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.

从面向澳大利亚西南部海底峡谷的南大洋 (SO) 收集的深海珊瑚和海水营养成分，将用于提供关于 SO 翻转环流在调节全球气候以及供应必需营养物质方面的作用的新见解这使得这些峡谷成为虎鲸和蓝鲸季节性聚集的生物多样性热点地区。这一前沿项目通过使用澳大利亚罕见的遥控潜水器（ROV）技术收集样本而成为可能，也将有助于了解二氧化硫环流如何影响过去的全球气候变化，以及它在快速变暖的世界中控制海洋生产力的未来作用。增加大气中的二氧化碳。
