The scarcity of iron in the Southern Ocean limits biological productivity and carbon uptake. There is currently very little Information on zooplankton iron content, yet available data points to high variability. This variability is leading to poor predictive outcomes for models of Southern Ocean iron and carbon cycling. Our project addresses this knowledge gap by quantifying zooplankton iron content and examining its biogeochemical and ecological impact on Southern Ocean productivity. Developing an understanding of how iron is cycled through zooplankton will provide significant benefits including improved global models used to quantify current and future patterns of ocean productivity critical for environmental and economic predictions.

南大洋铁的缺乏限制了生物生产力和碳吸收。目前关于浮游动物铁含量的信息很少，但现有数据表明变化很大。这种可变性导致南大洋铁和碳循环模型的预测结果很差。我们的项目通过量化浮游动物铁含量并研究其对南大洋生产力的地球化学和生态影响来解决这一知识差距。了解铁是如何通过浮游动物循环的，将带来巨大的好处，包括改进用于量化海洋生产力当前和未来模式的全球模型，这对环境和经济预测至关重要。
