该项目将分析从浮游生物、沉积物捕集器和从南大洋收集的沉积物样本中提取的浮游和底栖虫体内的微量金属。目的是评估Cd、Ba、Mg和Sr作为环境条件示踪剂的潜力,以及成岩作用的程度。下岩心研究将用于产生末次间冰期旋回期间南大洋表层和深层水的新的高分辨率古化学记录。
英文摘要
This project will analyze trace metals in planktic and benthic forminifera from plankton, sediment-trap, and sediment samples collected from the Southern Ocean. The goal is to assess the potential of Cd, Ba, Mg and Sr as tracers of environmental conditions, and the degree of diagenetic effects. Downcore studies will be used to produce new high-resolution paleochemical records of surface and deep Southern Ocean waters during the last glacial.interglacial cycle.
