项目摘要

This ESH award will support a team of investigators to address three separate project, each combining the use of radiochemical dating techniques (14C, 230Th and 231Pa) with stable isotope and trace element analysis of corals and speleothems. Projects include: (1) Calibration of the radiocarbon time scale between 10,000 and 48,000 years BP using previously-collected corals from Papua New Guinea and speleothems from the Bahamas; (2) Establish a high-resolution climated record for the mid-continent of North America from Missouri speliothems; (3) Determine the age and sea-level history for the Penultimate deglaciation (Termination II) using coral outcrops in Barbados.

该 ESH 奖项将支持一个研究团队完成三个独立的项目，每个项目都将放射化学测年技术（14C、230Th 和 231Pa）与珊瑚和洞穴的稳定同位素和微量元素分析结合起来。项目包括： (1) 使用先前采集的巴布亚新几内亚珊瑚和巴哈马洞穴化石，校准距今 10,000 年至 48,000 年的放射性碳时间尺度； (2) 利用密苏里洞穴生物建立北美中部大陆的高分辨率气候记录； (3) 利用巴巴多斯的珊瑚露头确定倒数第二次冰消（终止 II）的年龄和海平面历史。
