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.

这个项目的目的是了解海洋环流的变化对海洋地球化学、气候和最终对南极冰盖的影响，方法是将对最后一次冰期循环进行的瞬时模拟与一个地球系统模型结合起来，该模型包括古代用记录的汇编。海洋环流在最后一个冰川周期（约140，000年）中发生了变化，预计由于大气中二氧化碳的增加，未来几个世纪将发生变化。该项目将利用最先进的高分辨率海洋碳循环模型，测量海洋环流在海洋酸化和氧含量方面的未来变化。这将导致更好地了解地球系统内的过程和反馈。
