Dust to the ocean: Does it really increase productivity?

本项目旨在研究扬尘与海洋生产力之间的关系。该项目将通过使用新的地球化学技术和具有自主海洋传感器的新方法，量化海洋中的粉尘沉积及其化学和生态影响。该项目的预期成果包括改进对海洋尘埃沉积的估计，以及开发全球适用的方法，利用剖面浮标量化尘埃与生物之间的联系。这应该会带来显著的好处，例如用于预测未来营养物沉积变化的改进的尘埃模型，对预测未来海洋鱼类产量和碳吸收具有重要意义。

This project aims to investigate the relationship between dust deposition and marine productivity. This project will quantify dust deposition to the ocean and its chemical and ecological impact by using new geochemical techniques and novel approaches with autonomous ocean sensors. Expected outcomes of this project include improved estimates of dust deposition to the ocean and the development of globally-applicable methods for quantifying the link between dust and biology using profiling floats. This should provide significant benefits such as improved dust models used to predict future changes in nutrient deposition, with implications for predicting future ocean fish production and carbon uptake.
