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.

自工业革命以来，燃烧化石燃料产生的排放量中，约有一半被海洋吸收。然而，围绕未来海洋将继续封存二氧化碳的后果和程度仍存在相当大的不确定性。这项研究将改善关于二氧化碳在表层和深层之间转移的关键生物过程和相关海洋过程的现有有限知识，以及二氧化碳吸收导致的海洋酸度增加对海洋生态系统的影响知之甚少。这些知识将有助于预测未来气候变化的进程，并衡量对海洋生物和生产系统的影响。
