Past to future changes in ocean dynamics and biogeochemistry

该项目旨在通过将对上一次冰川周期的瞬变模拟与地球系统模型结合起来，并结合古替代记录的汇编，了解海洋环流的变化对海洋生物地球化学、气候以及最终对南极冰盖的影响。海洋环流在上一次冰川周期(约14万年)中发生了变化，预计在未来几个世纪将由于大气二氧化碳的上升而发生变化。该项目将使用最先进的高分辨率海洋碳循环模型来测量未来海洋环流对海洋酸化和含氧量的变化。这将有助于更好地理解地球系统内的过程和反馈。

This project aims to understand the impact of changes in ocean circulation on marine biogeochemistry, climate and ultimately the Antarctic ice-sheet by combining transient simulations of the last glacial cycle performed with an Earth system model incorporating the compilation of paleoproxy records. The oceanic circulation has varied over the last glacial cycle (~140,000 years) and is expected to change over the coming centuries due to rising atmospheric carbon dioxide. The project will measure future changes in oceanic circulation on ocean acidification and oxygen content with a state-of-the-art high-resolution ocean carbon cycle model. This will lead to improved understanding of processes and feedbacks within the Earth system.
