The Southern Ocean's response to abrupt climate change

该项目旨在通过对海洋沉积物岩心进行地球化学分析，确定南大洋如何对气候突变作出反应。最后一个冰河时代的快速变暖事件提供了一个类似于人类引起的变暖。利用海洋气候模型进行的实验将评估南大洋不同部分和区域生物地球化学反应的驱动因素和后果。 预期成果是更好地了解气候变化如何以及为什么影响具有重要生态意义的南大洋的海洋生产力。这将导致在气候模型中更好地表示碳反馈，并对未来气候变化进行更有力的预测。

This project aims to determine how the Southern Ocean responds to abrupt climate change, through geochemical analysis of marine sediment cores. Rapid warming events of the last ice age provide an analogue to human-caused warming. Experiments using ocean climate models will evaluate the drivers and consequences of the biogeochemical response of different sectors and zones of the Southern Ocean. The intended outcome is a better understanding of how and why climate change impacts ocean productivity in the ecologically significant Southern Ocean. This will lead to better representations of carbon feedbacks in climate models and more robust projections of future climate change.
