The project aims to predict the ocean carbon dioxide sink’s long-term capacity and future trajectories of global warming and increasing carbon dioxide. This project will use geochemical proxies encoded in the skeletons of deep-sea corals in the Perth Canyon, Tasman seas, and Antarctica, in the heart of the ocean-climate system, to reveal continuous long-term records of environmental change at annual-decadal resolution for our recent past (hundreds to thousands of years) and the Last Glacial Maximum. These records are expected to provide a more accurate understanding of Earth’s long-term responses to anthropogenic carbon dioxide emissions and global warming.

该项目旨在预测海洋二氧化碳汇的长期容量以及全球变暖和二氧化碳增加的未来轨迹。该项目将使用在珀斯峡谷、塔斯曼海和南极洲的深海珊瑚骨架中编码的地球化学代用物，在海洋-气候系统的中心，揭示我们最近（数百年至数千年）和末次盛冰期环境变化的连续长期记录。这些记录有望更准确地了解地球对人为二氧化碳排放和全球变暖的长期反应。
