Deep-sea coral records of Southern Ocean climate and nutrient dynamics

从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剖面将用于提供SO翻转环流在调节全球气候中的作用的新见解，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。这个前沿项目是通过使用远程操作车辆（ROV）技术收集的样品而实现的，这种技术在澳大利亚很少使用，也将有助于了解SO循环如何影响过去的全球气候变化，以及在大气二氧化碳迅速增加的变暖世界中，SO循环在控制海洋生产力方面的未来作用。

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.
