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.

该项目旨在通过生成过去15万年来第一个高分辨率的大西洋深层碳酸盐离子和营养记录，填补全球碳循环研究中的一个关键知识空白。该项目将获得大气-海洋二氧化碳(CO2)交换信号，从而能够直接评估深海大西洋在各种气候条件下千禧年大气二氧化碳变化中的作用。该项目的预期结果是大幅提高我们对管理全球碳循环的机制的理解。这应该会带来巨大的好处，包括评估用于预测人为二氧化碳造成的未来全球变暖的模型。
