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 ability to adapt to environmental change. This knowledge could be used to develop models to manage this climate-sensitive region.

该项目旨在利用铁同位素示踪技术探索南大洋浮游植物吸收和保留铁的能力。南大洋调节着地球的气候，但南大洋表层水域的铁供应量较低，限制了浮游植物的繁盛和吸收二氧化碳的能力。研究结果有望揭示浮游植物在缺铁环境中的生存策略及其适应环境变化的潜在能力。这些知识可用于开发模型来管理这个气候敏感地区。
