The overturning circulation of the oceans is a driver of large and surprisingly abrupt climate shifts. We aim to understand the factors that control the rate of overturning, and whether it might soon slow down or cease owing to global warming. We also aim to resolve one of the biggest conundrums in oceanography by reconciling theoretical and measured rates of mixing in the deep ocean. Improved knowledge of deep ocean dynamics, particularly in the Southern Ocean, will help us gauge the likely nature and pace of imminent climate changes in the Australian region, an essential step in assessing the impacts on water resources, ecosystems, agriculture, and energy demands. The research will add to a major new initiative in marine science at ANU.

海洋环流的翻转是大规模和令人惊讶的突然气候变化的驱动力。我们的目标是了解控制倾覆速度的因素，以及由于全球变暖，它是否会很快放缓或停止。我们还旨在通过协调深海混合的理论和测量速率来解决海洋学中最大的难题之一。加深对深海动力学的了解，特别是在南大洋，将有助于我们衡量澳大利亚地区即将发生的气候变化的可能性质和速度，这是评估对水资源、生态系统、农业和能源需求影响的重要一步。这项研究将为澳大利亚国立大学海洋科学的一项重大新举措增添内容。
