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

几十年来，由于很难进入南极海冰环境，对它的调查一直很少。最近的科学进展表明，海冰融化可能会为南大洋提供大量的植物微营养铁。鉴于极地水域缺铁，季节性海冰影响约1400万平方公里的海洋，迫切需要评估腐烂海冰对铁的肥化及其对全球气候的影响。这项建议旨在提高我们对地球复杂系统的理解，并将为澳大利亚未来的气候变化政策提供参考。

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.
