Deep Atlantic’s role in millennial atmospheric carbon dioxide changes

该项目旨在通过生成过去15万年的第一个高分辨率大西洋深处碳酸盐离子和营养物质记录，填补全球碳循环研究中的一个关键知识空白。该项目将获得海气二氧化碳交换信号，从而可以直接评估大西洋深处在各种气候条件下千年大气二氧化碳变化中的作用。该项目的预期结果是大大提高我们对控制全球碳循环机制的理解。这将带来显著的好处，包括对用于预测未来由人为二氧化碳造成的全球变暖的模式进行评估。

This project aims to fill in a critical knowledge gap in global carbon cycle research, by generating the first high-resolution deep Atlantic carbonate ion and nutrient records for the last 150,000 years. The project will derive air-sea carbon dioxide (CO2) exchange signals, which permit straightforward evaluation of the deep Atlantic’s role in millennial atmospheric CO2 changes under various climate conditions. The intended outcome of this project is to substantially improve our understanding of the mechanisms that govern the global carbon cycle. This should provide significant benefits including the assessment of models used to predict future global warming due to anthropogenic CO2.
