In the past 50 000 years there were several episodes of abrupt climate change during which atmospheric carbon dioxide rose significantly. This project aims to determine the causes of past abrupt changes in atmospheric carbon dioxide. The project is significant because understanding changes in the global carbon cycle is essential to estimate future climate trajectories. Innovatively, it will highlight the relationship between Southern Hemisphere water masses and the marine carbon cycle during abrupt climate change. The expected outcomes include a better understanding of the interplay between Southern Ocean processes and the carbon cycle.

在过去的50000年里，有几次气候突变，在此期间，大气中的二氧化碳显着上升。该项目旨在确定过去大气二氧化碳突然变化的原因。该项目意义重大，因为了解全球碳循环的变化对于估计未来气候轨迹至关重要。创新性地，它将突出南半球水团和海洋碳循环在气候突变期间的关系。预期成果包括更好地了解南大洋进程与碳循环之间的相互作用。
