Ocean fertilisation: a positive effect from Antarctica’s great thaw?

该项目将评估南极洲的大融化如何为南大洋提供铁，并帮助减少现在和未来的二氧化碳排放。南大洋是贫血的，这意味着铁含量太低，无法维持光合作用，而光合作用是海洋将二氧化碳转化为富含碳的沉积物的途径。有证据表明，融化的冰可能提供大量的铁，能够促进海洋生物的生长并去除二氧化碳。由于极地地区受到人类活动最早和最严重的影响，研究冰海相互作用对于支持国家和国际政策制定至关重要，这些政策可以有效地限制全球气候变化的最严重影响。

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.
