The key role of the Southern Ocean in atmospheric CO2 sequestration

本研究提出的综合方法旨在量化过去海洋生产力的变化及其在控制过去大气CO2变化中的作用。这将通过研究南大洋的深海沉积物来实现，南大洋是全球海洋生物泵中具有根本重要性的关键区域。这项研究将增进我们对海洋生物区系、海洋碳循环和全球气候之间联系的了解，为更可靠地预测最近大气二氧化碳迅速增加的影响提供基础。将彻底评估涉及海洋浮游植物的可能补救办法，以解决二氧化碳过量问题。

The integrated approach proposed in this study aims to quantify past changes in marine productivity and its role in controlling past atmospheric CO2 variations. This will be achieved by studying deep sea sediments from the Southern Ocean, a key area with a fundamental importance in the global ocean biological pump. This research will enhance our understanding of the linkages connecting marine biota, the ocean carbon cycle and global climate, providing the basis for more reliable predictions about the impacts of the recent rapid atmospheric CO2 increase. Possible remediation solutions involving marine phytoplankton to this CO2 excess will be thoroughly assessed.
