An investigation of why some of the bottom water originated in the Southern Ocean is not renewed in the world ocean will be conducted using historical data. This layer of unrenewed water sits between the heavier Atlantic Bottom Water and the lighter Antarctic Bottom Water. The respective role of thermobaric and cabelling instabilities in determining the depth and density to which the catastrophic overturning reaches will be examined.

将利用历史数据调查为什么一些起源于南大洋的底层水在世界海洋中没有更新。这层没有更新的水位于较重的大西洋底层水和较轻的南极底层水之间。温压不稳定性和舱室不稳定性在决定灾难性倾覆到达的深度和密度方面的各自作用将被研究。
