Iron in the Antarctic sea ice zone and its role in the past and future climate

几十年来，南极海冰环境的研究仍然很差，因为很难进入。 最近的科学进展表明，融化的海冰可能为南大洋提供大量的植物微量营养铁。 鉴于极地沃茨缺铁，季节性海冰影响约1400万平方公里的海洋，因此迫切需要评估腐烂海冰铁肥化的重要性及其对全球气候的影响。该提案旨在提高我们对地球复杂系统的认识，并将为澳大利亚未来的气候变化政策提供信息。

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.
