Deep-sea coral and seawater nutrient profiles collected from the Southern Ocean (SO) facing submarine canyons of south-west Australia will be used to provide new insights into the role of the SO overturning circulation in modulating global climate as well as supplying the essential nutrients that make these canyons biodiversity hot-spots for seasonal aggregations of killer and blue whales. This frontier project made possible by samples collected using Remote Operated Vehicle (ROV) technology rarely available in Australia, will also help to understand how SO circulation has influenced past changes in global climate and its future role in controlling ocean productivity in a warming world with rapidly increasing atmospheric carbon dioxide.

从南大洋（SO）面向澳大利亚西南部海底峡谷收集的深海珊瑚和海水营养概况将用于提供新的见解，以了解SO翻转环流在调节全球气候方面的作用，以及提供必要的营养物质，使这些峡谷成为虎鲸和蓝鲸季节性聚集的生物多样性热点。这个前沿项目通过使用澳大利亚很少使用的遥控飞行器（Remote Operated Vehicle，简称OVM）技术收集的样本成为可能，也将有助于了解SO环流如何影响过去的全球气候变化，以及它在控制海洋生产力方面的未来作用。
