The Southern Ocean's role in determining atmospheric CO2 levels: new insights from novel biogenic silica records of seawater pH

自工业革命以来，燃烧化石燃料产生的排放物约有一半已被海洋吸收。然而，海洋在未来继续吸收二氧化碳的后果和程度仍存在相当大的不确定性。这项研究将改善现有的有限知识，包括在表层和深层之间转移二氧化碳的关键生物和相关海洋过程，以及由于二氧化碳吸收而增加的海洋酸度对海洋生态系统的影响。这些知识将有助于预测未来气候变化的进程，并衡量其对海洋生物和生产系统的影响。

About half the emissions from the burning of fossil fuel since the Industrial Revolution have been absorbed by the oceans. However, considerable uncertainty surrounds the consequences of and the extent to which the oceans will continue to sequester CO2 into the future. This research will improve existing limited knowledge of the key biological and related ocean processes that transfer CO2 between the surface and depth, and the poorly understood effects on marine ecosystems of increasing ocean acidity due to CO2 absorption. This knowledge will contribute to predicting the course of future climate change and gauging the impacts on marine life and production systems.
