The history of ocean circulation at the intermediate water depth remains controversial, limiting our understanding of the interplay of ocean circulation, climate changes, and the global carbon cycle. This project aims to generate trace elemental and isotopic records for 10 key locations in the Atlantic Ocean, which constrain physicochemical properties of water masses at unprecedented temporal resolution during the last glacial maximum and the subsequent deglaciation. This multi-proxy approach will reconcile controversy and pin down the evolution of mid-depth Atlantic circulation in the past, and thereby substantially improve our understanding of the climate system.

中层水深海洋环流的历史仍然存在争议，限制了我们对海洋环流、气候变化和全球碳循环相互作用的理解。该项目旨在为大西洋的10个关键地点生成痕量元素和同位素记录，以前所未有的时间分辨率限制最后一次冰盛期和随后的冰川消融期间水团的物理化学性质。这种多代理方法将调和争议并确定过去大西洋中深层环流的演变，从而大大提高我们对气候系统的理解。
