Mid-depth Atlantic circulation during the Last Glacial Maximum and deglaciation

点击翻译按钮获取中文摘要

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.
