Antarctica's leaky defence to poleward heat transport

南大洋洋流是海洋向南极洲输送热量的障碍。这一屏障在路径上的关键位置被破坏，向极地的热输送得到加强。不断变化的风预计会加速热传输，威胁到保护南极冰川免受海洋驱动融化的冰架。该项目旨在促进对控制南大洋热传输的小尺度过程的理解。通过将利用观测系统新进展的国际实地活动与下一代数值模拟相结合，这项研究将在我们预测南大洋环境变化的能力方面产生一个阶段性的变化。

Southern Ocean currents are barriers to the oceanic transport of heat toward Antarctica. This barrier breaks down at key locations along their path and the poleward heat transport is enhanced. Changing winds are expected to accelerate heat transport, threatening ice shelves that protect Antarctic glaciers from ocean-driven melt. This project aims to advance understanding of the small-scale processes that control heat transport across the Southern Ocean. By combining funded international field campaigns that harness new advances in observing systems with next-generation numerical modelling, this research will create a step-change in our ability to predict Southern Ocean environmental change.
