This project aims to improve our understanding of the role of convection on the Antarctic margins using a high-resolution, cutting-edge numerical approach. Convection is an important, but poorly understood oceanic process, which diverts heat away from the melting Antarctic ice shelves by transporting cold and salty water from the ocean surface to depth. The project outcomes will be new knowledge of the physics from novel numerical models and theory, supported by insights from observations and model parameterisations. This timely research will improve prediction of sea level rise due to a changing Antarctica and enhance our ability to adapt to future climate scenarios, providing significant environmental and health benefits to Australians.

该项目旨在通过高分辨率、尖端的数值方法提高我们对南极边缘对流作用的理解。对流是一个重要的海洋过程，但人们对其了解甚少，它通过将寒冷和咸水从海洋表面输送到深处，将热量从融化的南极冰架转移出去。项目成果将是来自新的数值模型和理论的物理学新知识，并得到观测和模型参数化的见解的支持。这项及时的研究将改进对由于南极洲变化而导致的海平面上升的预测，并增强我们适应未来气候情景的能力，为澳大利亚人提供重大的环境和健康效益。
