The Southern Ocean plays a critical role in the uptake of heat and carbon dioxide from the atmosphere into the deep ocean. This uptake depends strongly on mixing processes due to ocean eddies, which are especially important in regions of steep topography, leading to localised mixing hot spots. These ocean eddies have scales of 10-100km and therefore can not be resolved in current global climate models. This project will examine these mixing processes using a combination of observations and innovative modelling approaches. This knowledge will be used to improve the representation of eddy processes in state-of-the-art climate models, which will ultimately allow Australia to more effectively respond to the challenge of climate change.

南大洋在将热量和二氧化碳从大气中吸收到深海方面发挥着关键作用。这种吸收强烈依赖于海洋涡旋引起的混合过程，这在地形陡峭的地区尤其重要，导致局部混合热点。这些海洋涡旋的尺度为10-100公里，因此在目前的全球气候模式中无法解决。该项目将结合观察和创新的建模方法来研究这些混合过程。这些知识将用于改进最先进气候模型中的涡旋过程表示，这最终将使澳大利亚能够更有效地应对气候变化的挑战。
