profiling floats. This should provide significant benefits such as improved dust models used to predict future changes in nutrient deposition, with implications for predicting future ocean fish production and carbon uptake.Read moreRead less
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.

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
Natural iron fertilisation of oceans around Australia: linking terrestrial dust, marine biogeochemistry and climate. Oceans play a vital role in Earth’s climate through the control of atmospheric carbon dioxide. An important component of this system is the iron cycle, in which iron-rich dust is transported from the land via atmosphere to ocean; iron is a key micronutrient for marine phytoplankton, the scarcity of which limits essential biogeochemical processes and ocean fertility. This project w ....Natural iron fertilisation of oceans around Australia: linking terrestrial dust, marine biogeochemistry and climate. Oceans play a vital role in Earth’s climate through the control of atmospheric carbon dioxide. An important component of this system is the iron cycle, in which iron-rich dust is transported from the land via atmosphere to ocean; iron is a key micronutrient for marine phytoplankton, the scarcity of which limits essential biogeochemical processes and ocean fertility. This project will conduct an integrated oceanographic and atmospheric observational program for trace elements in the oceans around Australia. This will provide the critical information on iron supplied from atmospheric dust for ocean productivity and marine ecosystem health, providing the science for predicting a key factor in the future impact of the oceans on climate.Read moreRead less
