Summary
The role of Antarctic sea ice as a natural ocean fertiliser. This project will assess the importance of sea ice as a natural fertiliser in the climatically important polar region. The knowledge gained will aid climate modellers and Governmental policy-makers concerned with the commercial use of ocean iron fertilisation as an attempt to reduce human-induced atmospheric carbon dioxide and gain carbon credits.
Ocean fertilisation: a positive effect from Antarctica’s great thaw? This project will evaluate how the Antarctica's great thaw may fertilise the Southern Ocean with iron and help mitigate carbon dioxide emissions now and in the future. The Southern Ocean is anaemic, meaning that the iron levels are too low to sustain photosynthesis, a pathway by which the oceans transform carbon dioxide into carbon-rich sediments. There is evidence that melting ice may supply substantial amount of iron, capable ....Ocean fertilisation: a positive effect from Antarctica’s great thaw? This project will evaluate how the Antarctica's great thaw may fertilise the Southern Ocean with iron and help mitigate carbon dioxide emissions now and in the future. The Southern Ocean is anaemic, meaning that the iron levels are too low to sustain photosynthesis, a pathway by which the oceans transform carbon dioxide into carbon-rich sediments. There is evidence that melting ice may supply substantial amount of iron, capable of boosting marine life and removing carbon dioxide. As polar regions show the earliest and most severe impacts of anthropogenic activity, studying ice-ocean interactions is central to supporting national and international policy development that can effectively limit the worst impacts of climate change globally.

Summary
The Australian Centre for Excellence in Antarctic Science. 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 gov ....The Australian Centre for Excellence in Antarctic Science. 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
