Changes in the Southern Ocean abyssal circulation are linked with dramatic climate events, yet the associated dynamics are poorly understood. This project aims to determine the fundamental dynamic processes driving abyssal flows, and diagnose impacts of recent and projected climate change. The project also aims to bridge the large gap between conceptual and observational understanding of this vital limb of the ocean's overturning circulation. A significant innovation is that it will be the first study of the Southern Ocean abyss using realistic global-scale models capable of simulating all the key dynamic processes. Results will guide Southern Ocean observation programs, explain observed changes, and reduce uncertainties in climate projections.

南大洋深海环流的变化与戏剧性的气候事件有关，但相关的动力机制却鲜为人知。该项目旨在确定推动深海水流的基本动力过程，并诊断最近和预计的气候变化的影响。该项目还旨在弥合概念上和观测上对海洋颠覆环流的这一重要部分的理解之间的巨大差距。一项重大的创新是，这将是第一次使用能够模拟所有关键动态过程的现实的全球尺度模型来研究南大洋深渊。结果将指导南大洋观测计划，解释观察到的变化，并减少气候预测中的不确定性。
